What it is01
What is Protoflow? A prostate support supplement in capsules
Protoflow is a prostate support supplement in capsule form, distributed by PhytoThrive Labs and sold for healthy prostate and urinary flow support. One serving is 2 capsules with water, and each 60-capsule bottle lasts 30 days.
The bottle holds 60 capsules. The Supplement Facts panel sets one serving at 2 capsules, so a bottle lasts 30 days. The front reads "Optimal Flow Support†", and the dagger points to the standard FDA statement that the claim has not been evaluated (FDA, Structure/Function Claims).
Inside are 14 label lines. Two are vitamins, vitamin E at 13 mg and niacin at 75 mg. The other twelve are plants and one nutrient, inosine. Every line has a printed amount, which is more than many supplements offer. The total is 1,619 mg across the day's two capsules.
The prostate is a small gland below the bladder. As men age it often grows, which is called BPH, and that can mean a weaker stream and more trips to the bathroom at night (NIDDK, Enlarged Prostate (BPH)). A capsule cannot shrink that growth on its own, so the fair question is whether these ingredients can help symptoms at the margin.
Claims vs evidence02
Does Protoflow really give 24/7 prostate support?
No. No study measured round-the-clock prostate support, and nobody has tested Protoflow itself. The sales page uses strong lines such as 24/7/365 support, while the bottle uses careful support wording with the FDA dagger.
No study measured round-the-clock support, and nobody has tested Protoflow. The sales page uses strong lines. The bottle is more careful.
The sales page makes big promises and shows no sources for them. We list each one in quotes, next to what the label and the research show.
The bottle itself uses "support" wording with the FDA dagger. That is the wording the law allows for supplements that are not reviewed before sale (FDA, Dietary Supplements Q&A).
- Headline“24/7/365 Prostate Support”No study measured round-the-clock support, and no trial tested Protoflow. The one prostate herb on the label is saw palmetto, which reviews find little or no help for urinary symptoms. (NCCIH, Saw Palmetto) (Tacklind et al., Cochrane 2012)
- Product labelA “Vital prostate wellness formula”'Vital' is marketing. The bottle itself says only 'Optimal Flow Support†' and never names the prostate. (Protoflow bottle label) (FDA, Structure/Function Claims)
- Function claimIt supports “the normal functions of the bladder, prostate and reproductive system”A function claim, allowed with the FDA disclaimer. Urinary symptoms can come from BPH, infection, diabetes, medicines or cancer, so a checkup matters more than a capsule. (FDA, Structure/Function Claims) (NIDDK, Enlarged Prostate (BPH))
- Completeness“Designed to offer complete support”No supplement gives complete support. Two of the 14 lines are vitamins, and eight botanical lines have little human research. (NIH ODS, Dietary Supplements: What You Need to Know)
- Fillers“100% free of chemical coating and other non-essential fillers”The label lists rice flour, gelatin, magnesium stearate, silicon dioxide, maltodextrin, soy protein concentrate and water as other ingredients. (Protoflow bottle label)
- Diet“Non-GMO, vegan and gluten-free”A gelatin capsule is not vegan. Soy protein concentrate is a major allergen. No non-GMO or gluten-free certificate is shown. (Protoflow bottle label) (FDA, Food Allergies)
- TestimonialsThree stories about better sleep and fewer night-time tripsAnecdotes, and the page itself says 'Results May Vary'. The FTC bans fake reviews and says testimonials need real evidence behind them. (FTC, Consumer Reviews and Testimonials Rule Q&A) (FTC, Health Products Compliance Guidance)
- SavingsSavings figures shown beside each packThese compare with struck-through prices this site does not show. What counts is the per-bottle price: $79, $59 or $49. (Protoflow info page)
- Bonus ebooks“10 Ways To Turbocharge Your Testosterone” and “1-Day Detox Guide”We have not read the ebooks. Their titles make promises that nothing on the label supports; low testosterone is diagnosed with blood tests. (MedlinePlus, Male Hypogonadism) (MSK, Tribulus terrestris)
Claims as printed on the sales page (Protoflow info page) and the bottle (Protoflow bottle label). A health claim needs competent and reliable scientific evidence, generally from human trials of the same product (FTC, Health Products Compliance Guidance).
