You’re tired. Not just "stayed up too late watching Netflix" tired, but that deep, cellular fatigue that a third espresso can’t touch. Most people assume it’s iron. Or maybe they think they need more sleep. Honestly, it might just be a lack of foods high in vit b6. This vitamin—formally known as pyridoxine—is the ultimate multitasker in your body, yet it gets almost zero credit compared to its flashy cousins like Vitamin C or B12. It’s involved in over 100 enzyme reactions. Think about that for a second. Without enough B6, your brain doesn't make neurotransmitters like serotonin and dopamine correctly. Your mood dips. Your energy tanks. You basically start running on low-battery mode.
Most of us think we're getting enough because we eat "balanced" diets. But here’s the kicker: B6 is fragile. It’s sensitive to heat and processing. If you’re relying on boxed cereals or overly cooked convenience meals, you’re likely getting a synthetic version that doesn't always hit the same way as the real deal found in whole foods.
The Heavy Hitters You’re Likely Ignoring
When people talk about foods high in vit b6, they usually point to bananas. Sure, bananas are fine. They’ve got about 0.4mg per medium fruit, which is roughly 25% of your daily value. But if you really want to move the needle, you’ve got to look at chickpeas. One cup of canned chickpeas packs a massive 1.1mg of B6. That’s more than half of what most adults need in a single day. It’s basically a cheat code for your nervous system. You can toss them in a salad, mash them into hummus, or roast them until they’re crunchy.
Then there’s beef liver. Look, I know it's not the trendiest food on Instagram. Nobody is rushing to post their liver and onions, but from a purely biological standpoint, it is a powerhouse. A 3-ounce serving gives you nearly 1mg of B6. It’s also loaded with B12 and Vitamin A, making it a "superfood" long before that term was hijacked by marketing departments for kale chips.
Fish Isn't Just for Omega-3s
We always hear about salmon for its healthy fats. That's great, but it’s also one of the premier foods high in vit b6. Sockeye salmon, specifically, is a beast in this category. A standard fillet provides about 0.6mg. Yellowfin tuna is even higher, often hitting 0.9mg per serving.

The interesting thing about fish sources is the bioavailability. Because you aren't typically boiling tuna for six hours, the B6 stays relatively intact. If you’re searing a piece of tuna, you’re getting a much more potent dose than you would from a highly processed granola bar that claims to be "fortified."
The Starchy Reality of Potatoes and Poultry
Don't sleep on the humble potato. Seriously. A large baked potato (with the skin!) is surprisingly rich in pyridoxine. It offers about 0.4mg to 0.5mg. If you’re a fan of sweet potatoes, you’re getting a decent hit too, though slightly less than the white varieties.
Poultry is the reliable workhorse here. Chicken and turkey are staples for a reason. A breast of chicken delivers roughly 0.5mg. It’s consistent. It’s easy. It’s why people on high-protein diets often accidentally hit their B6 targets without even trying. Turkey is similar, though it’s a bit of a myth that the B6 or tryptophan in turkey is what makes you sleepy after Thanksgiving—that’s usually just the three servings of stuffing.
Why Your Brain Actually Cares
Why does any of this matter? It’s not just about avoiding a deficiency. It’s about optimization.

The National Institutes of Health (NIH) has highlighted that B6 helps maintain normal levels of homocysteine, an amino acid in your blood. High levels of homocysteine are linked to heart issues and cognitive decline. Research published in the Journal of Nutrition has explored how B6, alongside B12 and folate, might play a role in slowing down brain atrophy in older adults. It's essentially structural support for your grey matter.
If you're feeling "brain fog," it might not be the weather. It could be that your neurotransmitter synthesis is lagging because the raw materials—the B6 from your lunch—aren't there.
The Bioavailability Trap
Here is where it gets complicated. Not all foods high in vit b6 are created equal in the eyes of your gut. Plants contain a form called pyridoxine glucoside. This version is sometimes harder for the body to absorb compared to the forms found in animal products (pyridoxal and pyridoxamine).
If you are strictly plant-based, you have to be more intentional. You can’t just eat one banana and call it a day. You need the chickpeas, the sunflower seeds, and the spinach. Spinach is a "sorta" high source—it has it, but you have to eat a fair amount of it to make a dent.

- Pistachios: These are a secret weapon. One ounce gives you 25% of your DV.
- Sunflower Seeds: Great for snacking, offering about 0.2mg per ounce.
- Carrot Juice: Surprisingly, a cup of carrot juice is much more concentrated in B6 than eating a raw carrot.
Things That Kill Your B6 Levels
You could be eating all the right foods high in vit b6 and still run low. Alcohol is the main culprit here. It produces acetaldehyde, which actually competes with the active form of B6 in your body and can even "shoo" it off the enzymes where it’s supposed to be working.
Chronic inflammation also eats up your B6 stores. If you’re dealing with an autoimmune condition or even just high levels of stress, your body’s demand for B6 goes through the roof. This is why some doctors, like those at the Mayo Clinic, occasionally look at B6 levels when patients complain of unexplained nerve pain or "pins and needles" sensations (peripheral neuropathy).
Practical Steps for Your Next Meal
Getting your levels right doesn't require a radical lifestyle overhaul. It just requires a bit of strategy at the grocery store.
- Stop peeling everything. A lot of the nutrients in tubers like potatoes are in or right under the skin.
- Add nutritional yeast. If you’re vegan, this stuff is gold. Two tablespoons can provide a massive dose of B-vitamins, including B6, and it tastes like parmesan cheese.
- Watch the heat. Try steaming or sautéing your veggies instead of boiling them to death. Water-soluble vitamins like B6 will literally leak out into the boiling water, which you then pour down the drain.
- Rotate your proteins. If you usually eat chicken, swap it for salmon or even a lean cut of beef once or twice a week.
If you’re over 50, pay closer attention. The RDA (Recommended Dietary Allowance) actually increases as you age because the body becomes less efficient at absorbing it. For men over 50, it’s about 1.7mg, and for women, it’s 1.5mg. Younger adults generally need about 1.3mg. It’s a small amount, but the gap between feeling "okay" and feeling "great" often lives in those tiny milligram differences.
Start by adding one "power source" to your day. Toss a handful of chickpeas into your lunch. Grab a bag of pistachios instead of chips. Your brain—and your energy levels—will likely notice the difference faster than you think.
