yes i did the arithmetic - 500 mg means 30 pills to get 15 g...

hmmm... did i have a typo somewhere? hmmm i will check, since you are pointing out the conversion?
that's great they aren't fishy. i think mine were by "Mar-Vit" ? not sure if that is sold in the US. i wonder if you can find that brand in a health store near you somewhere. stores that deal in those products should have a transportation process in place that guarantees the integrity of the product. why do i say this...

i would be very cautious about buying any sort of supplement online or any way that involves shipping. i would especially
avoid having oil-based supplements shipped to me because during travel shipments may end up held in areas (units, compartments) with
very high temps. those oils are susceptible to
chemical changes that happen very quickly with heat exposure.
if oil becomes rancid, not only would its ingestion not be beneficial, but it would actually be harmful. since they are in capsules you would not know if they are rancid. and if they are "off" but not rancid yet, you would not know even if you opened them and tasted it.
