KAL Citrus Bioflavonoid Complex Supplement, 1000mg, 100 Tablets

What the brand says

KAL was born in 1932 out of an act of love. Chester Weldon discovered a calcium and phosphorus powder that helped his beloved wifes leg cramps. Amazed by its effectiveness, he founded KAL in order to bring such life-changing solutions to others in need. We've been serving families ever since.
