Glucosamine supplements may lower risk of death just as much as regular exercise

It's been hypothesized that glucosamine creates a similar response as calorie restriction. This effect was observed in rats in 2020 [0].

The study is a mess. The article is more of a mess. Touting the benefits of glucosamine which has been pretty much debunked as a beneficial joint supplement. They used epidemiological data from as far back as 1999. They pretend they've been able to adjust for all other confounding factors. It reduced ALL other causes of mortality?

This is all nonsense. How did the guy decided to study this (oh he's in Family Medicine BTW not research or orthopedics)? He asked his biking buddies who uses Glucosamine (he does also) and they all said yes so he wondered if there was any reason?

Classifying this as science is a sham

I wonder if this applies to NAG (N-Acetyl-Glucosamine) as well - I've been taking it for years as it's a benign supplement against autoimmune diseases [0].
