Brain-Protective Effects of Green Tea
July 2021 Scientists are finding that compounds found in green tea can bolster and protect brain health.1-4 One meta-analysis found that the rate of cognitive disorders was 35% lower in people who regularly drank tea.5 Parkinson’s disease risk was reduced by 26% for every two cups per day of tea consumed in another study.6 The healthful compounds found in green tea work in several different ways to boost brain function and guard against cognitive decline.     For those who do not consume enough gre..

Nutrients that Strengthen Immune System
Common colds are the most common human infection. The flu is less common but far more severe. Here’s the good news: In the early stages of a cold or flu, it is still possible to change the course of the illness. The immune-supporting nutrients bolster your body’s defenses, helping to reduce both the severity and duration of the illness. In human studies: Zinc lozenges reduce the duration of colds by up to 44% and the severity of symptoms by as much as 50% when initiated soon after symptoms first appear,2 Elderberry extract resolves upper respiratory symptoms up to ..

NAD+ Promotes Stem Cell Renewal and Regenerates Mitochondria
Life Extension® receives many inquiries about stem cell infusion therapies offered in the United States and other countries. Our current view from small human trials is that there may be a benefit to infusions of exosomes that are naturally secreted from healthy stem cells. Stem cell exosomes have regenerative properties that help restore functional cells needed to maintain tissue and organ viability. Overlooked when considering exosome treatments is the ability to rejuvenate existing stem cell pools u..

Fight High Cholesterol Levels at the Root Causes
Cardiovascular disease is the second leading cause of death: a heart attack occurs every 5 seconds, a stroke every 6 seconds, 17 million people die each year from heart disease. According to the World Health Organization, half of deaths and disability cases resulting from a heart attack or stroke could be prevented by acting on cholesterol levels. What is Cholesterol? Cholesterol is a specific form of lipid or fat, partly made by the liver (endogenous), and partly provided by the diet (exogenous). It is essential to the body as it is a major component of cell membranes to ensure thei..

Enhancing the Life Saving Benefits of Vitamin K
Recent studies have expanded our understanding of vitamin K. We've long known it to be essential for bone density along with heart health.1-3 One study found that people aged 55 and older with the highest intake of vitamin K had a 57% lower rate of death from coronary heart disease over 10 years—and a 26% lower rate of death from any cause.4 A 2017 study showed that people with the highest intake of vitamin K had a 22% lower rate of bone fractures.5 More ways..

Turn on Your Body’s Youth Switch
An enzyme called AMPK is one of the body’s most powerful anti-aging tools. AMPK promotes regenerative pathways and acts in every cell to restore youthful function.1 Over time, AMPK activity declines. The result is accelerated aging. AMPK activation in animal models contributes to longer, healthier lifespans.1-3 Two low-cost nutrients have demonstrated potent AMPK-activating effects. By taking steps to activate AMPK, it becomes possible to enhance youthful functionality throughout our body. AMPK: A “Youth Switch” Note: AMPK is the acronym for: adenosi..

Nutrients to Charge up Brain Function
Nootropics are compounds that enhance cognition and facilitate learning. They differ from nutrients that protect against brain aging. Nootropics are for people seeking to improve brain processing speed and mental alertness. Nutrients with nootropic properties have become popular for people of all ages to improve thinking speed and accuracy. Nootropics Tune Up Your Mind Nootropics are a different type of brain and cognition supplement. Their goal is to boost cognitive performance now. Nootropics are meant to improve and recall recent and old memories. Nootropic compounds bo..

Fish Oil that is Good for You and the Ocean
Oceans are teeming with life, beauty, and mystery — magnificent worlds that are so different from our lives on land. The ocean is said to be Earth’s life support: we rely on it to help us regulate the climate, absorb CO2, and provide the primary protein for 3 billion people around the world. Many of us enjoy eating fish and have access to many kinds of fish at the market and when dining out. We may also choose to supplement our diets with fish oil—perfect for people who don’t love to eat fish but want its benefits. Unfortunately, poorly managed and industrial fish..

Vitamin C: Critical Role in Immune Health
We’ve heard it all our lives: Vitamin C fights colds. That’s partially true. Some human studies show that taking vitamin C can lessen the severity and duration of the common cold.1 What’s irrefutable is the role that vitamin C plays in maintaining immune function.2-4 The ABCs of Vitamin C Vitamin C is an essential nutrient in humans.2 Without it we die. Humans don’t internally produce vitamin C like most animals. It must be obtained from diet or other external sources. Severe vitamin C deficiency—medically known as scurvy2—causes..

How Ionic Zinc Can Stop Colds Fast
Common colds are the most common human infection.1 Based on research published in the 1980s, many people know to start popping zinc lozenges. But not all zinc is the same. Many cold lozenges feature different forms of zinc that are not the most effective choice. The specific kind of zinc lozenge that has shown the most consistent benefit is one that slowly releases ionic zinc. Taken at the earliest sign of symptoms, it can protect against a cold developing and shorten the duration of a cold by seven days.2,3 What’s critical is to initiate zinc lozenges as soon as the fi..
