To people who put too much stock in these "studies", consider this: as of July 2020 we _still_ have no conclusive answer if _eggs_ are good for you or not. What makes you believe this is any different?
are there dietary sources of glucosamine?
Yes - cartilage. If you eat chicken or something like that, eat the cartilage. You can do this on pre-cooked chickens you get from Sam's Club / Costco. If you eat chicken breasts only (which a lot of health-conscious people do), you don't get this benefit. I talked to Dr.Yang Jwing Ming (one of the few Kung Fu practioners with a Western phd and he said eating cartilage is one of the best ways to help reduce the risk…
are there dietary sources of glucosamine?
there's no reason to believe macromolecules like glucosamine benefit the body any more than regular, nutritious food. ingested nutrition generally gets broken down into amino acids and the like in the digestive system before it gets distributed to the rest of the body to be reconsistuted into cells and tissue. cartilage in particular is scaffolding and generally must be constructed by other cells from very basic mole…
are there dietary sources of glucosamine?
It is important to remember the study only saw a correlation between the dietary supplement and mortality. Glucosamine Sulfate is from what I understand the most common form in the supplements on the shelf. Our bodies produce glucosamine naturally. > Specifically in humans, glucosamine-6-phosphate is synthesized from fructose 6-phosphate and glutamine by glutamine—fructose-6-phosphate transaminase as the first step o…
Always used this site when trying to find unbiased information, and also not be to hyped about a single study. However now the effect matrix is hidden behind a paywall.
When talking about joint health: As a young and very active person my biggest problem is overtraining injuries. Wish I knew how to be able to train as much as I would like to, with just a simple supplement or so...
I've been supplementing glucosamine along with a large amount of other things for awhile now. I'm not too bullish on it in humans, but it doesn't seem like it hurts, and is definitely cheap: https://nearcyan.com/supplements My latest favorites that I'm a bit more hopeful for are glycine, spermadine, and rapamycin.
I'm interested in it's benefits for autoimmune diseases but it seems quite expensive (in the US).

> Edit: Yea, reading the study, I don't see anything about controlling for fitness level. They specifically control for the following lifestyle factors: "smoking status, alcohol consumption, physical activity, body mass index (BMI) and vegetable and fruit consumption." (Ctrl+f for "covariates") In the conclusion, they acknowledge: "Although we had carefully adjusted for potential confounding lifestyle-related factors…
But if someone "works out heavily and supplements," that should show up in self reported physical activity, and indirectly in BMI. Well, not to nitpick, but people with high muscle mass can easily end up with an "obese" BMI even if they have very low body fat. And it also doesn't take very many hours of working out per week to get jacked if you're doing heavy weightlifting and supplementing. No idea if such people ar…
It's more an issue if there is something they haven't accounted for, as they point out.
I also give give them fish oil pills, but I've never been able to notice a difference.

Do you take each Vitamin individually, or do you take a multivitamin? Do you make an effort to get large doses of these things from food first?
Individually. Sometimes a few things are combined when a good option is available, but generally multivitamins don't give me what I want in the doses that I want. Since I tested all of my blood metrics beforehand, it's unlikely the market would have a 'perfect' vitamin for me. Especially since most of what I like to take isn't technically a vitamin. My diet is currently pretty un-optimized, so although I would prefer…
Daily intake of, tomato juice, kefir, sardines, salmon, spinach, sunflower seeds, pumpkin seeds, pistachio, eggs. You could probably get a whole days worth of food into a snack, a salad, and a soup.
