However, if you have this condition and are taking medications, you may wish to speak with your medical provider about lactose-free options, as it may not always be clear whether a drug harbors lactose.

Finally, some individuals may be allergic to the proteins in milk but can safely consume lactose and its derivatives. In this case, it’s still important to consult a healthcare professional to ensure that products with lactose monohydrate are safe for you.

If you’re concerned about lactose monohydrate in food, be sure to carefully read food labels, especially on packaged desserts and ice creams that may use it as a sweetener.

While lactose monohydrate is considered safe for most people, consuming it in excess may cause gas, bloating, and other issues for those with lactose intolerance.

The bottom line

Lactose monohydrate is a crystallized form of milk sugar.

It’s commonly used as a filler for medications and added to packaged foods, baked goods, and infant formulas as a sweetener or stabilizer.

This additive is widely considered safe and may not cause symptoms in those who are otherwise lactose intolerant.

However, those with severe lactose intolerance may wish to avoid products with this additive to be safe.
