A powerful support for the common cold, you can take up to 2000mg vitamin C, four times daily. Fresh squeezed lemon is also a good way to naturally supplement vitamin C levels. The benefits of drinking lemon juice mixed in water go beyond the naturally occurring vitamin C. Lemons aid the body in purifying the lymphatic system, which is a crucial component of fighting off colds. . . ... Boosting up on Vitamin D helps to prevent colds and flu. This may be related to the necessary role this vitamin plays in the protection and lubrication of many of the body’s principle organ systems. It also boosts cellular growth and immune cell activity, and lowers the inflammatory response. I recommend 15 minutes daily of natural sunlight, consuming more foods with vitamin D and possibly taking a vitamin D3 supplement. ..............................................................................................................................................
