yousowould recently posted that “pretty much all supplements are a load of shit” and if you read into it, he actually means they’re full of shit only if you are trying to increase testosterone and muscle mass.
Unless you aren’t getting those vitamins in your diet already, you don’t really need those “testosterone boosters.” He touts just fish oil, Vitamin D3 and creatine for evidence as to their efficacy and use as nutritional supplements which yield strong results, and he’s right, they do. There’s plenty of evidence to back them up.
My only qualm is with his choice of rhetoric that implies that “supplements are pretty much useless.” Perhaps for testosterone and muscle building, yes, as he’s posted links to evidence backing this up: many supplements have only a minor effect at best. But whether supplements as a whole are useful or not depends on your goals. Supplements can be used for more than just muscle-building and testosterone.
And what of supplements for nutrition?
Evidence shows that deficiency of particular nutrients or minerals leads to lower testosterone. For example, Magnesium is a big one for many people, and it has a minor effect on testosterone. Assuming that you already have The Perfect Diet™, you will receive diminishing returns on the benefits of your supplement if your food already gives you what your body needs. This is where a supplement will be pointless.
As for herbal supplements, they need more investigation as many have not been proven to have any marked effect on testosterone.
My point still stands: if you can’t get it in your food, take a supplement. Otherwise, if it’s redundant or there is no evidence for its purported effects, don’t bother. This point has already been made over on Return of Kings as to the definition of “supplement” – Something which completes or makes an addition. They won’t cure cancer and they won’t magically turn you into a swole beast, but supplements can help close the gap.
