    Easily my favorite supplement

    Gets me through my workouts and my workdays. I love this product, I’ve tried the blue raspberry and the watermelon and both are delicious. It also mixes really well, all around, great product.

    Good, but...

    I wouldn’t ever take a supplement like this again. I’ll just stick to a normal preworkout or testosterone booster. It just didn’t blow me away.

    Great Product!

    It tastes good, gives me energy, gets me to the gym and keeps me there 3-4 times a week for 2-3 hours. I’ve never before been able to stick with a workout for long, but I’ve been regular for almost a year now. I don’t feel any jitters with this product either.

    Gives me a boost and help recovery

    As an older person (65) recovery takes a little longer. I’ve found this product to help. I take it pre workout for a little boost and I enjoy the taste of the orange flavor

    Amino Energy

    Awesome product! I can definitely feel the energy before I even get my running clothes on and it doesn’t leave you with a “hangover” feeling like some energy supplements. The Blue Raspberry is delish!

    great product

    esupplements saved me money on this product. This is a great BCCA and energy boost before a workout. I personally like the lemon lime it taste like the lemon lime gatorade and the grape taste like a FANTA soda. it is very strong but good.

    Love this!!

    I’ve tried a lot of green apple supplements and this is by far the best tasting one out there! I love that it has the BCAAS, pre-workout and is only 5 calories! The previous pre-workout I used was 60 calories per serving and had no BCAAS. If you are looking for something that will get your heart pounding out of your chest this is not going to do that. This gives you the burst of energy you need to workout without the jitters. I actually drink 3 servings per day. (Not all at once). Can’t wait to try the other flavors but green apple is always my fav!

    AMAZING PRODUCT

    This Amino energy is awesome. I have tried LEMON LIME, GRAPE AND WATER MELON and they all taste amazing. I do 3-4 scoops and it gives me a great 6 hour burst of energy, sometimes I don’t want to leave the gym!! I can defiantly tell a difference in my performance on days I don’t take this. Unlike Pre-workouts this does NOT make you get the shakes or that tingly feeling. Highly recommended to all of my friends.

    Tastes great and low calorie!!!

    5 star all the way on these!!! I’ve tried so many energy drinks/pre-workouts/BCAAS and these are the best tasting ones BY FAR. i can’t believe they taste this good and are only 5 calories. I’ve had the Green apple and Lemon-lime. They are a little milder than some pre-workouts but you can increase the number of scoops if you like to have your heart beating out of your chest energy drinks. I like that that I can either add an extra scoop if I want more energy or I can just have another one later for a pick me up. The BCAA part is just icing on the cake! I won’t waste my time with other brands ever again.

      Re: is it this product safe for diabetics?

      The intake of amino acid supplements such as Essential AmiN.O. Energy may be beneficial for those with diabetes as it may decrease plasma glucose and improve insulin sensitivity. However, the long term effects need further studying. Talk to your physician before using any amino acid products.

    HMB 2222 Essential AmiN.O. Energy

    Overview

    Optimum Nutrition AmiN.O. Energy delivers a unique combination of critical amino acids and caffeine for a boost of energy and alertness in a refreshing fruit flavored formula.

    Directions

    Mix two scoops of Essential AmiN.O. Energy in 10-12 oz of cold water.

    Warnings

    Keep out of reach of children. Speak with a doctor before use if you are under the age of 18, pregnant, nursing, have a medical condition, or are taking medication.

    Featured Ingredients

    Glutamine – Glutamine is an essential amino acid for recovery due to its ability to reduce risk of exercise-induced infection and to enhance the rate of glycogen accumulation in muscle following exhaustive exercise.

    Arginine – As a precursor to nitric oxide, arginine leads to system-wide vasodilation (widening of blood vessels) for a more efficient flow of blood, nutrients, and oxygen to hard working muscles when they need it most.

    Leucine – Leucine is commonly referred to as the anabolic trigger due to its ability to activate and accelerate the mTOR pathway, a series of proteins responsible for muscle cell proliferation and synthesis. Leucine helps you stay fueled and primed for peak growth and strength.

    Beta-Alanine – This beta-amino acid combines with histidine to form carnosine, the muscles primary defense against lactic acid build-up. With less acid accumulating in muscles under anaerobic conditions, beta-alanine allows you to lift heavier and longer without premature fatigue or burnout.

    Green Tea – AmiN.O. Energy delivers 100 mg of caffeine from green coffee and green tea extracts that provide a variety of benefits. It sharpens focus and alertness, increases energy and strength, and ignites metabolism for greater fat burning.

    Q. What is AmiN.O. Energy?

    A. AmiN.O. Energy is a unique combination of critical amino acids and caffeine combined in a refreshing fruit flavored boost of energy and alertness. It can be taken as an afternoon pick-me-up or as a pre-workout amino acid boost.

    Q. When Should I Take AmiN.O. Energy?

    A. The best times to take AmiN.O. Energy are right before you workout, first thing in the morning, or in the afternoon when you start to feel sluggish. Avoid taking AmiN.O. Energy too close to bedtime as it may cause restlessness.

    Q. How Much Caffeine is in AmiN.O. Energy?

    A. Each serving of AmiN.O. Energy contains 100 mg of caffeine from natural green coffee and green tea extracts. This is about the same amount that is found in approximately 1 cup of black coffee.

    Q. Are the Ingredients in AmiN.O. Energy Safe?

    A. AmiN.O. Energy features all-natural ingredients and energizing compounds from natural sources. It is 100% safe and effective when used as directed to help support muscles and provide energy and focus.
