What is Biotin?
Biotin (vitamin B₇) is a water-soluble B-vitamin that helps convert dietary proteins, fats, and carbohydrates into the energy your cells need, and it’s especially prized for its role in maintaining healthy hair, skin, and nails.
Most biotin supplements also include nutrients that work synergistically with biotin: vitamin A to support healthy skin cell renewal; vitamin C for its antioxidant protection and its role in collagen synthesis; choline for cell-membrane structure and signaling; and more.
Biotin May Help With:
What To Look For In A Biotin Supplement
Aim for at least 5,000 mcg (5 mg) of biotin per serving—and make sure that amount refers solely to biotin itself, not to the combined weight of other ingredients or fillers. Some brands dilute their formulas with inexpensive bulking agents, so always check that the label specifies the biotin content clearly.
Choose a product manufactured in the United States under FDA-registered GMP facilities, where quality controls are stringent. In addition, look for verification seals from independent laboratories (e.g., USP, NSF, or ConsumerLab) to confirm potency and purity.
Select a supplement whose label lists every active and inactive ingredient, complete with exact amounts. Full disclosure helps you avoid unwanted additives and lets you compare formulas side by side.
Even the best supplement won’t work for everyone. Opt for brands offering at least a 60-day, 100% money-back guarantee so you can evaluate results risk-free. Steer clear of companies with opaque or restrictive return procedures.
What To Avoid
Avoid formulas loaded with artificial colors, flavors, or common bulking agents like magnesium stearate and silicon dioxide. These can dilute potency and, in sensitive individuals, cause digestive upset.
Be wary of any supplement that claims to “cure” hair loss, reverse skin aging, or treat medical conditions. Biotin supports normal hair, skin, and nail health—but it’s not a pharmaceutical treatment.
An ultra-low price tag often signals compromises in ingredient quality, sourcing, or testing. If the label omits ingredient amounts or is otherwise vague, it’s wiser to invest in a well-documented, transparently priced formula.
