Collagen Research
Skin Hydration & Elasticity
Research into smoother & hydrated skin
A 2023 review analysed 26 randomised controlled trials involving 1,721 participants to investigate how daily hydrolysed collagen supplementation affects skin hydration and elasticity. Researchers found statistically significant improvements in both measures compared with placebo, suggesting collagen may help skin retain moisture and improve its ability to stretch and return to its original shape.
A separate 2025 review of 10 clinical trials involving 646 participants also reported improvements in skin hydration and elasticity. These studies generally used between 1 and 10 grams of collagen daily. Together, the reviews offer encouraging evidence for oral collagen,
Amla & Skin Health
Botanical research into skin moisture and elasticity
A 2019 randomised, double-blind, placebo-controlled trial involving 99 women investigated a drink containing amla and lingonberry extracts over 12 weeks. Participants received either a lower-dose extract drink, a drink containing twice that amount, or a placebo. Researchers reported improvements in skin moisture, elasticity and thickness, alongside improvements in wrinkles around the eyes. The findings showed a dose-dependent response, with greater improvements associated with the higher-dose combination.
Fine Lines & Skin Appearance
Research into visible signs of skin ageing
A 2021 review analysed 19 clinical studies involving 1,125 participants aged between 20 and 70 to investigate the effects of hydrolysed collagen on skin ageing. Researchers reported improvements in wrinkles, skin hydration and elasticity compared with placebo. The authors concluded that taking collagen for approximately 90 days could improve these measured signs of skin ageing, suggesting potential benefits for smoother, more supple-looking skin.
A 2023 review examined 14 studies involving 967 participants to assess how oral hydrolysed collagen affected skin moisture, elasticity and other measures of skin ageing. The combined analysis found improvements in hydration and elasticity, indicating that collagen supplementation may help skin retain moisture and maintain its flexibility.
Collagen Research Overview
A broader review of skin and musculoskeletal outcomes
A 2026 umbrella review brought together 16 systematic reviews covering 113 randomised controlled trials and 7,983 participants to examine the effects of collagen supplementation across several areas of health. Rather than testing one supplement, researchers assessed findings from existing studies using different collagen formulations, doses and treatment periods.
The analysis reported improvements in skin hydration and elasticity, suggesting potential benefits for skin moisture and suppleness. It also found favourable results for selected musculoskeletal outcomes, including reduced joint pain and stiffness in people with osteoarthritis, and modest improvements in certain measures of muscle strength and body composition
Amla & Hair Growth
Amla and female hair growth: a 12-week clinical study
A randomised, placebo-controlled trial published in the Journal of Ethnopharmacology in 2024 investigated an oral preparation containing amla fruit (Phyllanthus emblica) in 60 women with female pattern hair loss. The study ran for 12 weeks and assessed whether the preparation influenced measurements associated with the hair growth cycle.
Researchers reported improvements in hair growth-cycle measurements compared with placebo, providing preliminary human evidence for the particular amla preparation studied.
Bamboo & Beauty Research
Bamboo-derived silica and biotin: research into hair, skin and nails
A randomised, double-blind, placebo-controlled clinical study published in Cureus in 2025 enrolled 105 participants, with 97 completing the 90-day study. Researchers compared a placebo with plant-derived biotin alone and a combination of plant-derived biotin and bamboo-derived silica.
The study reported improvements in several measurements relating to hair, skin and nails in the active treatment groups
