Peptides are smaller versions of proteins. Many health and cosmetic products contain different peptides for many uses, such as their potential anti-aging, anti-inflammatory, or muscle building properties. Recent research indicates that some types of peptides could have a beneficial role in slowing down the aging process, reducing inflammation, and destroying microbes. People may confuse peptides

Acetylcholine is a chemical messenger, or neurotransmitter, that plays an important role in brain and muscle function. Imbalances in acetylcholine are linked with chronic conditions, such as Alzheimer’s disease and Parkinson’s disease. Acetylcholine was the first neurotransmitter discovered. Imbalances in levels of acetylcholine play a role in some neurological conditions. People who have Alzheimer’s disease
