We recommend taking vitamins along with your heaviest meal for optimal absorption (usually lunch or dinner) at a time when it’s convenient for you. Taking them at the same time each day will help you develop a consistent routine. Although it is safe to take all your dietary supplements at once, there are some exceptions, such as melatonin, which should only be taken before bed. These will be packed separately, however, so there is never any confusion.Because no two people are alike, if you are taking any medications you should be aware that potential drug-nutrient interactions may occur and are encouraged to consult a health care professional before using this product. Those who are pregnant, or nursing should also consult with their physician before use.