Keep taking prescribed medicine
Do not stop or cut a prostate, blood pressure, heart or diabetes medicine because you started a supplement. Talk to the doctor who prescribed it first. More on side effects and supplements and medicines.
How you take it03
How do you take Protoflow capsules?
Take 2 Protoflow capsules a day with water. That is one serving on the panel and the most the label allows. The label does not say morning or night, so pick one time you will remember and keep it steady.
Take 2 capsules a day with water. That is one serving on the panel, and the most the label allows.
The side panel says adults take two capsules daily with water, and to consult a physician first if you take any medication (Protoflow bottle label). It does not say morning or night, and the front's "Day & Night Formula†" adds no schedule. Pick one time you will remember and keep it steady.

2 capsules, once a day, with water
That is one serving on the Supplement Facts panel. The label gives no time of day; keep it the same hour each day so it is easy to track.

Keep prescriptions on schedule
A supplement does not replace a prostate, blood pressure or heart medicine. Ask before changing anything.
- 04
Check in at day 30 and day 60
Note night-time bathroom trips and stream strength. The guarantee runs 60 days from receipt, and a doctor visit is worth booking either way.
What one serving is
Two capsules make one serving, and the bottle holds 30 servings. Niacin at 75 mg can cause a warm, red flush, which is a known effect of supplemental niacin above its upper limit (NIH ODS, Niacin). Taking the capsules with water and a meal may feel gentler. The full routine sits on the how to take it page.
Ingredients04
Protoflow Ingredients List: all 14 label lines with amounts
Protoflow has 14 label lines: vitamin E, niacin, hawthorn, epimedium, damiana, muira puama, ginkgo, Chinese ginseng, tribulus, catuaba, saw palmetto, inosine, oat straw and cayenne. Hawthorn and epimedium are the largest at 250 mg each.
Fourteen label lines: vitamin E, niacin, hawthorn, epimedium, damiana, muira puama, ginkgo, Chinese ginseng, tribulus, catuaba, saw palmetto, inosine, oat straw and cayenne.
Hawthorn and epimedium are the largest amounts at 250 mg each. Saw palmetto, the one herb with a long record in prostate research, is one of the smallest at 84.5 mg. That matters, because the big trials of saw palmetto used 320 mg a day and up (Barry et al., JAMA 2011 (CAMUS)).
Niacin at 75 mg is 469% of the Daily Value, and above the 35 mg a day upper limit for supplemental niacin (NIH ODS, Niacin). Vitamin E at 13 mg is 87% of the Daily Value, as d-alpha tocopheryl succinate (NIH ODS, Vitamin E). The capsule shell is gelatin, and soy protein concentrate is listed, so the product is not vegan and carries a soy flag.
- 1Vitamin E (as D-alpha tocopheryl succinate)13 mg per 2 capsules · 87% DV
- 2Niacin (Vitamin B3)75 mg per 2 capsules · 469% DV

The label05
What does the Protoflow label actually say?
The Protoflow label has a Supplement Facts panel with a serving of 2 capsules and 30 servings, 14 lines with amounts, the directions, and front-of-bottle claims. The panel is the legal record, and the front is marketing.
Numbered spots on the Supplement Facts panel, the directions and the bottle front. Tap a number to read that part in plain words.
The panel is the legal record of what is in a serving (21 CFR 101.36 (eCFR)). The front is marketing, held to looser rules, so "High Potency" is a phrase with no fixed meaning.
Tap a number to read that part of the panel.
- Serving size
2 capsules per serving and 30 servings: 60 capsules, a 30-day bottle.
