What does vitamin B5 actually do in the body?

Vitamin B5 (pantothenic acid) is the building block for Coenzyme A (CoA), a molecule your body needs to turn the carbohydrates, fats, and protein you eat into usable energy. CoA is also required to make cholesterol, steroid hormones, and acetylcholine, the neurotransmitter your nerves use to signal your muscles and organs.

Why is vitamin B5 called 'the vitamin nobody talks about'?

Because it's genuinely rare to be deficient in it. Pantothenic acid takes its name from the Greek word 'pantos,' meaning 'everywhere,' since it's present in nearly every food. True dietary deficiency is uncommon outside of severe malnutrition, chronic alcoholism, or significant digestive malabsorption — which is exactly why it rarely comes up, even though it's foundational to how your body produces energy every single day.

What are the symptoms of vitamin B5 deficiency?

Documented symptoms include fatigue, irritability, insomnia, burning or tingling sensations in the feet, muscle cramps, digestive disturbances such as nausea and abdominal pain, increased susceptibility to infections, and hair loss as a later sign. These symptoms are nonspecific individually, which is part of why B5 deficiency is easy to overlook.

Is vitamin B5 deficiency actually common?

No — true dietary deficiency is genuinely rare given how widespread pantothenic acid is in food. It's mostly seen in cases of severe malnutrition, chronic alcoholism, extreme caloric restriction, or significant gastrointestinal malabsorption. That said, milder, subclinical insufficiency may still play a role in fatigue and reduced stress resilience even without meeting full clinical deficiency criteria.

Can vitamin B5 deficiency cause hair loss?

Hair loss has been documented as a later sign of significant B5 deficiency, linked to impaired keratin synthesis, since CoA is involved in building the proteins hair is made of. It's typically one of the later symptoms to appear rather than an early warning sign on its own.

How is vitamin B5 connected to acetylcholine and nerve function?

Coenzyme A, which is synthesized from pantothenic acid, is required to produce acetylcholine, the neurotransmitter responsible for carrying signals from nerves to muscles and to organs including the heart and digestive system. This is part of why significant B5 deficiency can affect muscle coordination and nerve function.

What foods contain vitamin B5?

Pantothenic acid is found in a very wide range of foods, including meat and organ meats, legumes and beans, sweet potatoes, nuts and seeds, eggs, and dairy. Its presence in nearly all food groups is exactly why isolated deficiency from diet alone is uncommon.

Who is actually at risk of vitamin B5 deficiency?

People experiencing severe malnutrition or starvation, chronic alcoholism, extreme caloric restriction, or significant gastrointestinal conditions that impair nutrient absorption, such as chronic diarrhea or malabsorption disorders, are the groups where true deficiency has actually been documented.

How much vitamin B5 does an adult need daily?

ICMR-NIN's 2020 RDA for adults is 5mg per day. Because absorption efficiency decreases at very high supplemental doses, a maintenance-level daily dose is generally more practical than a large one-time amount.

What is calcium pantothenate, and how is it different from pantothenic acid?

Calcium D-Pantothenate is a stable, calcium-bound salt form of pantothenic acid commonly used in supplements because pure pantothenic acid is difficult to stabilize. Once absorbed, it functions the same way in the body as dietary pantothenic acid.

Does vitamin B5 help with stress?

Some clinical literature associates low B5 status with reduced resilience under stress and with symptoms like fatigue and irritability, given CoA's role in producing steroid hormones. This is a documented association rather than a claim that B5 supplementation treats stress on its own.

Why does EVO HOMINUS include vitamin B5 in its multivitamin?

Calcium D-Pantothenate is included at 100% of the ICMR-NIN 2020 RDA (5mg) as part of a complete active B-complex, supporting the same energy-metabolism and CoA-dependent pathways as the rest of the formula, since B5 is foundational to how the other B-vitamins' functions actually get used by the body.

Q: What is burning feet syndrome?

Burning feet syndrome is the classic, historically documented sign of significant vitamin B5 deficiency — a burning, tingling sensation in the soles of the feet, often worse at night. It was first described in Japanese prisoners of war and concentration camp deportees during World War II. It's caused by demyelination of peripheral nerve fibers, since CoA is required to synthesize the fatty acids that make up the protective myelin sheath around nerves.

You’ve probably never once worried about your vitamin B5 levels. That’s not an accident — it’s the whole story. B5 is in almost every food you eat, quietly working behind the scenes every time your body turns a meal into energy you can actually feel. It rarely runs short. But when it does, the signs are distinctive enough that they were first documented in a World War II prison camp — and it’s worth knowing what they look like.

What vitamin B5 actually does for you

Every time you eat, something has to convert that food into energy your cells can actually use. Vitamin B5 is a core part of making that happen. It’s the building block for a molecule called Coenzyme A, which your body uses to break down the carbohydrates, fats, and protein in your meal and turn them into usable energy — the difference between food sitting in your stomach and food actually fueling you.

That same molecule also does two other things worth knowing about. It’s needed to build cholesterol and steroid hormones, and it’s required to produce acetylcholine — the signal your nerves send to tell your muscles to move and your organs to function. So B5 isn’t just an “energy vitamin” in an abstract sense; it’s involved in the actual mechanics of how your nervous system talks to the rest of your body.

