Why people keep reordering it
- Highly absorbable forms
- Chelated forms your body takes up, instead of oxide that mostly passes through.
- Calm and recovery
- Supports muscle relaxation, sleep quality and everyday stress resilience.
- Gentle on digestion
- Formulated to skip the laxative effect of cheaper magnesium.
Best suited to: someone whose diet already covers most calcium needs, people wanting a higher magnesium dose in one tablet, someone managing occasional muscle cramping or tightness.
What the research supports
One tablet gives 400 mg of magnesium and 200 mg of calcium, plus a small amount of vitamin D. The bottle of 90 lasts three months.
Studies use 300 to 400 mg of magnesium a day.
- Muscle cramps (evidence: moderate, from rct, systematic review)
- Muscles need magnesium to relax after they contract, and low intake is linked to more cramping and twitches, especially when intake falls short.
- Bone maintenance (evidence: moderate, from rct, systematic review)
- Calcium is the mineral your bones are built from, and vitamin D helps your body absorb it into bone rather than just circulating. The amounts here are modest against a full daily target.

Is it right for you
Worth it if
- someone whose diet already covers most calcium needs
- the 2:1 magnesium to calcium ratio is built to top up magnesium without overshooting calcium from food and supplements combined.
- people wanting a higher magnesium dose in one tablet
- 400 mg of magnesium per tablet is a substantial single dose, useful for those who don't want to take multiple capsules.
- someone managing occasional muscle cramping or tightness
- magnesium at this dose is commonly used to support normal muscle contraction and relaxation.
Look elsewhere if
- someone relying on this as their main vitamin D source
- look for a standalone vitamin D3 supplement in the 1000 to 2000 IU range, since 100 IU here is a fraction of typical maintenance doses.
- someone who needs a full calcium supplement for bone support
- a product with 500 to 600 mg of calcium per serving will do more toward daily calcium targets, since 200 mg here is a supporting dose.
- people sensitive to magnesium oxide's laxative effect
- a fully chelated form like magnesium glycinate or bisglycinate is gentler on digestion at comparable doses.
What to expect
Muscle relaxation and reduced tightness from the magnesium can show up within days to a couple of weeks of consistent use. The calcium and vitamin D contributions here are too small to notice directly, they work in the background alongside diet over months, not something you'll feel.
How it compares
- Compared with a plain calcium and vitamin D tablet
- this product leads with a much larger magnesium dose, which most calcium-only products don't include at all. The tradeoff: you get less vitamin D and less calcium per tablet than a product built around those two alone.
- Compared with magnesium bisglycinate or citrate on its own
- this combines magnesium with calcium and a small amount of vitamin D in one tablet, useful if you want fewer bottles. The tradeoff: part of the magnesium is oxide, which the body absorbs less efficiently than glycinate or citrate.
