The reasons why DNA collapsed is they got great distribution agreements and then did not advertise the product so it did not move well enough.
They likely did not advertise the product because they did not have the required funds is because of two reasons.
First, a major funding deal with a financial institution fell apart at the last minute, thus DNA did not get the anticipated funds that could have been used for advertising.
Second, before the Coca-Cola fiasco, Eric Fowler spent almost all of DNA's cash to purchase perishable inventory that DNA would not be able to sell before the inventory started to go bad. This inventory was later liquidated at a loss with Big Lots.
