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..

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..

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..

Every day, there are billions of flu-causing viruses and other microbes crawling and creeping around us. They are constantly looking for the perfect opportunity to invade our body and devour our health or even lives. According to the Centers for Disease Control and Prevention (CDC), it is estimated that influenza has resulted in between 12,000 – 61,000 deaths every year since 2010. Although the current atmosphere is frightful, our body is actually created with the power to ward off colds, flu and infections. When our immunity is stimulated and supported with the right nutrients, the d..

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.1-3 But melatonin does much more. Melatonin provides vital support to the immune system, helping coordinate immune responses to defend against a wide variety of threats, including viruses.4-6 Internal ..

Nearly 24% of U.S. adults suffer from arthritis.1 One type, osteoarthritis, is a leading cause of disability worldwide.2 Arthritis was once considered an unavoidable result of wear and tear on the joints. But scientists discovered a way to combat the structural degeneration that marks osteo-arthritis. They did this by supplying the same type of collagen that is the main component of joint cartilage. The name of this compound is undenatured type II collagen. Clinical trials show that this specific collagen can improve joint pain, joint function, and quality of life, while helping..

Scientists studying the diets of our ancestors have made an interesting and shocking finding: In ancient times, people ate a diet that adhered much more closely to an ideal, balanced 4:1 ratio of omega-6 and omega-3 fatty acids.1 Today, the average intake of omega-6s is vastly higher. The amount of omega-6 fats ingested compared to omega-3s has surged as high as 20 to 1.1 This imbalance in our fatty-acid intake is a contributor to the most common age-related diseases. The problem with modern diets is excess consumption of omega-6 fats and deficient intake of omega-3s. A combined..

Elevated blood levels of uric acid are present in about 21% of Americans.1 People frequently associate high uric acid levels with gout, yet many symptom-free individuals have elevated uric acid for years before getting their first gout attack.2 Gout is not the only manifestation of elevated uric acid blood levels. When uric acid levels are higher than optimal, there’s also an increased risk of coronary artery disease, cerebrovascular disease, and early mortality.3-6 Excess uric acid can be caused by aging, adverse lifestyle habits, hypertension, diabetes, kidney problems, and ob..

Cardiovascular disease remains the leading cause of death in the U.S. and worldwide.1,2 It’s been that way despite billions of dollars spent developing drugs and surgical treatments. But there’s a simple way to help lower the risk: increasing intake of the mineral magnesium.3,4 One large epidemiological study of older men showed that those with the highest magnesium blood levels had a 44% lower risk of heart failure than those with the lowest magnesium levels.5 Most Americans fail to consume enough magnesium. An estimated 64% of all men and 67% of all women are magne..

Polyenylphosphatidylcholine (PPC), also referred to as phosphatidylcholine, is a fat-soluble nutrient with many health-promoting benefits. These include protecting the liver, sustaining cardiovascular health, and supporting nervous system and gastrointestinal function. Dietary sources of PPC include soybeans, liver, oatmeal, cabbage, cauliflower, egg yolks, meat, and vegetables. PPC is an essential component in each of the body’s cell membranes, the dynamic surfaces on which cells carry out many of their biochemical activities. PPC is a phospholipid rich in polyunsaturated fatty acids..
