Key Facts

Biotin is a B-vitamin that acts as a cofactor for enzymes involved in metabolizing fats, carbohydrates, and amino acids
Supports hair, skin, and nail health, plus glucose metabolism
Particularly useful for people on antibiotics, anti-seizure medications, or with digestive conditions that impair nutrient absorption

Ingredients

Biotin (as d-biotin).

Why We Chose This

Biotin deficiency is uncommon in healthy people but becomes relevant when gut bacteria are disrupted by antibiotics, when certain medications interfere with synthesis, or when digestive conditions limit nutrient absorption. Signs like brittle nails, dry skin, and hair loss can signal low biotin levels. This formulation provides straightforward biotin supplementation for those with specific risk factors or documented deficiency. One important note: biotin can interfere with certain lab tests, so it's worth mentioning to your healthcare provider before blood work.

Niacinamide

Niacinamide (vitamin B3) is a multitasking skin ingredient that strengthens the skin barrier, supports cellular repair and hydration, and helps regulate oil production. It may reduce acne and excess oil, calm redness and rosacea, fade dark spots, shrink enlarged pores, and improve fine lines for clearer, smoother, more even-looking skin.

Frequently Asked Questions About Biotin

What is the supporting research for the benefits of biotin?

Oral biotin appears to prevent or reverse symptoms in biotinidase deficiency. (NIH biotin fact sheet)
Untreated biotinidase deficiency leads to severe neurological complications. (biotinidase deficiency review)
Evidence for biotin in hair loss appears limited and largely anecdotal. (hair loss review)

How do I take biotin?

Take 1 capsule one to two times daily, or follow your healthcare practitioner's guidance for your specific needs.

Biotin works best when taken consistently, as it supports enzyme function across fat, carb, and amino acid metabolism throughout your body.

Can I take biotin with other supplements or medications?

Biotin may interact with certain medications, particularly antiseizure drugs, which can lower your biotin levels. Always discuss any supplements you're taking with your healthcare provider, as they can identify potential interactions and flag whether biotin might interfere with your lab tests.

Who might benefit from taking biotin?

Biotin supports those with digestive issues, antibiotic use, or seizure medications that compromise nutrient absorption and synthesis. It's also beneficial for anyone experiencing brittle nails, hair loss, or dry skin linked to low biotin levels.

How long does it typically take to notice effects of biotin?

Most people notice biotin's effects within a few weeks to six months of consistent use, though the timeline depends on what you're targeting. Hair and skin improvements typically take three to six months since they follow your body's natural growth cycles.
