Are you one of the many people who are taking multivitamins to boost their health? While multivitamins can provide essential nutrients, there is a growing concern about their potential effects on the kidneys.
This has led to many individuals searching for alternatives such as liquid multivitamins. If you’re looking for a liquid multivitamin near me or considering making the switch, it’s important to understand what the science says about the potential risks and benefits.
In this blog post, we’ll take a closer look at whether you may be hurting your kidneys with multivitamins and what you can do to protect your health.
What Are Multivitamins?
Multivitamins are products that contain a variety of vitamins and minerals, such as vitamins A, B complex, C, D, E, and K, calcium, iron, zinc, magnesium, selenium, iodine, and more.
Some multivitamins may also include other ingredients like herbs, amino acids, antioxidants, enzymes, or probiotics. Multivitamins come in different forms such as tablets, capsules, liquids, gummies, or powders.
What Are the Potential Risks of Taking Multivitamins?
While multivitamins can provide many benefits for your health, they can also pose some risks if you take too much or have certain medical conditions.
Some of the potential risks of taking multivitamins for your kidneys are:
Minerals such as potassium, calcium, magnesium, and phosphorus have the potential to affect kidney function.
People with chronic kidney disease who are advised to consume a low-phosphorus diet should be aware that phosphorus is commonly included in multivitamins.
- Excess potassium can cause hyperkalemia, a condition that can lead to irregular heartbeat or cardiac arrest.
- Excess calcium can cause hypercalcemia, a condition that can cause nausea, vomiting, confusion, or kidney stones.
- Excess magnesium can cause hypermagnesemia, a condition that can cause weakness, low blood pressure, or cardiac arrest.
Heavy Metal Contamination
Some supplements may contain traces of heavy metals such as lead, mercury, arsenic, or cadmium that can harm your kidneys.
Heavy metal contamination from supplements is another potential cause of kidney problems.
Certain antibiotics are removed from the body through the kidneys, so taking them with multivitamins can put extra strain on your kidneys.
Penicillin, cephalosporins, and sulfonamides in particular can be harmful to your kidneys. Long-term antibiotic use can injure your kidneys even if you’re otherwise healthy.
Multivitamins containing too much iodine can cause thyroid problems which can affect your kidney function.
Too much iodine can cause hypothyroidism or hyperthyroidism which can lead to fluid retention or dehydration respectively.
Multivitamins containing too much selenium may cause garlic-like breath, hair loss, brittle nails, or a metallic taste in the mouth.
Selenium intake above the upper limit (UL) may also cause severe neurological symptoms, kidney failure, and heart issues.
