๐‡๐ข๐ ๐ก ๐๐จ๐ญ๐ž๐ง๐œ๐ฒ: This product contains a high potency of Biotin Collagen Peptides and Vitamin D3 to support hair growth, healthy skin, strong nails and strong bones. Each serving of 1mL contains Biotin 10,000mcg, Collagen Peptides 50,000mcg and Vitamin D3 5,000 IU.

๐๐ข๐จ๐ญ๐ข๐ง: Biotin helps maintain many of your bodyโ€™s major systems. Like other B vitamins, Biotin helps your body use enzymes and carry nutrients throughout the body. Biotin is well known for its positive effects on hair. Research shows that it improves hair health - including shine, volume, and scalp coverage in women who experience thinning hair.

๐‚๐จ๐ฅ๐ฅ๐š๐ ๐ž๐ง ๐๐ž๐ฉ๐ญ๐ข๐๐ž๐ฌ: Collagen is a protein responsible for healthy joints and skin elasticity, or stretchiness. As you age, your existing collagen breaks down, and it gets harder for your body to produce more. Objective dermatological measurements, such as cutometry and corneometry, have proven that oral collagen peptides together with other dermonutrients significantly improve skin hydration, elasticity, roughness, and density after three months of intake.

๐•๐ข๐ญ๐š๐ฆ๐ข๐ง ๐ƒ3: What does vitamin D3 have to do with hair? Vitamin D is metabolized in the skin by keratinocytes. These are skin cells that process keratin, a protein in hair, nails, and skin. When the body doesnโ€™t have enough vitamin D, keratinocytes in hair follicles have trouble regulating hair growth and shedding. Research shows that in patients with alopecia areata, hair follicle cycling is disrupted due to low levels of vitamin D.

At the same time, collagen peptides contain many amino acids your body needs to make keratin. Vitamin D is metabolized in the skin by keratinocytes. These are skin cells that process keratin, a protein in hair, nails, and skin. New Elements liquid biotin collagen and vitamin D3 supplement, is the perfect combination for hair, nail, skin and bones health.