- Vitamin E
13 mg as D-alpha tocopheryl succinate, 87% of the Daily Value. About 19 IU. The big prostate-cancer trial used 400 IU of a different form, so this is far lower.
- Niacin
75 mg, 469% DV. NIH sets 35 mg as the upper limit for niacin from supplements, so this is about twice that; the form is not printed.
- Hawthorn
250 mg of fruit. Studied for heart failure with extracts, not for the prostate.
- Epimedium
250 mg of whole plant, tied for the biggest botanical line. Its marketing story rests on lab work.
- Damiana
200 mg of leaf, a traditional aphrodisiac with almost no trials.
- Muira puama
200 mg of root, the 'potency wood'. Evidence is thin.
- Ginkgo
120 mg of leaf. Bleeding risk with blood thinners is the main caution.
- Chinese ginseng
120 mg of root. Can change blood sugar and weaken warfarin.
- Tribulus
120 mg of fruit, sold for testosterone. No clear rise shown in men.
- Catuaba
84.5 mg of bark. Lab studies only.
- Saw palmetto
84.5 mg of fruit. Trials used 320 mg a day of extract, and reviews find no benefit for BPH symptoms.
- Inosine
50 mg. The body turns it into uric acid, a point for anyone with gout.
- Oat straw
32 mg of stalks. No gluten-free statement is printed.
- Cayenne
20 mg of fruit, the smallest line.
- Footnote
The asterisk means no Daily Value exists for that ingredient.
- Other ingredients
Rice flour, gelatin, magnesium stearate, silicon dioxide, maltodextrin, soy protein concentrate, water. Gelatin means not vegetarian; soy is an allergen.
And the front of the bottle?
The render below is the bottle the brand shows. Its dark green label, lime ring and side icons suggest strength and energy, but the label makes no written claim about either.
Tap a number to read that part of the bottle front.
- Cap and seal
The directions panel says not to use the product if the safety seal is damaged or missing.
- The name
PROTO FLOW inside a lime ring, in the same colors as the site's logo.
- High Potency
There is no legal standard for this phrase. Several lines sit below the doses used in studies.
- Day & Night Formula†
The directions say two capsules daily with water and give no day-or-night schedule.
- Optimal Flow Support†
A support claim with the FDA dagger. It does not name a condition and nobody has tested the product.
- Dietary Supplement
The legal category. Supplements are not approved by FDA before sale.
Dose vs research06
Are the Protoflow doses as high as the studies?
For saw palmetto, no: the label has 84.5 mg and the trials used 320 mg or more. For niacin the label runs over the safe limit for supplements.
A dose match does not prove a product works, but a big shortfall makes a benefit less likely. A Cochrane review of 32 trials found saw palmetto did no better than placebo for urine flow or symptom scores (Tacklind et al., Cochrane 2012). The CAMUS trial then tried 320 mg, 640 mg and 960 mg a day in 369 men and found no gain over placebo at any dose (Barry et al., JAMA 2011 (CAMUS)).
For ginkgo and ginseng, NIH says there is no conclusive evidence that ginkgo helps any condition, and human evidence for ginseng is limited and mostly low quality (NCCIH, Ginkgo) (MSK, Ginseng (Asian)).
| Ingredient | Evidence | What it found |
|---|---|---|
| Saw palmetto | Cochrane review, 32 trials (Tacklind et al., Cochrane 2012) | No better than placebo for peak flow or symptom score in BPH |
| Saw palmetto, higher doses | CAMUS trial, 369 men (Barry et al., JAMA 2011 (CAMUS)) | No difference from placebo at 320, 640 or 960 mg a day |
| Vitamin E | NIH fact sheet (NIH ODS, Vitamin E) | A large trial linked 400 IU a day to more prostate cancer; the label has about 19 IU |
| Tribulus | MSK review (MSK, Tribulus terrestris) | Marketed as testosterone-like; the evidence does not clearly support it |
| Epimedium | MSK review (MSK, Epimedium) | Traditional use; studies are needed to verify effects |
Bottle claims07
What do the Protoflow support claims promise?
