So, if you are looking for a pre-workout supplement rich in BCAAs, then ON’s amino energy can be a good choice.

Caffeine in ON’s Amino Energy

Optimum Nutrition’s Amino Energy contains 100 milligrams of caffeine per serving.

Caffeine is the most popular stimulant worldwide. You can always spot caffeine on the label of your favorite cola, chocolate, or energy drink.

It is a plant-based ingredient that stimulates your central nervous system and makes you alert. Caffeine in ON’s amino energy will make you more focused on your workout and enhance your cognitive abilities.

Caffeine may also trigger fat burning and boost the metabolic rate in the short term. But after a while, you may build a tolerance to it and not get affected much.

Even if caffeine doesn’t cause you to burn more calories in the long run, items containing it may suppress your appetite and help you eat less.

According to FDA, healthy adult should limit their caffeine to 400 milligrams a day. 100 mg of caffeine is far less than 400 mg but still, keep a tab on your caffeine intake to be on the safe side.

Drinking more caffeine than the said limit can backfire you and lead to the following consequences:

  • Hypertension
  • Stress and A
  • Stress and anxiety
  • Risk of stroke
  • Risk of low bone mineral density in women

Sugar in Amino Energy


ON’s Essential Amino energy has no sugar but it does have artificial sweeteners for taste.

Amino energy uses sucralose as a sugar substitute. Sucralose, also known as Splenda is a zero-calorie artificial sweetener that is 600 times sweeter than sucrose. Sucralose readily flows through the body and does not accumulate in the body as fat.

Sucralose, according to some studies, does not affect blood sugar or insulin levels in healthy adults. But, research also indicates that sucralose can boost blood sugar and insulin levels in obese adults who don’t use artificial sweeteners frequently.

Sucralose is deemed safe, except for those with phenylketonuria, a genetic disorder.

In the context of a healthy diet, added sugar is not better than artificial sugar. But sucralose delivers a greater sweetness in way smaller amounts than added sugar. Hence, sucralose in Amino Energy will not harm you if you take it moderately.

Calories in Amino Energy

For instance, if you have very less physical activity and rarely go for a walk you might need a lot lesser calories. And if you are an athlete or a gym freak you might have to eat more than 2000 calories.

Amino Energy’s label claims that it is meant to support you on your health and fitness journey and that it may be used “anytime”. It is also evident that Amino Energy has a lot fewer calories so you really don’t have to worry about gaining weight if you are using Amino Energy.
