what supplement to boost your inmune system would you recommend for a 20 year female? allergies get me really sick and side effects last for months, thank you.
You need to find out first what allergens are causing you trouble, and then deal with them. It is in fact due to the immune system being overly active that you get these allergic reactions, so boosting immune system is not the solution here.
I would be taking a good quality multivitamin like Ruthless 3D. On top of that make sure you are eating your dark green veggies and some citrus. That will give you the extra vitamins and minerals you need for fighting off colds.
