The five products included in this comparison.

Magnesium products can look remarkably similar from the front. Examine the formula, however, and meaningful differences begin to appear.

Some products centre on one principal form of magnesium. Others combine glycinate, citrate and malate. Serving format and price also affect how easily a supplement fits into a daily routine.

The biggest number on the packet does not necessarily identify the most complete formula.

Magnesium contributes to normal psychological function, normal functioning of the nervous system, normal muscle function and the reduction of tiredness and fatigue.

The results

Five formulas, ranked

Each product has legitimate strengths. The deciding factor was which delivered the best complete balance.

#5
Vitabiotics Ultra Magnesium
Straightforward basic option

Vitabiotics Ultra Magnesium

A widely available tablet providing a stated 375mg daily serving. Its listed magnesium source is magnesium hydroxide, making it simpler than the multi-form leaders.

  • Established UK brand
  • 375mg stated serving
  • Widely available
Limitation: primarily relies on one magnesium form.
#4
Holland and Barrett Magnesium Bisglycinate
Focused capsule formula

H&B Magnesium Bisglycinate

A convenient option for customers specifically looking for bisglycinate. It is focused and easy to understand, but it does not combine citrate and malate.

  • Bisglycinate-focused
  • Capsule format
  • Major UK retailer
Limitation: narrower than a genuine three-form blend.
#3
Solgar Magnesium Citrate
Premium citrate option

Solgar Magnesium Citrate

A recognised citrate formula from a long-established supplement brand. It provides a stated 400mg daily serving across two tablets.

  • 400mg stated serving
  • Established brand
  • Clear citrate focus
Limitation: does not combine glycinate and malate.
#2
BetterYou Magnesium Max
Strongest alternative

BetterYou Magnesium Max 3-in-1

A genuine three-form powder combining magnesium glycinate, citrate and malate. It offers an excellent formula, although the powder must be measured and mixed with water.

  • Three magnesium forms
  • 375mg elemental magnesium
  • Established magnesium brand
Limitation: the powder format will not suit customers wanting a quick capsule serving.
