You've probably heard of B12, biotin, and folate. But what about vitamin B5? Pantothenic acid is one of the most underrated B vitamins — yet your cells can't function without it. Let's give this unsung hero the attention it deserves, Singapore-style.
Pantothenic acid is vitamin B5, one of the eight essential B vitamins. Its name comes from the Greek word "pantothen," meaning "from everywhere" — because it's found in almost all foods. Your body uses it to create coenzyme A (CoA), a molecule that's involved in over 100 different chemical reactions. Without pantothenic acid, your body couldn't break down fats, produce energy, or make important hormones. Think of it as the factory worker that keeps production lines moving.
Pantothenic acid is a key component of coenzyme A, which helps convert carbohydrates, fats, and proteins into usable energy. Without enough B5, your body struggles to extract fuel from the food you eat. This is why it's fundamental to your daily energy levels.
Your adrenal glands need pantothenic acid to produce stress hormones like cortisol. When you're under pressure — whether from work, family, or daily life — your body uses more B5. Adequate intake helps your body respond to stress in a balanced way.
Pantothenic acid plays a role in breaking down fats, including cholesterol. Research suggests it may help support healthy cholesterol levels already within normal range when combined with a balanced diet.
Vitamin B5 is widely used in skincare products for its moisturising and soothing properties. It helps your skin retain moisture and supports the natural healing process. Some people also take it orally for skin health support.
Pantothenic acid is involved in the production of heme — a component of haemoglobin in red blood cells. Healthy red blood cells are essential for carrying oxygen throughout your body.
Pantothenic acid is highly bioavailable. Your body absorbs it efficiently from food in the small intestine. Unlike some other B vitamins, B5 is stable during cooking and food processing, so you retain most of it even in cooked meals. Because it's water-soluble, your body doesn't store large amounts — you need a regular intake from food.
Common side effects: Pantothenic acid is extremely safe. Because it's water-soluble, your body pees out excess amounts. Side effects are very rare. Some people taking very high doses (from supplements) may experience mild digestive upset or diarrhoea, but this is uncommon.
Who should be careful: Pantothenic acid is generally recognised as safe for most people. However, anyone with a known medical condition or those taking prescription medications should consult a healthcare professional before starting any new supplement regimen. Pregnant and breastfeeding women should speak with their doctor first.
Overconsumption risks: There is very little risk of toxicity from pantothenic acid because excess is excreted in urine. Even high supplemental doses are generally well-tolerated. However, as with any nutrient, more isn't necessarily better — food sources are always the best foundation.
Pantothenic acid is truly everywhere — in eggs, meat, vegetables, grains, and dairy. Most people get plenty of B5 from a balanced diet without even trying. Because it's so widespread, true deficiency is extremely rare. If you're eating a variety of whole foods, you're likely getting what you need. As always, food first. If you have specific health concerns, talk to a healthcare professional.
