MultiRight is stomach and bladder friendly.  It will not cause any stomach upset or bladder irritation because it does not add any additional acids into your system. 

MultiRight is the only pH neutral, low acid multivitamin which means that it's more bladder friendly than ever! MultiRight is a proprietary formula that delivers everything you need in a multivitamin and mineral complex without the high acid levels that can contribute to bladder or stomach irritation in sensitive people.

Why is a low-acid formula helpful? If you have a sensitive bladder and/or stomach, you know just how difficult it is to tolerate coffee, orange juice and, yes, even a simple multivitamin. Patients with interstitial cystitis, prostatitis or stomach ulcers, for example, find it very difficult to tolerate conventional vitamin supplements often due to their high acid levels.

Why are multivitamins often too acidic? Most of the brand name vitamins you'll find on supermarket shelves source their ingredients based on cost and availability. The cheapest form of Vitamin C, for example, is ascorbic acid derived from citrus fruits grown in many parts of the world.
