Trace Minerals Research Fast-Absorbing Liquid Magnesium 300 mg Tangerine
Brand: Trace Minerals Research · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
Our assessment: This liquid magnesium supplement provides 300 mg per serving, which is close to the daily recommended intake for adult males (400-420 mg) and exceeds the RDA for adult females (310-320 mg) [NIH ODS]. The tangerine flavor may improve compliance for those who dislike pills, but the key question is whether the "fast-absorbing" claim is supported by the data. Data not available on specific absorption rates for this formulation compared to standard magnesium supplements.
How it works
Magnesium is a critical mineral involved in over 300 enzymatic reactions, including muscle contraction, nerve function, blood glucose control, and blood pressure regulation [NIH ODS]. You need adequate magnesium for energy production, protein synthesis, and maintaining healthy bones and teeth. The liquid form may be easier for you to take if you have difficulty swallowing tablets, but the body absorbs magnesium from food and supplements through the same intestinal pathways [NIH ODS].
Safety profile
FDA received 694 adverse event reports for magnesium supplements overall [FDA data]. Common side effects include diarrhea, nausea, and abdominal cramping, especially at doses above 350 mg daily from non-food sources [NIH ODS]. Report counts from FDA data: 694 total adverse events for magnesium supplements [FDA data]. The liquid form may cause looser stools more quickly than tablets because it enters the digestive system faster. Do not exceed the tolerable upper intake level of 350 mg from supplements unless under medical supervision [NIH ODS].
Our recommendation
Data not available on whether this specific product is "fast-absorbing" compared to other magnesium forms. For general health, start with one serving (300 mg) daily, but note this already exceeds the supplemental upper limit of 350 mg when combined with dietary intake [NIH ODS]. Choose this product if you prefer liquids and tangerine flavor. Monitor for digestive upset. If you experience diarrhea, reduce to half a serving or switch to magnesium glycinate [NIH ODS].
