Muscle Flex

A breather for your Sporty Spice muscles.

Muscle tension, twitching eyelids, (nightly) cramps in your calves… All things that can be quite annoying during a yoga session or fast workout. Muscle Flex will keep you in excellent shape, every day.

Healthy muscles

Magnesium and vitamin B6

Your body needs magnesium even more during intense exercise, and a shortage will affect your muscle contraction mechanisms. Too little magnesium in your system causes the muscles to contract and reduces your muscle function. It can also wake you up with painful cramps in your calves in the middle of the night. Muscle Flex resolves this problem. The vitamin B6 reduces your fatigue and keeps your mental health in excellent shape.

One tablet a day, preferably in the morning, will keep you in great shape without too much effort. Suitable for adults and children over twelve years of age.
