Core Nutritionals | Hair Skin Nails | 150 Capsules

Core Nutritionals Hair, Skin, & Nails is not a trendy “beauty blend.” It is a fully disclosed, capsule-based nutricosmetic formula built around four real goals: improve skin hydration, support collagen and extracellular matrix integrity, defend against oxidative stress that accelerates visible aging, and provide foundational support for stronger hair and nails. That strategy matters, because most products in this category lean too heavily on biotin alone. Core instead uses biotin as a supporting player and builds the formula around trademarked ingredients and meaningful doses.

Biotin is included at 5,000mcg, which is above the commonly cited 2.5mg supplemental range. Biotin is an essential cofactor for carboxylase enzymes involved in fatty acid synthesis, gluconeogenesis, and amino acid metabolism, and it also influences gene regulation through histone biotinylation. It is popular in the category, but the honest formulation take is this: evidence for visible hair and nail benefits in healthy, non-deficient users is limited. Core still includes it at a robust dose, but does not rely on it alone.

MSM is dosed at 1,000mg. Mechanistically, MSM acts as an organosulfur donor and supports connective tissue biology while also modulating NF-kB-driven inflammation and supporting antioxidant defenses through Nrf2-related pathways. The strongest clinical range for joints is usually 1.5-3g daily, so 1g is below the most studied range, but still directionally useful in a beauty formula where sulfur donation and connective tissue support matter.

Astrion™ is here at the full studied 490mg dose. This patented Astragalus membranaceus and Centella asiatica complex is designed to stimulate dermal fibroblasts, increasing endogenous collagen and hyaluronic acid production while also supporting improvements in skin texture, elasticity, visible pores, and brightness. This is one of the true differentiators of the formula because it targets the skin matrix directly rather than just tossing in generic antioxidants.

Setria® L-Glutathione is included at 250mg, the entry point of the clinically supported range. Setria is the most validated oral glutathione form on the market, with human data showing that oral supplementation can raise glutathione status in blood and cells. Glutathione is the body’s central intracellular antioxidant, and in a skin-focused formula that matters because oxidative stress accelerates collagen breakdown, dullness, and environmental damage. Vitamin C at 100mg complements this by helping maintain redox cycling and supporting collagen synthesis.

Hyaluronic acid is generously dosed at 240mg as sodium hyaluronate. That is a serious oral skin hydration dose. Hyaluronic acid helps bind water within connective tissue and the skin matrix, which translates into better hydration, plumper-looking skin, and support for smoothness and elasticity over time.

Dermaval™ is included at its studied 50mg dose. This phytonutrient complex is designed to blunt elastase and collagenase activity, two enzymes that break down elastin and collagen. In simple terms, Astrion helps build more of the structure, while Dermaval helps protect what you already have.

Ceramosides™ rounds out the formula at the clinically used 30mg dose. These wheat-derived phytoceramides help restore the skin’s lipid barrier, reduce transepidermal water loss, and improve hydration and elasticity from within. They also have relevance for hair quality and shedding support, making them one of the smarter additions in a comprehensive beauty formula.

The synergy is the real story: MSM, vitamin C, and biotin provide baseline structural support; Astrion and hyaluronic acid help increase and hydrate the dermal matrix; Dermaval and Setria help defend that matrix from oxidative and enzymatic breakdown; Ceramosides strengthens the barrier that keeps moisture in. Core also deserves credit for full transparency: no proprietary blend, no hidden doses, and multiple trademarked actives at their real intended amounts. Expect little in the way of a “day 1” cosmetic change, but with consistent use over 2-4 weeks, most users should notice better skin hydration first, followed by improvements in softness, elasticity, nail resilience, and overall hair quality with longer use.
