Pantothenic Acid (Vitamin B5)
Required to synthesize coenzyme A (CoA), driving fatty acid metabolism, hormone production, and adrenal stress response.
What the evidence says
Pantothenic Acid appears to help in 6 of 7 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 2005–2024 with a typical study size of 32 participants.

Confidence
HighWhat the studies found
By outcome
Pantothenic Acid has an evidence score of 7.5/10 — strong evidence based on 24 indexed studies, including 4 meta-analyses. Required to synthesize coenzyme A (CoA), driving fatty acid metabolism, hormone production, and adrenal stress response.
The commonly studied dose of Pantothenic Acid is 100-500mg daily for B5; 600-900mg for pantethine. Research points to an estimated optimal dose around 500mg, with a minimum effective dose near 100mg. Individual response varies — start low and adjust.
The best time to take Pantothenic Acid is in the morning. Taking it with food is preferred. Pantothenic acid (vitamin B5) is a precursor to coenzyme A (CoA), central to energy metabolism, fatty acid synthesis, and acetylcholine production.

Pantothenic Acid (Vitamin B5) is essential for synthesizing coenzyme A (CoA), one of the most important molecules in metabolism. CoA is required for fatty acid synthesis, energy production, and the synthesis of acetylcholine, steroid hormones, and melatonin. While deficiency is rare, supplementation may support adrenal function during stress and is often included in B-complex formulas. Pantethine, a derivative, has specific benefits for lipid metabolism.

Loading: Not required
Take with food
| Form | Type |
|---|---|
| 💊Calcium D-Pantothenate or Pantethine | Recommended |
| 💊D-Pantothenic Acid | Alternative |
| 🧴Dexpanthenol (topical) | Alternative |
Calcium D-Pantothenate is standard. Pantethine is preferred for cholesterol-lowering effects but is more expensive.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Well-absorbed from food. Pantethine (for lipid effects) is typically taken in divided doses.
Based on systematic reviews showing B5 as generally safe and important for basic physiological functions. Limited direct outcome data for pantothenic acid specifically. Evidence primarily from general B-vitamin research and safety profiles.
Supports cellular energy production
May support adrenal function during stress
Pantethine form may improve cholesterol
Safe at recommended doses (6mg AI); essential for fetal development
Safe; adequate intake established by age group
Safe; no dose adjustment needed
Tip: Only at very high doses (10g+); reduce dose
Pantothenic Acid is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are diarrhea. Use caution if any of these apply to you: Known allergy or hypersensitivity to Pantothenic Acid or related compounds.