Why it’s called “the vitamin nobody talks about”

Pantothenic acid gets its name from the Greek word “pantos,” meaning “everywhere.” That’s not a coincidence — it’s genuinely present in almost every food group: meat, legumes, eggs, dairy, sweet potatoes, nuts and seeds. Because it’s so widely available in a normal diet, a true, isolated deficiency from food alone is genuinely rare. That’s exactly why B5 doesn’t show up in conversation the way B12 or vitamin D does — it’s not that it’s unimportant, it’s that most people simply never run low enough for it to become a visible problem.

“It’s not that B5 doesn’t matter. It’s that it’s built into almost everything you eat — so the only time it becomes a real story is when something else has gone seriously wrong first.”

Why this vitamin stays quiet

Burning feet syndrome — the one thing worth knowing

When B5 deficiency does happen, it has a genuinely distinctive, well-documented sign: burning feet syndrome — a burning, tingling sensation in the soles of the feet, often worse at night. This isn’t a modern internet symptom list invention. It was first clinically described in Japanese prisoners of war and concentration camp deportees during World War II, in populations experiencing severe, prolonged malnutrition.

What’s happening underneath it: without enough Coenzyme A, the body struggles to make the fatty acids needed to maintain the protective myelin sheath around peripheral nerves. When that protective layer breaks down, nerve signals misfire — which is what produces the burning, tingling sensation. It’s a serious sign, but also a genuinely rare one, appearing only in situations of significant, sustained deficiency.

Other symptoms worth knowing about

Fatigue and irritabilityCommonly reported, though nonspecific on their own — tied to B5’s role in energy production.

Trouble sleepingInsomnia and disrupted sleep are documented alongside other deficiency signs.

Muscle crampsReported alongside the nerve-related symptoms of more significant deficiency.

Digestive disturbancesNausea and abdominal discomfort are part of the documented symptom picture.

Getting sick more easilyCoA is required for antibody production, connecting B5 status to immune function.

Hair lossA later sign, linked to impaired keratin synthesis — not typically an early warning on its own.

Who’s actually at risk

Where real deficiency actually shows up

Documented risk groups

Severe malnutrition or starvation

Chronic, long-term alcoholism

Extreme, sustained caloric restriction

Significant gastrointestinal malabsorption, such as chronic diarrhea or malabsorption disorders

Not a meaningful risk factor on its own

Common misconceptions

A generally varied, adequate diet — B5’s presence across nearly all food groups makes isolated deficiency very unlikely here

Ordinary daily stress alone, without one of the risk factors above also present

Worth knowing: mild, subclinical shortfall might still contribute to fatigue in some people even without meeting full deficiency criteria

How EVO HOMINUS Addresses This

What to actually take away from this

Don’t panic about B5 deficiency — genuinely rare with a normal dietIts presence across nearly every food group makes isolated deficiency unlikely outside specific risk situations.

If you have burning or tingling feet, mention it to a doctorA distinctive, well-documented sign worth ruling in or out rather than ignoring, especially alongside other risk factors.

Chronic alcohol use or GI malabsorption changes the pictureThese are the situations where B5 status is genuinely worth paying closer attention to.

A complete B-complex covers B5 without you having to think about itSince it works alongside the other B-vitamins in energy metabolism, a formula that includes all of them at real doses is the simplest way to make sure it’s covered.

Common Questions

Vitamin B5, answered plainly.

Builds Coenzyme A, which turns food into usable energy, and is also needed to make cholesterol, steroid hormones, and the nerve-signaling molecule acetylcholine.

Its name comes from the Greek “pantos” — “everywhere” — because it’s in nearly every food. True deficiency is genuinely rare, which is exactly why it stays out of conversation.

The classic B5 deficiency sign — burning, tingling feet, worse at night. First described in Japanese POWs and camp deportees in WWII, caused by nerve myelin breakdown from CoA deficiency.

Fatigue, irritability, insomnia, burning/tingling feet, muscle cramps, digestive upset, more frequent infections, and hair loss as a later sign.

No — genuinely rare, mostly limited to severe malnutrition, chronic alcoholism, or major malabsorption. Mild subclinical shortfall may still contribute to fatigue in some people.

Documented as a later sign, linked to impaired keratin synthesis — not usually an early standalone warning.

CoA (from B5) is required to produce acetylcholine, the neurotransmitter carrying nerve signals to muscles and organs.

Meat, legumes, eggs, dairy, sweet potatoes, nuts and seeds — present across nearly every food group, which is why isolated deficiency is uncommon.

Severe malnutrition, chronic alcoholism, extreme caloric restriction, and significant GI malabsorption — the documented risk groups.

ICMR-NIN’s 2020 RDA for adults is 5mg per day.

A stable, calcium-bound salt form used in supplements since pure pantothenic acid is difficult to stabilize. Functions the same once absorbed.

Some clinical literature links low B5 status to reduced stress resilience, tied to CoA’s role in steroid hormone production — a documented association, not a standalone treatment claim.

Calcium D-Pantothenate at 100% RDA — foundational to how the rest of the active B-complex’s energy pathways actually function.
