MRM BCAA+G Reload Post-Workout Recovery Review – A “Natural” Product?

We receive free products to review and may receive commissions on purchases made through our links. See our disclosure page for details.

MRM is a supplement company based in Oceanside, California, and their name stands for “Metabolic Response Modifiers.” That seems to just mean “sports supplements” and their site claims that the company is “dedicated to furthering of nutritional modalities in the arena of Alternative Healthcare.”

Their branch chain amino acid supplement is unusual because it’s both extremely cheap and made without artificial sweeteners or colors. It’s also contains a lot more than just BCAAs.


MRM BCAA+G Reload Post-Workout Recovery Ingredients

One serving is three little scoops that add up to about 14 grams. That provides 10 calories and 2 grams of carbs — no protein, fat, or fiber to speak of.

A serving contains 3.5 grams of leucine, 1.5 grams of isoleucine, and 1 gram of valine. Most BCAAs have a 2 or 3:1:1 ratio of leucine to isoleucine and valine. MRM has a 7:3:2 ratio which is a little unusual, but not significantly different to a normal 3:1:1 ratio.

Other ingredients include a day’s intake of Vitamin B6, four percent of the RDI of sodium, 1.6 grams of beta-alanine, and 2 grams of glutamine.

The “other ingredients” mostly relate to flavorings: citric acid, natural watermelon flavor, stevia, monk fruit extract, trehalose (a type of carbohydrate made of glucose), plus some red beet powder and some silicon dioxide, an anti-caking agent.

Note that there are no artificial flavors, colors, or sweeteners, plus there’s no soy and no gums (like carrageenan) either.

MRM BCAA+G Reload Post-Workout Recovery Benefits and Effectiveness

The leucine, isoleucine, and valine have been linked to better muscle retention, endurance, and focus during workouts. This product is also pretty high in sodium (4 percent of your RDI) so it should help with hydration.

The beta-alanine, meanwhile, may help with endurance and possible even hypertrophy (though the hypertrophic effect may just be because it can help some people finish more reps). It’s a little unusual to have what most people use as a pre-workout as a significant part of what is ostensibly a post-workout recovery drink but everything suggests that MRM BCAA+G can be used as a pre-workout or intra-workout as well. However, 1.6 grams is a very small amount of beta-alanine that may not be that effective — 5 to 6 grams is what’s usually recommended to get a proper effect.

There are two grams of glutamine in this product as well. There’s nothing wrong with glutamine, but its reputation as a muscle builder is probably overblown. When taken as a supplement, most of it gets stored in the gut and doesn’t make its way to the muscles.

Lastly, the Vitamin B6 may help with muscle retention, so it’s always nice to see it in a workout supplement, particularly since we appear to lose B6 when we exercise.

MRM BCAA+G Reload Post-Workout Recovery Price

You can pick up 840 grams for $29, which will provide 60 servings for about 48 cents each. Each serving provides about 5 grams of BCAA, so that’s 9.6 cents per gram of BCAA. That’s very cheap — most  of the popular inexpensive brands stay around 11 cents per gram of BCAA.

MRM BCAA+G Reload Post-Workout Recovery Taste

I tried the Watermelon flavor and unfortunately, it wasn’t great. While there’s certainly a market for tasty, naturally sweetened BCAAs, it doesn’t seem to me like MRM has perfected their taste formula yet. Although it contains the flavorings stevia, malic acid, citric acid, natural watermelon flavor, and even monk fruit extract, this product was a bit bitter, and didn’t really taste too much like watermelon.

The Takeaway

It’s rare to find an inexpensive BCAA that’s naturally sweetened and an effective supplement. That’s MRM BCAA+G, which has a good ratio of BCAAs, has nothing artificial, and is very cheap. Unfortunately, I found the taste to be a bit lacking. However, for a lot of people, this may be a worthwhile sacrifice given how rare it is to find an effective, “all-natural” product like this one.

Nick is a content producer and journalist with over seven years’ experience reporting on four continents. His first articles about health were on a cholera outbreak in rural Kenya while he was reporting for a French humanitarian organization. His next writing job was covering the nightlife scene in Shanghai. He’s written on a lot of things.

After Shanghai, he went on to produce a radio documentary about bodybuilding in Australia before finishing his Master’s degrees in Journalism and International Relations and heading to New York City. Here, he’s been writing on health full time for more than five years for outlets like BarBend, Men's Health, VICE, and Popular Science.

No fan of writing in the third person, Nick’s passion for health stems from an interest in self improvement: How do we reach our potential?

Questions like these took him through a lot of different areas of health and fitness like gymnastics, vegetarianism, kettlebell training, fasting, CrossFit, Paleo, and so on, until he realized (or decided) that strength training fit best with the ideas of continuous, measurable self improvement.

At BarBend his writing focuses a little more on nutrition and long-form content with a heaping dose of strength training. His underlying belief is in the middle path: you don’t have to count every calorie and complete every workout in order to benefit from a healthy lifestyle and a stronger body. Plus, big traps are cool.
