Supplements are products designed to supplement your current diet and come in various forms such as pills, tablets, capsules, powders, and liquids. They have been around for a long time and were initially discovered in food products. However, not all supplements work the same way. Some of the first fat loss supplements were tapeworm eggs, which people would take to lose weight. Supplements are not super important, but they can play a vital role in situations where you may not be getting enough nutrients from whole natural foods. For example, when you reduce your calories, you may also be reducing your nutrient intake, and when you increase your strength, you may be increasing your nutrient requirements. In such cases, supplements can help make up the difference. However, supplements are not the answer to your health and fitness goals, unless you have an actual nutrient deficiency.
