Keratin Hair
Overview
Keratin Hair is a multi-nutrient beauty formula built around hydrolysed keratin, targeted amino acids, and selected vitamins and minerals. The overall aim is to support normal hair, skin, and nail structure through nutritional building blocks and co-factors. It combines protein-derived components with trace minerals and B-vitamins commonly used in appearance-focused supplements.
Hair, skin & nails focus
Hydrolysed keratin is included as a structural protein component used in hair and nail formulations. Biotin and zinc contribute to normal hair and skin maintenance, while selenium supports normal hair and nail maintenance. Copper is included as a trace mineral involved in normal pigmentation-related processes.
Sulfur amino acids as building blocks
L-methionine and L-cystine are sulfur-containing amino acids often used to complement keratin-based formulas. They are included to provide additional amino acid support alongside the keratin source. This combination is designed to align with the natural amino-acid profile associated with keratin-rich tissues.
Botanical and silica-containing extract
Nettle (Urtica dioica L.) leaf extract is provided as a dry extract (10:1) with a specified silica content. It adds a plant-based element to the formula that is frequently used in beauty and hair-support blends. The extract complements the nutrient base without changing the product’s core nutritional approach.
Antioxidant and connective-tissue support
Vitamin C contributes to normal collagen formation for the normal function of skin and supports normal energy-yielding metabolism. Vitamin E, selenium, zinc, and copper contribute to the protection of cells from oxidative stress. These nutrients provide supportive coverage alongside the primary hair/skin/nails positioning.
Micronutrient balance and formulation notes
The formula includes iron (as bisglycinate), B-vitamins (B3, B5, B6, B9), and trace minerals to round out daily intake. Chelated and citrate mineral forms are used for practical supplement formulation and typical absorption characteristics. Excipients are limited to rice flour as a carrier, magnesium salts of fatty acids as an anti-caking agent, and a vegetable capsule shell.

Vorteile
Hair, Skin & Nails
Designed for people looking to support the normal structure and appearance of hair, skin, and nails with a keratin- and micronutrient-based formula. Hydrolysed keratin provides structural amino acids, while biotin, zinc, selenium, and copper contribute to normal keratin formation and pigmentation-related processes. Nettle extract adds a botanical component traditionally used in beauty-focused supplements.
Hair
Suitable for periods when hair quality is a priority, such as seasonal changes or after styling stress, by providing building blocks and supportive micronutrients. Hydrolysed keratin is paired with sulfur amino acids (L-methionine and L-cystine) that are commonly used in hair-focused formulations. Vitamin C and vitamin E complement the formula by supporting normal collagen formation and helping protect cells from oxidative stress.
Skin Health
Can be used as part of a daily beauty routine to support normal skin structure and antioxidant balance. Vitamin C contributes to normal collagen formation for skin function, while vitamin E, zinc, and selenium support protection of cells from oxidative stress. Nettle extract (10:1, with silica specified) adds a plant-derived component often included in skin and beauty blends.
Antioxidant Support
Useful for general lifestyle support when oxidative stress may be higher (e.g., busy schedules, environmental exposure), without implying any medical outcome. Vitamin E, vitamin C, selenium, zinc, and copper are included as nutrients that contribute to antioxidant-related physiological functions. This benefit is supportive within the broader beauty-focused positioning of the formula.
Energy Metabolism
May fit routines where users want nutritional coverage that also includes B-vitamins involved in normal energy-yielding metabolism. Niacin (B3), pantothenic acid (B5), vitamin B6, and folate (B9) are included at standard supplemental amounts. This is a peripheral benefit compared with the primary hair/skin/nails focus.
