This is the first in a series of reviews on which products are most likely to help or harm you. I have included all the supplements that I have reviewed. Some people think the list is long, but it's really only a small selection of the most useful ones. Here we go:
Bubonucleotide (L-theanine): Theanine, a amino acid, has been shown to reduce anxiety, depression, stress, and insomnia in laboratory and animal models. It's been used for years as a dietary supplement and has become very popular for its anti-aging effects. Some studies have shown that theanine might also be effective in lowering blood pressure and cholesterol, but there isn't much evidence on how to use it safely. Blueberries: The berries have been shown to increase the flow of blood to the brain, so they may reduce stress. They also help with depression and anxiety, as well as increasing blood flow and oxygen in the brain. Cranberries: Cranberries contain beta-glucan, a naturally occurring substance found in the small intestine. This substance is a precursor to gluconic acid, a compound found in many foods that helps to protect the heart and lungs. One study of 15 healthy people found that it decreased the amount of blood that was in the lungs (and heart).
