Vitamin B6 May Help Morning Sickness

What Is Vitamin B6? | Vitamins

During pregnancy, anyone experiencing morning sickness is often prescribed a combination tablet of doxylamine an antihistamine and vitamin B6.

Vitamin B6 has been shown to help with nausea while the doxylamine may reduce vomiting. A typical dose of the combination tablet is 10 mg to 25 mg, three times a day.

Tiredness And Low Energy

A vitamin B6 deficiency can leave you feeling unusually tired and sluggish.

A big reason is vitamin B6s role in helping make hemoglobin. Thats the protein in your red blood cells that helps carry oxygen throughout your body.

If your cells dont get enough oxygen as a result of too little hemoglobin, its called anemia. That can make you feel tired and weak.

There have been select cases of B6-related anemia in which taking the inactive pyridoxine hydrochloride form of the vitamin didnt help. However, supplementing with the bodys most active form of B6, called pyridoxal 5-phosphate , resolved the anemia (

27 ).

Nerve problems from B6 deficiency are reversible with adequate B6 intake. On the other hand, nerve problems from B6 toxicity may be more difficult to treat.

Summary Burning, shooting pains in your limbs, hands and feet can be caused by nerve damage from B6 deficiency or overdose.

What Happens If I Consume Too Much Vitamin B6

Taking more than 200mg a day of vitamin B6 for long periods is known to trigger peripheral neuropathy. This can be permanent, so make sure you never consume too much.16

High doses of vitamin B6 can also cause sores on the skin, sensitivity to sunlight, and digestive troubles, including heartburn and nausea.17

What Happens If I Take Too Much Vitamin B6

When taking a supplement, it’s important not to take too much.

Taking 200mg or more a day of vitamin B6 can lead to a loss of feeling in the arms and legs known as peripheral neuropathy.

This will usually improve once you stop taking the supplements.

But in a few cases when people have taken large amounts of vitamin B6, particularly for more than a few months, the effect can be permanent.

The effect of taking vitamin B6 at doses between 10 and 200 mg is unclear. So there’s not enough evidence to say how long these doses could be taken for safely.

Cracked And Sore Lips

Cheilosis, which is characterized by sore, red and swollen lips with cracked mouth corners, can result from B6 deficiency. Cracked areas may bleed and become infected.

In addition to being very painful, having cracked and sore lips can make activities like eating and talking difficult.

Correcting B6 deficiency with foods rich in the vitamin or a supplement may clear up these symptoms.

Notably, deficiencies of riboflavin, folate, iron and other nutrients can also cause this condition, as can sunny, dry or windy weather and other external factors .

Summary Sore lips with cracks in the corners of your mouth can be a sign of B6 deficiency. If thats the case, getting enough B6 through food or a supplement could heal your lips.

If You’re Pregnant Or Could Get Pregnant

If you’re pregnant, trying for a baby, or could get pregnant, it’s recommended that you take a 400 microgram folic acid supplement daily until you’re 12 weeks pregnant.

Folic acid supplements need to be taken before you get pregnant, so start taking them before you stop using contraception or if there’s a chance you might get pregnant.

This is to help prevent neural tube defects, such as spina bifida, in your baby.

Some women have an increased risk of having a pregnancy affected by a neural tube defect and are advised to take a higher dose of 5mg of folic acid each day until they’re 12 weeks pregnant.

This is important and unlikely to cause harm, as it’s taken on a short-term basis, but speak to your doctor first.

Get more advice about vitamins and minerals during pregnancy, including who should take a higher dose of folic acid.

Vitamin B6 Toxicity Symptoms

Additionally, too high of vitamin B6 intake can be dangerous and cause toxicity.

Symptoms of B6 toxicity can include nausea, headache, drowsiness, numbness or tingling, sensitivity to light, and gastrointestinal problems such as nausea and heartburn.

If you feel like you are experiencing any of these symptoms, we recommend consulting with your medical practitioner.

The Health And Brain Benefits Of Vitamin B6

Vitamin B6 is important for heart health, the digestive tract, muscular function, energy, and a whole lot of other bodily processes, too.

Our bodies use B vitamins to convert the food we eat into the energy we need to function. Together the complex of eight B vitamins are important for metabolism, brain and liver function, growth, and building blood cells, as well as for maintaining healthy hair, skin, and vision.

More specifically, vitamin B6 one of the eight plays key roles in keeping the brain and nervous system functioning properly, says Sonya Angelone, RDN, a spokesperson for the Academy of Nutrition and Dietetics. Vitamin B6 is involved in production of hemoglobin, the protein in blood that carries oxygen throughout the body.

