Hair, Skin & Nails
Beauty-from-within is the idea behind this shelf — supplements built around nutrients that hair, skin and nails rely on. BioSil anchors the selection with its choline-stabilized silicon formula, available in several capsule counts as well as a mini vegan liquid capsule, while Naka Platinum's Biotin+ Beauty covers the classic biotin route. These products work from the inside out, complementing whatever creams, oils or hair masks you already use on the outside.

BioSil is the name most shoppers ask for. Its formula pairs silicon with choline, and the label's claim to fame is supporting the body's own collagen production — collagen being a structural protein in skin, while keratin does the same job in hair and nails. It comes in 46-, 90- and 120-count veggie capsule formats, and the Mini Vegan Liquid Capsules (60s and 120s) offer a smaller, easier-to-swallow option with vegan-friendly labelling from the manufacturer.
Biotin is the other pillar. Naka Platinum's Biotin+ Beauty delivers this B vitamin — which helps maintain healthy hair, skin and nails — in a 75-count veggie capsule. Biotin has been a beauty-counter staple for years for a simple reason: it's a single, recognizable nutrient at an accessible price. Between the two approaches, biotin is the simple classic while silicon-based formulas take the collagen-support angle — and some shoppers happily use both.
Results in this category are measured in months, not days — hair and nails grow slowly, so consistency matters more than intensity. Check each label's NPN directions, note that vegan and vegetarian designations reflect the manufacturer's labelling, and set expectations accordingly. If you're pregnant, nursing or taking medication, run your pick past your health-care practitioner first — and if you'd like a second opinion at the shelf, the Greenbrook team is glad to help.
