For daily immune health maintenance, the suggested serving size is 0.5-1 mL per day. If you are feeling body or immune imbalance, we suggest taking 0.5 mL servings every 3-4 hours. Do not exceed 2 mL per day.  If you have questions about what serving size is best for you, we recommend that you consult with a qualified physician or medical health professional prior to taking SHIELD.
