Amino acids are the building blocks of protein. They matter because your body needs the full set of essential amino acids (EAAs) to build and repair muscle tissue. That’s why EAA formulas are popular around training and between meals, especially when you want something lighter than a shake.
This range covers three main use cases: full-spectrum EAAs for training and recovery support, amino blends with added energy when you want more “pick me up” feeling, and standalone glutamine for people who like to keep things simple.
Who amino acids suit
- Anyone training hard who wants an easy intra-workout drink or something light post-session.
- People who struggle to hit protein targets consistently and want extra support between meals.
- Anyone who doesn’t fancy a heavy shake but still wants a functional, low-calorie option.
- Those on lower-protein or plant-heavy diets who want a straightforward way to top up essential amino intake.
EAA vs BCAA
EAAs are the full set of nine essential amino acids your body can’t make itself. They’re the complete “building materials” needed to support muscle protein synthesis.
BCAAs are three of those nine (leucine, isoleucine, valine). They can help trigger the muscle-building signal, but on their own they don’t provide the full set of essential amino acids needed for a maximal response. If you’re choosing one, EAAs are usually the better all-rounder.
When to use amino acids
During training: ideal if you want something refreshing to sip through a session, especially on higher-volume days.
Between meals: useful if there’s a long gap between meals and you want something light that still feels “on plan”.
Post-workout: works well if you can’t eat straight away or you want something quicker than a full meal.
Low-appetite days: an easy way to stay consistent when food intake dips.
Amino acids benefits
Supports muscle protein synthesis
EAAs are the key amino acids required to stimulate muscle protein synthesis. If you’re training regularly, they’re a practical add-on around sessions when you want amino support without extra calories or a heavy shake.
Light, easy to drink, and easy to repeat
Most amino drinks are simple to mix and easy to get down, which is the whole point. Consistency beats perfect timing.
Useful when a full shake isn’t happening
Protein powders are still the main foundation, but amino drinks are handy when you want something lighter, or when you’re out and about and food timing is messy.
Which Per4m option should you choose?

Glutamine is a clean, unflavoured option when you want a single-ingredient amino you can add to water, juice, or your usual shake. A standard serving is 5g.
Popular picks
Best all-rounder: EAA Xtra if you want full-spectrum essential amino support with a great taste and zero sugar.
Best for training energy: Amino Burn when you want amino support plus a caffeinated boost.
Best add-on: Glutamine if you prefer single-ingredient simplicity.
FAQs
Do I need amino acids if I already use protein powder?
If you consistently hit your daily protein target, you might not “need” them. Amino drinks are most useful for convenience: during sessions, between meals, or when you want something lighter than a shake.
Are EAAs better than BCAAs?
For most people, yes. BCAAs are only three essential amino acids. EAAs provide the full set your body needs for a maximal muscle protein synthesis response.
Can I sip EAAs during a workout?
Yes. That’s one of the most common ways to use them, especially for longer sessions or higher-volume training blocks.
Will amino acids break a fast?
If you’re fasting strictly for metabolic reasons, amino acids are still nutrients and can count as breaking a fast. If you’re fasting mainly for appetite control, many people still use amino drinks during training because they’re low calorie. Your goal decides the rule.
Can I stack amino acids with creatine?
Yes. Creatine is a daily consistency supplement, and it stacks easily with amino drinks, hydration products, and protein powders.
Any caffeine note for Amino Burn?
It contains caffeine, so if you’re sensitive or training late, be smart with timing and total daily intake. If you’re pregnant, breastfeeding, under 18, or have a medical condition, check the label guidance and speak to a healthcare professional first.
Food supplements should be used alongside a varied, balanced diet and healthy lifestyle.
