Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, based on the data provided, we cannot confirm the specific benefits of magnesium L-threonate for cognitive function, as that information is not available in the supplied data. Our assessment is that calcium is the primary ingredient with verified data, and you should be aware of its potential risks before taking this supplement.
How it works
Calcium supports your body through bone mineralization, helping to maintain bone density and mineral deposition. It also plays a role in neuromuscular relaxation, aiding in muscle relaxation and nerve signaling [NIH ODS]. The specific mechanism of magnesium L-threonate is not detailed in the provided data.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include poor muscle tone, poor kidney function, 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 medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on side effects specific to magnesium L-threonate is not available.
Our recommendation
Given the potential risks associated with high calcium intake, we recommend you consult with your healthcare provider before starting this supplement, especially if you take any medications listed above. Do not exceed the recommended dose on the label. Data on the optimal dosing and benefits of magnesium L-threonate is not available, so rely on professional medical advice for your individual needs.
