Also of great importance as an antioxidant is vitamin E, which ideally should be taken along with vitamin C in a ratio of roughly 1 part E for every 3 1/2 parts C. In long-lived wildlife, the ratios of these two antioxidants are typically found to be between 1:4 and 1:6. However, most animals have very low body fat—roughly 2–4%, which is far lower than that of humans. Hence the recommended ratio of 1:3 1/2. (It’s interesting to note that vitamin E and ascorbyl palmitate together constitute a good system for protecting foods from oxidation.)