The bottle makes three claims in words and shows icons for strength and energy. Here is each one next to what studies of the ingredients found.
A "support" claim describes how a nutrient affects the body's normal structure or function. It does not need FDA approval, but the seller must be able to back it up and must print the FDA disclaimer (FDA, Structure/Function Claims).
- Bottle claim 1
The bottle shows“High Potency”
What the evidence saysThere is no legal definition. The saw palmetto line is 84.5 mg a serving against 320 mg a day in trials, and the 75 mg of niacin is about twice the 35 mg upper limit for supplement niacin. (Barry et al., JAMA 2011 (CAMUS)) (NIH ODS, Niacin)
- Bottle claim 2
The bottle shows“Day & Night Formula†”
What the evidence saysThe directions say two capsules daily with water and give no day-or-night split. Nothing on the label ties any ingredient to the day or the night. (Protoflow bottle label)
- Bottle claim 3
The bottle shows“Optimal Flow Support†”
What the evidence says'Flow' hints at urine flow, but the label names no condition. Saw palmetto, the one prostate herb, showed little or no benefit for BPH symptoms in a 32-trial Cochrane review and in the CAMUS trial. Nobody has tested Protoflow. (Tacklind et al., Cochrane 2012) (Barry et al., JAMA 2011 (CAMUS)) (NCCIH, Saw Palmetto)
- Bottle claim 4
The bottle shows“Male symbol, muscle and lightning icons”
What the evidence saysThe side strip's icons suggest strength and energy. The label makes no written claim about either, and tribulus and epimedium rest on lab work or mixed trials. (MSK, Tribulus terrestris) (MSK, Epimedium)
Claims as printed on the bottle front; the daggers point to the FDA statement (FDA, Structure/Function Claims).
Safety08
Protoflow side effects: who should check with a doctor before taking it?
Anyone on a blood thinner, heart or blood pressure medicine, diabetes medicine, a prostate medicine or an ED pill, and anyone with a soy allergy or urinary warning signs.
The bigger questions are interactions and the herbs. Ginkgo may raise bleeding risk in people on blood thinners (NCCIH, Ginkgo), hawthorn may interfere with digoxin and add to blood pressure drugs (MSK, Hawthorn), and epimedium has a long traditional use but little safety data (MSK, Epimedium). FDA has also found hidden sildenafil and tadalafil in products sold for male sexual performance (FDA, Alpha-Male public notification). We found no sign of that for Protoflow, but a label alone cannot prove it.
Six questions follow. A yes means a talk with your doctor or pharmacist first, or extra care.
Check a medicine
Not on this list. Ask your pharmacist; the list is not complete.
