Solgar Magnesium with Vitamin B6
Brand: Solgar · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product is a combination of two well-studied nutrients, but you need to understand that the data we have is for each ingredient individually. For calcium, the primary mineral in this product, the evidence strongly supports its role in bone health. However, we must be clear: the data provided does not include specific studies or side effect reports for magnesium or vitamin B6, so we cannot assess the complete formula. Our assessment is that the calcium component is well-documented, but the full product profile is incomplete from the data you've given us.
How it works
Think of calcium as a structural builder and signal regulator for your body. It supports bone mineralization and density by depositing minerals into your skeleton [NIH ODS]. At the same time, calcium is essential for neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS]. This dual role makes it critical for both your skeletal strength and your day-to-day muscle function.
Safety profile
Safety data for the specific product is not available. However, based on the calcium data, you should be aware of important risks. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA has received a total of 592,059 adverse event reports for this product's ingredient category, though specific report counts for each side effect are not provided [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you proceed with caution. Before taking this supplement, you should review your total calcium intake from all sources, including food and other supplements. Because calcium can interact with common medications, you should discuss this product with your doctor or pharmacist if you take any prescription drugs, especially those listed in the safety profile. Data for the magnesium and vitamin B6 components is not available, so you cannot rely on this product for those specific benefits. Our confident recommendation: prioritize getting your calcium from food sources first, and only use this supplement under professional guidance to avoid exceeding safe intake levels.
