Vitamin C: Vitamin C daily can help prevent the flu.
Clinical studies have shown that large megadoses of Vitamin C are bit absorbed by the body.
Vitamin C is concentrated in the white blood cells that fight disease. Vitamin C is a free radical scavenger and helps protect the white blood cells.
Research has shown that vitamin C taken daily can prevent a cold or flu or shorten the duration. It is best taken daily as prevention.
A 1999 study published in the Journal of Manipulative and Physiological Therapeutics indicated that 1,000 mg of vitamin every hour for 6 hours and 1,000 mg three times daily afterward can effectively relieve or even prevent flu symptoms.
Warnings: If you take vitamin C with a calcium supplement, you will not get diarrhea. Reduce dosage if there is a history of kidney stones. Megadosing can also interfere with diabetes testing and blood clotting.
Dosage: 500 and 1,000 milligrams daily, up to 10,000 milligrams daily when fighting the flu. A possible alternative is to start with 3000 mg and then 1000 mg an hour until symptoms decrease.
