Slow-Mag Fizzy 20 Effervescent Tablets

This is the 20-tablet pack of Slow-Mag Fizzy, a mid-size option that covers three weeks of daily use. Magnesium sits at the centre of energy metabolism, nerve conduction and muscle relaxation, and it helps the body regulate calcium, potassium and vitamin D. Vitamin C supports the function of white blood cells, protects cells from oxidative stress and is required to build collagen in skin, gums and blood vessels. It also improves the absorption of iron from food.

Cramps, tiredness and tension are often the body's way of asking for magnesium. If you train hard, sweat a lot, take a water tablet or a stomach-acid reducer, or simply wake up with calf cramps, your magnesium stores are probably running behind what your muscles and nerves use each day.
