500 mg per cap doesn't necessarily means that inside those 500 mg yuo have
effective 500 mg of B5, because in the pill there are other things, so maybe
somwhere inthe bottle you find a B5 300 and I think that is the net part of
B5.
Anyway calculate the total net grams of the bottle, divide per number of
pills and you get the weight of one pill, if you get 500 mg for eache one
it's kinda hard that 500 mg are pure B5,
so you could search on the label or ask the producer how much B5 you have
per pill.
