Uses In Traditional Medicine

Vitamin B Complex Side Effects

Traditional systems of medicine, including Ayurveda and Traditional Chinese Medicine , recognized that the aging process causes changes in nutrient absorption and therefore a need to adjust someones diet to slow aging. In Ayurveda, the focus is commonly on boosting digestive fire , which helps the ability to break down and absorb the foods and liquids we consume. Warming spices, such as ginger, cinnamon and turmeric, are encouraged to promote a healthy appetite and metabolism.

A similar concept exists in Chinese medicine, in which attention is paid to the spleens energy , which helps facilitate digestion, especially after the age of 50 or 60. In Chinese medicine, dried orange peel, cumin, pepper, salt and sugar are said to support absorption of nutrients, including B vitamins. Drinking small amounts of green or black tea between meals may also be recommended to improve absorption and energy.

Because animal-derived foods are major sources of several of the B vitamins, a varied diet that includes both plants and animal products is encouraged in many traditional systems of medicine. According to Ayurveda, when someone enters the later stages of life dominated by the dosha called Vatta, that person may be encouraged to get B vitamins from plant foods, such as greens and legumes, as opposed to more calorie-dense foods.

Reap The Health Benefits Of B Vitamins

Good nutrition is tied to good health, as well as to the prevention and treatment of many conditions. Getting the recommended amounts of vitamins each day is an important part of the nutrition equation, and B vitamins are essential for preventive care. Abundant in green vegetables, whole or enriched grains, dairy, and meats, B vitamins help promote a healthy metabolism and are also linked to a reduced risk of stroke, research shows.

Take vitamin B12, for example. According to the Mayo Clinic, vitamin B12, a water-soluble vitamin, plays a significant role in nerve function, the formation of red blood cells, and the production of DNA. While most people get plenty of vitamin B12 benefits in a varied, balanced diet, if you are on a vegan or vegetarian diet, you are at risk for vitamin B12 deficiency. Also, elderly adults and people with GI disorders lack adequate B12.

  • Weakened immune system

Findings show that many people with depression have lower levels of folate in the blood. Folate is found in green leafy vegetables, beans, peas, peanuts, and other legumes, and citrus fruits. The Food and Drug Administration began requiring manufacturers to add folic acid to enriched breads, cereals, flours, cornmeal, pasta, rice, and other grain products in 1998.

Side Effects And Risks Of Vitamin B

B vitamins are water-soluble. This means that, most of the time, the body excretes extra B vitamins in the urine.

While a standard dosage does not seem to cause harm, excessively high doses of certain B vitamins can be dangerous. Speak with a clinician before taking very high doses of B-complex supplements.

Possible side effects of B-complex vitamins:

  • High blood sugar. High doses of nicotinic acid, a synthetic form of vitamin B3, can raise blood sugar levels. This can interfere with diabetes medications. People with diabetes or high blood sugar should not take high doses of nicotinic acid .
  • Excess nicotinic acid. Too much nicotinic acid can also cause low blood pressure, fatigue, headaches, rashes, and liver damage.
  • Excess nicotinamide. High doses of nicotinamide, another form of vitamin B3, can cause diarrhea and increased bleeding. This can occur in doses of 500 mg per day. Doses higher than 3,000 mg can cause vomiting and liver damage.
  • Excess folic acid. Taking more than 1,000 mcg of folic acid a day can mask a type of anemia caused by vitamin B12 deficiency.

Taking a high-dose B-complex supplement can also turn the urine bright yellow. This effect is temporary and harmless. Once the kidneys get rid of the extra vitamins, the color will return to normal.

Are Supplements Necessary

Most people get enough B vitamins through their diet. Whole foods are also the best way for your body to absorb these vitamins.

Its not necessary to take a supplement unless your doctor has confirmed that youre deficient in a specific B vitamin. If they note a deficiency, theyll most likely tell you whether you should take a specific B supplement or add a vitamin B complex supplement to your routine.

You may be more likely to need supplementation if you:

  • are age 50 or older
  • have certain chronic health conditions
  • take certain long-term medications
  • eat a strictly meat-free diet

One thing to keep in mind: Supplements arent regulated by the Food and Drug Administration , so you should only buy from a trusted, reputable brand. This helps ensure youre taking a high quality product without any questionable additives.

If your doctor has noted a deficiency, they may be able to recommend a specific brand of supplements.

You should always read all labels carefully and follow any directions given by the manufacturer. If you have questions about the dosage, talk with your doctor.

Produces Red Blood Cells

Vitamin B Complex Side Effects

Some B vitamins, particularly vitamin B12, play an essential role in the formation of red blood cells. Healthy red blood cells are needed to transport oxygen to every part of the body, and when there’s a vitamin B12 deficiency, the body will struggle to produce enough red blood cells, often leading to anemia.

Vitamins B2 and B9 are also needed for red blood cell production and growth. While vitamin B5 plays a role in red blood cell production, it also helps reduce the amount of cholesterol produced by the body. And vitamin B6, which is required for more than 100 different enzyme reactions in the body, aids in the formation of hemoglobin, which also allows red blood cells to carry oxygen through the blood.
