HelloPharmacist Scorecard of Biotin 5 by LifeLink

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Biotin 5 contains one active ingredient: biotin, a B vitamin that supports hair, skin, and nail health, and is used to address biotin deficiency. The tablet also includes inactive ingredients — dicalcium phosphate, croscarmelose sodium, stearic acid, magnesium stearate, and cellulose — which are fillers and binders that hold the tablet together.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Biotin's overall clinical evidence instead.

Strong

Strong clinical evidence supports Biotin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Biotin deficiency — rated "Likely Effective" (Natural Medicines).

Biotin is likely effective for treating biotin deficiency. For other uses — multiple sclerosis, seborrheic dermatitis (a type of scalp inflammation), and alopecia areata (patchy hair loss) — the evidence is either insufficient to rate it or suggests it may not be effective.

If you're taking this for hair, skin, or nail health in the absence of a deficiency, talk with your doctor about whether the evidence supports it for your goal.

The evidence, ingredient by ingredient Biotin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Biotin is generally well tolerated, even at fairly high doses, because your body excretes excess amounts in the urine. High-dose biotin has rarely been linked to mild diarrhea; one case reported transient mild diarrhea in patients taking 300 mg daily.

There is one isolated case report of a serious reaction (eosinophilic pleuropericarditis) in a woman taking biotin 10 mg plus other supplements and medications for 2 months, but whether biotin caused it remains unclear, and no similar cases have been reported since. Biotin from food and prenatal vitamins is considered likely safe in pregnancy and lactation, but check with your doctor before taking high-dose supplements during pregnancy or while breastfeeding.

  • None of the 1 matched ingredient has a documented medication interaction on file.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.

Biotin 5 is a straightforward B vitamin supplement with no documented drug interactions and good tolerability at normal doses. It's likely effective if you have a biotin deficiency; for hair, skin, and nail concerns without a known deficiency, the evidence is limited or weak.

If you're pregnant, breastfeeding, or taking high-dose biotin, discuss it with your doctor to make sure it fits your situation.

Biotin 5 by LifeLink: Common Questions

Does Biotin 5 by LifeLink interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Biotin 5. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Biotin 5 contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will biotin help my hair, skin, or nails?
Biotin is likely effective if you actually have a biotin deficiency — a rare condition. For hair, skin, and nail health in people without a deficiency, the evidence isn't strong enough to rate. If that's why you're interested, ask your doctor whether testing for a deficiency makes sense for you.
Is it safe to take biotin at this dose long-term?
Yes, biotin is generally well tolerated even at fairly high doses because your body excretes excess through the urine. High-dose biotin has rarely caused mild diarrhea. If you're pregnant, breastfeeding, or considering a very high dose, mention it to your doctor first.
Can I take this if I'm pregnant or breastfeeding?
Biotin from food and prenatal vitamins is considered likely safe during pregnancy and lactation. Before taking a high-dose supplement like this one, talk with your doctor to confirm it's right for you.
What's in this tablet besides biotin?
The tablet contains inactive ingredients — dicalcium phosphate, croscarmelose sodium, stearic acid, magnesium stearate, and cellulose — that act as fillers and binders to hold the tablet together.
Does biotin interact with any of my medications?
No interactions are documented in our data for biotin. That said, it's always smart to run your exact medication list through the interaction checker on this page, or ask your pharmacist to double-check.
