Testosterone Booster Reviews

D-Aspartic Acid Powder (By AI Sports Nutrition)

By  | 

D-Aspartic Acid Powder by AI Sports Nutrition “contains 3,000 mg of D-aspartic acid per scoop”.  According to AI Sports Nutrition, it’s very rare that a supplement comes along that “each dose is tailored to current amounts that are being used and studied”.

Maybe that’s stretching the truth a bit, I can think of at least 6 other supplements I’ve reviewed that contain exactly the same amount of DAA.


D-Aspartic Acid Powder by AI Sports Nutrition Nutrient Profile

D-Aspartic Acid (Sodium D-Aspartic Acid) (3,000 mg) operates in the central brain region and helps to regulate testosterone synthesis. A number of high profile studies appear to confirm that D-aspartic acid is a formidable libido enhancer, as well as a powerful pro-fertility agent. More importantly, D-aspartic acid possesses the remarkable ability to skyrocket testosterone levels whilst it’s continuously supplemented.

One example of D-aspartic acid influencing testosterone levels is this study which involved 43 male subjects who were administered with 3 g over the course of twelve days, and researchers noted increases in luteinizing hormone synthesis AND testosterone.

An altogether different study involving 60 infertile male subjects, were administered with 2.66 g of D-aspartic acid daily saw average increase in testosterone by up to 60%.

Testosterone can increase in as little as 12 days, especially in infertile men, but on a negative note, effects can be extremely short-lived.  Studies have shown that any increases in testosterone can vanish in as little as 4 weeks once supplementation is stopped!


D-Aspartic Acid Powder by AI Nutrition is certainly a good quality DAA supplement because it is sufficiently dosed. D-aspartic acid as an ingredient has repeatedly proven its libido/fertility enhancing potential, as well as its testosterone boosting properties.

Unfortunately effects can be extremely short-lived as testosterone levels can quickly return to where they were prior to supplementation in as little as four weeks, once a person stops taking it.

This means that you would need to constantly take this supplement for the foreseeable future in order to enjoy its benefits, and in the long run, this could mean having to spend quite a bit of cash!

D-Aspartic Acid Powder by AI Sports Nutrition Overall Rating

D-Aspartic Acid Powder is definitely an excellent DAA supplement because it appears to be sufficiently dosed, and the ingredient itself has repeatedly demonstrated a remarkable testosterone enhancing capacity.

On a negative note, as highlighted earlier, effects can be extremely short-lived, and without other quality ingredients to accompany D-aspartic acid such as BioPerine, fenugreek and zinc, this supplement is certainly limited in its scope.
