Nature's Way Krebs Magnesium Potassium Complex
Brand: Nature's Way · Form: TABLET [E0155]
Our assessment
The evidence shows that the Krebs Magnesium Potassium Complex from Nature's Way is a supplement intended to deliver key minerals. Based on the data provided, we can only speak to the ingredient calcium, which is a common component in such formulations. Our assessment is that while calcium is essential for bone health, you should be very cautious with supplementation, as high intakes carry significant risks [NIH ODS].
How it works
Calcium acts as a master regulator for your body. It is critical for bone mineralization, helping to deposit minerals and support bone density. Additionally, it plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for products in this category. For calcium specifically, high intakes can lead to serious issues including constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms. Some research also suggests a potential increased risk of heart disease and prostate cancer with high calcium intakes [NIH ODS] [FDA data].
Our recommendation
Data not available for the specific doses of potassium and magnesium in this product. Given the risks associated with calcium, we recommend you do not take this supplement without first consulting your doctor. If you are on medications like bisphosphonates, certain antibiotics, or thyroid medication, calcium can reduce their absorption, so timing doses carefully is critical [NIH ODS].
