Great post!
So yes I do not take supplements mainly bc I’m noncomplaint with the ones that work and there’s far too many that are wasteful.
BCAAs are pretty much pointless if you are eating most of your protein from animal products. Most of the claims to them are based on acute studies looking at blood amino acid levels after a single bout of exercise. However, changes in these acute variables are not predictive of chronic changes in body composition or performance. So you train once, take whey post workout, and you have more circulating leucine or an increase in fractional synthetic rates. So does this mean that this will happen after 36 workouts? 48? 64? Does this mean that muscle mass will increase? The answer is we don’t know because we’d have to take measurements after every workout for the duration of a training program to really find out.
Is that necessary when we know that if we eat enough protein and train progressively we’ll get bigger and stronger? No right or wrong answer here but that’s my $0.02 on leucine/bcaas tsken exogenously.
As far as fish oil and multi vitamins I’m all for it them you aren’t getting them from your diet. However, certain vitamins, such as b12 should be taken separate from a multi because other nutrients will take priority in terms of absorption. Same with magnesium, always wanna take it separate from calcium. Ultimately you still need to get your micronutrients and if you aren’t getting them all from food, then a supplement isn’t the worst thing in the world.