- Warfarin, apixaban (Eliquis), aspirin and other blood thinnersAsk first
Ginkgo with warfarin is linked to more major bleeding, ginseng's effect on warfarin is mixed, and large doses of vitamin E can add to bleeding. Ask your prescriber before you start. (NCCIH, Herb-Drug Interactions) (NCCIH, Ginkgo) (MSK, Ginseng (Asian)) (NIH ODS, Vitamin E)
- Nitrates, blood pressure and heart medicines (including digoxin)Ask first
Lab data suggest hawthorn may interfere with digoxin and add to antiplatelet effects; epimedium has been linked to rapid irregular heartbeat and should be avoided in heart disease; cayenne may alter blood pressure drugs. Ask your doctor first. (MSK, Hawthorn) (MSK, Epimedium) (MSK, Cayenne)
- Erectile dysfunction medicines (sildenafil, tadalafil, vardenafil)Ask first
Tadalafil is not for people who take nitrates, and both drug families have their own warnings. Epimedium is sold for the same goal. Tell your doctor about every product, and note that FDA has found hidden sildenafil and tadalafil in some 'natural' sexual-enhancement products. (MedlinePlus, Tadalafil) (MSK, Epimedium) (FDA, Alpha-Male public notification)
- Tamsulosin, alfuzosin, finasteride, dutasterideUse care
No interaction with the label ingredients is documented in the sources we checked. Finasteride and dutasteride lower PSA, and saw palmetto is not shown to change it. Do not swap a prescribed prostate medicine for a supplement. (MedlinePlus, Tamsulosin) (NCI, PSA Test Fact Sheet) (NCCIH, Saw Palmetto)
- Diabetes medicines (insulin, glipizide, metformin)Ask first
Ginseng may lower blood sugar too far with insulin or sulfonylureas, and damiana may affect blood sugar in animal studies. Ask your doctor first and know the signs of a low. (MSK, Ginseng (Asian)) (MSK, Damiana)
- Gout medicines (allopurinol, colchicine)Use care
Inosine turns into uric acid, which may be hazardous for people at risk of gout. Mention it to the prescriber who manages your gout. (UofM Health (Healthwise), Inosine)
- Prostate cancer treatment or active surveillanceAsk first
A large trial linked 400 IU a day of vitamin E to a higher prostate cancer risk. The label's 13 mg is much lower, but ask your urologist or oncologist about any supplement. (NIH ODS, Vitamin E) (NCI, PSA Test Fact Sheet)
- Medicines that can cause urinary retention (antihistamines, decongestants, opioids)Use care
These can worsen trouble emptying the bladder, which is the problem some men hope a prostate supplement will fix. A supplement does not offset them; ask your pharmacist. (NIDDK, Urinary Retention)
A short list built from NIH, MSK, FDA and trial sources, not a full interaction check. Bring the bottle or the Supplement Facts panel to your pharmacist. Keep taking prescribed medicine.
When to get help09
When are urinary symptoms an emergency?
Blood in the urine, burning with fever, pain in the groin or back, or not being able to pass urine need a doctor. Not being able to urinate at all needs emergency care.
Those signs can point to infection, stones, a blockage or cancer. A weak stream and night-time trips are common as men age, and BPH is the usual cause (NIDDK, Enlarged Prostate (BPH)), but the same symptoms can come from diabetes, medicines or infection (MedlinePlus, Nocturia). No supplement belongs in that plan.
- Blood in the urinePink, red or cola-colored urine
- Burning, fever or chillsPossible infection of the bladder or prostate
- Cannot empty the bladderA weak stream that is getting worse fast, or leaking
- Pain in the groin, testicles or lower backSudden or severe pain needs a doctor today
- Cannot urinate at allWith a swollen, painful lower belly: emergency
Most casesWaking at night, a slower stream or urgency are common as men age, and BPH is the usual cause. Still book a visit: the same symptoms can come from infection, diabetes, medicines or cancer, and a PSA test or exam is a talk to have with a clinician.
Call 911Or go to the emergency room if you cannot urinate at all, or have severe pain in the lower belly or groin. Sudden inability to pass urine is a medical emergency.
Signs from NIDDK (NIDDK, Urinary Retention) and (NIDDK, Enlarged Prostate (BPH)) and MedlinePlus (MedlinePlus, Nocturia). A supplement is never a reason to wait.
For everyday symptoms, guidelines put lifestyle steps first, such as less fluid and caffeine in the evening (AUA BPH Guideline (Sandhu 2023 amendment)). Read prostate basics and support options.
Verdict10
What are the pros and cons of Protoflow?
A fully printed label and low-priced six-packs, against no product trial, a low saw palmetto dose and a sales page that claims more than the evidence shows.
Our view: Protoflow is a reasonable thing to discuss with your doctor if you are curious about these herbs, and a poor reason to delay a checkup or change a prescription.
