Vitamin B Complex

Vitamin B Complex

Uses

This product is a combination of B vitamins used to treat or prevent vitamin deficiency due to poor diet, certain illnesses, alcoholism, or during pregnancy. Vitamins are important building blocks of the body and help keep you in good health. B vitamins include thiamine, riboflavin, niacin/niacinamide, vitamin B6, vitamin B12, folic acid, and pantothenic acid.

Some brands of B vitamins also contain ingredients such as vitamin C, vitamin E, biotin, or zinc. Consult your doctor or pharmacist if you have questions about the ingredients in your brand.

How do B Vitamins Work?

The B vitamins work in many different ways. Some function at the most basic level of our biology by influencing the activity of our genes. Other B vitamins work at a nongenetic biochemical level, such as by helping to make neurotransmitters, which modulate our moods, or by regulating blood sugar levels or specific risk factors for heart disease.

Who Should Take a B-Complex Vitamin?

Since B vitamins are found in many foods, you are most likely not at risk of developing a deficiency as long as you follow a well-rounded diet.

However, certain circumstances increase the need for B vitamins, making supplements necessary.

Potential Side Effects

Since B vitamins are water-soluble, it’s unlikely that you will consume too much of these nutrients through diet alone or by taking a B-complex supplement as directed.

However, taking supplements that contain excessively high and unnecessary quantities of B-complex vitamins could lead to serious side effects.

High doses of supplemental B3 (niacin) may lead to vomiting, high blood sugar levels, skin flushing and even liver damage (34).

Additionally, high doses of B6 can cause nerve damage, light sensitivity and painful skin lesions (35).

Another side effect of B-complex supplements is that it can turn urine bright yellow.

Although discolored urine can be shocking, it’s not dangerous but simply your body getting rid of excess vitamins that it can’t use.

If you need to take a B-complex supplement, always choose reputable brands that volunteer to have their products independently tested by organizations like the US Pharmacopeial Convention (USP).
