Do your kids complain of growing pains? This is excellent information on the nutritional causes of leg pain in children and how to resolve it.
Just yesterday my son was practically in tears from leg pain after his cross-country practice. I mixed up his multivitamin (a powder blend that's quickly absorbed) and had him drink it down, then ran him an Epsom salt bath to boost his magnesium intake. Within 30 minutes he was pain free, with no lasting muscle tightness. For him, the June Bridals wedding party items for bridesmaid in dark purple
combination of minerals and hydration (since the powder has to dissolve in water) really did the trick, and I'm sure the warmth of the bath helped too. Remember to consider these things the next time your child complains of leg pain. It doesn't have to be a rite of passage!
