These nutrients also stimulate your immune system to fight infection. Work up to 5,000 mg a day over a week to prevent digestive upset and loose stools. As your symptoms clear up, gradually lower your vitamin C intake back to 3,000 mg per day. Do not reduce your dosage suddenly, as this can trigger a rebound effect. Take 750 mg to 1,000 mg of magnesium per day.
Magnesium acts as an antihistamine to clear air passages.
A potent antioxidant multivitamin should contain 500 mg of magnesium, so add 250 to 500 mg per day. Take thymus extract. Your thymus gland releases proteins that are critical to immune system function. Thymus products vary greatly in quality. One of the best I've found is ProBoost dehydrated thymus protein, which is dissolved under the tongue.
