Description

Essential amino acids are the nine amino acids the human body requires but cannot synthesize on its own. They must come from food or supplementation. While BCAAs (leucine, isoleucine, and valine) get most of the attention in the performance category, the full picture of muscle maintenance, recovery, and protein metabolism depends on all nine EAAs working together.*

Double Wood's Essential Amino Acids formula delivers all nine in free form, meaning they are readily available for use without the digestion step required for whole proteins or larger peptides. This makes them a practical and efficient option for use around training, whether before, during, or after exercise.*

Each bottle contains 225 capsules, providing 75 servings at the standard 3-capsule daily serving. Take on an empty stomach, with room to take additional servings around training up to the labeled maximum of 12 capsules per day, giving flexibility across different training volumes and body weights. If sensitive, take with water and/or a small amount of food.

Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. For a more complete performance and recovery regimen, EAAs pair naturally with Creatine to support energy availability during training, or with Collagen to support broader connective tissue and joint function in an active lifestyle.*

All 9 EAAs in one capsule. Soy-Free, Gluten-Free, Non-GMO.

Essential Amino Acids

This supplement provides all nine essential amino acids: L-Leucine, L-Lysine, L-Threonine, L-Valine, L-Isoleucine, L-Phenylalanine, L-Histidine, L-Tryptophan, and L-Methionine. These amino acids cannot be produced by the human body and must be obtained from dietary sources, making them fundamental building blocks of protein. They have been valued in nutrition for their role in supporting muscle protein synthesis, recovery, and balanced metabolic processes. Supplementation offers a convenient way to ensure a complete profile of these core nutrients for daily wellness.

Frequently Asked Questions

What are essential amino acids?

Essential amino acids (EAAs) are the 9 amino acids your body can't produce on its own and must obtain from food or supplementation. They are L-Leucine, L-Lysine, L-Threonine, L-Valine, L-Isoleucine, L-Phenylalanine, L-Histidine, L-Tryptophan, and L-Methionine. EAAs are the building blocks of every protein in the body and are directly involved in muscle protein synthesis, hormone production, and tissue repair.

What's the difference between EAA and BCAA?

BCAAs are 3 of the 9 EAAs — L-Leucine, L-Isoleucine, and L-Valine. EAA supplements contain all 9 essential amino acids; BCAA supplements contain only those 3. Both can support recovery, but only a complete EAA profile provides every amino acid required to fully complete muscle protein synthesis. An EAA supplement covers what a BCAA supplement does, and more.

When should I take EAA capsules?

There's no single best time. Many people take EAAs around training to support recovery, on lower-protein days to fill amino acid gaps, or during fasted or calorie-restricted periods to maintain a complete amino acid profile. Double Wood's recommended dosage is 3 to 10 capsules per day, depending on protein intake from food. Do not exceed 12 capsules per day.

Can I take EAA capsules with protein powder?

Yes. EAA capsules and protein powder serve overlapping but distinct purposes. Protein powder delivers a larger dose of complete protein with calories; EAA capsules deliver a focused, low-calorie dose of just the 9 essential amino acids. Many people use EAA capsules between meals or during fasted training when a full protein shake isn't preferred.

Are these EAA capsules third-party tested?

Yes. Every batch of Double Wood's Essential Amino Acid capsules is independently third-party tested for purity and potency. Certificates of Analysis and lab results are linked directly on this product page. The product is manufactured in a GMP-certified facility in the USA.

Great sleeping aid for me.

"I started taking these at bedtime and my sleep has drastically improved. I go to sleep quickly and sleep soundly all night long. I rarely have done that. It usually takes forever for me to go to sleep and then I don’t sleep well and wake up tired. I don’t know what would happen if I took them in the day time."
