The Verdict
  • Targeted For Both Genders: Like BPI Sports BCAA Powder, Optimum Nutrition BCAA Capsules are not actually targeted specifically for women. That doesn't mean they're not a good option, however. They're still designed to promote lean muscle mass, reduce body fat, increase your metabolism, improve endurance, speed up muscle recovery and improve insulin sensitivity, all things equally beneficial for both men and women.
  • Unflavored: Unlike the other options on this list, this BCAA supplement is unflavored. This is because it is in a capsule form and you only need to quickly swallow it with a glass of water and not worry about taste. This does make it healthier, however, as there are no added sweeteners, artificial or natural and no added sugar.
  • 2:1:1 Ratio: Optimum Nutrition BCAA Capsules contain the preferred 2:1:1 BCAA ratio (2 parts leucine for every 1 part valine and 1 part isoleucine), which is proven to be the most effective way to maximize the effects of protein muscle synthesis to promote muscle growth and aid muscle recovery.
  • Capsule: Optimum Nutrition's BCAA supplement comes in a capsule form, in contrast to the other powder options on our list. Though possibly less convenient than powder form, the capsule is easily swallowed and contains no artificial flavors or sweeteners to give a nice taste.

The Good

  • Free From Artificial Flavors: Because this BCAA supplement comes in capsule, not powder form, it does not need a flavor to give an appealing taste. Therefore, this supplement contains no sugar and no artificial sweeteners or flavors. This makes it a healthy choice for people who want the advantages of BCAA supplementation, without the potential harmful effects of artificial ingredients.
  • Large Quantity: Optimum Nutrition BCAA Capsules come in a 7oz container, containing 200 capsules or 100 servings. This makes it an excellent option for those unwilling to spend the same amount for only 30 servings.
  • Perfect Pre and Post Workout: Optimum Nutrition BCAA Capsules are equally beneficial both before and after your workout. Taken before endurance training, this supplement can help endurance, strength and avoid sore muscles. Taken after strength training, they help kick-start protein synthesis, to promote muscle growth and improve muscle recovery.

The Bad

Although the capsule form can offer a lot of benefits, it can also be less convenient than powder form. Taking two capsules at specific intervals between meals can be more work than drinking a powder drink. However, it's easy to fall into the swing of things after you've been taking the supplement regularly and as they contain no flavors, they are a healthier option than flavored powders.

Also less convenient is the number of times you must take the capsules during the day for intended effect. Because one serving only contains 1g of BCAAs and 5g is the minimum that should be taken daily for best results, then you must take this supplement at regular intervals between meals to get the intended results. However, because there's a very specific time they must be taken (between meals, 30-45 minutes before workouts, or after workouts), it is easy to fall into a pattern of taking them at specific times. Also, once you fall into this pattern, it will encourage you not to pass on a workout as you'll have already taken your supplement beforehand.


1 serving is 2 capsules contains 1000mg of BCAAs, which should be taken between meals, 30-45 minutes before workouts and/or immediately after workouts.
