Phyto Cal-Mag Plus is a calcium/magnesium blend designed to promote healthy relaxation. Phyto Cal-Mag Plus has a 2:1 calcium/magnesium ratio that allows the body to absorb these nutrients easier. Even the most compromised digestive systems can absorb the nutrients with this ratio. Magnesium is vital for normal sleep patterns and also supports normal nervous system function. Phyto Cal-Mag Plus also provides the body with vitamin D3, which not only facilitates intestinal absorption of calcium, but also helps with bone growth and immune function. Phyto Cal-Mag Plus also consists of a concentrated valerian root extract powder. Research shows that valerian root helps to support deep, restful sleep patterns and has been used by herbalists for centuries to promote relaxation
