I was wondering about the maltodextrin too..

Here's the answer:

"It is much better than the spray dried light-colored Camu-Camu which is first flash frozen, then thawed, liquefied and then spray dried onto maltodextrine. Maltodextrine is just a cheap filler.

FALSE: Whole World Botanicals is proud of the fact that we don’t adulterate our products with excipients, flow agents, coloring, sugar—or any other additives. So when you find maltodextrin in our light Royal Camu product, you have to know that it’s there on purpose for a very good reason. Vitamin C is so highly unstable that once you, for example, cut open an orange, its Vitamin C begins to evaporate in the air. The sooner you eat it the better.

A starch, such as maltodextrin, have the unique and amazing property of stabilizing the Vitamin C in the Royal Camu Powder and Capsules. So even if you buy the product two years after its manufacture, it will contain most of its Vitamin C. Some people love our Dark Camu product because it has no additives at all, but it doesn’t have the same level of Vitamin C derived from the Camu-Camu fruit a few months after manufacture. Still, it does have some Vitamin C and all of the other synergistic phytochemicals which gave Camu-Camu fruit its special healing and balancing properties.

Camu-Camu, with its high natural Vitamin C complex is generally great for energy and for alleviating symptoms of cold/flu. It is also very popular for its mood balancing properties."
