Swanson Premium Brand Magnesium (Lactate) 84 mg
Brand: Swanson Premium Brand · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Swanson Premium Brand Magnesium (Lactate) 84 mg is a specific form of magnesium that may help support muscle relaxation and nerve function, but the data provided is limited. For this product, we only have information on calcium from the NIH ODS, not on magnesium itself. Our assessment is that you should be cautious, as the safety and efficacy data for magnesium lactate specifically are not available in the provided materials. Data not available for magnesium-specific benefits.
How it works
While the provided data focuses on calcium, not magnesium, it describes how minerals work in the body. For calcium, it acts as a master regulator for bone mineralization and neuromuscular relaxation, supporting bone density and nerve signaling [NIH ODS]. For magnesium, a similar role is expected—helping muscles relax and nerves function—but this is not confirmed by the data provided. Data not available for magnesium mechanism of action.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific data for this magnesium product is not available. For calcium, the NIH ODS notes that high levels 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effects of magnesium lactate.
Our recommendation
We recommend you do not use this product based solely on the data provided. Since the data does not include magnesium-specific benefits, side effects, or study citations, you should seek a supplement with more evidence. If you are considering magnesium for muscle relaxation or nerve health, look for a product with a full data profile. Always consult your healthcare provider before starting any new supplement.
