What Are Amino Blends?

Amino blends combine amino acids, such as BCAAs, EAAs or both, with other ingredients in one flavoured drink. Common additions include caffeine, electrolytes like sodium, potassium and magnesium, and extra amino acids such as glutamine or citrulline. They're usually mixed with water and sipped before or during training, or through the day.

At Nutrition Warehouse, we stock amino blends from Optimum Nutrition, Rule 1 Proteins, Primabolics, International Protein and more. They're part of our full amino acid supplements range. Want to see which ones customers rate highest? Check out our Top 10 Amino Acids.

Types of Amino Blends

Amino blends vary based on what's added to the amino acids. Here's how they compare:

Formulas vary by product, so always check the label for the amino acids, caffeine and other ingredients in each serve.

Amino Blends vs BCAAs vs EAAs

• BCAAs: 3 essential amino acids (leucine, isoleucine and valine), sometimes on their own.
• EAAs: all 9 essential amino acids, including the 3 BCAAs.
• Amino blends: BCAAs, EAAs or both, plus extras such as caffeine or electrolytes, in one drink.

If you want a single drink that covers aminos plus an energy hit or electrolytes, an amino blend saves mixing several products.

Energy Aminos and Caffeine

Energy aminos contain added caffeine, often from natural sources such as green coffee bean or tea. The amount varies between products. For example, Energized Amino by Rule 1 Proteins lists 120mg of caffeine per serve. Check the caffeine per serve on the label and count it alongside any pre-workout, coffee or energy drinks you have that day. Products containing caffeine are not suitable for children or for pregnant or breastfeeding women. If you train later in the day or prefer to avoid caffeine, choose a caffeine-free amino blend instead.

How to Choose the Right Amino Blend

1. Caffeine or caffeine free: energy aminos for a caffeine hit, or a caffeine-free blend for evening training and all-day sipping.
2. Electrolytes: choose a blend with added sodium, potassium and magnesium if you want aminos and electrolytes in one drink.
3. Amino acids per serve: compare the grams of BCAAs or EAAs in a full serve, not just the total blend weight.
4. Dietary needs: check the label for allergens. For example, PeptoPro® is a hydrolysed milk protein.
5. Cost per serve: compare the number of serves per tub, as tubs range from around 30 to 65 serves.

How to Take Amino Blends

Always follow the serving size and directions on your product label. Most amino blends are mixed with water and sipped before or during training, or through the day. Some energy aminos let you adjust the number of scoops, so start with the smallest serve on the label. Amino blends are not a replacement for a balanced diet. If you have a medical condition or take medication, speak to your healthcare professional before use.
