the scientific name for vitamin b 5 is pantothenic acid & whilst our body can’t make it (which is part of the definition of being a vitamin) we obtain it from bacteria living in our digestive system which can produce it as long as our systems are running smoothly.pantothenic acid plays a part in the processes that release energy from food & contributes to normal mental performance. it also contributes to the normal synthesis of our natural steroid hormones & nerve chemicals called neurotransmitters.this is a high strength pantothenic acid supplement & so doesn’t need to be taken for much longer than a few months after which one of our multis or a b complex will provide adequate levels. due to its strength we have made the tablets slow release so that they gradually release the pantothenic acid over a period of 5-6 hours after swallowing. this more closely matches the way a nutrient is released from food during digestion.high strength supplementmany times stronger than the level found in multis