Pros
- All 14 lines have printed amounts
- Clear directions: 2 capsules a day with water
- 60-day money-back guarantee
- From $49 a bottle on the 6-pack, free US shipping on 3 or 6
- The label never names a disease
Cons
- No trial of the product itself
- Saw palmetto at 84.5 mg, below trial doses, and trials show little benefit anyway
- Niacin 75 mg is above the 35 mg supplement limit
- Gelatin and soy on the label; sales page says vegan
- Sales copy claims more than the evidence shows

Protoflow Reviews: what buyers say
A review goes up only once it matches a real order and the buyer agrees. None is verified yet, so the cards below are open slots.
The vendor supplied customer photos, and each card shows one small. The names, ratings and stories in the seller's sample copy are not verified, so they stay out. The FTC bans fake reviews and testimonials (FTC, Consumer Reviews and Testimonials Rule Q&A).

Badges and photos14
What do the Protoflow badges and product photos tell you?
The badges on the Protoflow page, such as FDA registered facility and money-back guarantee, describe the seller's paperwork and policy, not product approval. None of the material we could read names a factory, an auditor or a GMP certificate.
A row of seller badges and the bottle's front-of-bottle phrases, each with what it does and does not prove.
None of the material we could read names a factory, an auditor or a GMP certificate. Registering a food facility with FDA is paperwork, and it does not mean FDA approves the product (FDA, Registration of Food Facilities guidance).
Money-back guarantee
Matches the sales page's 60-day guarantee. Return shipping is on the buyer.
FDA registered facility
Registering a facility with FDA is paperwork. It is not an approval of the product, and the sales page names no facility.
GMP certified
No GMP certificate, auditor or date is published. Supplement makers must follow GMP rules by law, so the phrase alone proves little.
Doctor formulated
No doctor is named on the bottle or the sales page, so there is nothing to check.
Made in USA
The label prints a US distributor address but no place of manufacture.
100% natural ingredients
Plant parts are listed, but so are gelatin, magnesium stearate, silicon dioxide and maltodextrin. 'Natural' has no legal definition for supplements.
GMO free
No non-GMO certification is shown, and soy protein concentrate is on the label without a source.
Gluten free
The label prints no gluten-free statement or certification; oat straw and maltodextrin are on the panel.
Dairy free
No milk ingredient is listed. Soy protein concentrate is, so soy-allergic buyers should read the label.
Vegetarian
The label lists gelatin, an animal product, so we do not treat the capsules as vegetarian or vegan.
High Potency
There is no legal standard for this phrase. Several lines sit below the doses used in studies.
Day & Night Formula†
The directions say two capsules daily with water and give no day-or-night schedule.
Optimal Flow Support†
A structure/function-style claim with the FDA dagger. It is not a treatment claim and nobody has tested the product.
The badge images come with the vendor's image set; the rest are words printed on the bottle. A badge or a phrase is a claim by the seller, not a certificate. FDA does not approve supplements before they are sold (FDA, Dietary Supplements Q&A), and health claims in ads need real evidence (FTC, Health Products Compliance Guidance).
Product images
Product images from the vendor's set. They show packaging, not outcomes. (Protoflow info page)
Pack renders
Computer renders of the same bottle. Count the bottles on the order page, not in the picture. (Protoflow bottle label)
Brand marks
Brand graphics. A seal or a logo row is a seller claim, not a certificate. (Protoflow info page)

What is Proto Flow used for?
Proto Flow, usually written Protoflow, is a capsule dietary supplement sold for prostate and urinary flow support. One serving is 2 capsules, a bottle holds 60, and each serving lists vitamin E, niacin and 12 plant or nutrient lines, led by hawthorn and epimedium at 250 mg each.
What are the main ingredients in Protoflow?
The main Protoflow ingredients are hawthorn and epimedium at 250 mg each, damiana and muira puama at 200 mg each, ginkgo, Chinese ginseng and tribulus at 120 mg each, and catuaba and saw palmetto at 84.5 mg each. The label adds vitamin E, niacin, inosine, oat straw and cayenne.
