Fibroplex MagActive for Kids is a great tasting, raspberry flavoured formula with no artificial colours, flavours or sweeteners, for easy magnesium supplementation in children. It is estimated that 1 in 3 children ages over two years are not meeting their recommended dietary intake of magnesium.[1]
It contains Magnesium bisglycinate, an easily absorbed form of magnesium. Fibroplex MagActive for Kids supports growing bodies, for health muscle function, energy levels and muscle relaxation. The activated forms of vitamin B6 and B12 are included to help maintain a healthy nervous system, mood and stress response.

Fibroplex MagActive Kids supports healthy muscle development, nervous system and energy production in children.
Magnesium is the fourth most abundant mineral in the human body and is required by over 300 enzymes to function adequately. It supports healthy growth and development in children, particularly bone mass, and may even ease growing pains during peak periods of growth. Signs of low magnesium include constipation, irritability, night time muscle cramps, difficulty sleeping and teeth grinding.
You may notice some interesting colour changes with this product. Rest assured, Fibroplex MagActive Kids does not contain any artificial colours or flavours. It is naturally coloured with anthocyanins, derived from black carrot extract. As the anthocyanins mix with water and malic acid (contained within Fibroplex MagActive Kids) they turn blue, before returning to a dark red hue.
At Metagenics, we use a specific form of high-quality magnesium known as magnesium bisglycinate. This form of magnesium is bound to the amino acid glycine, which improves its bioavailability and absorption. It is also gentler on the stomach and less likely to cause gastrointestinal upsets. However, some people may still experience loose stools or diarrhea when taking high doses of magnesium. If this happens, try reducing your dose by half, e.g. Instead of taking two serves per day, cut down to one serve. You can then gradually increase it over a week or two to find the optimal dose for you.

"My son takes this daily and he feels good."
— Uri (5/5)
"I have been trying for years to get my children on supplements. But they just outright refuse to take any. This is the only drink I can get them to have. They love how it’s blue at the start then mixes to a pinky red colour! I give this to them every night before bed, I notice they actually stay asleep in their beds but also wake up happy and fresh. Before the magnesium they would wake up tired, cranky and irritable"

"My kid absolutely hates the taste but I do feel like it might be helping his energy levels."
— Laura (3/5)
"My kids didn't love the flavour of this one so I took it with amazing results for sleep and muscle twitches. I would love to see a more neutral flavoured product that might be easier to disguise for fussy eaters if possible. Thankyou so much."
— Belinda B. (3/5)
