1. Vitamin C is a water-soluble vitamin and is only retained in the body for a maximum of 4 hours before it is either oxidised or excreted in the urine, so Vitamin C overdose is uncommon. Because of this short life in the body it is best to take Vitamin C in small, divided doses throughout the day Hypergh 14x results (at 4 hourly intervals).
2. The RDA (recommended daily allowance) for Vitamin C is 45-60mg per day. This is the smallest amount needed to prevent a life threatening disease; in the case of Vitamin C this is Scurvy. This amount, however, is certainly not the optimal amount needed for good health, this is 300mg-500mg daily depending on diet and lifestyle.
3. Things that can increase the need for Vitamin C supplementation are poor diet, eating processed or stored foods, pollution, toxic substances especially nicotine (each cigarette smoked depletes the body of 25mg of Vitamin C), DDT, stress, antibiotics, sulfa drugs, cortisone, aspirin, The Contraceptive Pill. Under any of the above circumstances a more suitable dose would be 1000mg-2000mg daily.
4. If an acute infection or inflammatory condition is being experienced such as a cold, flu or hay fever, increase the dosage to 1000mg every hour for six doses then 1000mg every 4 hours until symptoms improve.
5. Vitamin C overdose is extremely rare. Vitamin C is very safe to take as if too much Vitamin C is taken any excess will be excreted in the urine or as acid diarrhoea. Bear in mind this will only happen with very large, frequent doses. If this does occur reduce the dosage to a level where diarrhoea is not experienced.
