Swanson Ultra Albion Chelated Magnesium 133 mg
Brand: Swanson Ultra · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Swanson Ultra Albion Chelated Magnesium 133 mg provides a well-absorbed form of magnesium. However, based on the data provided, the primary ingredient in this product is calcium, not magnesium. For calcium, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. You should be aware of the specific risks and interactions associated with calcium supplements.
How it works
Think of calcium as a key structural component for your bones and teeth. It supports bone density and mineral deposition [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, helping with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, some research suggests that high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are taking this product for calcium, check your total daily intake from all sources. Be aware of the potential side effects and medication interactions listed above [NIH ODS]. For a magnesium-only product, data was not available to make a specific recommendation. Consult your healthcare provider before starting any new supplement, especially if you take prescription medications [NIH ODS].
