EAA Supplements: buying guide
EAAs, BCAAs or protein powder?
- Protein powder already contains all the essential amino acids plus more protein per serve, and is usually the best value if you just need more protein.
- EAAs are a light, low-calorie drink with every essential amino acid. Good for sipping during training or if you do not like protein shakes.
- BCAAs contain only three amino acids, so EAAs are the more complete choice. See do you need BCAAs?
What to check
- Grams of EAAs per serve, not just total powder.
- Extras such as electrolytes or caffeine (some "energy" aminos contain caffeine).
- Flavour, since you will be sipping it often.

EAA Supplements: questions and answers
Are EAAs better than BCAAs?
EAAs include all nine essential amino acids, while BCAAs contain only three of them. To build muscle your body needs all the essential amino acids, so EAAs, or simply protein, are the more complete option.
Do I need EAAs if I take protein powder?
Not necessarily. If you eat enough protein, an EAA drink is optional. Many people still enjoy one during training for taste and hydration.
Where can I buy EAAs in Melbourne?
You can buy EAAs online or at Supps247 stores around Melbourne, including Wyndham Vale and Moonee Ponds. Popular picks include R1 Essential Amino 9 by Rule One, Legit Recovery EAA Formula, Xtend EAA and Ghost Amino EAA + BCAA, so you can compare grams of EAAs per scoop and flavours on the shelf. Stock varies by store, so check the product page or call before you go. Online orders ship Australia-wide, usually in 2 to 8 business days, and orders of $99.99 or more ship free. Find your nearest store.
Do EAA drinks contain caffeine?
Some do. Energy versions such as R1 Essential Amino 9 + Energy, Rule 1 R1 Energized Amino and Optimum Nutrition Essential AMIN.O. Energy add caffeine, and R1 Energized Amino lists 120 mg per scoop. Count these in your daily total with coffee and pre-workout, as the AIS suggests most adults keep to 400 mg a day from all sources. If you sip aminos in the evening or are sensitive to caffeine, choose a stim-free formula such as R1 Essential Amino 9, which has no stimulants on its panel. Always read the label, because formulas can change.
Are EAA supplements safe, and do they have side effects?
Essential amino acids are the same building blocks found in protein foods. The NIH Office of Dietary Supplements reports no safety concerns for athletes eating up to about 2 g of protein per kilogram of body weight a day, and an EAA drink counts toward that total. Most side effects people notice come from extras: energy aminos such as R1 Energized Amino add 120 mg of caffeine per scoop, which healthdirect notes can affect sleep. If you have kidney or liver disease, are pregnant or take medication, check with your GP before using essential amino acid supplements.
Do EAAs work for muscle growth?
They can help, mainly by topping up protein. The ISSN nutrient timing position stand notes that about 10 g of essential amino acids can maximally stimulate muscle protein synthesis, and the ISSN protein position stand says it is the EAAs that drive that response. Growth still depends mostly on training and total daily protein, about 1.4 to 2.0 g per kilogram for most active people. So compare grams of EAAs per scoop: R1 Essential Amino 9 lists 7.5 g, while Primabolics Intrawar 3.0 lists 10 g per two-scoop serve. An EAA drink adds to good meals rather than replacing them.
Should I drink EAAs during my workout?
You can, and many people sip them through a session for flavour and fluid. Intra-workout formulas like Ghost Intra EAA + BCAA, with 10 g of EAAs plus electrolytes per scoop, are made for this. Timing is a smaller factor than people think, though. The ISSN nutrient timing position stand says your main focus should be total daily protein, ideally spread evenly through the day, and that quality protein eaten in the two hours after training gives a strong muscle-building response. An EAA drink during your workout is a convenient extra, not a must.
Are EAAs different for men and women?
The amino acids and label serves are the same. What differs is how much protein you need, which mostly follows body weight. The ISSN protein position stand suggests about 0.25 g of high-quality protein per kilogram per meal, or 20 to 40 g, for active adults. A separate ISSN position stand on female athletes suggests women around and after menopause aim for protein servings with about 10 g of EAAs. Caffeine-free options such as R1 Essential Amino 9 suit men and women alike, but check the panel, since energy versions add caffeine.
