Haines wasn't sleeping well, was stressed and was lacking energy so he went to see Dr. Harlan Bieley.

Bieley is an Anti-Aging & Functional Medicine specialist.

After extensive testing, Bieley put Haines on a vitamin regimen and within a few weeks of testing he felt much better.

"I know vitamin D was a vitamin that he recommended," said Haines. "I sleep very well, I sleep through the night and my energy level is excellent."

Haines is just one of the many cases, Bieley sees on a regular basis.

"We test, we treat, we retest. That is the safest way to do these things," said Bieley.

"This work is not just a pill for an ill," said Bieley. "You have to make lifestyle changes, you have to follow through with these nutrient."
