Biotin
Biotin is a member of the B-vitamin family — you will often see it labelled vitamin B7. Like its B-complex relatives, it is water-soluble, which means the body does not store large reserves of it and looks to a steady daily intake instead. In the supplement world, though, biotin has stepped a little into the spotlight on its own, thanks to its reputation as a beauty-from-within staple.

At the everyday level, biotin helps the body metabolize carbohydrates, fats and proteins — in other words, it plays a part in turning the food you eat into usable energy. That metabolic role is the workhorse side of the vitamin, quietly supporting the same processes as the rest of the B-complex family. It is the kind of behind-the-scenes job that makes biotin a natural fit within a broader B-vitamin routine.
The reason biotin gets its own shelf space, of course, is its second reputation: it helps maintain healthy hair, skin and nails. That trio is exactly why so many shoppers seek it out. People growing out their hair, tending to their nails or simply building a beauty-focused routine reach for biotin first, and it has become one of the most recognizable names in the hair, skin and nails category.
One practical tip before you buy: biotin strengths vary widely from product to product, far more than with many other vitamins. Rather than assume two bottles are equivalent, it is worth reading the label to see exactly what each serving delivers. Choosing a strength that suits your routine is simply a matter of comparing the panels side by side.
Biotin is one of the more format-flexible vitamins we stock. You will find it in capsules for a classic daily serving, gummies for anyone who prefers a chewable option, and liquid drops for easy, adjustable servings. It is also frequently combined with collagen or silica in beauty formulas, so you will often see it as part of a hair, skin and nails blend rather than on its own. As with any supplement, speak with your health-care practitioner before adding it to your routine.
