The number of natural health supplements on the market these days is rivaled only by the spectrum of miraculous benefits they claim to offer. From cultivating a better memory to maintaining peak immune-system strength, it seems Mother Nature holds all the answers to every wellness question ever asked. But do these supplements really work? The only way to determine that is to study the field, identify one that best meets the results you are trying to achieve, and then decide for yourself. Just be sure to consult a physician before starting a regime of any vitamin, mineral, or herbal supplement. In the meantime, here’s a look at three of the best-selling product types on the market and the areas of health they purport to enhance.

Cognitive Function

Before taking any new supplement or vitamin, talk with your doctor first to avoid any potential pitfalls. The Genius Brand

Ever since TV infomercials of the mid-1990s began singing the praises of gingko biloba, the field of natural mood and cognitive enhancers has exploded. Today’s brands include everything from American ginseng to L-Theanine and a host of other unpronounceable ingredients that are said to reduce anxiety, enhance moods, improve memory, and generally make being alive in the modern world a little less frightening than the alternative. Again, consult your physician before taking any supplement.

Cold Suppression

If you’re worried about getting sick during cold season, consider taking a vitamin C supplement. Emergen-C

While it is well-established that vitamins and minerals are best derived from actual food, modern diets make it difficult to get the nutrition we need. As a result, immune-boosting supplements with heavy doses of vitamin C have become very popular during cold and flu season. While the clinical evidence that vitamin C alone can help prevent colds is spotty, there is no doubt that many people swear by natural immune-support products featuring an array of vitamins, minerals, antioxidants, and electrolytes to get them through cold season.

Stress and Wellness

Because physical and mental stress can compromise the immune system, it would seem to follow that anything that helps manage stress would aid fighting off colds. Today’s general wellness formulas often include not only antioxidants such as vitamin C and A, but also a cocktail of stress-fighting herbs known as “adaptogens” that range from tried-and-true ginseng to goji berry, olive leaf extract, and other exotics.