Vitamin B6 is also needed for proper brain development and function . It helps the body make the hormones serotonin and norepinephrine . Vitamin B6 also helps the body make melatonin, which is important in helping regulate your internal clock and your sleep.

Toxicity Of Vitamin B6

Vitamin B6 is toxic at doses that are 1000 times the RDA. Daily doses of 2 to 5 grams of pyridoxine can produce difficulty in walking, and tingling sensations in the legs and soles of the feet. Continued consumption of the toxic doses results in further unsteadiness of walking, difficulty in handling small objects, and numbness and clumsiness of the hands. Where vitamin B6 supplementation is stopped, recovery begins after 2 months. Complete recovery may occur after 2 to 3 years of discontinuing consumption of the vitamin B6 supplements .

May Improve Mood And Reduce Symptoms Of Depression

Vitamin B6 plays an important role in mood regulation.

This is partly because this vitamin is necessary for creating neurotransmitters that regulate emotions, including serotonin, dopamine and gamma-aminobutyric acid .

Vitamin B6 may also play a role in decreasing high blood levels of the amino acid homocysteine, which have been linked to depression and other psychiatric issues .

Several studies have shown that depressive symptoms are associated with low blood levels and intakes of vitamin B6, especially in older adults who are at high risk for B vitamin deficiency .

One study in 250 older adults found that deficient blood levels of vitamin B6 doubled the likelihood of depression (

12 ).

A controlled two-year study in approximately 300 older men who did not have depression at the start found that those taking a supplement with B6, folate and B12 were not less likely to have depressive symptoms compared to the placebo group .

Summary Low levels of vitamin B6 in older adults have been linked to depression, but research has not shown that B6 is an effective treatment for mood disorders.

Medical Definition Of Vitamin B6

Vitamin B6

Reviewed on 3/29/2021

Vitamin B6: A group of closely related chemical compounds with related names — pyridoxine, pyridoxal and pyridoxamine — that are transformed within the body to yet another form of vitamin B6, pyridoxal phosphate, that acts as a coenzyme.

The vitamin B6 group is especially important to the function of the central nervous system, skin, and blood. Vitamin B6 is involved in the formation of red blood cells since pyridoxal phosphate is the rate-limiting substance in making heme, a component of hemoglobin, the key oxygen-carrying pigment in red blood cells.

The diet rarely lacks vitamin B6. Most foods contain it. However, deficiency of vitamin B6 within the body may occur due to poor absorption of it from the intestine or inactivation of it by some drugs . Other causes of vitamin B6 include alcoholism and conditions such as hyperthyroidism and diabetes that increase the metabolic demand, creating a relative shortage of vitamin B6.

Vitamin B6 deficiency causes convulsions in infants and anemia in adults. An outbreak of convulsions in infants followed the inadvertent destruction of vitamin B6 in infant formulas. Several genetic syndromes also involve problems with vitamin B6.

B6 May Help To Reduce The Risk Of Heart Disease

Science indicates that vitamin B6 functions may include reducing the risk of heart disease and preventing artery clogging.

Those who are deficient in B6 have been shown to be at almost twice as much risk of developing heart disease in comparison to those with high readings .

Researchers believe this occurs because B6 helps to lower homocysteine levels. This amino acid is commonly found within the body, however elevated amounts are associated with a number of diseases, including heart disease .

In this randomized trial, scientists used 158 participants whose siblings had heart disease. They split the group into two and supplemented half with a daily serving 125mg of vitamin B6 and 5mg of folic acid. This trial continued for 2 years and, by the end the participants who took the vitamin had lower homocysteine levels and were at lower risk of heart disease .

Key Point: Science shows hat supplementing with B6 may help to lower the risk of heart disease over time

Uses In Traditional Medicine

Many vitamin B6-rich foods have long been used in traditional medicine for their powerful effects on health and wellness. While these foods contain a wealth of other micronutrients and health-promoting properties that makes them especially beneficial for use in holistic medicine, their vitamin B6 content undoubtedly contributes to many of their favorable effects on health.

Grass-fed beef, for example, is one of the most concentrated sources of vitamin B6 and is believed to strengthen the blood and enhance red blood cell production according to Ayurveda. Its also thought to relax the mind, satisfy the stomach and improve liver function.

Similarly, pistachios are another vitamin B6-rich food that are used in Traditional Chinese Medicine to promote spleen health. They also help support the liver, heart and gallbladder and are thought to treat conditions like jaundice, which is caused by excess levels of a yellow pigment called bilirubin.
