Man Sports Iso-Amino

Branched Chain Amino Acid (BCAA) supplements are a straightforward and well-loved supplement by exercise and bodybuilding enthusiasts. Offering a blend of three amino acids, each supplement works to synthesise muscle protein, aiding in the process of muscle growth and limiting muscle damage and fatigue. As many BCAA supplements are very similar to each other, secondary factors such as pricing, flavourings and mixability become even more important when choosing the right BCAA supplement for you.

Below we take an in-depth look at Man Sports Iso-Amino to see what benefits it offers consumers.

What You Need To Know About Man Sports Iso-Amino

Man Sports Iso-Amino is a Branched Chain Amino Acid powder supplement. These amino acids are often used by those trying to build muscle, as they naturally aid with the muscle-building process and prevent muscle fatigue. Although BCAAs are only thought to be maximally effective for those with little protein in their diet (as they are naturally found in meat and eggs), most BCAA products work as advertised and provide customers with the promised benefits.

Man Sports, who manufacture Iso-Amino, offer a huge selection of thirteen different flavourings.

What Are The Side Effects Of Man Sports Iso-Amino?

BCAAs are not often associated with side effects; those that do take place are rare and not especially serious. Potential side effects include nausea, pain, and headaches. More serious side effects could develop if the supplement adversely interacts with existing medication. This could affect diabetics, those taking medication for Parkinson’s Disease, those taking thyroid supplements, and others. Check with your doctor to ensure that no adverse interactions take place, just in case.

How Much Does Man Sports Iso-Amino Cost?

Man Sports Iso-Amino can be purchased from the manufacturer’s official website. There are two sizes available, a smaller tub containing 30 servings which costs $28.99, and a larger tub containing 90 servings which costs $69.99.

The product is also available from numerous third party online retailers. However, not all third party retailers carry every flavour that is listed on the official website.

Our Verdict On Man Sports Iso-Amino

BCAA supplements do appear to benefit consumers who are trying to increase their muscle mass, especially when taken shortly before muscle building exercises.

Man Sports Iso-Amino is a BCAA supplement that provides a huge dose of five grams of BCAA per serving. Clinical trials appear to recommend dosages between 2.5 grams and 11 grams, meaning that dose is well within the effective range. The product offers a good ratio of Leucine, Valine and Isoleucine that studies suggest is the most effective ratio (2:1:1).

Man Sports offer a money back guarantee on their products when purchased direct from their official website. However, third party retailers do offer lower prices than the official Man Sports website. The product does appear to offer good value for money when working out the cost per serving. The larger tub offers the best value for money per serving, but the larger tub is available in only a few of the 13 flavours that the small tub is offered in.

Man Sports also produce a version of this supplement that can be used as a coffee creamer (Iso-Amino Coffee Creamer Bliss). This product is not as highly rated by customers as Iso-Amino, and customer reviews suggest that it is an incredibly sweet product, preventing many people from using a full serving in their coffee.

If you are looking for a good BCAA supplement, Man Sports Iso-Amino is definitely a good option, but we are less impressed by Iso-Amino Coffee Creamer Bliss as it appears to be too sweet for practicality. We do recommend Man Sports Iso-Amino to our readers. However, we do not recommend Man Sports Iso-Amino Coffee Creamer Bliss to our readers.

Man Sports Iso-Amino Review

Man Sports Iso-Amino is a Branched Chain Amino Acid supplement. They use the 2:1:1 ratio of Leucine, Valine, and Isoleucine, which studies suggest is the most effective ratio.

Branched Chain Amino Acids (BCAAs) are thought to stimulate protein synthesis in the body (to create lean muscle mass), prevent fatigue following strenuous exercise, and to promote glucose consumption by the body. The amount of muscle mass a person has plays a large role in their base metabolic rate, as muscle uses more calories to maintain than fat. Having more muscle mass therefore increases the metabolism. They are naturally found in food. Some good sources of these amino acids include: whey, milk, soy proteins, beef, chicken, fish, and eggs, baked beans, lima beans, chickpeas, lentils, whole wheat, brown rice, almonds, brazil nuts, cashews, and pumpkin seeds.

