Best BCAA and EAA Supplements in Australia

BCAA and EAA drinks are some of the most popular products on our shelves, but they are not all the same. Some give you three amino acids, some give you all nine essential ones, and some add electrolytes or caffeine. This page lists our top BCAA and EAA picks at Supps247, starting from what our customers buy most in our stores and online, with amino acids per serve checked against each label. We also explain where the evidence sits. Updated October 2026.

Our top picks at a glance

1. Xtend Original BCAA by Scivation: best overall BCAA

Xtend Original is by far the most popular amino product at Supps247, outselling every other BCAA or EAA we stock by a wide margin over the last six months. Each serve gives 7 g of BCAAs with added electrolytes and zero sugar, it comes in nine flavours, and the 30 serve tub is one of the lowest-cost options per serve on this page. If you like a flavoured drink to sip through training, it is the easy starting point.

• BCAAs: 7 g per serve (front label)
• Added electrolytes; zero sugar
• 30 servings per tub
• Nine flavours at Supps247, including Blue Raspberry Ice, Watermelon Explosion and Smash Apple

Worth knowing: BCAAs are only three of the nine essential amino acids, and the AIS has agreed to place BCAAs in Group C (evidence not supportive of benefit for athletes). Xtend is a flavoured training drink rather than a substitute for protein.

2. Rapid Recovery by Rapid Supps: best EAA with a full label

Rapid Recovery gives you all nine essential amino acids with every one listed in milligrams, which not every amino product does. A 10 g scoop provides 7.2 g of EAAs, including 5.55 g of BCAAs in a 2:1:1 ratio and 2.78 g of leucine. It is made in Australia, sweetened with stevia, and has no sugar, so it suits sipping during training or between meals.

• Per 10 g serve: 7.2 g protein from EAAs; 0 g sugars; 38 mg sodium
• Leucine 2,775 mg, valine 1,388 mg, isoleucine 1,388 mg, lysine 600 mg, threonine 500 mg, methionine 180 mg, phenylalanine 150 mg, histidine 120 mg, tryptophan 100 mg
• 30 servings per tub
• Made in Australia; sweetened with stevia

Worth knowing: it contains phenylalanine, so it is not suitable for people with phenylketonuria. It is made on a line that also handles milk, gluten, soy, egg, nuts and seeds.

3. Intrawar 3.0 by Primabolics: best high-dose intra-workout EAA

Intrawar 3.0 is our second best-selling amino product and the highest EAA dose on this page. The label lists 10,000 mg of EAAs, 1,100 mg of an electrolyte formula and 2,000 mg of L-citrulline per serve, with citrulline, agmatine, creatine and betaine also called out on the tub. It is Australian owned and made, and suits long sessions where you want aminos and hydration in one bottle.

• Per serve (front label): 10,000 mg EAAs, 1,100 mg electrolyte formula, 2,000 mg L-citrulline
• Tub also lists agmatine, creatine and betaine
• 40 scoops, net weight 394 g (Mango Nectar)
• Australian owned and manufactured

Worth knowing: the listed actives add up to more than one scoop weighs, so a full serve is likely more than one scoop and the tub will give fewer than 40 full serves. Check the directions on the back label. It also contains creatine and agmatine, so it is more than a simple amino drink.

4. R1 Active BCAA: best for tested sport

R1 Active BCAA combines 5 g of BCAAs with 1.5 g of L-glutamine, 1 g of citrulline, coconut water powder and an electrolyte blend, with no stimulants. Rule One states it is Informed Choice certified and regularly tested for banned substances by the LGC lab, which makes it a sensible pick for athletes in drug-tested sports. It is also one of the cheapest picks per serve.

• BCAAs: 5 g per serve
• L-glutamine 1.5 g, citrulline 1 g, coconut water powder 350 mg, electrolyte blend 350 mg
• No stimulants
• 30 servings per tub
• Informed Choice certified, according to Rule One

Worth knowing: the brand page does not break the electrolyte blend into sodium and potassium, so it is a light hydration add-on rather than a full electrolyte drink. Like all BCAA products, it does not supply all nine essential amino acids.

5. R1 BCAAs by Rule One: best unflavoured

R1 BCAAs is a simple, micronised BCAA powder with 5 g per serve in a 2:1:1 ratio of leucine to isoleucine and valine. The unflavoured version is the only unflavoured amino product on this page, so you can add it to a shake or pre-workout you already like. Flavoured versions are also available, and some flavours are currently priced lower than others.

• BCAAs: 5 g per serve, 2:1:1 leucine to isoleucine and valine
• Micronised for mixing
• 30 servings per tub
• Flavours at Supps247 include Unflavoured, Blue Raspberry, Fruit Punch, Grape and Peach Mango

Worth knowing: the AIS notes BCAAs are poorly soluble in water and bitter tasting, so the unflavoured version may not be pleasant on its own. It is a BCAA product only, with no other essential amino acids.

6. Optimum Nutrition Essential AMIN.O. Energy: best with caffeine

AMIN.O. Energy is the pick if you want a light energy lift with your aminos. Each serve gives 5 g of amino acids and 100 mg of caffeine from coffee bean and tea leaf sources, with zero sugar. Mixed into 330 mL of cold water, it works as a lighter alternative to a full pre-workout or an afternoon drink before training.

