It is an attractive potential food source because it is high in protein and other essential nutrients; when dried, it is about 45% protein, 20% fat, 20% carbohydrate, 5% fibre, and 10% minerals and vitamins. Mass-production methods are now being used to cultivate it in large artificial circular ponds. Chlorella is a complete protein source.[dubious – discuss] It is also packed with calories, fat, and vitamins.
When first harvested, Chlorella was suggested as a "dirt-cheap" protein supplement to the human diet. Advocates sometimes focus on other supposed health benefits of the algae, such as claims of weight control, cancer prevention, and immune system support.
Under certain growing conditions, Chlorella yields oils high in polyunsaturated fats—Chlorella minutissima has yielded EPA at 39.9% of total lipids.
Several studies suggest Chlorella supplementation has a positive effect on the reduction of dioxin levels in breast milk and it may also have beneficial effects on nursing infants by increasing the IgA levels in breast milk.
Claims of health and healing effects
Like blue-green algae, clinical studies on Chlorella suggest effects including polychlorinated dibenzodioxins detoxification in humans and other animals, healing from radiation exposure in animals and the ability to reduce high blood pressure, lower serum cholesterol levels, accelerate wound healing, and enhance immune functions in humans.
Chlorella has been found to have anti-tumor properties when fed to mice. Another study found enhanced vascular function in hypertensive rats given oral doses of chlorella. However, the use of Chlorella for healing effects has received criticism.

(I cross-read though, if it's not a good read please let me know)
Else it seems to have received some positive feedback from cancer societies and the like.. well from what I can see coming out the Google results.
Finally, you can buy pure Chlorella on Ebay for approx. 80$ CAD per KG plus shipping (price may vary depending on your location - 80$ CAD is approx. worth $75 USD +/- $10 USD depending on the economy).Note: We get Vitamin C from fruits like oranges. We get Vitamin D3 by the UV from sunlight.