Man Sports Iso-Amino Facts

  • Manufactured by Man Sports
  • 30 or 90 servings per tub
  • Available in 13 flavours

There are numerous different flavours of Iso-Amino available. The full range of flavours is available when purchasing a tub of 30 servings, but the 90 servings tub is available in fewer flavours. Customers can choose between the following flavours: Rainbow Sherbert, Grape Bubblegum, Blue Bombsicle, Tiger’s Blood, Pineapple Express, Sour Batch, Sour Nukes, Dorks, Fruit Smash, Strawberry Kiwi, Green Apple, Tropic Thunder, and Mango.

Because Man Sports make micro batches of their products (claiming that this results in a higher quality product) it appears to give them a lot more freedom with the flavours they offer. As well as the list above, customer reviews also refer to some other flavours, including Sweet Delish, Starblast, and Blue Razz. It is possible that these were flavours with limited availability, or that they have been discontinued, but it is also possible that they could be relisted for sale in the future.

How to Take Man Sports Iso-Amino

Directions for use are as follows: As a dietary supplement, mix one serving (one level scoop) of ISO-AMINO with 8oz of water. Stir or shake and consume during exercise on training days, or throughout the day on both training and non-training days. Stack ISO-AMINO with Game Day and/or CLA Powder for enhanced results.

The product is also available as a coffee creamer, called Iso-Amino Coffee Creamer Bliss. Directions for the coffee creamer are as follows: As a dietary supplement, mix one serving (one level scoop) of ISO-AMINO with 10-12oz of coffee (cold or hot is fine). Stir or shake and consume. ISO-AMINO can be taken throughout the day on both training & non-training days.

Man Sports Iso-Amino is also available as a flavoured, dairy-free coffee creamer, called Man Sports Iso-Amino Coffee Creamer Bliss. It comes in French Vanilla or Hazelnut flavours, and there was also a Pumpkin Spice flavour that appears to have been a limited edition flavour for autumn.

ManSports Iso-Amino is manufactured by Man Sports, a company who are based in Texas in the USA. They can be contacted using the information provided on their official website.

What Does Man Sports Iso-Amino Claim To Do?

Man Sports state that each serving of Iso-Amino provides 5 grams of “pure, isolated” BCAAs, which will “burn fat and preserve lean muscle tissue”, as well as “accelerate endurance and recovery”. The formula is sugar free and contains no added colours or dyes.

Does Man Sports Iso-Amino Work?

BCAA supplementation may help to increase the body’s protein synthesis, if taken in adequate doses. Remember that BCAAs are also naturally occurring in numerous foods.

Consumers also need to combine the consumption of any BCAA supplement with muscle building exercises in order to make any difference to their muscle mass (and indirectly their metabolic rate); BCAA supplementation will not cause new muscle growth on its own! The product also has a small effect upon glucose consumption and uptake, referring to how the body stores glucose in cells before using it for energy. Increasing glucose consumption is one of many ways to increase the metabolism and although it may not be the most effective, it will have a small impact upon weight loss. BCAA supplements should be considered an exercise and workout supplement, as it will enhance the results of muscle building exercises rather than working wonders on its own.

Theoretically, Man Sports Iso-Amino will help consumers to increase their lean muscle mass, and may play a small role in boosting the body’s metabolic rate, both directly and indirectly. However, customers will notice no changes at all if they fail to exercise, especially if they fail to focus upon muscle-building exercises.

Each serving contains a total of 5 grams of Man Sports Iso-Amino, making it a very well dosed supplement.

What Are The Ingredients of Man Sports Iso-Amino?

The ingredients found in Man Sports Iso-Amino are detailed below. The ingredient quantities provided are per serving of one scoop (7 grams).


