Did You Know Animals Form Vitamin C Own Their Own?

Animals can produce their own vitamin C e-g. rabbit produce 18,000mg (18g). of vitamin C every day.  Whereas human body cannot produce vitamin C. Additionally, vitamin C is water soluble vitamin that will lose from our body unceasingly. Therefore, it is necessary to take vitamin C every day. Vitamin C has no toxicity effect.

The studies by Dr James Scala have shown that it is safe to consume 5,000mg—(10 tablets) to 10,000mg (20 tablets) Vitamin C every day. Dr Pauling who discovered vitamin C took 18g (18,000mg) of vitamin C every day and he was fit and healthy even at the age of 94.

Is Vitamin C From Fruit Sufficient?

Each serving of fruit provides approximately 45-60mg of vitamin C. Fruit makes the complete vitamin C during its final 10 days to ripening, therefore, unripe fruit contain only very little vitamin C. The vitamin C in fruit will reduce to half once plucked and destroy when exposed to heat. To improve health and anti-cancer, nutritionists recommend the intake of more than 2000mg of vitamin C everyday (equivalent to 40 apples).

 Do You Eat The Skin of Fruit?

Fruit skin contains flavonoid which is also known as vitamin P. The main ingredients are rutin, hesperidin. They strengthen the blood capillary, prevent bruise and internal bleeding or stroke, as well as regulating blood pressure. As they aid blood circulation, hence the blood flow to males’ reproductive organ, they are likened as the natural Viagra.
