In the UK, popular options include magnesium glycinate, which has high absorption and is gentle on the stomach, and magnesium citrate, which many people use for general wellbeing. If you want support for energy, sleep, and muscle function, a combined formula with citrate, glycinate, malate, or taurate may be ideal. The key is to choose a trusted brand with good-quality ingredients that are free from unnecessary fillers or additives.
