Our Licensed Health Professionals offer a wealth of knowledge. This health tip is about "Vitamin D". "Vitamin D" occurs in two forms: D2 (produced by plants) and D3 (produced by the human skin). Both forms help maintain blood levels of calcium and phosphorus. Recent research suggests Vitamin D may protect against osteoporosis, hypertension, and some forms of cancer. Just 10-15 minutes of sun exposure during non-peak hours provides the daily recommended intake. If no sun, then fatty fish, egg yolks, and fortified milk also do the trick.
