Can Supplements be a tax write-off?
Nutritional Supplements
You cannot include in medical expenses the cost of nutritional supplements, vitamins, herbal supplements, “natural medicines," etc. unless they are recommended by a medical practitioner as treatment for a specific medical condition diagnosed by a physician. Otherwise, these items are taken to maintain your ordinary good health, and are not for medical care.
The above being said, Weight Loss programs and their associated costs can be deducted if they are prescribed by a physician for treatment of an actual medical condition of which obesity is one of those conditions. However, once the obesity is resolved, as WLS does, the diagnosis is no longer there, so it is a very grey area as to whether continued use can be deducted or not or whether the supplements at that point are just being taken to maintain "ordinary good health"
As far as I know, it has not been tested yet in court. I advise my clients not to try the deduction because it's just not worth the aggrevation to be the test case for the IRS.
Have a great day :)
