Doctor's Best High Absorption Magnesium
Brand: Doctor's Best · Form: TABLET [E0155]
Our assessment
The evidence shows that Doctor's Best High Absorption Magnesium is a well-formulated supplement for supporting magnesium levels. Based on the data provided, magnesium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. We recommend this product for individuals looking to maintain healthy magnesium status, provided you follow dosing guidelines to avoid potential side effects.
How it works
Think of magnesium as a key regulator for your body's relaxation and structural systems. It supports bone density through proper mineral deposition and helps your muscles relax after contraction, which also supports healthy nerve signaling [NIH ODS]. This makes it particularly helpful for muscle cramps, tension, and overall bone health.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific report counts for magnesium alone are not available in the provided data. Potential side effects from high magnesium intake 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]. Magnesium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with the serving size listed on the label and take it with food to minimize stomach upset. If you take any medications, especially antibiotics or thyroid medication, separate your magnesium dose by at least two hours [NIH ODS]. If you have kidney disease or experience any side effects, consult your healthcare provider before continuing use.
