Increasing cholesterol levels:

Concern has been raised about the stearic acid in Magnesium stearate (Magnesium octadecanoate) raising cholesterol levels, as stearic acid is a saturated fat. 

This should not be a concern because even normal dietary intake of stearic acid has been shown to have no significant effect on total cholesterol, low-density lipoprotein (LDL) or high-density lipoprotein (HDL) cholesterol levels. 

In addition, the amount of stearic acid from Magnesium stearate (Magnesium octadecanoate) in supplements is very small. 

According to USDA nutrition surveys, the average American adult consumes between 5,900 to 8,800 milligrams of stearic acid each day, typically from food sources like beef, poultry, cocoa butter, milk and cheese.

At least one case of allergic reaction to Magnesium stearate (Magnesium octadecanoate), which resulted in skin hives, has been reported. 

However, this type of reaction seems to be quite rare.
