Universal Nutrition BCAA Stack Product Specifics

This product contains the same ratio and dosages of BCAAs as most other supplements: 2.5g of leucine, 1.25g of isoleucine, and 1.25g of valine. In addition to the three BCAA amino acids, this supplement also contains L-glutamine. There’s no sugar in this product, but it’s sweetened with aspartame. Your body metabolizes aspartame into methanol, which is toxic in large quantities (1). There’s research examining aspartame’s possible carcinogenetic effects, but results are still inconclusive. If you want to be safe and avoid aspartame, you may want to choose a supplement that contains sucralose as a sweetener.

Ingredients In Universal Nutrition BCAA Stack

  • BCAAs: All three BCAAs are essential, meaning that your body can’t produce them. Some people mistakenly take BCAAs with the intent of building muscle. However, research shows that BCAAs taken without other amino acids have little muscle building effect (2, 3). If you’re trying to bulk up, consuming a high-quality protein source like whey after your workout will have a bigger effect. BCAAs, especially leucine, can increase spare muscle when you’re in a caloric deficit (4, 5). So you may notice the most benefit from BCAAs when you’re cutting. BCAAs may also reduce post-workout fatigue (6).
  • L-Glutamine: L-glutamine is an extremely common non-essential amino acid. In fact, it’s the most common amino acid in your blood (7). Glutamine supplementation likely won’t affect your exercise performance (8, 9). However, some research shows that it may have benefits for decreasing post-workout muscle soreness (10).
