As with everything in the field of health, there's some debate around whether we need to supplement at all. Obviously there's money on both sides of the argument: the natural health industry wants you using them and believes they'll keep you well; the medical industry prefers you use pharmaceutical drugs; and many people just think we should be able to get all our nutrients from food.
Here's my position: Nutrients run our bodies, so we definitely need them, and no pharmaceutical can ever pretend to provide nutrition. Pharmaceuticals stimulate or block certain chemical reactions to alter how we feel, but they aren't the building blocks of the body. I don't think anyone can argue this point.
So ideally we get a lot of nutrients from our food, and in the best circumstance, we would get all of our nutrients from our food and would never need to supplement. But we live in a more polluted world than ever, and are our diets aren't varied enough to cover all our nutrient needs, and our soil is measurably missing many of the nutrients it once had. (Even farmers add supplements to the feed for their animals; their livelihood depends on having healthy animals, and they know this is necessary.) Plus, those on serious supplement regimens can see serious improvements in their health.
So to me, common sense suggests that we need to supplement even a healthy diet, and the less healthy we are, the more we may need to supplement to get back to good health. Still, these should be considered supplements -- additions to healthy eating choices, as I've described on the diet page.
Below, I've written out what I think are the essential supplements. After you get the basics, you can look at additional options if you like.
There are thousands of specialty supplements, and some may be useful for specific health concerns. But again, addressing the needs of the general population, this is what I recommend everyone take:
Please remember a couple points: 1) if you are on medications or have specific health concerns, check with your health / medical professional; 2) if you're regularly eating Yevo foods, you're probably already getting most of the basics shown here, not including iodine or prebiotics.
I appreciate that people will argue about the best delivery systems, and whether you should replace meals with shakes or stick with capsules, and so on. I won't argue all this, because it won't end the debates. In general, I would recommend avoiding the products you find in most drug stores or grocery stores and look to those you find in health food stores or those I've recommended above.
