Vitamin C, on the other hand, whether gotten from fruits like orange, grape, fruit juice, or tablets sold in pharmacies, helps with the absoption of iron which goes mostly to the liver and blood. This may be good for a patient who has anaemia as it helps to build up blood in the body, but it is detrimental to people who have malaria as the malaria parasites will have more iron to feed on and growfurther.Also, Vitamin C helps young malaria parasites grow to maturity in the body.
