The best probiotic i've ever taken

The ingredients are incredible, containing literally every beneficial bacteria that can live in our gut. It has l-Reuteri, Saccharomyces, and more. It's the most comprehensive formula on the market. Huge servings—100 billion per capsule—plus prebiotics and postbiotics. It's simply the best comprehensive probiotic on the market.

Good quality

Mega Probiotic 120 capsules. The ingredients are good. I take one capsule every morning after waking up. It has good results, helping with bowel movements and constipation. It also aids digestion. The capsules are easy to swallow, suitable for me at age 58. The packaging is good. I like this brand.

Powerhouse probiotic supplement - best quality that iHerb offers IMO. Straightforward ingredients, simple package, small capsule size - marked benefit to gut, digestion, and microbiome. Highly recommend.

Good combo

Verified purchase

I bought this supplement to help my digestion. I like that the ingredients include probiotics, prebiotics, digestive enzymes for gut balance. I like that it contains 200 billion CFU and many strains. I think the quality is pretty good. The size of the vegetarian capsules is average and easy to take.
