Acido Pantotenico
Also known as: Vitamin B5, Biochinamide, Calcium pantothenate, D-pantothenic acid, Pantothenate, Pantothenic acid
Overview
Pantothenic acid, also known as vitamin B5, is a water-soluble vitamin essential for various physiological functions. It is naturally present in many foods including meats, whole grains, vegetables, and legumes, serving primarily in the synthesis of coenzyme A (CoA), an essential cofactor in fatty acid metabolism and energy production. Despite its wide availability in food sources, substantial losses can occur during food processing. Research on pantothenic acid demonstrates a moderate maturity level, emphasizing its biochemical roles in metabolism supporting overall health, although specific health benefits from supplementation remain less delineated.
Benefits
Pantothenic acid is crucial for metabolic health, particularly in the synthesis and utilization of fatty acids. Evidence suggests that pantethine, a derivative, may lower triglycerides and LDL cholesterol levels but specific benefits from pantothenic acid supplementation remain uncertain. Studies indicate that while its essential role in metabolism is well-established, the effect sizes related to lipid profiles and specific health outcomes from pantothenic acid alone are not uniformly recognized across populations.
How it works
Pantothenic acid functions predominantly as a precursor for coenzyme A (CoA), pivotal in numerous metabolic pathways, including the synthesis of fatty acids and energy generation from macronutrients. The vitamin aids in the transformation of carbohydrates, fats, and proteins into usable energy, facilitating critical metabolic processes. Its absorption is generally good across different dietary forms, such as calcium pantothenate; however, quantifiable data on comparative bioavailability are limited.
Side effects
Pantothenic acid is typically regarded as safe with little risk of toxicity due to its water-soluble nature. Common side effects, if any, are infrequent, and significant adverse reactions are largely undocumented. It poses minimal risks for most populations; however, consultation with healthcare providers is advised for pregnant or nursing women. There are no known serious interactions with medications, making it an overall low-risk supplement.
Dosage
While the dietary intake of pantothenic acid varies, supplements typically contain doses between 10 mg to 1,000 mg per serving. The appropriate dosage for achieving specific health benefits remains undefined, and while higher doses are tolerated well, setting an upper limit is not established. It is advisable to take pantothenic acid with food to potentially enhance absorption, although specific studies on this timing are lacking.
