  • Nutraceutical products are almost always obtained from plant or animal sources.
  • In general, nutraceutical doses are much higher than the amount that could be obtained from food sources.
  • These products have the potential to provide significant benefits and possible risks. Use nutraceuticals with caution if you are taking pharmaceutical medications (prescription and others), herbs, or other natural products. Always review for potential nutraceutical-drug, nutraceutical-herb, and nutraceutical-natural product interactions with your healthcare provider.
  • Amino acids are the building blocks for proteins. There are two categories of amino acids: Essential and nonessential. The essential amino acids must be obtained from food or dietary supplements, while the body can usually make the nonessential amino acids.
