Katy Dubinsky, PharmD Pharmacist and Founder of PostGigs Expert Commentary on Vitamin B6 Vitamin B6 supports many core processes in the body. It helps produce neurotransmitters, supports immune function, aids in red blood cell formation, and plays an important part in how we break down proteins, carbohydrates, and fats. Because it influences serotonin and dopamine, it also supports mood regulation. Most adults need about 1.3 to 1.7 milligrams of Vitamin B6 daily. Needs increase during pregnancy to support fetal brain development. People most at risk for deficiency include older adults, individuals with alcoholism, those with poor nutrient intake, people with gastrointestinal conditions that affect absorption, and anyone taking medications that interfere with B6 metabolism. Top dietary sources include poultry, fish, chickpeas, potatoes, bananas, and fortified cereals. Consistent intake is important because B6 is involved in many metabolic pathways. Deficiency is not extremely common, but mild deficiencies do occur and can be easy to overlook. Symptoms may include fatigue, irritability, weakened immunity, peripheral neuropathy, and skin changes. Identifying deficiency early is important because long term low levels can affect nerve function and cognition.

Vitamin B6 is one of those micronutrients people usually don't worry much about - but it's undeniably very important. It's involved in more than a hundred enzymatic reactions, from the synthesis of serotonin, dopamine, and GABA to the production of hemoglobin and the support of the immune system. Without it, the body literally loses its ability to "communicate" between cells. The daily requirement for most adults is about 1.3 mg, for older adults 1.5-1.7 mg, and during pregnancy the need rises slightly to 1.9 mg. And although that doesn't sound like much, vitamin B6 deficiency happens more often than we'd like. It's most common among people who either have increased needs or a reduced ability to absorb nutrients. This includes, first and foremost, older adults (since with age, the efficiency of converting vitamin B6 into its active form decreases). Deficiency also occurs in people who abuse alcohol, those with chronic digestive disorders, people after bariatric surgery, individuals with celiac disease or inflammatory bowel conditions. Some medications (isoniazid, hydralazine, penicillamine) as well as certain hormonal contraceptives can also reduce vitamin activity or increase its demand. Deficiency may also appear in people with monotonous diets, those consuming too little protein, and in pregnant or breastfeeding women. The main signs of low B6 levels include fatigue, irritability, dry skin, brittle nails, reduced concentration, and - with long-term deficiency - anemia or tingling in the extremities. Getting vitamin B6 from food is absolutely achievable. The best known sources include poultry, fish, beef liver, chickpeas, potatoes, bananas, avocados, and nuts. But keep in mind that long storage or heat treatment destroys some of it, so it's worth including a variety of B6-rich foods in your diet rather than relying on a single source. If you maintain the recommended level of this vitamin, you'll support not only your energy but also a stable mood, mental clarity, and heart health. By the way, vitamin B6 works together with folate and B12 - and this trio helps keep homocysteine levels in check, which is important for blood vessels and the nervous system. To sum up: this vitamin is essential for maintaining balance in many bodily processes. And the best way to get it is through a normal, varied diet that gives your body everything it needs every day.

Vitamin B6 PLAYS A MAJOR ROLE IN NERVOUS-SYSTEM FUNCTION, RED BLOOD CELL FORMATION, HORMONE REGULATION AND PROTEIN METABOLISM (all things that I see directly impact how wounds heal and how much energy my patients have). Adults around 1.3 - 1.7 mg/day and although that might sound pretty low, it's not difficult to get short-changed if someone isn't eating a diet high in whole foods. People most at risk for deficiency include older adults, individuals with kidney disease, heavy drinkers, and anyone with absorption issues. Some of the BEST DIETARY SOURCES ARE SALMON, CHICKEN, CHICKPEAS, BANANAS AND FORTIFIED CEREALS — all foods I frequently suggest to patients who complain of fatigue or nerve-related symptoms. Most people don't realize what a huge impact B6 has on overall health—IT HELPS REGULATE MOOD, AS WELL AS THE PRODUCTION OF NEUROTRANSMITTERS, AND IT ALSO KEEPS INFLAMMATION UNDER CONTROL. A deficiency is not that common, but when it makes an appearance, it can manifest by way of irritability, brain fog, tingling and numbness in hands or feet, mild anemia, and even a weak immune system. I have had patients think they needed more caffeine when, in fact, they needed better nutrient consumption. It's not about supplements that keep B6 within a healthy range, but feeding it the things it needs to sustain you every day.
Vitamin B6 is one of those quiet heroes that keeps your body humming -- it helps convert the food you eat into energy and supports your mood and immune system. I often tell clients to aim for a variety of whole foods like salmon, bananas, chickpeas, and potatoes to easily meet daily needs (around 1.3 to 1.7 mg for most adults). Deficiency is rare but can show up in people under chronic stress, heavy drinkers, or those on certain medications -- so keeping your diet colourful and whole is the best insurance for balanced energy and vitality.
