Keratin Hair Booster
Reserveage Nutrition
Overview
The supplement broadly aims to enhance hair and nail health, primarily leveraging Cynatine HNS keratin. While this patented keratin has demonstrated statistically significant results in improving hair growth and strength in clinical trials, the overall effectiveness of the blend is moderate due to some ingredients having indirect benefits or being part of proprietary blends with unknown concentrations.
The Good
Utilizes Cynatine HNS, a clinically-backed keratin shown to improve hair and nail strength and growth.
Provides a high, likely effective dose of Biotin for hair and nail health.
Includes essential minerals Zinc and Copper, crucial for connective tissue and hair follicle health.
The Bad
The 'Pro-Longevity Factors Blend' is a proprietary blend, making it difficult to ascertain the exact dose and efficacy of all its components, particularly Japanese Knotweed and grape extracts.
The dose of Trans-Resveratrol (20mg) is lower than typically observed in clinical trials showing significant metabolic benefits (often 150-500mg).
High Biotin dosage can lead to false results in certain medical lab tests.
