Water-soluble B vitamins are easily flushed out of your body, which, luckily, makes it difficult for toxic levels to accumulate. Read below to find out which water-soluble B vitamin can become toxic, and at what dosage it can cause adverse events …
Vitamin B6 is one of the 13 essential vitamins you need in your diet because your body cannot make enough on its own.
Like all B vitamins, vitamin B6 is water-soluble so it dissolves in water. This dissolution allows your body to easily flush out any excess instead of storing it in your liver or fat tissue.
As vitamin B6 is mostly found in animal food sources, it is recommended for vegans or vegetarians to eat higher levels of vitamin B6-fortified cereals or to use a nutritional supplement. Supplementing your diet with vitamin B6 using MICROGEL™ technology is best for optimal absorption. This delivery system allows you to fully absorb nutrients into your bloodstream and then into your cells, where they work to improve health.
Vitamin B6 is a generic label for different compounds:
Everyone is different, and certain factors such as your age, sex, or health will affect your unique nutritional needs. To provide a general guide, the Food and Nutrition Board (FNB) establish the Recommended Dietary Allowance (RDA) to meet the needs of most healthy individuals. The RDA for vitamin B6 in both men and women range:
• Infants (0 – 12 months): 0.1 – 0.3 mg/day AI
• Children (1 – 8 years): 0.5 – 0.6 mg/day
• Adolescents (9 – 18 years): 1 – 1.3 mg/day
• Adults (19+ years): 1.3 – 1.7 mg/day
• Pregnant and nursing women: 1.9 – 2 mg/day
If you have a preexisting health condition, concern, or take prescription medication, it’s important to talk with your doctor or registered dietitian about your nutrition, especially when choosing which supplements and dosages are optimal for your health.
Although your body can easily flush out B vitamins, vitamin B6 in the pyridoxal phosphate form has the potential to be toxic because it is stored in your muscles and liver. Toxicity is typically seen when taking doses of 1–6 grams a day for over a year. Symptoms of toxicity include numbness in extremities, trouble walking, and other neurological issues. A tolerable upper intake level (UL) has been established to prevent adverse reactions.
• Infants (0 – 12 months): – mg/day
• Children (1 – 8 years): 30 – 40 mg/day
• Adolescents (9 – 18 years): 60 – 80 mg/day
• Adults (19+ years): 100 mg/day
Anyone who is under the care of a physician and uses vitamin B6 for a medical reason is excluded from the UL.
Vitamin B6 deficiency is uncommon and would most likely be accompanied by other nutrient deficiencies such as vitamin B12 and folate. Those who have impaired metabolism, eat a vegetarian or vegan diet, who are undernourished, suffer from alcoholism, have poor renal function, or who are diagnosed with autoimmune disorders are at risk for deficiency.
Symptoms of vitamin B6 deficiency include:
