A recent scientific trial showed that glucosamine supplements, commonly used for treating osteoarthritis, can also promote intestine function.
Glucosamine is a poorly absorbed compound naturally occurring in cartilage that can improve joint health and decrease mortality rates when used as a supplement.
The randomized crossover trial, published in the journal Nutrients, demonstrates the effects of glucosamine intake on adults. The study involved healthy men and women who took 3 g of glucosamine hydrochloride every day for three weeks.
Results showed that glucosamine doesn’t stimulate bifidobacteria the way classic prebiotic fibers do. Interestingly, they substantially lower Pseudomonadaceae, Peptococcaceae, and Bacillaceae proportions in the gut microbiome, unlike prebiotics.
Additionally, glucosamine supplementation can significantly change the overall excretion of amino acids. In this case, it considerably decreased the amount of individual, total, and total-branched chain amino acids. What’s more, there were also no glucosamine traces in the fecal samples. Fecal short-chain fatty acids weren’t affected by glucosamine consumption.
Researchers also found that taking glucosamine supplements led to improvements related to bloating, constipation, and firm stools.
Finally, the joint health supplements market worth $2 billion could change due to the increased variety in supplemental products aimed at joint health. Turmeric (curcumin) and collagen are currently competing with glucosamine and chondroitin for the market share. Now that glucosamine has demonstrated effects beyond joint health, its place in the supplements market may only continue to rise.
