An Insurance Plan for your Muscles

When you’re pushing yourself during training and racing, your muscles need a boosted supply of branched-chain amino acids (BCAAs) to help protect them from damage and to help rebuild. BCAAs are the building blocks of proteins, and your body can only get them from the foods you eat. BCAA Capsules may help maintain mental clarity, promote muscle recovery, and enhance muscle growth while you’re pushing your limits.† Each capsule delivers a 4:1:1 ratio of the three BCAAs (L-Leucine, L-Valine, and L-Isoleucine) to help promote muscle recovery along with B Vitamins that can help facilitate amino acid metabolism and energy production during exercise.†Jump to full details

Any Time’s a Good Time to Protect Your Muscles

Taking ROCTANE BCAA Capsules before, during, or after any activity can prevent muscle damage, enhance muscle growth, and maintain mental clarity.†

Branched-Chain Amino Acids (L-Leucine, L-Valine, and L-Isoleucine) are the three essential amino acids which can help reduce muscle fatigue during exercise and speed recovery post exercise.† These building blocks of proteins can be found naturally in your daily diet and are essential to maintaining a positive balance between muscle damage and muscle repair.†

May reduce mental fatigue and help decrease muscle damage during exercise


Amino acids are the building blocks of proteins, and proteins make up the structure of the body, including muscles. Amino acids are either produced in the body (“nonessential”), or they must be supplied from the diet (“essential”). BCAAs are essential amino acids, meaning they are not made in the body, yet they constitute more than one third of the protein found in human muscle tissue. Rich dietary sources of BCAAs can include dairy, egg, meat, poultry and fish.

Yes! We put BCAAs in all our products with the exception of our Hydration Tabs, ROCTANE Electrolyte, Magnesium and Probiotic Capsules.

Even the most committed athletes may not get enough BCAAs in their regular diet to help delay fatigue during extended exercise. And stopping fatigue during exercise means you can go stronger for longer.

We focus on two types of fatigue that can impact performance – “mental” and “muscular.” BCAA’s delay “mental fatigue” by competing with the amino acid tryptophan which is a precursor to serotonin, and serotonin creates sleepiness. “Muscular fatigue” is delayed because BCAAs are used as an additional energy source during prolonged exercise, when glycogen stores are becoming depleted.

This product is meant for anyone that wants to further support their energy and recovery efforts. As we know, BCAAs act as an additional energy source for the working muscles, has the properties to support muscle recovery, can improve VO2max, boost immunity and help you get more out of your workouts.

This is also a great product for the vegan or vegetarian athlete that cannot consume a whey protein recovery product but would like to get in more BCAAs.

As little as 1500mg can enhance muscle buildup and prevent muscle breakdown. You can take these anytime, however we recommend them primarily after exercise and especially on heavier training days.

Not to worry. Vitamin B is a water-soluble vitamin, so any excess intake will be eliminated in your urine.

Of course! And this will help performance if your nutrition during exercise does not contain BCAA.

Yes, it is safe for children.


General Recommendations of effort

BCAA Capsules are like insurance for your muscles. Take 2-4 BCAA capsules before, during, or after exercise to kick-start your recovery and return to the trail, track, or road stronger than ever.

Saving Grace!*

*So I know I don't have the science to back this 5-star review up, but I'm pretty sure these bad boys really helped me out on my last trail ultra. Recently completed a very technical and demanding 43 miler with VERY little training under my belt. Not only was I able to finish, but I also wasn't completely debilitated after, which should have been the case considering the pounding my untrained legs had taken over 12+ hours.

I took the pills per the directions on the bottle (4 before, 2 about every hour during and 4 more after). Also followed the race up with some of the GU Recovery drink. Still felt pretty tired and sore (as expected), but was surprised it wasn't worse and that I was able to go up and down stairs pretty easily 1.5-2 days following. Also my massage therapist noted that she would have expected my legs to be tighter following that type of effort.

Again, there are many factors at play here and it might have been a combination of things I did that helped, but I feel strongly these were a key component i(n addition to hydrating, taking GU roctane gels, chews, stroop waffles and the electrolyte capsules). GU has all the best running supplements in my opinion and can't recommend them enough! As such, would like to extend a personal thank you to GU for helping to keep me upright and moving forward this past weekend :)

Happy trails,
