What are the best supplements to avoid getting sick?

•  Simple D-3

Simple D-3 helps to support a proper immune response in the body. Healthy prostate, colon and breast tissues are also supported by vitamin D. Vitamins D and K in Simple D-3 (“ “) work as a team. Increasing the amount of vitamin D via supplementation, in the presence of insufficient levels of vitamin K, can increase the risk of inappropriate calcium deposition in the soft tissue (such as arteries and joints) and can have a negative effect on blood vessel elasticity.

•  Simple Immune Support

Simple Immune Support – The herbs, mushrooms, and natural compounds, in Simple Immune Support have been shown to support proper immune functions such as natural killer (NK) cell activity, cytokine synthesis, and expression, as well as the T- and B-cell mediated responses necessary for a strong immune defense. Research suggests that the bioactive constituents from these compounds show significant improvements in conditions such as influenza, respiratory tract infections, cancer prevention, and various viral and bacterial infections.

•  Simple Zinc

Some vitamins/complexes you may be taking have many other ingredients in them you don’t need and that are actually harming your body! Many other companies use so many ingredients in their products as a marketing scheme to make their products “look” better, when “more ingredients” DOES NOT mean “better”. It actually will cause your body more harm than good, because of all the extra work your liver must do to filter them through your body! Also, the other ingredients may be counteracting the effectiveness of the main ingredient you want! Simple and the best ingredients will allow your body to perform at its best!
