The Research
A meta-analysis of 26 randomized controlled trials found that hydrolysed collagen may help with skin elasticity and skin hydration at various doses from 1 to 12g per day. However, the effect for bovine collagen was not significant. To our knowledge, there is currently no clinical evidence that collagen supplements improve any aspect of gut health.
A meta-analysis of 47 studies (randomized and non-randomized) found that glycine supplementation may be helpful for sleep and metabolic health at various doses from 6 to 15g per day. However, the dose in this product is less. To our knowledge, there is currently no clinical evidence that glycine supplementation improves gut health.
A meta-analysis of 50 randomized, controlled trials showed that chicory-derived inulin-type fructans at a dose 3-20g per day may increase levels of beneficial Bifido-bacteria in healthy adults. However, the dose of chicory-derived inulin-type fructans in this product is less than 1g per serve.
