There may a few issues that vegans should be conscious of and one of them is this little piece of advice from a friend who is a biochemistry researcher, who specializes in everything to do with the immune system. I am not using his name, but I've known him for some seventeen years, ever since I once recruited him as the science adviser for a company I was helping to improve their business in the nutritional area. There may legitimately be some nutrition that is harder to get on a plant-based diet than otherwise, so here goes with the advice from my friend:
You can get vegetarian DHA and now EPA supplements that are produced from algae and these are probably the most important nutrients. If we did not get so much omega 6 in our diets (high in all seeds, most all grains and thus corn and soy fed meats and eggs) we could make our own EPA and DHA in our bodies, but the high omega 6 in most diets blocks our ability to make EPA and DHA.Here are some options:
- Vegetarian and Vegan DHA
- Vegetarian and Vegan EPA and EPA+DHA
- Note that some of the products combine both, so you have options galore.
Besides drinking water, the only other supplements that I think are really essential are NAC-Sustain and Glycine, to boost the immune system if you're over 40, since your body's natural production of glutathione (GSH) declines precipitously. Again, this is just my personal observation, built up from experience.
