Vitamin B5 (Pantothenic Acid)

Vitamin B5 (Pantothenic Acid) is a water-soluble vitamin essential for the synthesis of coenzyme A (CoA), a critical molecule involved in fatty acid metabolism, energy production from carbohydrates and fats, and the synthesis of cholesterol, steroid hormones, and neurotransmitters. Pantothenic acid is widely available in foods, and deficiency is rare but can cause fatigue, irritability, and numbness. Blood levels reflect recent intake and overall nutritional status.
