Real trademarked ingredients, clear labels, solid help for moisture and skin strength.
Core Nutritionals Hair, Skin, & Nails isn't some fad beauty mix. It's a straight-up capsule formula with full disclosure, aimed at four big wins: better skin moisture, stronger collagen and tissue support, fighting off the oxidative stuff that ages you faster, and basics for healthier hair and nails. That's key because most products just dump in biotin and stop there. Core uses biotin as backup and builds around trademarked ingredients with solid doses.
Biotin is in at 5,000mcg, more than the usual 2.5mg add-on. It's a key helper for enzymes in fat making, energy from sugar, and protein breakdown, plus it tweaks genes via histone changes. People love it for this category, but let's be real: proof for big hair and nail perks in healthy folks without deficiency is iffy. Core still packs a strong dose but doesn't bet the farm on it.
MSM comes in at 1,000mg. It donates sulfur for tissues, calms inflammation via NF-kB paths, and boosts antioxidants through Nrf2. Top studies for joints use 1.5-3g a day, so 1g is under that but still helpful here where sulfur and tissue support count for beauty.
Astrion™ is at the full 490mg from studies. This patented mix of Astragalus membranaceus and Centella asiatica ramps up skin cells to make more collagen and hyaluronic acid on their own, helping texture, bounce, pores, and glow. That's a standout because it hits the skin foundation head-on instead of just tossing in biotin.
Core Hair Skin Nails by Core Nutritionals contains 100mg Vitamin C, a clinical dose for health and performance.
Key Highlights
- 490mg Astrion™ — that's the full dose from studies on NuLiv Science’s patented Astragalus and Centella mix. It gets your skin cells firing to pump out more collagen and hyaluronic acid, way smarter than just leaning on biotin.
- 250mg Setria® L-Glutathione — a dose that matters, from the top oral glutathione brand out there. Studies show it boosts your glutathione levels when taken by mouth, giving you inside-out protection against oxidative stress.
- 240mg Hyaluronic Acid — a real dose for hydration, not some tiny add-in. It grabs onto water in your tissues and skin, helping keep things moist, smooth, and feeling plump over time.
- 30mg Ceramosides™ — the dose used in studies, from wheat-based lipids. They beef up your skin barrier to cut down on water loss, great for dry, rough, or beat-up skin.
- 50mg Dermaval™ — at the researched amount to dial back elastase and collagenase after sugar spikes. Basically, it helps shield your collagen and elastin from getting chewed up.
- 1,000mg MSM — a decent dose for tissue support, adding sulfur for proteins while easing inflammation and antioxidants. It's under the 1.5-3g joint studies, but fits nice here for hair, skin, and nails.
- 5,000mcg Biotin — a solid hit of the go-to vitamin for this. Proof in healthy people is limited and Core owns that, but this ensures it's not holding back the full beauty setup.
- 100mg Vitamin C — ties in for collagen help and works with glutathione and MSM. It's key for making collagen right and keeping antioxidants in check with Setria®.

How to Use
Take 5 capsules daily with a meal and full water glass. Food helps swallow the serving and builds the habit, key for Ceramosides™, Astrion™, Setria®, and hyaluronic acid to shine over time. No need to split, but if big caps bug you, do 2 with one meal, 3 with another. Not workout-timed—no stims or quick boosters. Don't cycle; steady use beats breaks since perks build up. Stacks great with collagen, protein powder, fish oil, multis. If you're on extra biotin, check totals—it can mess some blood tests. Store cool and dry, lid tight to keep capsules fresh from heat and wet.
What to Expect
Not a quick-hit like energy supps, so timeline's longer. Days 1-7: just get in the habit, no big feels beyond easy capsules. Weeks 2-4: skin moisture often shows first from hyaluronic acid and Ceramosides™ helping hold water and barriers. Around then, nails might feel stronger, less splitty, thanks to MSM, biotin, vitamin C on structure. Weeks 4-8: smoother skin, better bounce, less dry, overall tougher tissues kick in. Setria® and Astrion™ do their antioxidant and matrix work quietly, showing as steady upgrades, not sudden rushes.

Frequently Asked Questions
How much biotin is in Core Nutritionals Hair, Skin, & Nails?
Each 5-capsule serving provides 5,000mcg of biotin as d-biotin. That is a high dose by category standards and well above the commonly cited 2.5mg supplemental range, although the strongest evidence for biotin remains in deficiency states rather than healthy users.
Is this just a biotin supplement with a fancy label?
No. Biotin is only one part of the formula. The real differentiators are Astrion™ at 490mg for endogenous collagen and hyaluronic acid support, Setria® glutathione at 250mg for antioxidant defense, hyaluronic acid at 240mg for hydration, Dermaval™ at 50mg for collagen/elastin protection, and Ceramosides™ at 30mg for skin barrier support.
How long does it take to notice results from this formula?
Most users should think in weeks, not hours or days. Skin hydration is often the earliest noticeable change within 2-4 weeks, while improvements in overall skin texture, nail resilience, and hair quality usually become clearer with longer consistent use.
What makes Setria® glutathione different from generic glutathione?
Setria® is the best-known clinically studied oral glutathione trademark. Human data has shown that it can raise glutathione status in blood and cells, which is important because glutathione is the body’s primary intracellular antioxidant and a key player in detoxification and oxidative stress control.
Why is Ceramosides™ important in a hair, skin, and nails formula?
Ceramosides™ provides wheat-derived phytoceramides that help rebuild the skin’s lipid barrier. That reduces transepidermal water loss and improves hydration and elasticity, making it especially valuable for users with dry, compromised, or environmentally stressed skin.
Can I take this with collagen peptides?
Yes, and that is one of the smartest ways to stack it. Astrion™ is designed to stimulate endogenous collagen and hyaluronic acid production, while collagen peptides provide additional structural amino acids and vitamin C in this formula supports collagen synthesis chemistry.
Does this product contain stimulants or caffeine?
No. Despite a metadata inconsistency, the verified active formula is stim-free and contains no caffeine. It can be taken any time of day based on convenience.
Are there any allergen concerns with this formula?
Yes. Ceramosides™ is derived from wheat seed extract, so anyone with a wheat allergy or strong sensitivity should avoid the product unless their healthcare professional says otherwise.
Should I stop taking this before bloodwork?
You should discuss that with your clinician, especially because the formula contains 5,000mcg of biotin. High-dose biotin can interfere with certain lab tests, including thyroid, hormone, and some cardiac markers.
How does this compare to typical hair, skin, and nails gummies?
Most gummies are limited by space and usually lean heavily on biotin with smaller support nutrients. This capsule format allows Core to include meaningful doses of MSM, hyaluronic acid, Setria®, Astrion™, Dermaval™, and Ceramosides™ in a way gummy formats usually cannot match.
