1. What is vitamin B5?

Vitamin B5 (pantothenic acid) is a water-soluble B vitamin best known for its role in the production of adrenal hormones during times of stress. The name comes from the Greek pantothen, meaning "from everywhere" — reflecting that it is found in nearly all foods. Despite its widespread availability, modern lifestyles can deplete it through chronic stress.

Reference ranges and recommended intakes vary from country to country — always interpret guidance against the recommendations of your own healthcare authority.

2. Function and how it works

Vitamin B5 supports fertility in several ways:

1. Coenzyme A synthesis. Pantothenic acid is a precursor of coenzyme A, which is required for the metabolism of carbohydrates, fats and proteins.
2. Adrenal hormone production. Vitamin B5 is concentrated in the adrenal glands and is essential for the production of cortisol, DHEA and other steroid hormones.
3. Stress resilience. By supporting adrenal function, B5 helps the body cope with chronic stress, which is one of the most common modern factors disrupting fertility.
4. Energy production. As part of coenzyme A, B5 is integral to the citric acid cycle that generates ATP.

3. Fertility benefits

For couples experiencing fertility difficulties under chronic stress, vitamin B5 is a key supportive nutrient. By supporting healthy cortisol and DHEA production, B5 helps protect against the "pregnenolone steal" — the diversion of progesterone precursors to cortisol production under chronic stress — which can otherwise contribute to luteal phase defect.

4. Recommended daily dose

I recommend a daily dose of 6 mg of vitamin B5, typically obtained as part of a good-quality prenatal or B-complex supplement. Higher doses (up to 500 mg) are sometimes used in adrenal-support formulas under professional supervision.

5. Food sources

Vitamin B5 is found in nearly all unprocessed foods, including:

1. Whole grains
2. Beans, peas and lentils
3. Eggs
4. Nuts and seeds
5. Green leafy vegetables
6. Meats and offal
7. Royal jelly (a particularly concentrated source)

6. Cautions and contraindications

1. Pantothenic acid is very safe; toxicity from oral supplementation is extremely rare.
2. Very high doses can occasionally cause loose bowels.
3. Always consult with a fertility specialist or your doctor before starting any new supplement regime.
