I noticed Citrucel Soft Chews with SmartFiber don’t have vitamin D. Don’t you need vitamin D to absorb the calcium?
Yes, vitamin D is critical to the absorption of calcium. There are many ways of getting vitamin D, including fish, dairy products, fortified cereals and even sunlight. Talk to your doctor if you think you’re not getting enough vitamin D from your diet, or if you have one or more factors for vitamin D deficiency, including being over the age of 70, being homebound or having a gastrointestinal disease that causes poor vitamin D absorption.
