Hair, Skin & Nails

The most evidence-backed supplements for hair, skin, and nail health are hyaluronic acid, vitamin C, and magnesium. Oral hyaluronic acid has been shown in randomised trials published in the Journal of Clinical and Aesthetic Dermatology to significantly improve skin hydration and reduce the appearance of fine lines after 8 to 12 weeks of daily supplementation. Vitamin C is essential for collagen synthesis, the structural protein that gives skin elasticity and nails strength. Magnesium bisglycinate supports keratin production, the protein that forms both hair shafts and nail plates, and deficiency is linked to hair thinning and brittle nails. Astragalus rounds out the collection with antioxidant compounds that protect cells from oxidative stress, one of the primary drivers of premature skin ageing.

Yes. Multiple peer-reviewed clinical trials support oral hyaluronic acid supplementation for skin health. A double-blind placebo-controlled study in the journal Nutrients found that participants taking 120mg of oral hyaluronic acid daily showed a 16% improvement in skin moisture levels and a significant reduction in skin roughness after 12 weeks compared to placebo. Unlike topical hyaluronic acid, which primarily hydrates the surface, oral supplementation increases hyaluronic acid levels within the dermis, the deeper structural layer of skin. Pairing hyaluronic acid with vitamin C, as in our 250mg and 50mg formula, enhances collagen synthesis simultaneously, addressing both hydration and skin structure in a single capsule.

Astragalus (Astragalus membranaceus) is a traditional adaptogenic herb that has attracted modern research interest for its anti-ageing and skin-protective properties. Its primary active compounds, astragalosides, have been shown in laboratory studies to activate telomerase, an enzyme that helps maintain telomere length in cells. Shorter telomeres are directly associated with faster cellular ageing and reduced skin regeneration capacity. Astragalus also contains potent polysaccharides and flavonoids that neutralise free radicals and support immune function, which plays a role in skin barrier integrity. At 2000mg per serving, our astragalus capsules deliver one of the higher doses available in capsule format for noticeable antioxidant and cellular protective effects.

Most clinical studies on oral supplements for hair, skin, and nails use trial periods of 8 to 12 weeks before measuring outcomes, and this reflects how long collagen turnover and keratin growth cycles take to show visible change. For skin hydration, hyaluronic acid supplementation can show measurable improvements in moisture levels within 4 to 6 weeks. Nail growth typically takes 6 to 8 weeks to reflect nutritional changes since nails grow approximately 3mm per month. Hair changes take the longest, usually 12 weeks or more, because the hair growth cycle moves through resting and active phases. Consistent daily supplementation is the most important factor. Inconsistent dosing resets the saturation process and delays results.