• Amino acids: 5 g per serve
• Caffeine: 100 mg per serve, from coffee bean and tea leaf
• Zero sugar; 30 servings per tub
• Serve: about 2 scoops in 330 mL cold water

Worth knowing: it contains caffeine, so count it towards your daily total and avoid it close to bedtime. The 5 g amino blend is lower than the dedicated EAA picks here.

7. AminoJect BCAA by Evogen: best fermented BCAA with glutamine

AminoJect uses fermented BCAAs and fermented L-glutamine, which suits people who want to know their amino acids come from fermentation rather than other sources. A 16.8 g scoop gives 6 g of BCAAs in a 2:1:1 ratio, 5 g of glutamine, 1 g each of citrulline malate and betaine, and an electrolyte complex, with zero calories on the panel.

• Per 16.8 g scoop: L-leucine 3 g, L-isoleucine 1.5 g, L-valine 1.5 g, L-glutamine 5 g (all fermented)
• L-citrulline DL-malate 1 g, betaine anhydrous 1 g
• Sodium 130 mg, potassium 80 mg, magnesium 35 mg, calcium 51 mg
• About 30 servings per tub

Worth knowing: it is the most expensive pick per serve. It is sweetened with sucralose and acesulfame potassium, and made in a facility that also processes peanuts, wheat and eggs.

How we chose

We ranked BCAA and EAA products by units sold across Supps247 stores and online in the last six months, then made sure the list covered different needs, such as caffeine or stimulant-free, unflavoured, and third-party tested. We checked amino acids per serve and key ingredients against brand labels and label images in October 2026, and left out products we could not verify. Value tiers are based on price per serve at the time of writing. Brands do not pay for placement.

How to choose a BCAA or EAA supplement

Know the difference. BCAAs are three amino acids: leucine, isoleucine and valine. EAAs are all nine essential amino acids, which include the three BCAAs. A review in the Journal of the International Society of Sports Nutrition concluded that the claim that BCAAs alone stimulate muscle protein synthesis is unwarranted, because a meaningful increase needs all the amino acid building blocks (Wolfe, 2017). If you are choosing between the two, an EAA product covers more.

Be realistic about the evidence. The Australian Institute of Sport has agreed to place BCAAs in Group C, its category for supplements where scientific evidence does not support a benefit for athletes or where research is lacking (AIS Group C). Many people still enjoy a flavoured amino drink during training, but it should not replace protein-rich food.

Compare with a protein serve. The ISSN suggests 20 to 40 g of high-quality protein per serve with about 700 to 3,000 mg of leucine, and recommends focusing on whole food proteins that contain all the EAAs (ISSN position stand). The AIS says a protein supplement giving 20 to 40 g per serve meets most sports nutrition needs (AIS protein fact sheet). By comparison, the picks here give 5 to 10 g of amino acids.

Check what else is in the tub. Many amino drinks add electrolytes, citrulline, glutamine, betaine, creatine or caffeine. That can be useful, but it changes how and when you should take them, and it matters if you also use a pre-workout.

If you are drug tested, look for batch testing. The IOC notes supplements can contain undeclared prohibited substances and that third-party schemes help manage this risk (IOC consensus statement). Athletes who are drug tested should choose batch-tested products, for example HASTA or Informed Sport certified, and check with their sport.

FAQs

What is the difference between BCAAs and EAAs?

BCAAs are three amino acids: leucine, isoleucine and valine. EAAs are all nine amino acids your body cannot make, including those three. Research suggests building muscle protein needs all nine to be available, which is why EAA products such as Rapid Recovery and Intrawar 3.0 cover more than BCAA-only products.

Do I need BCAAs if I eat enough protein?

Probably not for muscle building. Protein-rich foods and protein powders already contain BCAAs along with the other essential amino acids, and the AIS has agreed to place BCAAs in Group C. Some people still like an amino drink for flavour and hydration during long sessions, which is a personal choice.

When should I take an amino acid drink?

Follow the directions on the label. Most of the picks here are designed to be sipped before, during or after training, or between meals. If your goal is muscle recovery, the ISSN and AIS both point to 20 to 40 g of protein per serve as the more complete option.

Are BCAAs vegan?

It depends on the source. The AIS notes BCAAs can be purified from animal sources such as feathers or hair, from plant proteins, or made by fermentation. AminoJect lists fermented amino acids on its label. If this matters to you, check the label or ask the brand about the source.

Do amino acid drinks contain caffeine?

Some do. Optimum Nutrition AMIN.O. Energy has 100 mg of caffeine per serve, while R1 Active BCAA is stimulant-free. Rapid Recovery's ingredient list contains no caffeine. Always check the label if you are sensitive to caffeine or also take a pre-workout.

Which pick suits drug-tested athletes?

Rule One states R1 Active BCAA is Informed Choice certified and regularly tested by the LGC lab. Third-party testing reduces risk but cannot guarantee a product is free of prohibited substances, according to the IOC. Always check with your sport and choose products with current batch testing.
