9

Hyaluronate Acid

Hyaluronic acid (HA) is a glycosaminoglycan naturally present in skin, joints, and eyes. It can hold 1,000x its weight in water, making it essential for tissue hydration. Oral supplementation (high molecular weight) reaches skin and joints; clinical evidence supports benefits for skin hydration, wrinkle reduction, and joint comfort.

L-Glutathione

Glutathione (GSH) is the body's master antioxidant, a tripeptide of cysteine, glutamic acid, and glycine. It is central to detoxification (Phase II conjugation), immune function, and cellular protection. Liposomal and reduced (GSH) forms have improved bioavailability over standard oral glutathione.

12

Proline

L-Proline is a non-essential amino acid uniquely structured with a cyclic side chain. It constitutes about 17% of collagen, making it critical for skin, joint, tendon, and arterial wall integrity. Along with hydroxyproline and glycine, it forms the repeating Gly-Pro-Hyp motif in collagen.

13

Silicon

Silicon is a trace mineral essential for connective tissue formation, bone mineralization, and collagen cross-linking. Orthosilicic acid is the bioavailable form. The Framingham Offspring Study found silicon intake was positively associated with bone mineral density, stronger than calcium in some analyses.

Stacking Tips

The beauty supplement stack is Collagen (10g) + Vitamin C (500mg) + Biotin (2500mcg). Vitamin C is essential for collagen synthesis — without it, supplemental collagen is less effective. Take collagen on an empty stomach for best absorption.

For skin hydration specifically, add Hyaluronic Acid (120mg) and Omega-3 (2g) — these work from the inside out to improve skin moisture and reduce inflammation-related skin aging.

For hair growth, combine Biotin + Zinc + Iron (if deficient). Hair loss is often driven by nutrient deficiencies — get blood work to check ferritin, zinc, and vitamin D levels before supplementing.

Tip: Results take time — expect 4-8 weeks for skin improvements, 3-6 months for hair and nail changes. Consistency is more important than dose.

Frequently asked

What is the best supplement for skin?

Collagen peptides (10-15g daily) have the most clinical evidence for improving skin health — elasticity, hydration, and wrinkle reduction. Always pair with Vitamin C (500mg) to support collagen synthesis. Hyaluronic acid (120mg) adds hydration from the inside out.

Does biotin really help hair growth?

Biotin is most effective for people with biotin deficiency, which is more common than previously thought. For those with adequate biotin levels, benefits are more modest. Clinical evidence is strongest for nail strength (25% improvement) and hair in deficiency states. 2500-5000mcg daily is the therapeutic range.

How long does collagen take to improve skin?

Most clinical trials show improvements in skin elasticity and hydration within 4-8 weeks at doses of 5-10g daily. Maximum benefits, including wrinkle reduction and improved firmness, typically appear at 8-12 weeks. Hair and nail improvements take 3-6 months.

Can supplements help with acne?

Yes. Zinc (30mg daily) has strong evidence for reducing acne severity. Omega-3s reduce inflammatory acne. Probiotics improve gut-skin axis. Vitamin A supports skin cell turnover. Avoid high-dose Biotin if acne-prone — it can worsen breakouts in some people.

What supplements prevent hair loss?

Address deficiencies first: Iron (ferritin should be above 40ng/mL), Vitamin D (above 40ng/mL), and Zinc. Biotin supports keratin production. Collagen provides amino acids for hair growth. Saw palmetto may help with androgenic hair loss by blocking DHT conversion.
