It really varies from person to person. According to Dr. Carolyn Dean, author of “The Magnesium Miracle”, “it is recommended to take magnesium supplements between meals for optimal absorption. Magnesium needs stomach acid to be absorbed. After a full meal your stomach acid is busy digesting food and may not be available to help absorb the magnesium, where if you take it with food it may neutralize stomach acid and impair digestion.”
If you are wondering whether you should take Natural Calm in the morning or at night, it depends on what you are hoping to get from the product. Some people may feel sleepy after drinking Calm due to its naturally relaxing effect and thus prefer to take it at night, whereas others may prefer to take it in the morning to ease feelings of anxiety, help combat a headache or simply start the day calmfully.
