Magnesium is undoubtedly an essential mineral that the body requires to perform several critical biological functions. However, simply mindlessly consuming magnesium supplements will not give any result. One needs to be careful while taking magnesium supplements. When taking magnesium supplements, certain other supplements can interfere with magnesium absorption, interact negatively, or even cause an overload of certain minerals in the body.
Here are three supplements to avoid when you’re on magnesium, with explanations for each:
Calcium can compete with magnesium for absorption in the body
Magnesium and calcium are essential minerals often recommended together for bone health, but they can compete for absorption in the body. Taking them together, especially in large amounts, may reduce how effectively either mineral is absorbed and utilized. Magnesium and calcium share common pathways for absorption in the intestines, which can cause them to compete if taken simultaneously. When this happens, you may not get the full benefit of either supplement, which can lead to deficiencies over time.

Do you consume magnesium supplements daily?
To minimize this risk, several health experts suggest that the intake of calcium and magnesium be separated by at least several hours. Additionally, calcium affects the way magnesium is used within cells, especially with regard to its function in enzymes and muscle relaxation. Therefore, interaction of all the supplements at the same time may cause muscle cramps, fatigue, or even sleep distractions since magnesium is a natural relaxant of muscles and plays a vital role in soothing the nervous system.
Zinc and magnesium have similar pathways
Zinc is another mineral essential for immune function, protein synthesis, and wound healing, but it too can interfere with magnesium absorption when taken together in high doses. Like calcium, zinc uses similar pathways for absorption in the intestines, which means they can compete if taken at the same time. If zinc levels become too high, it may inhibit magnesium absorption and reduce its benefits.
High levels of zinc can also disrupt the balance of other minerals in the body, particularly magnesium and copper. Zinc and copper have an antagonistic relationship, meaning that an excess of zinc can lead to copper deficiency, which in turn can affect magnesium balance. This is why it’s often best to limit zinc supplementation when taking magnesium, especially if you’re on a high-dose magnesium regimen. To prevent mineral imbalance, consider taking these supplements at different times of the day or consulting a healthcare professional to determine the right balance for your needs.
Iron can interfere with the absorption of magnesium
Iron is a crucial mineral for producing hemoglobin and supporting immune health, but it can inhibit magnesium absorption when taken at the same time. Both magnesium and iron require similar transport mechanisms in the gut for absorption, leading to competition if taken together. Studies have shown that iron can impair magnesium absorption in the intestines, especially when taken in high doses.
Iron’s interaction with magnesium goes beyond just absorption. Excessive iron can also increase oxidative stress in the body, which could potentially disrupt magnesium’s role in maintaining cellular health. Additionally, iron supplements are often prescribed for conditions like anemia, where optimizing absorption is essential. Thus, taking magnesium alongside iron could impact the efficacy of iron therapy as well as reduce the absorption of magnesium, leading to deficiencies in both minerals. For those needing both supplements, it’s often recommended to take iron in the morning and magnesium in the evening, or as per medical advice, to avoid potential conflicts.
