Interaction with nutrients contained in food and drugs
Some of the ingredients in dietary supplements may affect the nutrients contained in your food or medication. Food and supplements may have a negative effect on the absorption, distribution, metabolism and excretion of the drug, which promotes the formation of undesirable health effects. The interaction between the drug and the supplement may have a two-way nature. Examples include preparations containing magnesium, calcium, iron or fennel or dandelion extract that reduce the absorption of tetracyclines from the gastrointestinal tract, affecting the effectiveness of therapy with these drugs.
Antagonism of nutrients
Incorrect proportions between nutrients in the supplement may cause that these components will interact with each other antagonistically, so the action of one will be leveled by the other. This phenomenon occurs with the simultaneous intake of calcium and ironthe presence of calcium in the digestive tract reduces the absorption of iron. Similarly, iron reduces the absorption of zinc and copper. When supplementing nutrients, it is very important to maintain the right proportions between them. You should also take into account the nutrients that are provided with food, which may also interact negatively with the supplement ingredients. There comes the use for the Japan iHerb プロモコードnow.

Of course, this does not apply to everyonepeople with special needs, such as pregnant and lactating women, people using specialized diets, the elderly or those at risk of deficiencies should take appropriately selected supplementary preparations that what a daily diet cannot give. However, if we are not in this group before we spend our money on dietary supplements, let’s think about whether it is better to add them to shopping in the grocery store and take care of a more balanced and varied diet.
