Best For
Life Extension Neuro-Mag Magnesi...
Pros
- ✓Magtein (patented Mg L-threonate) is the most researched form for crossing the blood-brain barrier and supporting cognitive function
- ✓Reviewers consistently report improved memory, concentration, and reduced brain fog after several weeks of use
- ✓Sleep quality improvements frequently mentioned — easier to fall asleep, fewer nighttime awakenings
- ✓Clean formula: vegan capsules, no dairy, gluten, soy, or artificial flavours; third-party tested
Cons
- ✗Premium pricing with only 30 servings per bottle makes ongoing use costly compared to standard magnesium forms
- ✗High capsule load (3 per serving) due to low elemental magnesium yield of the L-threonate form
- ✗Some users report vivid dreams or mild sleep disruption, especially if taken close to bedtime
- ✗Effects are gradual — requires 2–4 weeks of consistent use before benefits are noticeable

What does the data say about BetterYou Magnesium Body Spray vs Life Extension Neuro-M...?
These two products share a score of 73/100 but couldn't be more different in purpose. BetterYou's Body Spray delivers 150mg of magnesium chloride per five sprays transdermally — absorbed through the skin, bypassing the digestive system entirely. Life Extension's Neuro-Mag uses Magtein, a patented magnesium L-threonate form specifically developed to cross the blood-brain barrier, dosed at 144mg elemental magnesium per serving across three capsules. The spray costs £8.33; the capsules cost £37.90 for 30 servings, making ongoing use considerably more expensive.
If you struggle with the GI side effects common to oral magnesium — loose stools or cramping — or want something to rub into sore muscles after exercise, the BetterYou spray is a genuinely useful option. Its formula is exceptionally clean: just Zechstein-sourced magnesium chloride and purified water. The Neuro-Mag is aimed at a completely different person — someone specifically chasing cognitive benefits like memory support or reduced brain fog, particularly over-50s or those under sustained mental demand.
Worth noting: the spray can sting on sensitive or freshly shaved skin, so start with a small patch. The Neuro-Mag's three-capsule serving size is manageable for most people, but the value score of 52/100 reflects the premium you're paying for a relatively modest elemental magnesium yield.
BetterYou Magnesium Body Spray delivers magnesium chloride sourced from the Zechstein seabed transdermally, bypassing the digestive tract — an approach favoured by those with GI sensitivity to oral magnesium.

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.
