What You Need To Know About MAN Sports AAKG

MAN Sports AAKG is marketed as a performance enhancing supplement that may help improve endurance and muscle building. It contains just Arginine Alpha Ketoglutarate (AAKG) within the recommended dosage at 2500mg per serving, so if you were thinking of trying an AAKG supplement it might be a good choice.

Many bodybuilders use AAKG but there is no real evidence that it will work in the way as described and according to some clinical evidence it may actually have an adverse effect. However this supplement is reasonably well priced and contains 100 servings per tub, so it will not cost you too much if this is something you want to try out for yourself.

What Are The Side Effects Of MAN Sports AAKG?

Potential side effects seem to be related to blood pressure and may include dizziness and fainting. AAKG is also known to cause mild gastrointestinal upsets.

However you should avoid AAKG if you have or are prone to cold sores or genital herpes, because Arginine can make the condition worse. AAKG thins the blood so you must not take this if you have related issues, or are taking blood thinning medication such as Warfarin.

How Much Does MAN Sports AAKG Cost?

MAN Sports AAKG is not overly expensive. Buy from the official MAN Sports website and 1 x 250g tub (100 servings) costs $19.99. This is slightly more expensive than some comparable supplements on the market, but only by a few dollars.

Our Verdict On MAN Sports AAKG

We quite like MAN Sports AAKG. This straightforward supplement contains just the one ingredient, and we like that it comes in a flavourless powder you just add to water or your favourite juice. There is no nonsense about this supplement which we like.

The downside is that AAKG is not proven to work. According to scientific research it should work in theory because of its effect upon nitric oxide levels, endurance, and muscle building, but clinical trials carried out on athletes have found otherwise. Most research suggests it makes no difference at all to your performance and in one clinical trial carried out on 12 college athletes; it actually seemed to hamper performance.

That said, some bodybuilders use AAKG and seem to like it so if you wanted to test it out for yourself, MAN Sports AAKG would be as good a choice as any. But with the jury still out on Arginine Alpha Ketoglutarate, we do not recommend MAN Sports AAKG to our readers.

MAN Sports AAKG Review

MAN Sports AAKG is a flavourless powder that you add to a small glass of water or a drink of your own choosing. It can be taken pre and post workout on training days, and according to the directions you should also take it on non training days in the morning.

MAN Sports AAKG Facts

  • Each tub contains 25g, sufficient for 100 servings
  • You can stack this supplement with other products in the range; some experts suggest Creatine
  • Manufactured in micro batches

This supplement contains 2500mg of Arginine Alpha Ketoglutarate per serving and nothing else. Arginine Alpha Keoglurate or AAKG is a non essential amino acid, meaning that it does not have to be ingested by diet because it is already manufactured in the body. It plays a role in many functions including protein synthesis and helping the body build muscles, and it is also important in helping the liver make nitric oxide.

In the human body Nitric Oxide is crucially important. One thing it does is to relax the cells that line the interior of blood vessels (Endothelium) which widens the arteries and increases blood flow. Many athletes feel that doing this will enable them to exercise for longer and harder without pain. In addition, improving blood flow to the muscles also delivers more protein, carbs, and hormones. All important if you are trying to build muscle.

How to Take MAN Sports AAKG

  • Take one (1) level scoop (2.5g) daily, with a 4 oz. (120ml) of liquid pre & post workout.
  • On days off from training, take one (1) rounded scoop (2.5g) in the morning, or as directed by a healthcare professional.

MAN Sports is a supplements company based in Texas. Although the official address is provided as a PO Box in Mesquite, there is an official phone number so you can contact them if necessary. In addition, MAN Sports supplements are on sale from a wide range of outlets both in the USA and overseas, so you do not necessarily need to have direct dealings with the company anyway.

We have featured MAN supplements in previous reviews. Some of these include; MAN Sports L CarnitineMAN Sports Alpha Pro Nutrition VEX, and MAN Sports ISO Carb.

MAN Sports AAKG Concerns:

  • This supplement does not seem as easy to buy as other MAN Sports supplements. Does this suggest that this supplement is just not popular?
  • Clinical trials suggest that AAKG is not effective as a sports supplement, so why bother taking it?
  • Although the list of potential side effects is not long, messing with blood pressure levels can be dangerous for some users

What Does MAN Sports AAKG Claim To Do?

According to the advertising MAN Sports AAKG will cause;

  • Increase Nitric Oxide Production
  • Strength, Endurance, and Reduced Fatigue
  • HPLC Tested For Zero Impurities and Potency
  • Micro Batch Quality

HPLC refers to High-performance liquid chromatography, a technique used in chemistry to analyse each component in a mixture. All MAN Sports supplements are made in small batches (micro batches), which the advertising says results in better quality supplements.

The advertised benefits are;

  • Surging pumps
  • Increased endurance
  • Increased strength

These are the usual claims associated with AAKG supplements.

Does MAN Sports AAKG Work?

MAN Sports AAKG looks to be a pretty good AAKG supplement. It contains 2500mg per serving, which is in line with the recommended dosage of between 1500mg and 3000mg.

Some bodybuilders recommend adding Creatine based products to AAKG, which is an option and many people believe that this substance is effective for boosting performance and endurance.

However the evidence for AAKG debatable. Although AAKG is popular and looks pretty safe, there is no real evidence that it will work as described according to clinical evidence.

In one test, 24 men took 12 g of AAKG for 7 days (12 took an AAKG supplement, the others a placebo) and although heart rate, blood pressure, and blood flow were elevated in both groups, there was no difference between the two, and changes were obviously caused by the exercise rather than the supplement, although argnine levels were elevated in the control group.

Another study carried out on 12 college athletes found that ASAKG supplementation actually hindered exercise endurance. Source

According to Institute of Sports Nutrition, the claims about AAKG as a sports supplement are based on theory rather than results. It seems that AAKG and Arginine should work in the way as described, but there is very little scientific evidence to prove it. Source

It seems the jury is out on AAKG.

What Are The Ingredients of MAN Sports AAKG?

Serving size is equal to one 25g scoop of powder.

  • Arginine Alpha-Ketoglutarate (2:1) (2500mg): Dietary supplement that combines the amino acid Arginine, a building block of protein with alpha-ketoglurate, a compound that breaks down sugars and amino acids. These constituents both have different roles in the body and may offer benefits when combined as AAKG, but more research is needed. So far this formula has not demonstrated the claimed effects of increased endurance in clinical testing, and it requires further investigation. Source

Does MAN Sports AAKG Have Any Side Effects?

AAKG looks quite safe for most people, but there have been some reported side effects including;

  • Dizziness
  • Fainting
  • Lowered blood pressure
  • Mild gastrointestinal upset

You should avoid AAKG if you have or are prone to cold sores or genital herpes, because Arginine can make the condition worse.

AAKG can thin the blood so you should not take this if you are taking medication such as Warfarin.

Not suitable for individuals under 18. Avoid if you are pregnant or breast feeding. Speak to your doctor first if you have an underlying medical condition or are taking prescription medication, as this supplement could cause interactions.

Are There Any Customer Reviews For MAN Sports AAKG?
