Beauty and skin health supplements including collagen, biotin, and antioxidant formulas.

Vital Proteins
Oral collagen studies generally show modest improvements in skin elasticity and hydration after around 8-12 weeks of consistent daily use — a slower, more gradual effect than topical actives.
NeoCell
Type 1 and 3 collagen specifically are the types most studied for skin — worth checking the label, since not all collagen supplements specify which type they contain.
Sports Research
Biotin supplementation mainly helps people who are actually deficient — most people eating a varied diet already get sufficient biotin and won't see dramatic hair or nail changes from supplementing further.
Nutrafol
One of the more clinically studied hair supplements on the market, with published data specifically on its Synergen Complex for hormonally-linked thinning.
Nordic Naturals
Omega-3 fatty acids (EPA and DHA) support the skin's lipid barrier from the inside, complementing topical barrier-repair ingredients rather than replacing them.
Hum Nutrition
Combines folic acid, zinc, and B12 — nutrients genuinely linked to hair growth cycles when someone is deficient in them specifically.
Moon Juice
Adaptogens like ashwagandha are studied for moderating cortisol response — relevant to skin since chronic stress hormones are linked to increased breakouts in some people.
Reserveage
Capsule format requires taking more units to match the collagen dose found in a single powder scoop — worth comparing per-serving amounts rather than just price.
Olly
Combines several hair-supporting nutrients into one softgel — convenient, though it also means you can't isolate which specific ingredient is responsible for any change you notice.
The Beauty Chef
Built around the gut-skin axis — a genuine area of ongoing research linking gut bacteria diversity to inflammatory skin conditions like acne and eczema.
Andrew Lessman
Vitamin D deficiency is genuinely linked to barrier dysfunction and conditions like eczema and psoriasis — worth discussing blood levels with a doctor before supplementing.
Physician's Choice
Specific probiotic strains, particularly Lactobacillus rhamnosus GG, have peer-reviewed data connecting gut flora to reduced acne severity in some studies.
Perricone MD
Based on Dr. Perricone's anti-inflammatory diet framework — the underlying idea that chronic inflammation accelerates visible skin aging has real support in dermatology research.
Garden of Life
Whole-food vitamin C sources include additional plant compounds beyond ascorbic acid alone, though the core vitamin C absorption is broadly comparable to standard supplements.
TULA
An oral probiotic aimed at the same gut-skin connection as topical probiotic skincare — the two approaches work through different pathways (internal vs. surface) rather than duplicating each other.
New Chapter
Uses whole fish oil rather than isolated, purified omega-3s — proponents argue the accompanying co-factors aid absorption, though purified versions offer more precise dosing.
SugarBearHair
A heavily celebrity-marketed hair gummy — worth checking the actual nutrient panel against the marketing, since the underlying ingredients are broadly similar to other biotin-based hair supplements.
Dose & Co
Designed to dissolve into hot coffee — collagen peptides are generally considered heat-stable, so brewing temperature shouldn't meaningfully reduce their structure or benefit.
