Valine: Food Sources & Daily Intake
Valine is one of the three branched-chain amino acids (BCAAs), alongside leucine and isoleucine. Muscle tissue burns and rebuilds the BCAAs directly, so valine plays a hands-on role in muscle growth and repair, energy during exercise, and normal nervous-system function. Because it is essential, the body cannot make it, so it has to come from food. The richest sources are concentrated animal proteins — hard cheeses, meat, fish, eggs — followed by legumes, peanuts and seeds. The table below shows grams of valine per 100 g of food; there is no FDA Daily Value for individual amino acids, so amounts are absolute.

How to Read These Tables
- Essential amino acid. Your body cannot synthesize valine, so a regular dietary supply matters. The nine essential amino acids must come from food; the other eleven the body can build itself.
- Grams per 100 g, not %DV. There is no FDA Daily Value for individual amino acids, so this table reports the absolute grams per 100 g of food and ranks foods by that. A typical serving is shown beside each food.
- Complete vs incomplete protein. Animal foods are “complete” — they carry all the essential amino acids in good proportion. Most single plant foods are lower in one or two; eating a variety of legumes, grains, nuts and seeds across the day covers the gaps.
Recommended Intakes & Upper Limits
Your personal target depends on age, sex and pregnancy. The Daily Value used for the %DV column above is a single label figure; the table below is the age-specific guidance.
| Reference | Adult value | Notes |
|---|---|---|
| Essential? | Yes — essential (a BCAA) | The body cannot make it; it must come from food. |
| Adult requirement | 26 mg/kg/day | WHO/FAO/UNU 2007 estimate. |
| ≈ for a 70 kg adult | ~1.8 g/day | Easily met by a normal protein intake (~0.8 g protein/kg). |
| Main roles | Muscle, energy & nerves | A BCAA burned in muscle for fuel and repair; also supports nervous-system function. |
Bioavailability & Absorption
Valine from food is well absorbed as part of dietary protein. What matters most is total protein quality and quantity: animal proteins (meat, fish, eggs, dairy) are complete and BCAA-dense, while plant proteins are usually a little lower in the branched-chain amino acids and benefit from variety. Spreading protein across meals — roughly 20–40 g of quality protein per meal — is the practical way to keep a steady supply of valine and the other BCAAs available to muscle through the day.
Cooking & Storage
Amino acids are stable to ordinary cooking — valine is not destroyed by normal heat, and cooking actually makes protein easier to digest. Very high, prolonged dry heat (charring) can damage some heat-sensitive amino acids like lysine, but valine is robust. No special handling is needed.
Vegetarian & Vegan Sources
Plant-based eaters can get plenty of valine, but it takes a little planning because plant proteins are less BCAA-dense than animal ones. The strongest plant sources are lentils, white and black beans, chickpeas, peanuts, pumpkin and sunflower seeds, and mushrooms. Eating a variety across the day (legumes + grains + seeds) supplies all the essential amino acids; total protein simply needs to be a bit higher than for omnivores to reach the same valine.
Who Needs to Pay Attention
Outright valine deficiency is rare in anyone eating enough total protein. The groups who should pay attention are those with low overall protein intake — some older adults (who need more protein per kilogram to maintain muscle), people recovering from illness or surgery, and very-low-calorie dieters. The fix is simply adequate quality protein, not isolated valine supplements. People with the rare metabolic disorder maple syrup urine disease cannot break down the branched-chain amino acids normally and must restrict valine, leucine and isoleucine under medical supervision.
