Vitamin C, ascorbic acid, is a water soluble compound and is easily absorbed. However, it is not stored in the body. That is why it is important to daily consume foods or use supplements rich in Vitamin C.
What foods are rich in vitamin C? Fruits and vegetables are the best sources
oranges(90mg/cup),sweet peppers(230 mg/raw cup),tomato juice, (170 mg/cup),broccoli(74 mg/cooked cup),brussels sprouts(71 mg/cooked cup),kale(69mg/cooked cup),cauliflower(56 mg/cooked cup) to name a few!
Want to boost your immune system naturally, Vitamin C, ascorbic acid, is key. Vitamin C stimulates your immune system, specifically white blood cells (WBCs). Vitamin C also aides in the absorption of iron which is also very important to carry oxygen and fight off infection. I’m only focusing on Vitamin C in the context of infections. Needless, to say, Vitamin C has many other health benefits.
How much should I take? If you are deficient, you need more!
Viral infections, stress, smoking, fever, cause a rapid decline in blood levels of Vitamin C, or ascorbic acid. That is why it is important to use more and use it daily!
Dr. Stuart Nunnally, renown authority, recommends3000-10000 mg/day or 3-10 g/day.
The International Journal of Vitamin Nutritional Research found200 mg of vitamin Cper day resulted in an80% decrease in deaths among severely ill,hospitalized patients with pneumonia. That is a relatively small amount, which suggests deficiencies needs to be prevented.
With regards tocardiovascular disease and infection,100 mg/day of ascorbic acidis found to be sufficient to decrease LDL damage, and saturate WBCs in healthy individuals.
Can I take too much?
Doses over 500 mg/d may cause diarrhea or gastric distress. A study reported Vitamin C may increase the risk of cataracts were made at longterm at dose of 500mg/d.
In summary, little scientific evidence shows large doses of vitamin C are toxic or exert serious adverse health effects. It’s okay to take up to 10,000 mg/day or 10 grams/day.
The Mayo Clinic reportsheremedications that might be affected by Vitamin C, so check the list if you are on medications.
