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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check in this product.
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.
