Pantothenic Acid and Pantethine Overview

The body uses pantothenic acid (better known as vitamin B 5 ) to make proteins as well as other important chemicals needed to metabolize fats and carbohydrates. Pantothenic acid is also used in the manufacture of hormones, red blood cells, and acetylcholine, an important neurotransmitter (signal carrier between nerve cells).

As a supplement, pantothenic acid has been proposed as a treatment for rheumatoid arthritis , enhancing sports performance , and fighting stress in general.

In the body, pantothenic acid is converted to a related chemical known as pantethine. For reasons that are not clear, pantethine supplements (but not pantothenic acid supplements) appear to reduce blood levels of triglycerides and possibly also improve the cholesterol profile.

The word pantotheniccomes from the Greek word meaning "everywhere," and pantothenic acid is indeed found in a wide range of foods. For this reason, pantothenic acid deficiency is rare. The official US and Canadian recommendations for daily intake of pantothenic acid are as follows:

• Infants

• 0-6 months: 1.7 mg

• 7-12 months: 1.8 mg

• Children

• 1-3 years: 2 mg

• 4-8 years: 3 mg

• 9-13 years: 4 mg

• Males and Females

• 14 years and older: 5 mg

• Pregnant Women: 6 mg

• Nursing Women: 7 mg

Brewer's yeast, torula (nutritional) yeast, and calf liver are excellent sources of pantothenic acid. Peanuts, mushrooms, soybeans, split peas, pecans, oatmeal, buckwheat, sunflower seeds, lentils, rye flour, cashews, and other whole grains and nuts are good sources as well, as are red chili peppers and avocados. Pantethine is not found in foods in appreciable amounts.

For lowering triglycerides , the typical recommended dosage of pantethine is 300 mg 3 times daily. Dosages of pantothenic acid as high as 660 mg 3 times daily are sometimes recommended for people with rheumatoid arthritis .

High Triglycerides/High Cholesterol

Three small double-blind, placebo-controlled studies suggest that pantethine can reduce total blood triglycerides and perhaps improve cholesterol levels as well. ^{1 2} For example, a double-blind placebo-controlled study followed 29 people with high cholesterol and triglycerides for 8 weeks. ³ The dosage used was 300 mg 3 times daily, for a total daily dose of 900 mg. In this study, subjects taking pantethine experienced a 30% reduction in blood triglycerides, a 13.5% reduction in LDL ("bad") cholesterol, and a 10% rise in HDL ("good") cholesterol. However, other small studies have found no benefit. ⁴ These contradictory results do not necessarily mean that pantethine is ineffective, as chance plays a considerable role in the outcome of small studies. Rather, they suggest that larger studies need to be performed to establish (or disprove) panthethine’s potential efficacy.

Several open studies have specifically studied the use of pantethine to improve cholesterol and triglyceride levels in people with diabetes and found it effective ^{5 6 7} without causing harmful effects

These findings are supported by experiments in rabbits, which show that pantethine may prevent the build-up of plaque in major arteries. ⁸ However, we don't know how pantethine acts in the body to reduce triglycerides.

Rheumatoid Arthritis

There is weak evidence for using pantothenic acid to treat rheumatoid arthritis . One observational study found 66 people with rheumatoid arthritis had less pantothenic acid in their blood than 29 healthy people. The more severe the arthritis, the lower the blood levels of pantothenic acid were. ⁹ However, this result doesn't prove that pantothenic acid supplements can effectively reduce any of the symptoms of rheumatoid arthritis.

To follow up on this finding, researchers then conducted a small placebo-controlled trial involving 18 subjects to see whether pantothenic acid would help. This study found that 2 g daily of pantothenic acid (in the form of calcium pantothenate) reduced morning stiffness, pain, and disability significantly better than placebo. ¹⁰ However, a study this small doesn't mean much on its own. More research is needed.
