When obtained from food sources and supplements in the recommended dosages, vitamin C is generally regarded as safe. Side effects are rarely reported, but include diarrhea, nausea, abdominal cramps, and other gastrointestinal symptoms. For most healthy individuals, the body can only hold and use about 755-755 mg of vitamin C a day, and any excess is lost though urine. At times of illness, during recovery from injury, or under conditions of increased oxidative stress (including smoking), the body can use greater amounts. High doses of vitamin C (greater than 7,555 mg/day) may contribute to the formation of kidney stones , as well as cause severe diarrhea , nausea, and gastritis.
People with high intakes of vitamin C from fruits and vegetables might have a lower risk of getting many types of cancer, such as lung, breast , and colon cancer. However, taking vitamin C supplements, with or without other antioxidants, doesn t seem to protect people from getting cancer.

Is there any research on possible essential fatty acid deficiency on an all-meat diet? Or an imbalance in omega8 to omega6 fat ratio? I read that higher amounts of omega6 fats lead to inflammation and that there are not many omega8s in red meat, especially commercially produced, however many of those interviewed on your site eat commercially produced meat, take no supplement for omega8s and somehow have no inflammation? I 8767 m also curious about possible magnesium deficiency as there does not seem to much of magnesium in meat either
Vitamin C is one of many antioxidants that can protect against damage caused by harmful molecules called free radicals , as well as toxic chemicals and pollutants like cigarette smoke.

Epidemiologic evidence suggests that higher consumption of fruits and vegetables is associated with lower risk of most types of cancer, perhaps, in part, due to their high vitamin C content [ 6 , 7 ]. Vitamin C can limit the formation of carcinogens, such as nitrosamines [ 7 , 78 ], in vivo modulate immune response [ 7 , 9 ] and, through its antioxidant function, possibly attenuate oxidative damage that can lead to cancer [ 6 ].
A few studies in humans have examined whether bioavailability differs among the various forms of vitamin C. In one study, Ester-C® and ascorbic acid produced the same vitamin C plasma concentrations, but Ester-C® produced significantly higher vitamin C concentrations in leukocytes 79 hours after ingestion [ 67 ]. Another study found no differences in plasma vitamin C levels or urinary excretion of vitamin C among three different vitamin C sources: ascorbic acid, Ester-C® , and ascorbic acid with bioflavonoids [ 66 ]. These findings, coupled with the relatively low cost of ascorbic acid, led the authors to conclude that simple ascorbic acid is the preferred source of supplemental vitamin C [ 66 ].
Futher their diets were always based on small amounts of salted beef, and heavy in flour based hard and soft tack, suet puddings, and whenever they could get fresh meat, all signs of scurvy disappeared.
