Blackberries are moderate in arginine, so they’re not a high-arginine food, but they do contain a decent amount of this amino acid compared to many other fruits.
If you’ve been wondering are blackberries high in arginine, the short answer is no, they’re not loaded with it, but they’re not devoid of it either.
A cup of raw blackberries gives you roughly 40–50 mg of arginine, which is a modest amount.
This makes blackberries a mild contributor to your daily arginine intake rather than a major source.
In this post, we’ll look at whether blackberries are high in arginine, how much arginine blackberries actually have, and how they compare to other foods.
Let’s get into it.
Are Blackberries High in Arginine?
Blackberries are not high in arginine.
They contain some arginine, but the amount is small when you compare it to protein-rich foods like meat, dairy, nuts, and seeds.
So if you’re specifically looking to boost arginine intake, blackberries alone won’t get you there.
Here’s why blackberries don’t qualify as a high-arginine food:
1. Arginine Content in Blackberries Is Low Per Serving
One cup of fresh blackberries contains only about 40–50 milligrams of arginine.
That’s a tiny fraction of what you’d get from a handful of pumpkin seeds or a piece of chicken.
For context, a single ounce of pumpkin seeds can deliver over 1,000 mg of arginine.
So blackberries are clearly not a high-arginine fruit.
2. Blackberries Are Mostly Water and Fiber
Blackberries are made up mostly of water, fiber, and carbohydrates.
They’re low in protein, and arginine is an amino acid that comes packaged with protein.
Since blackberries don’t have much protein, they naturally don’t have much arginine.
That’s the simple reason blackberries aren’t high in arginine.
3. Other Fruits Have Similar or Higher Arginine
Blackberries aren’t unique in their arginine content.
Fruits like bananas, grapes, and berries in general have comparable low levels.
Some fruits like watermelon actually contain more citrulline, which the body converts into arginine.
So if you’re after arginine from fruit, watermelon might be a better bet than blackberries.
How Much Arginine Do Blackberries Have?
Blackberries have a small but measurable amount of arginine.
Here’s a closer look at the numbers so you can see exactly where blackberries stand.
1. Arginine Per Cup of Blackberries
One cup of raw blackberries (about 144 grams) provides roughly 40–50 mg of arginine.
That’s about 0.04–0.05 grams.
To put that in perspective, the average adult needs around 3–6 grams of arginine per day from diet and internal synthesis.
So a cup of blackberries gives you less than 2% of that.
2. Arginine Per 100 Grams of Blackberries
Per 100 grams, blackberries contain around 30–35 mg of arginine.
Again, that’s a very small amount.
For comparison, 100 grams of chicken breast has over 1,400 mg of arginine.
So blackberries are not even in the same league as high-arginine foods.
3. Arginine in Dried Blackberries
Dried blackberries are more concentrated, so they’ll have more arginine per gram.
But even then, the amount is still modest because drying removes water, not protein.
You’d need to eat a lot of dried blackberries to get a meaningful dose of arginine.
And that would come with a lot of sugar, so it’s not ideal.
Blackberries vs Other Foods for Arginine
Blackberries are not a high-arginine food when you stack them against other options.
Let’s see how they compare.
1. Nuts and Seeds Are Much Higher
Pumpkin seeds, almonds, walnuts, and peanuts are all rich in arginine.
A single ounce of pumpkin seeds can have over 1,000 mg.
Blackberries have about 40–50 mg per cup.
So nuts and seeds are far better if arginine is your goal.
2. Meat and Dairy Are Also High
Chicken, turkey, beef, eggs, and dairy products are all high in arginine.
They’re complete proteins, so they contain all essential and non-essential amino acids, including arginine.
Blackberries can’t compete with that.
3. Some Fruits Beat Blackberries Too
Watermelon, for example, is known for its citrulline content, which converts to arginine.
Other fruits like bananas and avocados have slightly more arginine than blackberries.
So even among fruits, blackberries aren’t the top choice for arginine.
So, Are Blackberries High in Arginine?
Blackberries are not high in arginine.
They contain a small amount, but they’re not a significant source compared to nuts, seeds, meat, or dairy.
If you’re asking are blackberries high in arginine because you want to increase your intake, you’re better off with other foods.
Blackberries are still a healthy fruit with fiber, vitamin C, and antioxidants.
They just aren’t a high-arginine food.
So enjoy blackberries for what they are, but don’t rely on them for arginine.
