What are the best supplements to prevent getting sick


To prevent getting sick, recommends the following strategies and supplements:

  1. Vitamin D: A dosage of 1000 to 2000 IU of Vitamin D per day is generally considered safe and can help maintain healthy levels in your system, which is linked to improved immune system function and a decreased susceptibility to acute respiratory tract infections. It's important to note that while Vitamin D supplementation has shown to reduce the risk of such infections, the effect size can vary from small to moderate. For personalized dosage, measuring your vitamin D levels is advised, as some individuals may require higher doses for optimal health 1.

  2. Zinc: Supplementation with zinc can be effective in combating colds, especially if taken in doses of 100 milligrams or more. Such doses should be divided or taken with food to prevent gastric distress. Zinc is reported to help reduce the duration and intensity of cold symptoms 2.

  3. Sunlight and Lifestyle: Regular exposure to sunlight can increase Vitamin D levels naturally, which along with its benefits for the immune system, also promotes healthy levels of other hormones like cortisol, dopamine, and serotonin. Lifestyle factors, including diet and the use of additional natural light sources when sunlight is insufficient, are also important 1.

For the prevention of colds and flu, these supplements, in combination with a healthy lifestyle, offer a robust approach to bolstering your immune system.
