Estrogen, Serotonin and Pain

Pain is a subjective perception influenced by numerous factors. Pain sensitivity can be vastly different from one person to the next.

Researchers have found that there are actual differences in how men and women experience severity of pain, because sex hormones are involved in pain transmission and sensitivity.

The connection between thyroid function and weight gain

There are many factors that affect weight management, and for those who struggle with this it may be worth investigating other causes of this “stubborn metabolism.” One such cause is the functioning of the thyroid gland and its respective hormones. Thyroid hormones play crucial roles in how the body uses energy and regulates appetite. Additionally, fat cells, also called adipose tissue, contains their own messengers and hormones that affect energy stores and usage. The interaction between these cells, their messengers and

When Vitamins and Supplements are Worth the Investment

We’ve all seen media claims that supplements can be a “waste of money” while other reports illustrate the dangers of “natural products”. So how valid are these claims? It’s all in the fine print. A catchy fear-inducing headline is sure to make waves, but it’s time to break down the science – and the actual text – of this information. When are supplements actually not worth it, and when can they actually make a difference in your health? What outcomes are we looking for?
