Sharon,
You might want to look up silymarin a hepato-protective.
From last year:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10667129/
Margi, I also am not seeing much benefit with the glucosamin/chondroitin.
I found a 5-in-1 called Dr. Best 5-in-1 from AMZ (
https://www.amazon.com/Doctors-Best-Glucosamine-Chondroitin-Hyaluronic/dp/B006UDGRAS?ref_=ast_sto_dp) which has everything one would want.
After a month or two we thought we saw some improvement but not significant. He's still getting it daily, as my wife and I are also taking it. I also got some bulk glucosamine and added another 1000mg and that hasn't help much more either. The thing I like about that product is that although human dose is 5 tablets, its the Type II collagen that studies show as superior to Glucosamine, and Glucosamine + Chondroitan.
1 capsule give 200mg of T2 Collagen, which is far above the 40mg needed to train the immune systems to stop attacking cartilidge and joints.
For Boots the Chondro-Protect is relatively cheap, seems to work noticeably, and comes in a small vial and is a simple pin prick shot between the shoulder blades once a month or 5-6 weeks.
For humans, I swear fish oil does actually work. 8-10 years ago I'd been working from home for a while already and had gone from about 170-180 to 200, then 220 at the worst. Knees and back were giving me a lot more pain and I started taking Trader Joe's fish oil as I figured it was better than normal drug store. Just threw it into the mix of my daily regimen and forgot about it kind of. About a month later I was hurrying up the stairs and realized I wasn't feeling any pain, and I think it had been a little while since I had.
Thats the only change I made food/vitamin-supplement wise, and I kept on it for probably a year or longer before I ran out and just forgot to restock. By then I'd jumped on Keto for the first time and dropped 20# and that was apparently just enough that my joints/back didn't complain.
ConsumerLabs used to be free and had a great fish oil review with actual mercury testing, etc.
Now I can find this one, and the Amazon affordable looks good as its US made from Norwegian fished stock.
Oh yes, dosage. Any Fish Oil product that just mentions x mgs of fish oil is junk.
They should list EPA/DHA seperately per dose. EPA IIRC is for cardio and muscles, DHA is actually what most of our brains are simply chock full of.
I tried to take enough so that my EPA intake was 1000mg or greater, which was usually 3x Trader Joes.
Not safe if one is one blood thinners or at risk for bleeding/stroke, etc. Wouldn't hurt to ask your Dr.
