Recommended Daily Intakes of Vitamin B6
The daily intake of vitamin B6 depends on age and gender. Men and women aged 14 to 50 need 1.3 mg per day. For those over 51, men require 1.7 mg daily, while women need 1.5 mg each day.
Children over four and adults should aim for a Daily Value (DV) of 1.7 mg according to U.S guidelines. The tolerable upper limit (UL) is set at 100 mg per day for adults in the U.S., but as of 2023, Europe recommends staying below 12 mg daily to avoid risks like nerve damage or sensory changes.
Key Benefits of Vitamin B6
Vitamin B6 affects many parts of the body, including your mood, brain, and blood health. It plays a big role in keeping you healthy by helping with energy use and reducing certain risks.
Enhances Mood and Reduces Depression Symptoms
High doses of Vitamin B6 help reduce stress, anxiety, and depression symptoms. It plays a key role in producing serotonin and GABA—chemical messengers that regulate mood. These neurotransmitters create calmness and improve mental health.
A study with 478 people showed reduced stress levels after taking Vitamin B6 compared to a placebo group. Combining magnesium with this nutrient further boosts activity while lowering stress.
This powerful duo supports emotional well-being effectively.
Supports Brain Health and Cognitive Function
Vitamin B6 helps the brain make neurotransmitters, which send messages in the body. These are key for memory, learning, and mood stability. Low levels of this vitamin can cause confusion or depression.
Older adults with higher Vitamin B6 levels show better memory performance.
This nutrient keeps homocysteine balanced in your blood. High homocysteine levels may harm brain function and link to cognitive decline or Alzheimer’s disease. Eating foods rich in Vitamin B6, like bananas and spinach, supports long-term brain health.
“Vitamin B6 is vital not just for physical health but also mental clarity and sharpness.”
Aids in Hemoglobin Production and Prevents Anemia
Helps your body make hemoglobin, which carries oxygen in red blood cells. Low levels of this nutrient can lead to microcytic anemia, causing fatigue and weakness. Pregnant women are at higher risk of anemia if they lack vitamin B6.
A study showed daily 75 mg supplements improved symptoms in pregnant women with anemia. Foods like beef liver and fortified cereals help provide the needed intake for healthy red blood cell production.
Alleviates Symptoms of Premenstrual Syndrome (PMS)
Vitamin B6 can ease PMS symptoms like mood swings, depression, and irritability. Studies suggest doses up to 100 mg per day may show results for treatment. It helps by balancing neurotransmitters in the brain, which regulate emotions.
Combining Vitamin B6 with zinc strengthens its benefits for PMS relief. Many women report fewer cramps and better moods after using these nutrients together. Always check with a doctor before starting new supplementation.
Reduces Nausea During Pregnancy
Easing premenstrual symptoms links closely to managing pregnancy challenges. Many pregnant women face nausea, especially during the first trimester. Taking 25 mg of Vitamin B6 every eight hours has been shown to cut down morning sickness and vomiting effectively.
Studies report a major drop in nausea scores after therapy.
Combining Vitamin B6 with doxylamine improves results even further—reducing symptoms by up to 70%. The American College of Obstetricians and Gynecologists (ACOG) recommends doses ranging from 10–25 mg, taken three or four times daily, for relief.
This water-soluble vitamin offers a safe option for managing discomfort without harming the baby.
Lowers Risk of Heart Disease by Preventing Clogged Arteries
Vitamin B6 helps lower homocysteine levels in the blood. High homocysteine can lead to clogged arteries, increasing heart disease risk. Studies show people with low Vitamin B6 are nearly twice as likely to develop heart issues.
A combination of Vitamin B6 and folic acid has shown positive effects on heart health. It reduces abnormal heart test results and supports better blood flow by preventing clots from forming.
Adequate intake is key for maintaining a healthy cardiovascular system.
May Help Prevent Certain Types of Cancer
Higher plasma PLP levels, a marker of vitamin B6, are linked to a 30%-50% lower risk of colorectal cancer. Studies show that people with low B6 status often face increased inflammation.
Chronic inflammation can raise the chance of developing certain cancers.
A meta-analysis confirmed higher PLP levels reduce colorectal cancer risk. Genetic factors and poor diets may weaken this protective effect. Eating foods rich in vitamin B6 or taking supplements could help maintain healthy PLP levels.
Promotes Eye Health and Prevents Eye Diseases
Vitamin B6 helps protect your eyes. Studies show consuming more than 2.34 mg daily can lower glaucoma risk by 75%. This vitamin has strong antioxidant properties that fight damage to eye cells.
It may also reduce the risk of age-related macular degeneration (AMD). AMD is a common cause of vision loss in older adults. Including foods rich in Vitamin B6, like bananas and fortified cereals, supports long-term eye health.
Reduces Inflammation in Conditions like Rheumatoid Arthritis
Healthy eyes need proper care… but reducing inflammation also matters, especially for chronic conditions like rheumatoid arthritis (RA). Studies show that Vitamin B6 helps lower inflammation in RA patients.
In one trial with 35 individuals, the experimental group took 100 mg/day of B6 along with 5 mg/day of folic acid.
The results were clear. Levels of pro-inflammatory markers like IL-6 and TNF-alpha dropped significantly in this group. This reduction can ease joint swelling and pain caused by RA.
Adding more B vitamins to your diet may support overall health while managing inflammatory conditions better.

Cancer treatments such as Altrethamine may lose effectiveness when mixed with this vitamin. Always consult your doctor before taking supplements—especially if you’re on prescription medication.
Groups at Risk of Vitamin B6 Deficiency
Certain health conditions can make people more prone to vitamin B6 deficiency. Lifestyle factors, such as poor diet or excessive alcohol use, may also increase the risk.
Individuals with Impaired Renal Function
People with chronic renal insufficiency or on dialysis often face vitamin B6 deficiency. The kidneys play a key role in processing this water-soluble vitamin, but damaged kidneys struggle to do so.
This increases the risk of health problems like microcytic anemia, skin rashes (dermatitis), and depression due to low levels.
Impaired immune function is another concern among these individuals. A weakened system may make it harder to fight infections. Regular monitoring and possible supplementation of vitamin B6 can help prevent complications linked to its deficiency in such cases.
Those with Autoimmune Disorders
Autoimmune disorders can make it harder for the body to absorb vitamin B6. This can lead to a deficiency over time. Symptoms such as confusion, depression, and fatigue may appear if levels drop too low.
A weakened immune system is another common issue linked to these conditions.
Rheumatoid arthritis and ulcerative colitis are examples of autoimmune diseases that may increase this risk. Ensuring proper intake through diet or supplements helps maintain brain health, mood balance, and energy levels.
People with Alcohol Dependence
People with alcohol dependence often lack vitamin B6. Alcohol affects how the body absorbs and uses this water-soluble vitamin. Over time, it can lead to a deficiency.
This deficiency increases the risk of anemia, depression, and confusion. A weakened immune system is another common problem. Lower energy levels may also occur due to poor protein metabolism.
Moving forward, other groups are also at risk of vitamin B6 deficiency….
