i heard collagen was good for joints & skin. not 100% on that. its expensive af so not really buying it any longer.
also take Q10. heard your levels drop off as you get older.
use to take 50mg zinc but its way too much. i heard its best to take every 2 days. also needs to be balanced with Copper.
use to buy "Expensive" vitamins like Orange triad by Controlled labs... just ended up buying cheaper vitamins later on. maybe i'll return to bodybuilding vitamins later for joint support..idk.
i remember when taking orange triad while pounding food down. Digestion was amazing cause whatever i ate came out extra easy.
