Ever feel like your energy is running low, or that stress is taking a toll? You might have heard of the B vitamins, but there's one that quietly works behind the scenes to help you produce energy and manage stress: pantothenic acid, also known as vitamin B5.
Pantothenic acid is a water-soluble B vitamin that is essential for making coenzyme A — a molecule that helps your body break down fats, carbohydrates, and proteins for energy. It also plays a key role in the production of stress-related hormones. The name "pantothenic" comes from the Greek word "pantothen," meaning "from everywhere" — a nod to its widespread presence in foods.
Pantothenic acid (vitamin B5) is one of the eight B vitamins. Its primary role is to help form coenzyme A, which is involved in more than 70 different enzymatic reactions in your body. These reactions include the breakdown of fatty acids, the synthesis of cholesterol and hormones, and the production of energy from food.
Because it's so widespread in foods, deficiency is rare. But its role in energy metabolism and hormone production makes it an important nutrient for overall vitality.
Pantothenic acid helps convert carbohydrates, fats, and proteins into usable energy. It's a critical component of coenzyme A, which is involved in the Krebs cycle — the process that generates energy in your cells. Without enough B5, your body would struggle to produce the fuel it needs.
Your adrenal glands rely on pantothenic acid to produce stress hormones like cortisol. When you're under pressure, your body uses more of these hormones, which may increase your need for B5. Adequate levels can help your system respond more effectively to daily stressors.
Pantothenic acid is involved in the production of skin lipids and helps maintain the skin barrier. It's sometimes used in skincare formulations for its moisturising and soothing properties. Some research has explored its role in supporting skin health.
Like other B vitamins, pantothenic acid contributes to the formation of red blood cells. Healthy red blood cells are essential for carrying oxygen throughout your body, which affects everything from energy to cognitive function.
Through its role in fat metabolism, pantothenic acid helps your body process fats, which can influence cholesterol levels. While dietary B5 is part of a balanced approach to heart health, its exact effects are still being studied.
Pantothenic acid is water-soluble, meaning your body absorbs it quickly and excretes excess in urine. It's widely available in foods, so most people get enough through a varied diet. Absorption occurs in the small intestine, and the body has a limited storage capacity, so regular intake is beneficial.
Because it's so common in foods — from meat and eggs to vegetables and whole grains — deficiency is extremely rare in healthy individuals.
Pantothenic acid from food is very safe. Even at high doses, supplements are generally well-tolerated, with few reported side effects. Very high doses may occasionally cause mild digestive upset, such as diarrhea.
Because B5 is water-soluble, excess is usually excreted, making toxicity rare. If you're considering a B5 supplement, it's always wise to consult a healthcare professional, especially if you have underlying health conditions or are taking medications.
Eating a variety of these foods ensures you get enough pantothenic acid without any special effort.
Pantothenic acid may not be the most famous B vitamin, but its role in energy production, stress management, and skin health makes it a quiet essential. The good news? It's so widespread in foods that a balanced diet — including poultry, fish, eggs, mushrooms, and avocados — usually provides all you need. So next time you enjoy a slice of avocado or a handful of sunflower seeds, give a little nod to vitamin B5. It's helping your body turn food into fuel and supporting you through the day.

有没有感觉能量不足，或者压力让你疲惫不堪？你可能听说过B族维生素，但有一种B族成员一直在幕后默默工作，帮你制造能量、应对压力——它就是泛酸，也叫维生素B5。
泛酸是一种水溶性B族维生素，是制造辅酶A的关键原料。辅酶A帮助身体分解脂肪、碳水化合物和蛋白质来产生能量。它还参与制造压力相关的激素。"泛酸"这个名字源自希腊语"pantothen"，意思是"无处不在"——这也反映了它在食物中广泛存在的特点。
泛酸是八种B族维生素之一。它的主要作用是帮助形成辅酶A，辅酶A参与体内70多种不同的酶反应。这些反应包括脂肪酸分解、胆固醇和激素的合成，以及从食物中产生能量。
因为它在食物中分布极广，缺乏症非常罕见。但它在能量代谢和激素制造中的作用，使它成为维持整体活力的重要营养素。
泛酸帮助身体把碳水化合物、脂肪和蛋白质转化成可用的能量。它是辅酶A的关键成分，而辅酶A参与三羧酸循环——这是细胞产生能量的核心过程。没有足够的B5，身体就很难获得所需的燃料。
肾上腺依赖泛酸来制造压力激素，比如皮质醇。当面对压力时，身体会消耗更多这些激素，可能增加对B5的需求。泛酸充足时，身体能更有效地应对日常压力。
泛酸参与皮肤脂质的制造，帮助维持皮肤屏障功能。它有时被用于护肤配方中，有保湿和舒缓作用。一些研究探讨了它在支持皮肤健康方面的作用。
像其他B族维生素一样，泛酸也参与红血球的形成。健康的红血球对向全身输送氧气至关重要，这影响着从能量到认知功能的方方面面。
通过其在脂肪代谢中的作用，泛酸帮助身体处理脂肪，这可能影响胆固醇水平。食物中的B5是平衡心脏健康的一部分，但其具体作用仍在研究中。
泛酸是水溶性的，身体吸收快，多余部分随尿液排出。它在食物中分布极广，所以饮食多样化通常就能满足需求。吸收主要在小肠进行，身体储存能力有限，规律摄取有益。
因为它在肉类、鸡蛋、蔬菜、全谷物等食物中都非常常见，健康人群中几乎不会出现缺乏。
从食物中摄取泛酸非常安全。即使高剂量补充剂也通常耐受良好，副作用很少。极高剂量偶尔可能引起轻微肠胃不适，如腹泻。
因为泛酸是水溶性，多余部分通常被排出，毒性罕见。如果你考虑B5补充剂，尤其是有健康状况或正在服药，最好咨询专业人士。
把这些食物轮着吃进日常饮食里，就能轻松满足泛酸需求。
泛酸可能不是最出名的B族维生素，但它在能量制造、压力管理和皮肤健康方面的作用，让它成为不可或缺的幕后功臣。好消息是，它在食物中分布极广——禽肉、鱼、蛋、蘑菇、牛油果轮着吃，通常就能满足需求。下次吃一片牛油果或一把葵花籽时，可以默默感谢一下维生素B5。它正在帮你把食物变成能量，陪你度过每一天。
