NAC (N-acetyl-L-cysteine) helps prevent viruses and bacteria from adhering to the lining of the lungs. Data show that NAC reduces excess airway mucus, lowers inflammation, supports pulmonary function, and inhibits infectious colonization.

In a clinical trial at UCLA School of Medicine, researchers found that the prebiotic XOS (xylooligosaccharide) increased the beneficial bifidobacteria for overall health.

The enzyme superoxide dismutase (SOD) is one of the body’s foremost antioxidant defenses, reducing free radical damage associated with atherosclerosis, stroke, and arthritis. New bioavailable forms of SOD offer superior protection against oxygen free radicals.

Many people consider their pets to be integral parts of the family. Yet their nutrition is not always properly addressed. Here, we highlight the essentials about how to keep your pet healthy.

Melatonin has been shown to help fight cancer, boost immune function, and enable better sleep in some people. This pineal hormone is secreted abundantly in youth but declines with normal aging. 

Melatonin has long been thought of as the “sleep hormone.” It regulates circadian rhythms, the body’s internal biological clock, which can improve sleep patterns. That’s important for optimal health. Inadequate sleep has a well-documented negative impact on immune health, increasing susceptibility to infectious diseases and cancer. But melatonin does much more.

The amino acid derivative N-acetylcysteine protects against a broad array of environmental toxins, helps boost the body’s immune system, and confers other health-promoting benefits.

Your body releases the hormone cortisol in response to stress. Excess cortisol from chronic stress is linked to everything from diabetes to bone loss, weight gain, and sleepless nights. A low-cost supplement called rhodiola combats cortisol’s lethal effects.

Despite their predilection for fatty food, the French have a relatively low risk of dying from heart disease. Wine consumption may explain this “French paradox.” New research reveals that grape plants are loaded with “super-antioxidant” phytocompounds such as quercetin, resveratrol, and others that may benefit human health in myriad ways.

Is soy safe? A vocal minority has fueled a “controversy” of misinformation that surrounds this nutritional powerhouse. A review of the published scientific literature uncovers a wealth of studies validating soy’s broad-spectrum benefits, from cardiovascular disease and cancer prevention, to helping to maintain bone density.

A recent review reveals that lycopene shields against environmental and food toxins. Individuals with the highest lycopene concentrations have a 37% lower mortality risk.

Fitness enthusiasts have long prized branched chain amino acids (BCAAs) for their power to boost strength and performance. A newly published study may now give longevity enthusiasts a reason to as well: in an animal model, BCAAs increased life span in part through mitochondrial biogenesis—the spontaneous growth of new mitochondria.

Deep vein thrombosis, caused by sitting too long, kills over 100,000 Americans each year. A human study shows that nattokinase and French maritime pine bark improve circulation in the lower legs, lessen leg swelling, and reduce thrombosis (abnormal clot) formation.

With age, the insides of our cells accumulate damaged proteins and other debris that impair youthful function. Humans are equipped with a built-in process that removes these toxic waste products to make room for healthy internal regeneration. This natural, cell housekeeping process is called autophagy.

Using deep-learning artificial intelligence, scientists have identified three plant-based nutrients that can help reverse age-related damage to our existing pool of stem cells.

Low-level inflammation is an underlying factor for six of the ten leading causes of death. Studies have shown that Boswellia extract significantly improved arthritis patients’ pain and function in just seven days while suppressing causative agents involved in chronic inflammation.

Two active forms of vitamin B12 offer support to the aging brain. Preclinical data shows one of the forms protects dopamine levels. People with vitamin B12 deficiencies frequently suffer anemia, weakness, and fatigue. But there are more dangerous effects. Low vitamin B12 levels have been associated with progressive brain atrophy (shrinkage). One study found an astounding 517% greater rate of brain volume loss in people with lower vitamin B12 than those with higher B12 levels.

Homocysteine is an amino acid made from a common dietary amino acid, methionine, that inflicts damage to the inner arterial lining (endothelium). Elevated levels of homocysteine have been associated with many diseases, including: cardiovascular disease, congestive heart failure, stroke, migraines, age-related macular degeneration, hearing loss, brain atrophy, Alzheimer disease.

A study showed that lozenges containing zinc acetate are best at curbing a cold and shortening its duration. Zinc lozenges are not meant for everyday use. Common colds are the most common human infection. 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.

Lactoferrin, a protein found in mother’s milk, shows antiviral activity in preclinical trials. It impedes viral binding to cell membranes, while activating immune defenses.

While medical science is diligently working on the development of an effective treatment, it may be prudent to learn about some protective measures now, and to become informed concerning potential nutritional therapies.

The Life Extension Foundation offers several hundred products. Thinking about the offer of the LEsupplements.com portal I focused on the most advanced ones and these formulas which are dedicated to specific diseases.
