Camu camu berry (vitamin c)
This powder is typical found in Vitamin C supplement capsules (e.g. Pure Radiance C, also available). 1/8 teaspoon equals about 500 milligrams of the powder. This means you can get 200 (1/8 teaspoon) servings per 100 gram bag. Since this is a food you can take greater amounts and increase its therapeutic benefit. It is useful in conjunction with MSM powder. Vitamin C can be very beneficial in healing and eliminating scar tissue.
The camu-camu berry is a source of phosphorus, calcium, potassium, iron, the amino acids serine, valine and leucine. Small amounts of the vitamins thiamine, riboflavin and niacin are also present.
Many have used camu-camu to support the immune system, maintain excellent eyesight, create beautiful skin, help maintain optimal clarity of mind in times of stress and anxiety. It is a great source of anti-oxidants and is an anti-viral. In studies of botanicals camu camu ranked #1 related to 12 common ailments that included things like Colds and Migraine headaches.
The uses and the daily requirement amounts of vitamin C are matters of on-going debate. People consuming diets rich in ascorbate from natural foods, such as fruits and vegetables, are healthier and have lower mortality from a number of chronic illnesses. However, a recent meta-analysis of 68 reliable antioxidant supplementation experiments involving a total of 232,606 individuals concluded that consuming additional ascorbate from supplements may not be as beneficial as thought. 
“Vitamin C has received a great deal of attention, and with good reason. Higher blood levels of vitamin C may be the ideal nutrition marker for overall health. The more we study vitamin C, the better our understanding of how diverse it is in protecting our health, from cardiovascular, cancer, stroke, eye health [and] immunity to living longer.”
– Mark Moyad, M.D., M.P.H., University of Michigan
Vitamin C is definitely one of the most important nutrients in our diets. While the immune system benefits of the vitamin are more recently being discovered, general health benefits of it are well established:
Stress: Vitamin C has been proven to help emotionally and physically in individuals whose immune systems are weak because of stress.
Common cold: The vitamin has been observed to prevent the worsening of common colds, although it does not cure them.
Stroke: A recent study found that individuals with the highest concentrations of vitamin C in their blood were at a 42% lower risk to have a stroke than those with the lowest levels.
Skin Aging: Vitamin C reduces wrinkles and dryness of the skin, while promoting a better skin-aging appearance as well.
Other, more noteworthy benefits of Vitamin have been hinted at in recent studies as well. These benefits include the improvement of macular degeneration, the reduction of inflammation, and even the reduction of cancer and cardiovascular disease risk.
The immune system benefits that arise from vitamin C intake derive from its involvement in many bodily processes such as the formation of collagen, absorption of iron, immune system activity, wound healing, and the maintenance of cartilage, bones, and teeth. Furthermore, vitamin C is an active antioxidant that protects against free radicals. Like zeolite, for example, this removal of free radicals by the vitamin allows the immune system to function more properly, and accounts for its benefit and support of our overall wellbeing.
