Pantothenic acid (vitamin B5) is an essential water-soluble vitamin involved in energy metabolism, steroid hormone synthesis, and the production of coenzyme A, a critical molecule in numerous biochemical pathways. It is commonly included in B-complex supplements and multivitamins, and deficiency is rare in well-nourished populations. However, higher doses are sometimes used to support skin health, athletic performance, or stress response, though robust clinical evidence for these uses is limited [1].
This Nutricost product delivers 500mg of pantothenic acid per capsule—significantly higher than the recommended daily allowance (RDA) of 5mg—suggesting it is intended for therapeutic or high-dose supplementation rather than basic nutritional adequacy. It also contains 40mg of calcium, a modest amount compared to typical calcium supplements. The formulation appears targeted toward individuals seeking high-dose B5 support, possibly for acne, fatigue, or metabolic health, though clinical trial data on such uses are inconclusive [2].
Quick Summary
All ingredient amounts are clearly listed with no proprietary blends, allowing full transparency into the formulation.
The 500mg dose of pantothenic acid aligns with clinical studies for acne and energy support, though evidence is mixed. The calcium dose is too low to produce any measurable health benefit.
Pantothenic acid is typically well-absorbed in its standard form (e.g., calcium pantothenate), earning high bioavailability credit. Calcium at 40mg is absorbable but too low to be meaningful.
Both ingredients are safe at the provided doses, with no major interactions or adverse effects expected. High-dose B5 is well tolerated, and 40mg calcium poses negligible risk.
Why Take This Product
Key Benefits
- Supports Energy Metabolism: Pantothenic acid is a key component of coenzyme A, which is essential for breaking down carbohydrates, fats, and proteins into usable energy, helping reduce fatigue and support physical performance.
- May Improve Acne Symptoms: Some clinical studies suggest high-dose vitamin B5 can reduce sebum production and improve mild to moderate acne, though more research is needed to confirm efficacy [2].
- Supports Adrenal Function: As a cofactor in steroid hormone synthesis, B5 may help support adrenal gland function during periods of physical or emotional stress.
- Minimal Calcium Support: The 40mg of calcium contributes a small amount toward daily needs and may support bone and muscle health, though it is not a primary source.
Who Should Take This
Potential Side Effects
Ingredient Breakdown
Each capsule contains two ingredients: pantothenic acid (vitamin B5) at a high dose of 500mg and a small amount of calcium (40mg). Pantothenic acid is provided in its standard, well-absorbed form (calcium pantothenate or similar), commonly used in supplements. Calcium is included in a minimal quantity, likely as a stabilizer or excipient rather than for therapeutic effect.
Primary Ingredients
Vitamin B5
Coenzyme A synthesis, energy metabolism, hormone production
Adequate per single capsule
Vitamin B5 is essential for converting food into energy and producing cholesterol, steroid hormones, and neurotransmitters. High doses are sometimes used for acne and stress support.
Calcium
Bone health, muscle function, nerve signaling
Need 25-30 capsules daily for clinical levels — not feasible; insufficient for therapeutic use
Calcium is a vital mineral for maintaining strong bones and supporting muscle and nerve function. It may also play a role in blood pressure regulation.
Practical Recommendations
- Consider For Acne Or Fatigue Support: If you're exploring high-dose B5 for acne or low energy, this product provides a clinically relevant dose, though results may vary and can take several weeks to appear.
- Pair With A Balanced Diet: Ensure adequate intake of other B-vitamins and nutrients, as isolated high-dose B5 may not provide full metabolic benefits without cofactors.
- Not A Calcium Source: Do not rely on this product for calcium needs; use a dedicated calcium supplement if required, especially for postmenopausal women or older adults.
Is it Safe?
This product contains ingredients with strong safety profiles at the provided doses. Pantothenic acid has no established upper limit due to low toxicity, and calcium at 40mg poses negligible risk. No major drug interactions are known for B5, though high calcium intake can interfere with certain medications. Always consult a healthcare provider if you have kidney disease or are on medication.
Safety & Considerations
- Calcium Content: The calcium amount is minimal and not a concern for most, but individuals on strict calcium-restricted diets should be aware of cumulative intake.

The Science
The 500mg dose of pantothenic acid exceeds typical dietary intake (4–7mg/day) and aligns with higher doses used in clinical studies for acne and metabolic support. While some trials suggest benefit, overall evidence for measurable health outcomes remains limited [1][2]. The calcium dose is too low to impact bone or cardiovascular health meaningfully.
Discusses B-vitamin supplementation in older adults and notes limited evidence for improved health outcomes despite widespread use.
Reviews evidence for vitamin benefits, indicating that while some uses for B5 are proposed, proven benefits are limited.
Examines cardiovascular risks of calcium supplements, relevant for higher-dose formulations, though not applicable here due to low dose.
Evaluates calcium supplementation and lipid profile, showing inconclusive results, but again at much higher doses than provided.
