Viva Vitamins Super Magnesium 375 MG
Brand: Viva Vitamins · Form: TABLET [E0155]
Our assessment
Our assessment: The evidence shows that magnesium is essential for over 300 enzyme reactions in your body, and ensuring adequate intake is critical for heart rhythm, muscle function, and bone health [NIH ODS]. For a 375 mg product, you should know that the Recommended Dietary Allowance (RDA) for magnesium is 310–420 mg daily for adults, depending on age and sex, so this supplement provides a substantial portion of that requirement [NIH ODS].
How it works
Think of magnesium as a gatekeeper — it helps regulate nerve signals by blocking calcium from entering cells, which allows muscles to relax after contraction. This mechanism supports normal blood pressure and steady heartbeats [NIH ODS]. It also assists in converting food into energy and helps your body build proteins and strong bones [NIH ODS].
Safety profile
Data on adverse events for this specific product are not available. However, high supplemental magnesium intake (above 350 mg daily from non-food sources) can cause diarrhea, nausea, and abdominal cramping [NIH ODS]. If you have kidney disease, consult your doctor before use [NIH ODS].
Our recommendation
Start by assessing your total magnesium intake from food (nuts, seeds, leafy greens) and other supplements. If you are deficient or at risk, a 375 mg dose may be appropriate, but consider splitting the dose to reduce digestive discomfort. Choose magnesium citrate or glycinate for better absorption [NIH ODS].