Does Protoflow work, and how long should I try it?
Protoflow is made to support urinary flow with 14 label ingredients, including hawthorn, epimedium, ginseng and saw palmetto, at 2 capsules a day. Its best-known prostate herb, saw palmetto, has been tested on its own in large reviews and the CAMUS trial (Tacklind et al., Cochrane 2012) (Barry et al., JAMA 2011 (CAMUS)), which found little or no benefit for urinary symptoms, and the label holds 84.5 mg per serving. The full Protoflow formula has its own mix of 14 lines, and results vary from man to man, so track changes over the 60-day guarantee window.
Does Protoflow have side effects?
Possible effects come from the label ingredients. Niacin at 75 mg can cause flushing, itching and burning of the skin, ginkgo may raise bleeding risk with blood thinners, and a soy allergy matters. Stop and ask a doctor if urinary warning signs appear.
Who should not take Protoflow?
The page says do not use Protoflow if you are pregnant, nursing or under 18. Ask a doctor first if you take a blood thinner, heart or blood pressure medicine, diabetes medicine, a prostate medicine or an ED pill, or if you have a soy allergy.
How many Protoflow capsules a day?
Two, per the Supplement Facts panel: one serving, with water. Do not take more than the label says, because niacin is already above the 35 mg supplement limit (NIH ODS, Niacin).
Is Protoflow FDA approved?
No. The FDA does not approve dietary supplements before they are sold, and the bottle's claims carry the standard FDA disclaimer (FDA, Dietary Supplements Q&A). FDA approval applies to drugs, not to supplements like this one.
How much does Protoflow cost?
Two bottles are $158 ($79 each), three are $177 ($59 each) and six are $294 ($49 each), with free US shipping on three or six. At 2 capsules a day that works out to about $2.63, $1.97 or $1.63 a day.
Where can I buy Protoflow, and is it on Amazon?
Order Protoflow from this site, a USA authorized retailer, through the order button to secure checkout. No authorized Amazon or store listing is known. Two bottles are $79 each, three are $59 and six are $49, and every pack has a 60-day guarantee.
Is Protoflow legit, and is this the official website?
Protoflow is a real capsule supplement with a full 14-line Supplement Facts label, distributed by PhytoThrive Labs. This website is run by a USA authorized Protoflow retailer, and orders go through secure checkout with a 60-day money-back guarantee.
What is the Protoflow refund policy?
The sales page offers a 100% money-back guarantee for 60 days after you receive the bottles. Call the desk with your order ID, then mail the bottles back with tracking. Return shipping is on you, and refunds post 3 to 5 business days after the bottles are credited.
Can I take Protoflow with tamsulosin or finasteride?
We found no documented interaction with the label ingredients, but ask your doctor or pharmacist first and keep taking the prescribed medicine (MedlinePlus, Tamsulosin). Finasteride lowers PSA, so tell your urologist about every supplement you take.
Can you take Protoflow with Eliquis or warfarin?
Ask your prescriber first. Ginkgo may raise bleeding risk with blood thinners (NCCIH, Ginkgo), ginseng's effect on warfarin is mixed (MSK, Ginseng (Asian)), and vitamin E can add to bleeding (NIH ODS, Vitamin E). Keep taking your blood thinner exactly as prescribed.
Is shipping free on Protoflow orders?
The 3-bottle pack at $177 and the 6-bottle pack at $294 ship free in the US, and both list 4 bonus ebooks. The 2-bottle pack costs $158. Check the checkout page for the current terms before you pay.
Is Protoflow vegan, and what is the capsule made of?
No. The other-ingredients line lists gelatin, so the capsule shell is not vegan or vegetarian. Soy protein concentrate is also listed there, so anyone with a soy allergy should ask a doctor first.
