3 Supplements to NOT Take
by Sol Orwell
D-Aspartic Acid (aka DAA)
(DAA) enjoyed its rise to fame, and now it is time to come back to reality. DAA is a naturally occurring regulator of testosterone production, and when it is given to humans it can increase testosterone levels. That much is true, but practically speaking this doesn’t really mean anything (if I increase your car’s efficiency from 40 to 41 mpg, does it matter?)
The first study lasted a 12 days, which was odd as most studies are 28 days or more. This was the study that had everyone hyped up over its ability to boost testosterone (which even then was not much). More recent evidence shows that gradually after the 12-15 day point the testosterone boost started to decline. After 28 days testosterone is back normal, and there are some reports (nonscientific, but people testing their blood) that it would even go below baseline!
The only exception may be infertile men with very low testosterone (at which point you can get it prescribed by a doctor).
Rooibos is a tea that is touted as better than green tea due to its ‘strong’ antioxidant properties, a more pleasant taste, and the ability to rehydrate athletes as well!
The problem is that the only true thing above is that it tastes nice. Rooibos is quite a potent antioxidant when tested outside the body but most of the molecules in it are not well absorbed which prevents them from working well in humans (for those that know about how glutamine is useless, exact same situation!). Oddly, it would seem like Rooibos would at least beat out green tea when tested outside the body but green tea is still more potent.
The lone study actually looking at the hydration claim found it baseless and no better than water consumption.
L-Arginine is a pretty respectable amino acid, but that doesn’t mean it makes a good supplement. If you removed all of the arginine from your body you would indeed die, and increasing arginine in the blood does serve a role at times, usually for increasing oxygen delivery to muscles and increasing power output.
Too bad L-Arginine in your mouth doesn’t end up in your blood all that much, and when it does it doesn’t do what it is supposed to do. Beyond that, even if you look at one of its two problems (poor absorption) or it not doing what it is supposed to do (increase nitric oxide) you realize that arginine actually underperforms other supplements.
There is no reason to ever supplement L-Arginine over its related amino acid (L-Citrulline) which has better absorption but is equally effective, or over any other nitric oxide booster such as nitrates (from beetroot).
