Why We Chose It

Vitamin Bounty’s Pro 50 Probiotic took second place with a potent 50 Billion CFUs and 13 unique strains. The product is popular in the market, and it uses a delayed-release capsule. A notable concern is that it does not list sub-strains on its label or website. The lack of sub-strains leads us to believe that Vitamin Bounty may be using generic lower quality probiotic strains in their formula.

Other concerns are that the formula includes the synthetic additive Magnesium Stearate and has a limited 30-day return policy. Some users reported initial side effects of bloating and gas, which subsided after the first few weeks. Some of these issues may be the reason the product does not appear to be endorsed by a doctor specializing in digestive health.
