GNC’s branched-chain amino acids 1800 include 3 essential amino acids (EAAs). These are critical for various health benefits like building/repairing muscle and others. Studies show that BCAAs are especially helpful for these functions even though enough of all 20 aminos are required for building lean muscle mass.


A. What time of day should it be taken?

GNC’s branched-chain amino acids 1800 can be taken just about anytime during the day. This includes before/after meals or workouts. A big factor is the results you want to get. For example, you can use the BCAAs as a pre-workout supplement to boost workout performance. You can also use it afterward for post-workout recovery.

B. How long does it take to kick in?

The body can absorb gel capsules in a couple of minutes. This differs from tablets that often take up to half an hour for the body to absorb. So you should expect to experience the BCAA’s effects relatively soon. This is a plus if you’re using the supplements for factors like muscle building/repairing, etc. In those cases, you’ll want to get the fastest results possible.

C. How many can you take in a day?

The recommended dosage is 6 capsules/day. However, you should certainly talk with your doctor before you start taking the BCAA supplements. He/She can help guide you about the right dosage for your particular needs.

For example, in some cases, a lower dosage might be required. Your doctor can help to figure out the proper dosage based on your age, overall health, fitness level, etc.

What are the side effects, if any?

There are some possible side-effects from BCAAs including:

  • Headaches
  • Fatigue
  • Insulin resistance
  • Nausea
  • Blood sugar changes
  • Loss of coordination

There’s no guarantee that anyone taking BCAAs will experience one or all of these side effects. However, it’s important to know about them so you can be aware of the possible ones you could experience from the BCAAs.

What are the benefits?

1. 40-day supply

GNC’s branched-chain amino acids 1800 can last for 40 days or more if you follow the 6 capsules/day dosage. This can save money since each capsule works out to less than 10 cents per piece. In some cases, your doctor will suggest a lower dosage, which will increase how long the product lasts.

These supplements are absorbed by the body faster than tablets. This is a plus when you want to experience the benefits of the BCAAs faster. This includes a pre-workout supplement, for example.

Another benefit of capsules is they’re easier to consume versus tablets. This can be a plus in different situations like if you often have problems taking pills. It will be less of a problem with capsules.

5. Value

This is another key benefit of this product. The average cost per capsule is about 7-cents, which is quite low. Even with the recommended dosage of 6 pieces, it works out to less than 50 cents/day.

6. Muscle Building

BCAAs might help with fighting muscle breakdown, which can slow down muscle building. This is a key feature that can help you build lean muscle mass and reach your fitness goals. If you want to build muscle mass one of the main goals is to increase the ratio of “protein synthesis” and muscle breakdown. This can help you boost muscle gains.

7. Vitamin E

The supplement also includes Vitamin E, which is important for various functions. This is one of the natural antioxidants found in various foods like fish oil. It’s also good for heart health and provides antioxidant protection after tough workouts. This is an important vitamin for good health.

What is the price? How does it compare to competitor products?

This product is available in the under-$30 price range. It works out to about $0.07 per tablet. This is definitely a reasonable price since it’s a niche product like BCAAs.
