Health Benefits of Nutritional Supplements



The importance of nutrition for human health has long been known. Prior to 1960, interest in this field focused mainly on the prevention of acute nutrient deficiency diseases, such as scurvy, rickets, and pellagra. Some 50 essential nutrients (vitamins, minerals, antioxidants, cofactors, essential amino acids, and essential fatty acids) were identified. Recommended daily intakes for those nutrients were also developed. The recommendations proved valuable in eliminating acute nutrient deficiency diseases.

During the past decades, focus has shifted to the role of diet and nutrition in long-term health. Nutrition has shown to play a role in the long-term health of heart, bones, joints, eyes, nervous system, and immune system.

Unfortunately, these associations are difficult to study, in part because of the timeframes involved. Many of these interactions take decades (or lifetimes) to study. It is very difficult to conduct research spanning more than several years in length. Despite this, advances in epidemiological and clinical research have uncovered a great deal of information about the impact of diet and nutrient intakes on long-term health.

In recent years, researchers have paid more attention to nutritional supplements as possible components of a healthy diet. These studies have used a wide variety of research methods and have produced positive and negative results. Some supplementation has become an accepted part of modern healthcare practices. This includes, for example, the role of calcium and vitamin D supplements in maintaining healthy bone density and the role of folic acid supplements in preventing certain birth defects. In other areas (like the role of antioxidant supplementation in heart health), results have been less consistent, and firm conclusions remain controversial.

USANA® MagneCal D™
Build a strong foundation for your active life with a carefully balanced bone-building supplement.*

Make no bones about it, calcium, magnesium, and vitamin D are all vital to your everyday health. The good news is that dietary surveys show most people are generally consuming more calcium now than in recent decades. The bad news? Overall calcium consumption is still falling a bit short of optimal dietary amounts. And the majority of people fall significantly far below adequate intakes of magnesium or vitamin D.*

By consuming more calcium than magnesium, you may have an imbalance that, according to researchers, could negatively impact your long-term health. The Center for Magnesium Education and Research recommends something close to a 2:1 ratio of total calcium to magnesium per day—from food and supplements.

Vitamin D is another nutrient that continues to show benefits up to as much as 125 mcg per day. And it has repeatedly been shown that calcium is most beneficial when taken with vitamin D and magnesium.*

Long story, short: you probably need more magnesium and vitamin D than you’re already getting. But not necessarily a lot more calcium.*

Fortunately, supplementing these key nutrients is easy. And, it’s one of the best ways to reach more ideal levels. However, most calcium supplements provide much more calcium than magnesium—making the imbalance worse. USANA® MagneCal D™ is different. It offers a 1:1 ratio of magnesium and calcium.*

This equal ratio means you get more magnesium—but not a lot of extra calcium—to help you get closer to the overall 2:1 ratio. Plus, you get advanced levels of vitamin D. Together, this formula delivers a better balance that matches today’s dietary needs.

MagneCal D can help you maintain many aspects of good health.* Here are just a few:

Strong, mineral-rich bones and teeth*
Healthy muscle and nerve function*
Energy metabolism*
Cardiovascular health*
The kosher formula is an excellent complement to the USANA® CellSentials™. Together, they will help give you optimal amounts of nutrients with excellent absorption and maximum effectiveness.*

Beyond the added vitamin D, the key to BiOmega’s effectiveness is the amount of long-chain EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) it contains. Both EPA and DHA have been extensively studied and found to provide different, important actions in the body. And the long-chain forms of omega-3s are more potent than other, short-chain fatty acids. This means you don’t have to consume as much to get all the great health benefits.*

Reducing the Negative Health Effects of Air Pollution

Take a deep breath. It’s a good idea for your mental health. But when the air isn’t clean, should you feel great about breathing deeply? How does air pollution impact your health?

The simple answer is that air pollution is a major human health concern and is a risk factor for several health conditions. The most common health effects of air pollution are respiratory ones, such as coughing, asthma, and stressing existing respiratory health issues. In some cases, air pollution can be related to major cardiovascular issues.

The most common causes of environmental air pollution include power plants, manufacturing facilities, fuel-burning heaters, automobiles, and wildfires. Despite increasing government regulations to reduce emissions and modern, cleaner combustion devices, air quality in many areas continues to be poor. This isn’t limited to just major cities either, the World Health Organization (WHO) estimates that 92 percent of the world’s population lives in areas with poor air quality.

One of the most dangerous forms of air pollution are fine particles, known as PM2.5, with a diameter of less than 2.5 micrometers. Among the potential negative effects of these particles is that exposure can result in epigenetic alterations (the switches that turn on different aspects of your genetic code) to DNA that could damage health.

How B Vitamins Might Help Protect Your Health from Bad Air
You can’t stop breathing. Ultra-filtration may not be financially doable. So, what’s the solution to help mitigate the impact of air pollution on health?

Turning to your diet may be one answer. Animal models have already shown that the administration of B vitamins (and other methyl-rich nutrients) can help reduce the negative effects of environmental stressors on DNA.

A study published in PNAS used B vitamins to determine if the results previously observed in animals was relevant in humans. During treatment individuals were given 2.5 mg/day folic acid, 50 mg/day vitamin B6, and 1 mg/day vitamin B12. The individuals were exposed to PM2.5 to determine if epigenetic alterations were mitigated by B vitamin supplementation.

Following exposure to the PM2.5, different locations of the subjects’ DNA were measured to determine the extent of DNA changes. Supplementation with the B vitamin lessened DNA changes in the top 10 locations by 28-76 percent compared to placebo.

More research in this area needs to be conducted. But this study demonstrates supplementation with B vitamins may help protect against the negative effects of air pollution.
