D-Aspartic Acid Supplements Guide


If you have ever browsed through a selection of testosterone boosters, chances are that you have come across D-Aspartic Acid (DAA) supplements. Unlike many of its competitors, DAA has been shown to be clinically effective for patients with low testosterone levels.

It also has benefits that can be reaped by athletes and bodybuilders as well as men who are struggling with infertility. If you are considering trying DAA supplements, read on to find out more about what they are, their benefits, potential side effects, how to take them, and what to look for in a good DAA supplement.

What Are D-Aspartic Acid Supplements?

DAA supplements are made of D-Aspartic Acid, an amino acid that forms when the enzyme Aspartate Racemase gets converted in the testes, hypothalamus, and pituitary gland. Athletes and infertile men sometimes use this product, as it boosts testosterone. DAA can be found in foods containing soy protein, soy-based fat formula, simulated bacon, nondairy creamer, casein, and zein (corn protein). Additionally, DAA can be racemized from L-acetate while heating food. It is thought that pasteurization can double the amount of DAA in raw milk.

In the central part of the brain, DAA triggers hormone release, such as the growth hormone and follicle-stimulating hormone. DAA can build up in the testicles where it eventually prompts a small increase of testosterone.

DAA supplements appear to sustain this increase for about 6 to 12 days. It also seems to enhance fertility, as indicated by a study in which infertile men who took DAA supplementation for 90 days experienced a 60 to 100% seminal increase. 26.6% of the men reported that they were able to conceive as a result of the 90-day trial.

Benefits of D-Aspartic Acid

One of the biggest benefits of taking a DAA Supplement is that DAA has been thoroughly studied in clinical research. Although its effects are not fully known, there is outstanding proof that DAA works to boost testosterone and fertility in infertile men. DAA only works for men with low testosterone and infertility issues, as two previous studies indicate. Men with testosterone levels within the normal range do not seem to be affected by DAA supplements.

Athletes sometimes rely on DAA supplements to build muscle mass since fat and muscle creation in men is directly linked to testosterone secreted in the body. DAA supplements work best for building muscle mass when taken in conjunction with important vitamins and minerals, especially Vitamins B6 and B12, as well as folic acid. Although DAA supplements can successfully build and maintain muscle mass, should a man stop taking these supplements, they could see an obvious depletion in muscle mass and even experience muscle collapse unless they maintain a strong bodybuilding routine.

Finally, it has been found that DAA supplements can increase the production of the thyroid hormones T3 and T4 since DAA helps to create hydrogen peroxide via oxidation. An increase in these thyroid hormones can lead to an enhanced metabolic rate in the body, making it an ideal supplement for male athletes, especially bodybuilders.

Are There any Side Effects?

As with most supplements, there are some known side effects, and they tend to manifest a little bit differently from person to person. DAA supplements are good natural alternatives to prohormones and anabolic steroids, which can cause serious side effects (especially to your body’s endocrine system) if taken for an extended period of time. However, DAA supplements do have a few known side effects.

The first is that DAA supplements can cause an increase of dihydrotestosterone (DHT), which is an endogenous androgen sex steroid and hormone that initially triggers puberty. An abundance of DHT can lead to acne outbreaks and hair loss.

Secondly, DAA supplements might cause increases in estrogen levels, which can lead to a plethora of problems, including an inhibited libido, prostate issues, gynecomastia, and bloating. This side effect seems to be pretty rare and theoretically should not occur if you are following your recommended daily dosage and cycling pattern.

Women should avoid using DAA supplements since there is no clinical proof as to how it might affect them. Also, males under the age of 21 should refrain from taking DAA supplements. Males who suffer from hypergonadism (elevated testosterone levels) should avoid taking DAA supplements as well since they do not need them, and having an overabundance of testosterone can lead to minor testicle shrinkage, acne, reduced fertility, an enlarged prostate, and hair-loss.

It should also be noted that anyone who has elevated levels of DHT and/or estrogen or who has hyperthyroidism (in which too much T3 and T4 are produced by the thyroid gland) should not take DAA supplements.

How to Take D-Aspartic Acid

A standard daily dose of a DAA supplement is somewhere in the ballpark of 2,000 to 3,000 mg, and there are different protocols for daily intake based on the brand that manufactures it. A few clinical studies have tried diverse methods, including one in which men were given a continuous daily dosage of 2,000 mg per day without any major negative side effects.

For a powdered formula, you might be taking a single 3g serving each day mixed into a drink to be taken with a well-rounded breakfast. Taking these supplements at meal time seems to be the best method for taking them, but you should always follow recommendations.

Many who use DAA supplements like to cycle them in an “on” period of about 2 or 3 weeks, followed by an “off” time of approximately 1 to 2 weeks. They then repeat the cycle. Those taking over 5g per day sometimes like to split their dosages up into morning and evening doses. 20g seems to be the absolute maximum for how much to take, and that is extremely high for most people.

What to Look for in a Good D-Aspartic Acid Supplement

When looking for a good DAA supplement, the first thing you should do is consult with your doctor. Ask your doctor if they think DAA is the right supplement for you to take to boost testosterone production, build muscle mass, and/or combat infertility issues. Doctors sometimes have specific brands they recommend for good reasons, and they can give you a clearer idea of how much you should be taking and when you might expect to see some results.

Always check to make sure that whatever product you buy has been thoroughly tested for potency and purity of ingredients. Ideally, you should be taking a DAA supplement that only contains D-Aspartic Acid, which should be clearly indicated on the package’s Supplement Facts list.

In order to truly get your money’s worth, you should be looking for products that are geared to last you for about 3 to 4 months. Some powdered formulas and capsules come in bulk packaging and will save you some money in the long-run, whereas smaller-count capsules tend to only last about a month and are not really that cost-effective since you should plan on continuously cycling through your DAA supplements.

Some capsule forms do not seem to kick in as quickly as their powdered formula counterparts. You might have to take capsules multiple times a day for several weeks before you start to really feel their effects. If you do not have the time to keep popping pills into your mouth, you might want to consider finding a pure DAA powdered formula that you can take in a drink with breakfast.

D-Aspartic Acid supplements are some of the most well-researched hormone-boosting supplements available on the market. While they seem to be quite beneficial in helping men combat infertility issues and low testosterone levels, they also work well for athletes, bodybuilders, and any man looking for boost and maintain muscle mass.

If you think you might benefit from taking DAA supplements, contact your doctor to inquire as to how you might add these into your daily regimen.
