Biotin + Fenofibrate
Fenofibrate brand names: Tricor, Fenofibrate, Lipidil Micro, Lipidil Supra, Antara, and others.
We found no known interaction between Biotin and Fenofibrate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Biotin and Fenofibrate
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Fenofibrate and Biotin in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Biotin at all — not against Fenofibrate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Biotin safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Biotin in Pregnancy & Breastfeeding
When used orally and appropriately. Biotin has been safely used at the adequate intake (AI) dose of 30 mcg daily during pregnancy and 35 mcg daily during lactation. It has also been used in supplemental doses of up to 300 mcg daily. A tolerable upper intake level (UL) has not been established.

What Fenofibrate Is Prescribed For, and What Biotin Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Fenofibrate is a prescription medicine with approved uses on its FDA label. Biotin is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Fenofibrate is prescribed for: Fenofibrate is used alongside a cholesterol-lowering diet in adults to improve abnormal lipid levels. Tricor (tablet) and fenofibrate tablets are indicated to lower LDL cholesterol (bad cholesterol), total cholesterol, triglycerides, and apolipoprotein B, and to raise HDL cholesterol (good cholesterol) in adults with primary hypercholesterolemia (high cholesterol) or mixed dyslipidemia (mixed abnormal lipid levels). They are also used to treat severe hypertriglyceridemia (very high triglycerides). Antara and Lipofen (capsules) are indicated to reduce triglyceride levels in adults with severe hypertriglyceridemia, and to lower LDL cholesterol in adults with primary hyperlipidemia when other recommended LDL-lowering therapies cannot be used.

Fenofibrate has not been shown to reduce heart attacks or cardiovascular deaths in patients with type 2 diabetes.

Diabetes studied, not established Biotin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Biotin for diabetes
It is unclear if oral biotin is beneficial for type 2 diabetes.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Fenofibrate on your own; if you are taking Biotin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Fenofibrate page
“Fenofibrate (Tricor, Antara) is a cholesterol and triglyceride medicine that can strain the liver on its own, so this list of 59 supplements deserves genuine care rather than a shrug. Most of it, 38 ingredients, involves herbs that also stress the liver, ashwagandha among them, and stacking those effects is the risk that matters most h…”

About Biotin
What is Biotin?
- Hair growth and thinning hair
- Brittle nails
- Skin health
- Biotin deficiency
- Supporting metabolism
Biotin (vitamin B7) is a water-soluble vitamin your body needs to turn food into energy and to support healthy hair, skin, and nails. Most people get plenty from a normal diet, and true deficiency is rare. Supplements are widely sold for hair and nail health, but solid evidence for these benefits is limited in people who are not deficient, and high doses can interfere with certain lab tests.
Capsules, tablets, gummies, softgels, and as part of multivitamins or B-complex supplements
An interaction check asks whether these two react with each other — it does not ask whether Biotin is a good idea for someone in your situation. Here is what our Biotin record says about it on its own.
Biotin: dosing
There is no single standardized supplement dose proven to grow hair or strengthen nails. The amount your body needs each day is small and is usually met through a normal diet, so most people do not need a separate biotin supplement.Many over-the-counter products contain amounts that are far higher than the body's daily needs. If you have lab work scheduled, mention that you take biotin.
