Food or food component that is considered to have a beneficial effect on the consumer's health. Definitions differ between countries. Nutraceuticals can be naturally occuring components of certain foods, which are often consumed in a concentrated medication-like form (e.g. as tablets, pills, or concentrated liquid). Examples are omega-3-fatty-acids or beta-carotenes. Nutraceuticals can also be whole foods, which are thought to have health benefits, e.g. certain herbs, garlic, chia seeds. Generally, nutraceuticals are consumed or fed to maintain good health, rather than to treat diseases.
