Our Verdict: Solgar Calcium Magnesium + Zinc or Solgar Magnesium Citrate?
Solgar's Calcium Magnesium plus Zinc wins at £9.22 versus £17.94, delivering broader bone, muscle, and sleep support across three minerals with a score of 74/100. The Magnesium Citrate is worth the premium only if absorption is your priority — its higher ingredient quality score (84 vs 66) reflects the superior citrate form. Those with digestive sensitivity or a specific magnesium deficiency should opt for the citrate; everyone else gets better value from the combo tablet.

Solgar Calcium Magnesium + Zinc scores 74.0/100 vs Solgar Magnesium Citrate at 72.0/100. Solgar Calcium Magnesium + Zinc wins on effectiveness, value for money, side effects. Solgar Magnesium Citrate is stronger on ingredient quality.
Solgar Calcium Magnesium + Zinc vs Solgar Magnesium Citrate: What Does the Data Say?
The biggest difference between these two Solgar products comes down to the form of magnesium used. The Calcium Magnesium plus Zinc contains magnesium oxide, which is the least bioavailable form available — your body absorbs relatively little of it. The Magnesium Citrate 120 Tablets uses magnesium citrate, which absorbs considerably better. That gap shows clearly in the ingredient quality scores: 84/100 for the citrate version versus 66/100 for the blend. The blend does bring something extra to the table, though — calcium and zinc alongside magnesium, making it a three-in-one for bone and dental support rather than a single-mineral supplement.
If you're primarily after sleep support or muscle cramp relief and want the best absorption for your money, the Magnesium Citrate is the more effective choice on a per-ingredient basis. But at £17.94 for 120 tablets versus £9.22 for 250, the Calcium Magnesium plus Zinc wins decisively on value (73/100 versus 62/100) and edges ahead overall at 74/100 to 72/100. Anyone wanting combined bone support alongside magnesium will find the blend more practical — one product instead of two.
Both tablets are large. This isn't a minor footnote — reviewers of both products specifically flag swallowing difficulty, with the citrate version drawing more serious comments about choking risk. If you struggle with large tablets, neither will be comfortable, but the citrate product appears to be the worse offender. The Calcium Magnesium plus Zinc comes in a glass jar, which reviewers consistently appreciate; packaging details for the citrate version aren't highlighted.

What the Data Says
Why is magnesium oxide less effective than glycinate?
Oxide scores 21 points lower than glycinate in our testing — and it's not close on ingredient quality either. Across 17 magnesium products in our database, glycinate averages 74.3/100 overall. Oxide sits at 53/100. That's a gap you can feel.
The ingredient quality difference is even starker: 83.3 for glycinate vs 37.0 for oxide. A 46.3-point gap. The best glycinate in our database, Solgar Magnesium Glycinate 400mg, scores 80/100 overall with 88/100 on ingredient quality. The oxide product (Nature Made) manages just 52 on effectiveness and 37 on ingredient quality.
The reason is bioavailability. Magnesium oxide has roughly 4% absorption — most of it passes straight through your gut unused. Glycinate is chelated (bound to the amino acid glycine), which your intestines absorb much more efficiently. You also get fewer digestive side effects, since unabsorbed magnesium in the gut is what causes the laxative effect oxide is known for.
Oxide is cheap, which is why it's still everywhere. But cheap per pill means nothing if your body can't use it. Glycinate or citrate (avg 74.5/100) are both better choices.
Which form of magnesium is best for sleep, anxiety, or muscle cramps?
Glycinate for sleep and anxiety. Citrate for cramps. L-threonate for brain function. Each form has a different strength, and our scores back this up.
Sleep and anxiety → Glycinate. Averaging 74.3/100 across our database, with the best (Solgar Glycinate 400mg) hitting 80/100. Glycine, the amino acid it's bound to, acts as an inhibitory neurotransmitter — it calms your nervous system on its own. That's a two-for-one benefit you don't get from other forms. Thorne Bisglycinate (74/100) is another solid option at a lower dose.
Muscle cramps → Citrate. Averaging 74.5/100 overall with 85.0 on ingredient quality. Citrate absorbs well and is gentler on your wallet than glycinate. Solgar Citrate leads the pack at 77/100. If cramps are your main issue, this is the practical choice.
Brain function → L-Threonate. Life Extension Neuro-Mag scores 73/100. This is the only form shown to meaningfully raise magnesium levels in the brain by crossing the blood-brain barrier. It's pricier, but nothing else does what it does.
All-round absorption → Doctor's Best High Absorption tops our entire magnesium database at 82/100 overall (83 effectiveness, 88 ingredient quality) using chelated magnesium.
The one form to skip? Oxide at 53/100. Its 4% absorption rate makes it a poor choice no matter what you're taking it for.
