Does Protoflow Contain Vitamin K or Biotin? The Label Answer
People who watch their vitamin K intake, or who need to know about biotin before a blood test, ask if Protoflow has either one. Here is what the label shows.
Quick answer
No. Protoflow has no vitamin K and no biotin on its label. The only two vitamins in the formula are vitamin E (13 mg) and niacin, vitamin B3 (75 mg). The other twelve rows are botanicals and inosine. Three rows do carry a bleeding caution, so talk to your pharmacist if you take a blood thinner.
Does Protoflow contain vitamin K?
No. Vitamin K is not on the Protoflow Supplement Facts panel. It is also not in the other ingredients line under the panel. A search for "Protoflow with no vit K" has a simple answer: the formula is free of vitamin K as an added ingredient.
Why do people ask? Vitamin K plays a part in normal blood clotting. Some people who take a blood-thinning medicine are told to keep their vitamin K intake steady from day to day. So they check every new product for it. That is a good habit, and it is the reason this post exists.
But "no vitamin K" is not the end of the check for Proto Flow. Some other rows on the label also relate to bleeding. We cover them below, because they matter more for that group of buyers than vitamin K does.
Is there any biotin in Protoflow?
No. Biotin, sometimes called vitamin B7, is not on the Protoflow label. The only B vitamin in the formula is niacin, which is vitamin B3.
People often ask about biotin because high doses of it can affect some lab blood tests. If your doctor has asked you to stop biotin before a test, Protoflow does not add any. Still, tell the lab or your doctor about every supplement you take. They can decide what matters for your test.
If you take a hair, skin or nail product with biotin, Protoflow does not double it up. The B vitamin to add up with Protoflow is niacin, not biotin.
The only two vitamins in Protoflow: E and niacin
| Vitamin | On the label? | Amount |
|---|---|---|
| Vitamin E (D-alpha tocopheryl succinate) | Yes | 13 mg, 87% DV |
| Niacin (vitamin B3) | Yes | 75 mg, 469% DV |
| Vitamin K | No | None listed |
| Biotin (vitamin B7) | No | None listed |
| Any other vitamin or mineral | No | None listed |
Vitamin E here is the natural form. Niacin at 75 mg is more than double the 35 mg adult upper limit for niacin from supplements. That can cause flushing: a warm, red, tingly feeling in the skin. If you take a multivitamin or a B-complex, add its niacin to the 75 mg before you start.
The other twelve rows are hawthorn, epimedium, damiana, muira puama, ginkgo, Chinese ginseng, tribulus, catuaba, saw palmetto, inosine, oat straw and cayenne. None of them is a vitamin. See the full Protoflow ingredients page for each amount.
Protoflow vitamin K and blood thinners: the rows that matter more
If you ask about vitamin K because you take a blood thinner, read this part twice. Three rows on the Protoflow label each carry a published caution about bleeding:
- Vitamin E, 13 mg. NIH notes that vitamin E can raise bleeding risk in people taking anticoagulant or antiplatelet medicines.
- Ginkgo biloba, 120 mg. NIH notes that ginkgo may raise bleeding risk in people taking anticoagulant drugs.
- Chinese ginseng, 120 mg. NIH notes that Asian ginseng may interfere with blood clotting.
So the absence of vitamin K does not make Protoflow a simple choice for this group. Three rows that touch the same topic sit in the same capsule. The label's own caution covers it: "If you are currently taking any medication, consult with a physician prior to use. Do not exceed suggested use."
Our longer post on Protoflow and blood thinners quotes each NIH line in full.
Can Protoflow affect your prescription medications?
No interaction study of the finished Protoflow formula is published. What exists are general notes on single ingredients, like the three above. That is why the label sends anyone on medication to a physician first.
A good way to have that talk is to bring the bottle, or a clear photo of the full panel, to your pharmacist. Ask three questions:
- Do any of these fourteen rows matter with my current medicines?
- Is 75 mg of niacin fine with what else I take?
- Should I check anything after I start?
Our list of questions to ask your doctor before Protoflow has more ideas.

Our view
Protoflow has no vitamin K and no biotin. Its two vitamins are vitamin E and niacin, and both amounts are printed on the label.
If you asked because of a blood thinner, the bleeding rows matter more than the vitamin K answer. Show the full panel to your pharmacist, and start only once they are happy with it.
