EAAs vs BCAAs — Quick Comparison
| Factor | BCAAs | EAAs |
|---|---|---|
| What are they? | Branched-chain (3 aminos) | Essential (9 aminos) |
| Includes leucine? | Yes | Yes |
| Includes lysine? | No | Yes |
| Complete protein synthesis? | Partial | Complete |
| Best use case | Cheap intra-workout aminos | When dietary protein is low |
| Necessary if eating enough protein? | Usually no | Usually no |
What Are BCAAs?
BCAAs = Branched-Chain Amino Acids: leucine, isoleucine, and valine. The "branched-chain" refers to their molecular structure. They're particularly important for muscle protein synthesis and recovery. BCAAs are essential (your body can't make them), so you must get them from food or supplements.
What Are EAAs?
EAAs = Essential Amino Acids — all 9 essential aminos your body can't synthesize: leucine, isoleucine, valine (the BCAAs), plus lysine, methionine, threonine, tryptophan, phenylalanine, and histidine. EAAs include all BCAAs plus the others your body needs for complete protein synthesis.
The Big Question: Which Should You Take?
Honest answer: probably neither, if you're already eating enough complete protein. Here's why:
- Whey protein, eggs, chicken, fish, beef — all complete proteins containing all 9 EAAs in optimal ratios.
- If you're hitting 0.8-1.0g of complete protein per pound of bodyweight daily, your aminos are already covered.
- Standalone BCAA or EAA supplements are most useful for: fasted training, calorie-restricted cuts where every calorie matters, or those with limited protein intake.
If You Do Want to Supplement
| Product | Brand | Size | Price | Best For |
|---|---|---|---|---|
| Mutant BCAA 9.7 | Mutant | 30 servings | $39.99 | Intra-workout, electrolyte-included |
| PEScience Select Protein | PEScience | 30 servings | $64.99 | Complete EAA via whole protein |
| PEScience Select Vegan Protein | PEScience | varies | $26.99 | Plant-based complete EAA |
Mutant BCAA 9.7 — The Solid BCAA Pick
If you specifically want a BCAA product (e.g., for fasted training where you don't want full protein), Mutant BCAA 9.7 at $39.99 delivers a solid 9.7g leucine-leaning BCAA blend per serving with electrolytes for hydration. Buy: Mutant BCAA 9.7.
The Smart Strategy: Whole Protein Provides Both
For most users, scaling up your whole-protein intake (whey, plant protein, lean meats) provides all the BCAAs and EAAs you need with better total nutritional value. PEScience Select Protein at $64.99 for 30 servings delivers a complete EAA profile per scoop — far more nutritionally complete than a standalone BCAA or EAA supplement.

Frequently Asked Questions
Where can I buy EAAs and BCAAs in Canada?
Top Nutrition & Fitness ships Mutant BCAA 9.7 and other amino acid products to all 10 Canadian provinces. National retailer with same-day shipping, free shipping over $125, and 5% cashback rewards.
What's the difference between EAAs and BCAAs?
BCAAs (branched-chain amino acids) are 3 specific amino acids: leucine, isoleucine, and valine. EAAs (essential amino acids) are all 9 amino acids your body can't make on its own — including the 3 BCAAs plus 6 others (lysine, methionine, threonine, tryptophan, phenylalanine, histidine).
Should I take BCAAs or EAAs?
EAAs are generally more complete because they include all 9 essential amino acids your body needs. BCAAs alone are only useful if you have an EAA-rich diet (e.g., high-protein meals throughout the day). For most active people who already eat enough protein, BCAAs are redundant; EAAs provide more nutritional 'fill-in' value.
Are BCAAs and EAAs necessary if I get enough protein?
If you're getting 0.8-1.0g of complete protein per pound of bodyweight daily through whole foods and protein powder, you're already getting all your BCAAs and EAAs from those sources. Standalone aminos become redundant. They're more useful for people on calorie-restricted diets, fasted training, or who don't get enough whole protein.
Can I mix BCAAs/EAAs with my pre-workout?
Yes — many users add BCAAs or EAAs to their intra-workout drink alongside electrolytes. Mutant BCAA 9.7 can be mixed with water or electrolyte drink during training. Stim-free pre-workouts (like PEScience High Volume) pair well with BCAA/EAA stacks.
How much BCAA/EAA should I take?
Typical doses are 5-10g of BCAAs or 10-15g of EAAs per training session. Most products provide one scoop = standard serving. Don't exceed labeled doses without healthcare provider guidance.
Does Top Nutrition & Fitness ship BCAAs and EAAs to the USA?
Yes — we ship across the entire United States with no duties or tariffs.