  • L-Leucine (Instantized, Ultra-Soluble) 2500mg: An essential branched chain amino acid which stimulates protein synthesis in the body, and is used as a building block for muscle. Whilst dieting, supplementing Leucine could help to maintain muscle mass whilst still losing fat mass, as it is used to help fuel muscle.
  • L-Valine (Instantized, Ultra-Soluble) 1250mg: Valine appears to be the least potent of the branched chain amino acids, but will still play a small role in stimulating protein synthesis and promoting glucose consumption and uptake. Source
  • L-Isoleucine (Instantized, Ultra-Soluble) 1250mg: Isoleucine appears to promote glucose consumption and uptake. It also plays a role in inducing muscle protein synthesis (although it is not as strong as Leucine). Source

Are There Any Customer Reviews For Man Sports Iso-Amino?

There are lots of customer reviews for Man Sports Iso-Amino, both on the manufacturer’s official website and on the websites of numerous third party retailers. The product is generally very highly rated in customer reviews, with many reviews praising the taste of the supplement.

Fantastic taste and mixability for a beginner! I bought ISO Aminos in Sourbatch and holy cow! It tastes just like Sour Patch kids, mixes great and has made a huge dent in my daily water consumption and pop cravings! I add almost double the suggested water to tame it down sometimes but it’s an amazing flavor and I feel the difference in muscle recovery and overall good feelings!

I consider myself a amino/bcaa junkie and these are some of the best flavors out there.

All of these flavors taste like CANDY! I am obsessed with the strawberry kiwi which is not a flavor I’d usually get but it’s now my favorite! Not too sweet or sour.

Love the flavor! Great taste, perfect to curb my soda & candy cravings and a great addition to my workout!

Awesome! Whenever I get a sugar craving I go make myself a cup of Iso-Aminos! They taste awesome and they make a huge difference with my weight loss journey so I can protect my lean muscle! Must have if you’re starting out with supplements!!

So far I have tried sweet delish, sour batch, and I currently have dorks. I love sour batch and dorks but sweet delish never really grew on me. I can’t wait to try starblast. Besides the flavors I noticed the bcaas help me out during all of my work outs. Awesome produce keep it up guys.

This stuff tastes Awesome. I drink it during workout and at my desk… Love that its not colored and it really helps with the after workout recovery… Top notch company

Love this product! It mixes well. Not chalking. I drink it during the sh which helps me drink all my water I need. I’ve tried sweet Delish, sour batch and green apple. Sour batch is my favorite because I love anything sour. But the other flavors are great too!

Best bcaa you can buy. Really seeing my recovery time shortening with regular use of this product. Also the best tasting aminos I have tried to date. Way to go man sports!

The customer reviews of the Coffee Creamer version of this supplement (Iso-Amino Coffee Creamer Bliss) are more mixed, but it is still a highly rated product. One consumer had an allergic reaction to the coffee creamer, as they have a wheat allergy (celiac disease); the product is manufactured in a facility where wheat products are also processed.

Was so excited to get the pumpkin spice for my husband, they claim they’re gluten free and he is allergic to wheat with celiac disease and he had a reaction to it after he drank it and when we read the fine print on the packaging and it said that the products are made on machines that process wheat. Very disappointed because the flavor was great and he enjoyed it going into it and then was sick as a dog because of his celiac reaction.

I didn’t care for the flavor. I bought the hazelnut. It tasted too sweet. It did mix right up like all of the other Man Sports products.

I’m obsessed with both the French vanilla and the pumpkin spice. It’s super sweet so a little goes a long way and I love it in the morning with my pre-cardio coffee!

Love Love Love this product!!! So excited that I can enjoy coffee again without adding all kinds of calories and sugar into it. Great flavor and is amazing in both hot and cold coffee!

A little sweet for my taste buds. I got it in the Hazelnut flavor and I must say “a little goes a long way”. The flavor is super intense and it’s really an alternative to other sweeteners. I would love to try other flavors in my next purchase.
