Teraputics Pure Life Magnesium L-Threonate

Our assessment

The evidence shows that Teraputics Pure Life Magnesium L-Threonate is a dietary supplement that, based on the data provided, contains calcium as its key ingredient. Our assessment is that this product is designed to support bone health and nerve function, but you should be aware of the specific safety considerations and potential interactions associated with calcium supplementation.

How it works

Think of calcium as a builder and signaler in your body. It works through two primary mechanisms: first, it supports bone mineralization, helping deposit and maintain the mineral density in your skeleton [NIH ODS]. Second, it supports neuromuscular relaxation, which is essential for proper muscle relaxation and nerve signaling throughout your body [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplement categories. For this specific ingredient, safety data indicates that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high levels of calcium in the blood and urine include 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]. Data on specific adverse event report counts for this exact product is not available.

Our recommendation

Our recommendation is to speak with your doctor before starting this supplement, especially if you take any of the medications listed above or have a history of kidney problems or heart disease. Start with the lowest effective dose and monitor for side effects like constipation or nausea. Be aware that total calcium intake from all sources (food and supplements) should be considered, as excessive intake carries significant risks [NIH ODS].
