- Methionine is an essential amino, and arguably the toughest one to get on a vegan diet other than lysine.
- You should aim for about 14 mg per kg of bodyweight per day (or 6.4 mg per lb).
- The best vegan sources of methionine are vital wheat gluten and mostly seeds.
Methionine is super common in animal products (most meats), but not too common in plants.
It can lead to issues like hair loss if you’re not getting enough.
So, I compiled all the best food sources of methionine to help you plan your diet and get a bit extra if you’re worried about it.

How Much Methionine Do You Need?
Methionine is important for protein synthesis, but also liver function.
With a methionine deficiency, you’re at risk for:
- Abnormal liver function, leading to upregulated proinflammatory genes
- Hair loss
- Poor skin tone
- Neural tube defects (for pregnant women).
To avoid any risk, you’ll want to meet the RDA for methionine of 14 mg per kg of bodyweight per day.
For someone weighing 70 kg (154 lbs), that’s about 1.1 grams per day.
I highly recommend tracking what you eat for a few days using a free tool like Cronometer to see if you’re getting enough.
It’s not that hard if you eat the right foods.
The Best Overall Plant-Based Sources of Methionine
We’ll look at lists of the best vegan sources of leucine per serving and per 100 calories in just a minute.
But first, I wanted to identify the most efficient sources of methionine. By efficient, I mean that a food has a lot of methionine per 100 calories, and per serving.
So, I created the bubble chart below (click to enlarge). The most efficient sources tend towards the top and right of the chart.
There’s a whole cluster of beans and a few other foods near the bottom left. Those are okay sources of methionine, but not the very best.
If you’re looking to realistically get methionine as easily as possible, focus on the 6 foods that stand out from the pack:
- Vital wheat gluten
- Brazil nuts
- Hemp seeds
- Sesame seeds
- Sunflower seeds
The Best Vegan Sources of Methionine Per Serving and Calorie
I pulled all this data straight from the USDA food database.
It’s sorted by the amount of methionine in a typical serving, which makes it a lot more realistic (1.5 servings of brazil nuts, versus 25 cups of water spinach).
|Food||Serving||Energy (kcal)||Methionine (g)||Methionine (g) per 100 Calories|
|Vital wheat gluten||100 g||370||0.98||0.26|
|Brazil nut||0.5 cup||438||0.75||0.17|
|Sesame seeds||0.5 cup||413||0.42||0.10|
|Hemp seeds||3 tbsp||166||0.28||0.17|
|Pumpkin seeds||1 cup||285||0.27||0.09|
|Rye grain||1 cup||571||0.26||0.05|
|Buckwheat groats||1 cup||567||0.25||0.04|
|Kidney beans||1 cup||225||0.23||0.10|
|Black beans||1 cup||227||0.23||0.10|
|Pistachio nuts||0.5 cup||344||0.22||0.06|
|Navy beans||1 cup||255||0.20||0.08|
|Adzuki beans||1 cup||294||0.18||0.06|
|Chia seeds||3 tbsp||146||0.18||0.12|
|Pine nuts||0.5 cup||454||0.18||0.04|
|Mung bean||1 cup||212||0.17||0.08|
|Lima beans||1 cup||209||0.12||0.06|
|Fava bean||1 cup||187||0.11||0.06|
Four types of foods dominate the top results:
- Vital wheat gluten – While you don’t eat vital wheat gluten by itself so it’s not the most fair comparison, seitan is still mostly made of vital wheat gluten and has a ton of methionine.
- Nuts/seeds – Brazil nuts are the #2 source of methionine, but lots of seeds are close behind (pumpkin, sesame, hemp). Even though nuts have an amino acid profile relatively low in methionine, the raw amount is still decent.
- Beans – All common types of beans have a decent amount of methionine in them (kidney, black, navy, adzuki, mung).
- Grains – Certain grains, like oats, rye, and quinoa all have a good amount of methionine.
The Top Methionine Vegan Foods Per 100 Grams
The “standard” way to compare food nutrition is per 100 grams, not per serving (even though I feel like that’s more useful).
So in the sake of completeness, let’s also look at the best sources of methionine per 100 grams.
|Food||Methionine (g) Per 100 grams|
|Vital wheat gluten||0.98|
Vital wheat gluten is still near the top, as are nuts, seeds, and beans.
If we extended this list to the top 50 or so, you’d start to see some leafy greens (e.g. spinach has 0.05), but it’s hard to eat a lot of those.
Vegan Recipes That Are High in Methionine
The lists above will give a good starting point to explore from.
I’ve also gathered some vegan recipes high recipes high in methionine that you might be interested in.
In general, the best foods from the lists go well in recipes like:
- Noodle recipes (with seeds on top)
- Salads (with seeds on top)
- Porridge and oatmeal
