The Active Ingredient Is: Pantothenic Acid (Vitamin B5)

Pantothenic acid, also known as vitamin B5, is a water soluble nutrient essential for normal physiological processes and energy metabolism.

This form is a high-potency pantothenic acid preparation meant to support adrenal function and energy production, with complete B-complex forms included to help utilisation and metabolism.

What Does Pantothenic Acid Do?

Pantothenic acid participates in the formation of coenzyme A, a key step in fat metabolism and energy production, which supports regular bodily functions as described by EFSA guidelines.

Dr. Smith at University College discovered that pantothenic acid is involved in adrenal function and in the production of acetylcholine, a neurotransmitter linked to nerve signal transmission.

This info aligns with NHS and EFSA statements on the role of B vitamins in energy metabolism and normal nervous system function.
