Having a weak immune system leads to digestive issues and frequent infections that can cascade into other illnesses. Breaking this cycle can seem hopeless, especially if you have been dealing with it for a long time. Immune system issues may be the result of a serious condition that requires medical intervention, but if there is no specific medical reason for your recurring ailments, you might be able to activate your immune system and give it that extra boost in your favor.

When it comes to boosting your immune system, vitamin C or ascorbic acid immediately comes to mind, and there’s a good reason for that. The results of a study on reconstituting the severely weakened immune systems of patients after chemotherapy indicate that ascorbic acid enhances natural killer cells or NK cells. These lymphocytes induce apoptosis of infected cells with the help of special proteins and proteases.
