MAN Sports Beta-Alanine Key Features

MAN Sports Beta-Alanine is a supplement in powdered form, that you simply add to water or juice in order to make a drink. Unlike many other MAN Sports supplements, this one is in neutral flavour rather than the crazy choice of flavours we have come to associate with this brand.

Beta-Alanine is a modified version of the amino acid Alanine, which in turn is an amino acid (protein building block) of Carnosine.

Carnosine is concentrated in the muscles, although it is also found in other parts of the body including heart and brain. There is strong evidence that improving carnosine levels via supplement use can help improve athletic performance and endurance.

MAN Sports Beta-Alanine Key Points

  • Each 500g tub contains enough for 250 servings
  • Contains CarnoSyn as the sole ingredient
  • Comes only in neutral flavour

So, why take Beta-Alanine and not Carnosine? After all, both are available in supplement form? The answer is not straight forward and some people do take Carnosine supplements. However, Beta-Alanine is more easily absorbed by the body and is well researched as a dietary supplement. In addition, it seems that taking Beta-Alanine, the precursor of carnosine, may be more effective for raising carnosine levels than taking carnosine itself. This is a topic of debate amongst bodybuilders.

How to Take MAN Sports Beta-Alanine

  • As a dietary supplement consume 1-2 servings prior to exercise and again immediately post-workout on training days
  • Consume 1-2 servings between meals on non-training days

MAN Sports Beta-Alanine contains a branded product called CarnoSyn as the sole ingredient. CarnoSyn is a leading, some might say THE leading Beta-Alanine powder on the market.

CarnoSyn is safe and has been well researched. It is not available to buy directly by customers because it is only available to the supplements industry. However, it shows up in many supplements on the market such as well known brand, GNC with GNC Mega Men Sport.

Unlike many other supplements on the market, MAN Sports Beta-Alanine contains only CarnoSyn as the sole ingredient. It is not blended with other ingredients or even flavourings.

MAN Sports Beta-Alanine Concerns

  • We advise you to only take 1 serving at a time. Overdoing Beta-Alanine may cause tingling and your supply will run out very quickly
  • Although Beta-Alanine seems safe, you do seem to have to take it regularly. Is it really worth the hassle?
  • There is very little feedback available and this supplement is not on sale via Amazon as is the case with many other MAN Sports supplements. Why?

We have covered numerous MAN Sports supplements in previous reviews. Some of these like Beta-Alanine focus on a specific amino acid such as MAN Sports L Carnitine, and MAN Sports ISO Amino, a BCAA supplement.

Others are more general, such as MAN Sports Blockbuster, a pre-workout supplement.

What does MAN Sports Beta-Alanine claim to do?

According to the product information, there are three key features:


We can’t see the point of these last two claims. After all the sole ingredient has not been manufactured by MAN Sports, so taking the credit for quality is a bit like buying a shop bought cake and then passing it off as your own work.

There is a brief description of how Beta-Alanine works,

“Beta-Alanine is a non-essential beta-amino acid that raises muscle carnosine levels to increase muscular output. Commonly known for the “tingle” feeling it provides upon consumption, Beta-Alanine is one of the most sought after ingredients for muscular endurance and lactic acid buffering through raising muscle carnosine levels.”

The three ways that it is supposed to physically help you are as follows:

  • Increase strength
  • Increase endurance
  • Delay fatigue

Does MAN Sports Beta-Alanine work?

Yes. MAN Sports Beta-Alanine will work. It contains only CarnoSyn the market leader in all Beta-Alanine supplements so is a good quality product. The serving size is effective and equal to 2000mg, so take as advised before and after a workout as recommended and you are within the recommended standard dose of between 4000mg to 6000mg.

According to the International Society of Sports Nutrition, who carried out an overview of all the clinical testing into Beta-Alanine, the results were very impressive.

Here is the conclusion of the very positive findings:

  • Four weeks of beta-alanine supplementation (4-6 g daily) significantly augments muscle carnosine concentrations, thereby acting as an intracellular pH buffer.
  • Beta-alanine supplementation currently appears to be safe in healthy populations at recommended doses.
  • The only reported side effect is paraesthesia (i.e., tingling) but studies indicate this can be attenuated by using divided lower doses (1.6 g) or using a sustained-release formula.
  • Daily supplementation with 4 to 6 g of beta-alanine for at least 2 to 4 weeks has been shown to improve exercise performance, with more pronounced effects in open end-point tasks/time trials lasting 1 to 4 min in duration.
  • Beta-alanine attenuates neuromuscular fatigue, particularly in older subjects, and preliminary evidence indicates that beta-alanine may improve tactical performance.
  • Combining beta-alanine with other single or multi-ingredient supplements may be advantageous when the dose of beta-alanine is sufficient (i.e., 4-6 g daily) and the treatment duration is at least 4 weeks.


  • More research is needed to determine the effects of beta-alanine on strength, endurance performance beyond 25 min in duration, and other health-related benefits associated with carnosine. Source

Serving size is equal to two scoops or 2000mg. You are advised to take before and after your workout.

  • Beta-Alanine (as CarnoSyn) 2000mg: Leading brand used in many sports formulations to increase carnosine levels, and muscle building and endurance.

According to Carnosyn research scientist Dr Roger Harris, “The patented use of beta-alanine has resulted in a significant advancement in muscle science technology. CarnoSyn® beta-alanine has been proven effective in over 55 scientific studies, 15 of which have been published in peer-reviewed journals.” Source

MAN Sports Beta-Alanine Side Effects

Beta-Alanine (CarnoSyn) is safe according to the many clinical studies. The most noticeable side effect is a tingling sensation or skin flushing that you may experience after taking it. This is harmless but if it bothers you, the clinical advice is to take smaller serving sizes more regularly.

Caution: Not suitable for individuals under 18. Avoid if you are pregnant or breastfeeding. There is currently no information about whether Beta-Alanine causes drug interactions. However, it is best to speak to your doctor before use if you have an underlying health condition or are taking prescription medication.

MAN Sports Beta-Alanine Customer Feedback

There are no independent customer reviews available but there is one review left on the official MAN Sports product page.

It may seem a bit cliché but I totally feel like Super Woman when I take this with my ISO Aminno and Blockbuster! I’m able to absolutely kill my workouts regardless of how “not feeling it” I was prior to my shake! I love how it gives me the extra push to get my body and muscles right where I want!

Watchdog Verdict

MAN Sports Beta-Alanine looks to be a good quality Beta-Alanine supplement and could be a good choice if you are specifically looking for this type of specialised supplement. It contains only CarnoSyn as the sole ingredient, so if the claims about Beta-Alanine are correct, there is no reason why this supplement should not work effectively. In addition, we like that there are no added ingredients and that Beta-Alanine has been extensively tested and found to be safe.

We like the big tub of 250 servings and we think this looks pretty good for the price, especially if you are in the USA and buy directly from the MAN website. There is an advertised money-back guarantee, and overall we do recommend MAN Sports Beta-Alanine to our readers that looking to try this ingredient for themselves.
