Introduction
Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that plays a crucial role in cellular processes and overall health. It is involved in the synthesis of coenzyme A (CoA) and is essential for the metabolism of carbohydrates, proteins, and fats.
Key Insights from Research Papers
- Pantothenic acid is vital for cell building, supports normal growth and development of the central nervous system, and is involved in the production of adrenal hormones, which help the body respond to stress. A deficiency in Vitamin B5 can lead to symptoms such as chronic fatigue, hypoglycemia, graying and loss of hair, mental depression, stomach disorders, and blood and skin disorders.
- The vitamin is found in a variety of foods, including whole grains, green vegetables, peas, beans, peanuts, and egg yolk. While the minimum daily requirement has not been firmly established, it is estimated to be between 30 and 50 mg per day, with therapeutic doses ranging from 50 to 200 mg. High doses of 1,000 mg or more daily have been administered for six months without reported side effects, indicating a high level of safety.
- Nutritional deficiency of pantothenic acid is rare due to its wide distribution in both animal and plant-source foods, and toxicity from the vitamin is considered negligible. Current literature does not associate pantothenic acid with any health concerns, and due to limited data, no dietary reference values have been established in the Nordic Nutrition Recommendations since 2012.
Conclusion
Vitamin B5 is essential for numerous bodily functions and is generally safe for consumption. It is widely available in various foods, and deficiencies are uncommon. High doses have been used therapeutically without reported side effects, suggesting a low risk of toxicity. Current research does not link pantothenic acid with any adverse health issues.
