Natural food supplements include many different products—from fish oil to bran and garlic—and are composed of foods that provide a multitude of health benefits. They can be high in certain nutrients, aid in digestion, or offer other benefits.
Good supplements come in every form—from jellies to powders to crackers and capsules. Read labels carefully for information on storing and using the products. Their potency may be affected by temperature or shelf life. The book Prescription for Nutritional Healing offers a broad overview of food supplements.
This is one area in which you must be an informed consumer. There are unscrupulous manufacturers who make claims about food products that are not true. Do your own research and talk to a health care provider who is familiar with such products (not all doctors are).
