Nutravita Magnesium Supplements ...
Pros
- ✓Multiple reviewers report genuine improvements in night-time muscle cramps and sleep depth
- ✓400mg elemental magnesium is a full therapeutic dose — not token amounts
- ✓Includes bisglycinate and citrate, two of the best-absorbed forms available
- ✓Which? Best Buy 2025 rating and UK GMP/BRC manufacturing standards
Cons
- ✗Magnesium oxide is the lowest-bioavailability form (~4%) and pads the blend without proportional benefit
- ✗Per-form ratios are not disclosed — you cannot tell how much bisglycinate versus oxide you're actually getting
- ✗Not independently third-party tested; GMP/BRC covers manufacturing process, not label accuracy
- ✗One reviewer explicitly notes this is a suboptimal choice if sleep is the primary goal — glycinate or L-threonate alone may work better
Best For

What does the data say about Nutravita Magnesium Su... vs Magnesium Citrate 120 Tablets?
Four hundred milligrams of elemental magnesium per two-capsule serving sounds generous, but the blend quality is uneven: bisglycinate and citrate are genuinely good forms, malate earns its place for energy metabolism, yet oxide — with roughly 4% bioavailability — is bulk filler that inflates the headline number.

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.
