If you’re lifting hard and chasing gains, you’ve probably heard about EAAs—essential amino acids. But how many grams do you actually need per day to support muscle growth, recovery, or fat loss?
Let’s skip the fluff. I’ll give you the answer up front, then break it down with examples from real clients I’ve coached.
How Much EAAs Per Day for Lifters?
Most lifters need 10–12 grams of EAAs per day to support recovery and maximize training results.
If you’re in a calorie deficit, training fasted, or pushing higher volume, 12–15g daily can be even more effective.
For general maintenance or lighter training weeks, 7–9g might be enough.
As a coach, I’ve found 10g around the workout window to be the sweet spot for most lifters.

Why EAAs Matter for Weightlifters and Bodybuilders
EAAs are the building blocks your muscles need to grow and repair. They’re especially important when:
- You train fasted
- You’re in a calorie deficit
- Your protein intake is lower than ideal
- You need fast-digesting aminos without a full meal
Personally, I started using EAAs during fasted morning workouts. The difference was clear—less soreness, better pump, and I didn’t feel so drained afterward.
One of my clients, James, was dealing with lingering soreness after leg day. We added 10g of EAAs intra-workout, and within a week, he messaged me:
“Man, I don’t feel like a zombie two days after squats anymore.”

Ideal EAA Dosage Based on Training Goals
Every lifter is different, and I always tailor dosages based on the individual’s goals:
- For muscle growth: 10–12g daily, ideally around your workouts
- For cutting phases: 12–15g to preserve lean mass
- For light training or rest days: 5–7g is usually plenty
- For older lifters or slow recovery: 8–10g can help keep muscle protein synthesis steady
For example, Carlos, a 44-year-old client, was losing muscle during a cut. After adding 10g of EAAs during training, he retained more fullness and felt stronger throughout his sessions.

EAA Timing: When Should You Take Them?
Timing makes a big difference—especially when you’re training fasted or doing intense sessions.
Here’s what I recommend (and personally do):
- Intra-workout: This is my go-to. It hydrates, fuels, and helps reduce muscle breakdown.
- Before fasted cardio: Perfect for early morning sessions.
- Post-workout: Helpful if your next meal is delayed.
- Second dose (optional): Useful for long workouts or two-a-days.
In my case, I sip on 10g of EAAs during training. On push days or long sessions, I might add another 5g post-workout with my whey.

Whole Foods vs Supplements: Do You Really Need EAAs?
You don’t need EAAs if your diet already includes enough high-quality, complete protein.
But let’s be real—most lifters have gaps:
- Some train early and skip breakfast
- Some eat too little protein during a cut
- Some just want something light before training
EAAs aren’t magic, but they fill in the gaps without adding extra calories or digestion time.
One of my vegan clients, Lina, struggled to hit her leucine targets through plant-based meals. EAAs gave her a fast and easy way to support muscle maintenance, especially during busy workdays.

Real Talk from a Coach: What Actually Works
Over the years, I’ve coached all types—hardgainers, older lifters, busy professionals.
One thing’s consistent: when EAAs are used smart, they help you train harder and recover better.
Here’s a quick story:
Nathan, a lean guy training 5x per week, wasn’t recovering well and looked flat by Friday. We added 10g of EAAs during training and another 5g during evening walks.
Within weeks, his pumps lasted longer, energy stayed up, and he was hitting new PRs in deadlifts.
EAAs won’t make up for bad sleep or junk nutrition. But when everything else is dialed in, they’re a powerful tool.
Final Takeaway: Use EAAs Intelligently
If you’re eating well and hitting your protein goals, you might not need EAAs—but they can still give you an edge, especially around your workouts.
Here’s what I recommend:
- Start with 10g during training
- Go up to 15g if you’re training fasted, cutting, or recovering slow
- Don’t rely on them—use them to support your foundation
