Trace Minerals Research Stress-X Magnesium Powder 350 mg

Our assessment

The evidence shows that Stress-X Magnesium Powder provides 350 mg of magnesium, but data on its specific formulation and clinical effects is limited. Data not available for this product's proprietary blend or clinical trials.

How it works

Magnesium is an essential mineral involved in over 300 biochemical reactions in your body, including nerve function and stress response [NIH ODS]. The 350 mg serving in this powder provides a substantial portion of the RDA, which is 310–420 mg daily for adults depending on age and sex [NIH ODS].

Safety profile

Data not available for adverse event reports specific to this product. FDA data on magnesium supplements in general indicate that high doses can cause diarrhea and gastrointestinal discomfort, but specific report counts for this brand are not provided [FDA data].

Our recommendation

Start with a half dose to assess your tolerance, as the 350 mg serving is near the upper end of the daily recommended intake. Choose a form like magnesium glycinate or citrate for better absorption if you experience digestive upset [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
