Vitamin B6 is a water-soluble vitamin that is naturally present in many foods, added to others, and available as a dietary supplement. It is the generic name for six compounds (vitamers) with vitamin B6 activity: The human body absorbs vitamin B6 in the jejunum. Phosphorylated forms of the vitamin are dephosphorylated, and the pool of free vitamin B6 is absorbed by passive diffusion.
Vitamin B6 is found in a wide variety of foods. The richest sources of vitamin B6 include fish, beef liver and other organ meats, potatoes and other starchy vegetables, and fruit (other than citrus). In the United States, adults obtain most of their dietary vitamin B6 from fortified cereals, beef, poultry, starchy vegetables, and some noncitrus fruits. About 75% of vitamin B6 from a mixed diet is bioavailable.
Signs You’re Not Getting Enough Vitamin B6;
Whole Body Impact
This hard-working vitamin holds many big jobs. It affects your mood, appetite, sleep, and thinking. You need it to fight off infections, turn food into energy, and help your blood carry oxygen to all corners of your body. While it’s actually rare to run low, you really can’t afford to do so.
Flagging Energy
If your body is very low on B6 (which is rare), you can get anemia, which is too few red blood cells. That would make you feel tired and weak. Anemia can also come from not having enough iron in your body. Shortages of other vitamins, like B12 and folate, also may cause it.
Seniors may run low on B6 if they don’t eat enough food or because their bodies don’t absorb nutrients as well as before. Kidney disease and other conditions that keep your small intestine from taking in nutrients also can be culprits. So can alcohol abuse. Some prescription medicines can also cause you to not have enough B6. If your doctor prescribes a new medicine, don’t hesitate to ask about its overall effect on your body.
Rashes
Signs that you lack B6 can show up on your skin. Your body goes through chemical changes. That most often leads to a scaly, itchy rash, usually on your face, called seborrheic dermatitis. The rash may get more and more obvious with time. If you have a minor shortage, the symptoms could take months or years to show up.
Dry, Cracked Lips
Your mouth could be a good place to spot any shortage of B6. Your lips might be scaly, and the corners could be cracked. Your tongue might swell.
Weak Immune System
A shortage of B6 may make it harder for your body to resist infections and diseases. That can turn into a vicious cycle. Cancer and other illnesses can deplete your B6 supply. So you’d need to get even more of the vitamin to make up for that. You can do that easily with a B6 supplement.
Numb Hands or Feet
Do your fingers tingle? Do your feet feel numb? The culprit may be a nerve disorder called peripheral neuropathy. Lack of B6 may help trigger it. It and other B vitamins like B12 are essential to keep your nerves healthy.
Cranky Baby
A fussy baby could be trying to tell you they’re low on B6. That could happen if you feed your infant nothing else but breast milk for more than about 6 months. Too little of the vitamin can even lead to seizures. It also can make your baby’s hearing extra sensitive so that noises can easily upset them.
Morning Sickness
Moms-to-be need more B6 in their diet than anyone else. If you’re feeling sick with nausea or vomiting (and not just in the mornings), a B6 supplement may help. But you should take it only with your doctor’s guidance.
Foggy Brain
B6 helps regulate your mood and memory. If you notice feeling confused or sad, especially if you’re a senior, a shortage of this vitamin could be the reason. It may make you more likely to get depressed after a stroke, fractured hip, or other major illness. B6 sometimes works in tandem with other B vitamins. If you run low, it may slow your mental abilities.
Cancer
Low B6 may play a role in your chances of having cancer. Researchers don’t know exactly why. But studies have linked a lack of B6 to stomach and esophageal cancers. A lack of the vitamin also may make you more likely to get cancers driven by steroid hormones, such as breast and prostate cancers.
