The timing of taking vitamins or natural health products varies depending on the specific product. Some are more effective when taken on an empty stomach, while others should be consumed with food to enhance absorption or prevent potential stomach discomfort. Always refer to the directions on the product label to determine if it should be taken with food. If the label does not specify, you have the flexibility to choose the method you prefer for consumption. However, following the recommended guidelines on the label can help you get the most out of the product and optimize its benefits.
