A Bite-Size Read for Your Health and Waistline
After my podcast episode about creatine, listeners started asking about their favorite pre-workout options. As both a podcast host and health coach, I always want to answer your questions. When Taylor sent in Optimum Nutrition’s AMIN.O. Energy for review, I figured, let’s go through it together and see what’s really inside.
Whether you’re lifting, biking, running, hiking, cycling, playing team sports, or just managing daily errands, Optimum Nutrition claims their AMIN.O. Energy + Electrolytes delivers caffeine from natural sources to support energy and focus, amino acids to aid muscle recovery, and electrolytes to replace what’s lost through sweat. They market it as something you can take anytime you want an energy boost, recovery support, or to replenish electrolytes. It sounds great on paper, and I’ll admit that the fancy flavor names like “tangerine wave” and “watermelon splash” make me laugh every time. Still, these names don’t tell us much about the actual nutrition.
Looking at the label for the strawberry burst flavor, the serving size is two scoops of powder. It contains 5 calories, 1 gram of carbohydrates, 0 grams of sugar, 60 milligrams of magnesium, 190 milligrams of chloride, 110 milligrams of sodium, and 45 milligrams of potassium. There’s also a 5-gram amino acid blend, which is a decent amount and uses mostly micronized forms. The electrolyte blend is 440 milligrams and includes sodium chloride, magnesium oxide, and potassium chloride. On top of that, there’s 100 milligrams of caffeine, 50 milligrams of green tea leaf extract, and 10 milligrams of green coffee bean extract.
I like that the amino acid blend is 5 grams and that they list the ingredients clearly. I would personally prefer to see branched-chain amino acids rather than only micronized ones, but micronized isn’t the worst option. What concerns me is that they don’t specify the exact type of magnesium used, other than magnesium oxide in the electrolyte blend. Magnesium oxide tends to be poorly absorbed and can even have a laxative effect for some people. The 440 milligrams of electrolytes isn’t a large amount either, so it’s a bit of a mixed bag. The quality and quantity of electrolytes could both be better.
When it comes to sodium and potassium, 110 milligrams and 45 milligrams are pretty low. That’s not enough to make a real difference in hydration or muscle recovery. I’d love to see them use higher-quality sodium sources, like dark pink Himalayan sea salt, but since the label doesn’t specify, I’m assuming they didn’t.
I’m guessing the 100 milligrams of caffeine is doing most of the work when it comes to the energy boost you might feel from this supplement. Research on green tea extract and athletic performance is inconsistent, and with only 50 milligrams here, the amount is far below the doses used in studies. The 10 milligrams of green coffee bean extract is also minimal when compared to research recommendations, which suggest anywhere between 90 and 1,000 milligrams for a noticeable effect. These ingredients feel like what I call “fairy dust” doses, meaning they’re there in name more than impact.
So, is this the best pre-workout supplement on the market? Not exactly. I appreciate the 5 grams of amino acids, but I’d prefer a focus on branched-chain amino acids and higher-quality electrolytes. You’ll probably feel something from the caffeine and amino acids, but the rest of the formula doesn’t offer much extra. Personally, I still prefer my go-to post-workout protein powder, which gives me 6.9 grams of branched-chain amino acids and 3 grams of creatine. That combination supports both muscle recovery and performance while keeping my nutrition balanced.
As far as wellness trends go, pre- and post-workout supplements can be useful tools, but they’re not all created equal. The best nutrition tips are still the simplest ones: read labels, know what you’re taking, and choose products that provide real value rather than hype.
This brings up a great question for all of us. Do you use a pre- or post-workout supplement? And if you do, what’s worked best for you?
