Another hyped-up supplement shown not to work in a study: d-Aspartic Acid

[Nelson Vergel]

In a recently published placebo controlled study, D-ASP supplementation was found to be ineffective in up-regulating the activity of the hypothalamo-pituitary-gonadal axis and to have no anabolic or ergogenic effects in skeletal muscle.

However, d-Aspartic Acid was shown to work in a previous study (not placebo controlled) in Italy: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2774316/

Almost every supplement out there has contradictory data. This one is no different. It is very difficult to trust data when several studies show different and contradictory results. However, most research labs studying supplements do not have the large budgets that pharma has, so studies tend to be smaller and not as well controlled. Very few supplement studies are funded by the National Institute of Health in the US.

Since the FDA does not regulate supplements, most companies can make any claim as long as they say (usually in tiny words on the label): "This statement has not been reviewed by the FDA".

I have taken it a few times in the past, out of curiosity I did BW one time, I did nothing for my tt and cut my ft in half, I know another person that had the same result as me, some people say it will help older guys with low test levels, I say bs, at the time I tested it I was 45 with crappy levels, tt 200, ft 4.0, after BW tt still approx. 200, ft 2.0

This is not correct, supplements are not allowed to make claims that they can treat illness, even when such claims are supported by studies.
