Vitamin B5: Energy, Skin & Metabolism Support
Vitamin B5: Energy, Skin & Metabolism Support
You've had your kopi and kaya toast, but by 10am you're already dragging. Before you blame the late night, it's worth knowing that turning any meal — nasi lemak, prata, or otherwise — into energy your body can actually use depends on a quiet nutrient most people never think about: vitamin B5.
What Is Vitamin B5?
Vitamin B5 is also known by its chemical name, pantothenic acid. It's one of the eight B vitamins, and its name comes from the Greek word for "everywhere" — a fitting description, since it's found in almost every food in small amounts.
Inside your body, vitamin B5 is used to build a molecule called coenzyme A. Think of coenzyme A as a tool that nearly every cell needs to break down the carbohydrates, fats, and proteins from your meals and repackage them as usable energy. Without enough B5, that tool simply can't be made.
Because it's water-soluble, your body doesn't store much of it. Whatever you don't use gets flushed out through urine, which is exactly why a steady supply from food matters more than a single big dose.
Why Do People Take It?
Turning meals into everyday energy
This is B5's headline job. It helps your body break down and use the fats and carbohydrates in everything from a plate of char kway teow to a bowl of oats. Because coenzyme A sits at the centre of this process, a shortfall in B5 can slow down how efficiently your cells generate energy, even if the effect is subtle in most healthy people.
Supporting skin health and healing
Vitamin B5 and its derivatives are widely used in skincare and dermatology, particularly for helping wounds heal and for calming irritated skin. Research on a pantothenic acid-based supplement also found a meaningful reduction in facial acne lesions over 12 weeks compared with a placebo, alongside improvements in how participants rated their skin-related quality of life. It's not a guaranteed acne fix, but it's an area of genuine scientific interest.
Helping manage cholesterol and blood fats
A specific derivative of B5 called pantethine has been studied for its effect on cholesterol and triglycerides. Clinical trials in people with mildly elevated cholesterol found modest but statistically significant reductions in total and LDL ("bad") cholesterol after several months of use, on top of a heart-healthy diet. Regular pantothenic acid from food doesn't appear to have the same strength of effect — this benefit is specific to the pantethine form studied in trials, and always alongside proper diet and medical guidance.
Supporting hormone production and cell communication
Because coenzyme A is involved in making cholesterol, which is the building block for several hormones, vitamin B5 plays a supporting role in hormone synthesis. It's also needed to convert pyruvate — a byproduct of digesting carbohydrates — into forms your body can use elsewhere, linking it into several metabolic pathways beyond just energy production.
Bioavailability & Absorption
Pantothenic acid is absorbed in your small intestine through a specific transport system that works together with biotin, another B vitamin. At typical dietary intakes, this transporter does most of the work; at very high intakes, the transporter becomes saturated and a smaller proportion gets absorbed through simple diffusion instead — meaning your body doesn't scale up absorption endlessly just because more is available.
Because pantothenic acid is water-soluble and not stored in meaningful amounts, consistent intake through regular meals matters more than occasional large amounts. Cooking methods that involve a lot of water and heat — think prolonged boiling — can also reduce the amount that ends up on your plate, since it leaches into the cooking liquid.
Safety Basics
True vitamin B5 deficiency is very rare, because it's present in almost all foods. When it does happen, it's usually alongside deficiencies in other nutrients, often in cases of severe malnutrition, which makes symptoms specific to B5 hard to pin down on their own.
People with a rare inherited condition affecting how the body processes pantothenic acid are at higher risk of deficiency and should be guided by a specialist rather than self-supplementing. Pregnant and breastfeeding women have slightly higher needs and should check with their doctor before starting any new supplement.
Vitamin B5 from food is considered very safe, and there's no known meaningful interaction between pantothenic acid and common medications. Very high-dose supplements — well beyond what a typical multivitamin or diet provides — have occasionally been linked to stomach upset or loose stools, which is a good reason to stick to food-first habits and speak with a pharmacist or doctor before adding a standalone B5 supplement.
Natural Food Sources
The good news for anyone eating a typical Singaporean or Malaysian diet is that vitamin B5 turns up almost everywhere — chicken rice, egg dishes, and a bowl of mushroom-topped noodles are all quietly contributing. Good sources include:
- Chicken, beef, and organ meats
- Eggs (a common ingredient in kaya toast, economy rice, and char kway teow)
- Mushrooms, avocado, and broccoli
- Whole grains such as brown rice and oats
- Legumes, including lentils and soybeans (found in tofu and soy-based dishes)
- Fish, shellfish, and dairy products like milk and yogurt
- Sunflower seeds and peanuts
Because milling and heavy processing can strip out a good portion of a food's natural B5 content, choosing less-processed grains and freshly cooked dishes over highly refined, packaged alternatives helps you get more of it naturally.

Final Thoughts
Vitamin B5 rarely gets the spotlight the way vitamin C or vitamin D do, but it's working behind the scenes every time your body converts a meal into energy. For most people eating a varied Singaporean or Malaysian diet — with regular eggs, whole grains, chicken, and vegetables — getting enough B5 isn't usually a struggle. The bigger opportunity is simply noticing how this quiet vitamin supports everything from your energy levels to your skin, and choosing whole, minimally processed foods often enough to keep that supply steady.
