Nutricost Magnesium Citrate 210 mg Unflavored
Brand: Nutricost · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that magnesium citrate is a well-absorbed form of magnesium commonly used to support muscle relaxation and nerve function. For the specific product, Nutricost Magnesium Citrate 210 mg, our assessment is that it may be a useful option for individuals looking to supplement their magnesium intake. However, we must note that data on the exact benefits of this specific branded product is limited to the general properties of magnesium citrate. The data provided does not include specific studies on magnesium itself, so we must rely on general mineral principles.
How it works
Think of magnesium as a key regulator for your body's electrical and muscular systems. While the data for this product focuses on calcium, the general role of magnesium citrate is to support neuromuscular relaxation and nerve signaling, similar to calcium's role in bone mineralization and muscle relaxation. Magnesium helps your muscles relax after contraction and supports a calm nervous system [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports for all supplement products combined. Data not available on side effects specific to magnesium citrate. However, based on general mineral safety, high levels of minerals like calcium can cause poor muscle tone, constipation, nausea, and abnormal heart rhythms [NIH ODS]. Magnesium citrate is known to have a laxative effect, which can be a side effect at higher doses. Always start with a low dose to assess your tolerance.
Our recommendation
We recommend starting with one capsule (210 mg) daily, taken with food and a full glass of water to minimize digestive upset. Because magnesium citrate can be quite absorbable, this dose may be effective for mild deficiency or general wellness. However, data not available on the specific interactions for this product, so be cautious if you take medications like bisphosphonates or tetracycline antibiotics, as minerals can reduce their absorption [NIH ODS]. Consult your doctor before starting any new supplement, especially if you have kidney concerns.
