Ayurveda teaches that you should get your daily nutrients from food as much as possible and that you can do this by eating plenty of fresh vegetables, fruits, grains, beans and legumes, nuts and seeds, healthy meats, and seaweed. That said, there are cases in which it makes sense to take vitamin supplements. Vegetarians should take vitamin B12 and possibly vitamin D, since they are missing out on these nutrients by not eating meat. Pregnant women should take extra folic acid. Those with osteoporosis will need to take calcium, magnesium, trace minerals like boron, and other supplements that support bone health. People recovering from a long illness may need to take certain immune-boosting supplements.

It’s important to keep in mind that decades of industrial farming practices have significantly depleted the nutrient content of the soil in which most of our food is grown. Consequently, our food is not as nutritious as it once was. With that in mind, you might be inclined to question the common wisdom that a varied diet fulfills all of our nutritional requirements. If so, you may want to consider taking a broad-spectrum mineral supplement or daily multivitamin. Whenever possible, ingest supplements that are extracted from whole food sources like fruits, vegetables, and grains. These nutrients are more bioavailable than synthetic versions, meaning they are more easily absorbed by your digestive system. The best ways to take vitamins and minerals in are in powdered form, as a liquid concentrate, or as an oil. Avoid taking megadoses or doses larger than recommended dietary reference intakes, no matter how good you think a particular nutrient is for your health. 

Supplementing your diet with vitamins should be the exception, not the rule; they are, after all, called supplements. Nutrients are much more accessible and easily processed by your body when they are consumed via food rather than supplements. Also, a person taking vitamins may mistakenly believe that eating a balanced diet is unnecessary. Remember, no supplement is a magic bullet that does as good a job of meeting your nutritional needs as a diet of healthy whole foods.
