From what I gather, most of this stuff does nothing in real life and you should just eat good food and exercise. Want fish oil, eat fish, need vitamin D, get some sun and eat stuff with vitamin D and so on. On the other hand, we are all lazy as eff so we don't do that. It also changes like every day as to whether any of the normal ones do anything at all. People have been going back and forth on fish oil supplements for like ever. I'm lucky and don't have to take any medications. I'm glad, because I would be terrible at it. I feel so bad for people that have to pay a crap ton of money and take a bunch of stuff every day.
If I take anything at all, it is basically the following:
Costco Organic Food Based Multi - I try and take food based vitamins if any because that makes sense to me, but i'm an idiot.
Whey Protein chowder after getting huge at the gym
Fish Oil, rarely and should prob take more based on some current stuff I've been reading which will probably change in 4 days
Vitamin D in winter because around December 3rd I start wanting to punch everyone in their stupid faces because its cold and dark outside. I don't think this does anything, but see below.
Random probiotics, I also try and drink kombucha on the regular.
If taking a choke yourself full of rock minerals every day makes you feel better, it probably isn't hurting you so do you.
