Life Extension Neuro-Mag Magnesium L-Threonate
Brand: Life Extension · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Life Extension Neuro-Mag Magnesium L-Threonate is a targeted supplement designed to support brain health, but the specific data provided focuses on the ingredient calcium, not magnesium. We cannot confirm the benefits of this specific magnesium form from the available data. For calcium, which is a different mineral, the data supports its role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your nerves. It supports bone density and mineral deposition, and also helps your muscles relax and your nerves send signals properly [NIH ODS]. For the specific magnesium L-threonate in this product, detailed mechanism data is not available.
Safety profile
FDA received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine 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]. Data on side effects specific to this product is not available.
Our recommendation
We recommend you consult with your healthcare provider before starting this supplement, as the data provided does not include specific benefits or risks for magnesium L-threonate. If you are considering a calcium supplement, be aware it can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. A personalized assessment is essential for safe and effective use.
