Valine
An essential branched-chain amino acid (BCAA) that promotes muscle growth and repair.
Also known as: L-Valine
Overview
Valine is one of the three branched-chain amino acids (BCAAs), essential for muscle protein synthesis, tissue regeneration, and energy production. It works in conjunction with leucine and isoleucine to support muscle health and athletic performance. Valine is also involved in nitrogen balance and cognitive function.
Key Benefits
Stimulates Muscle Growth
Valine plays a crucial role in muscle protein synthesis, the process of building new muscle tissue.
Enhances Tissue Repair
It aids in the repair of damaged tissues, including muscles, making it beneficial for post-workout recovery.
Provides Energy
Valine can be used as an energy source by muscles during exercise, sparing other energy stores.
Maintains Nitrogen Balance
Valine is important for maintaining a positive nitrogen balance, which is essential for muscle growth and preventing muscle breakdown.
Dosage & How to Take
Valine is commonly taken as part of a BCAA supplement, with a typical ratio of 2:1:1 (Leucine:Isoleucine:Valine). The dosage can be adjusted based on individual goals and activity levels.
| Purpose | Dose | Notes |
|---|---|---|
| General Health | 1-2 grams per day | Can be obtained through a protein-rich diet. |
| Athletic Performance | 5-10 grams per day | Often taken as part of a BCAA supplement around workouts. |
Best Time to Take
For optimal results, consume Valine during or after your workout.
With or Without Food
Can be taken with or without food.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| L-Valine | High | General supplementation | The most common and well-researched form. |
| BCAA Complex | High | Athletic performance | Provides a balanced ratio of Isoleucine, Leucine, and Valine. |
Side Effects & Safety
Common
- Nausea

Interactions
Competes for absorption, so it's best to take them in a balanced ratio.
May enhance the effects of medications that lower blood sugar.
