# We Tested Magnesium for 30 Days — Here's Our Honest Report

Published March 10, 2026 • Longevity Futures Research Team

## The 30-Day Test

At Longevity Futures, we don't just review supplements from a spreadsheet. When a compound shows serious promise, we put it through a real-world test. Magnesium was next on the list.

### Week 1: Getting Started

We started with NOW Magnesium Glycinate (200mg per serving). The first few days? Honestly, nothing dramatic. No fireworks. That's actually a good sign — supplements that promise instant miracles are usually selling you caffeine or something your body will crash from later.

### Week 2: Subtle Shifts

By day 10, something started to change. Energy levels felt more consistent — not a spike, more like the afternoon slump just... didn't happen. Sleep quality seemed marginally better too, though that's harder to attribute directly to Magnesium.

### Week 3: The Noticeable Phase

This is when things got interesting. Recovery from workouts improved noticeably. Mental clarity in the mornings felt sharper. These align with what the research predicts — Magnesium supports Sleep quality and Stress reduction, and by week three, those cellular processes have had time to respond.

### Week 4: The Verdict

By day 30, the overall feeling was: genuinely better. Not transformed, not superhuman — just measurably, consistently better in energy, focus, and recovery. Exactly what you'd want from a longevity supplement.

## Would We Keep Taking It?

Yes. Magnesium earned a permanent spot in our daily stack. The effects are subtle but real, and the research backing it up gives us confidence this isn't placebo.

NOW Magnesium Glycinate specifically impressed us. At $16.99 with a score of 9.4/10 — Glycinate form is the most bioavailable and gentle on the stomach. Best choice for sleep and relaxation.

We also think pairing Magnesium with Curcumin could amplify the results. See our comparison guides for stack ideas.
