Among this week’s reports, the ABC News write-up by Nick Wasson did better than most in getting a range of medical perspectives and exploring the full spectrum of risks. But the strongest account probably came from Denise Mann, writing for HealthDay, which is picked up by WebMD and consumer outlets. She wrote:

Dr. Susan Zweig, an endocrinologist and clinical assistant professor of medicine at NYU Langone Medical Center in New York City, expressed more concern.

“It is hard to get toxic levels vitamin D, but it is certainly possible,” Zweig said. “Vitamin D is stored in fat so it can build up, unlike other vitamins that we pass when we urinate.” People with liver or kidney conditions may be at higher risk for vitamin D toxicity, she said.

As cliché as it sounds when you hear it, there’s a reason pharmaceutical commercials end with “Ask your doctor if it’s right for you.”
