Order ImproBiome — Pricing & Packages
Current ImproBiome Prebiotics Formula packages, per-bottle pricing and the 365-day guarantee. Verify live pricing on the official checkout before you buy.
Below are the ImproBiome packages offered by PureHealth Research. Like most supplement brands, they price by volume — the more bottles in your order, the lower the per-bottle cost, plus free U.S. shipping on multi-bottle packages. Because prebiotics work best with consistent daily use over several weeks, the multi-bottle options tend to be the most popular.

Which package should you choose?
- 1 bottle (Starter): a 30-day trial run. Good if you just want to test how your gut responds — the 365-day guarantee still applies.
- 3 bottles (Popular): a 90-day supply. This is roughly the window most people need to fairly judge a prebiotic, with free shipping.
- 6 bottles (Doctor's Choice / Best Value): a 180-day supply at the lowest per-bottle price, with free U.S. shipping. Best for anyone committing to a consistent routine.

Every package is backed by the PureHealth Research 365-day money-back guarantee. If you're not satisfied, contact PureHealth Research within 365 days for a refund. That long window is ideal for a prebiotic, which rewards patience.
