Detailed Review

NOW Supplements Saccharomyces Boulardii is a targeted probiotic delivering 5 billion CFU of Saccharomyces boulardii, a beneficial yeast strain that supports a healthy balance of intestinal flora. This makes it an excellent choice for travelers, individuals prone to occasional diarrhea, and anyone looking to maintain digestive wellness during disruptions.

Real-world use shows consistent results in maintaining regularity and comfort.

Design is simple and functional. The product comes in a 60-count bottle of tan vegetable capsules that are easy to swallow and suitable for vegetarian and vegan diets. A notable storage consideration is that refrigeration is recommended immediately after delivery to preserve the 2-year shelf life, so proper handling is essential to get the most out of the supplement.

A potential drawback is the need for refrigeration, which may be inconvenient for those without easy access to cold storage or who prefer a shelf-stable probiotic. Additionally, this is a single-strain formula, so it does not offer the diversity of multiple bacterial strains that some users might expect from a broad-spectrum probiotic.

Overall, NOW Supplements Saccharomyces Boulardii is a high-quality, travel-ready probiotic with a focused purpose. Its potent CFU count, trusted manufacturing processes, and clean vegetarian capsules make it a reliable pick for digestive support. For those who do not mind the refrigeration requirement, it delivers excellent value and peace of mind.

Buying Guide

Strain and Scientific Backing

Florastor uses the patented strain Saccharomyces boulardii CNCM I-745, backed by over 65 years of research. This strain is known for its resilience against antibiotics and its ability to support digestive and immune health. In contrast, generic Saccharomyces boulardii supplements, like those from NOW, use a standard strain without the same level of clinical validation. If you prioritize proven research, Florastor offers a well-documented choice.

Potency and Dosage

Florastor provides 250 mg of the active yeast per capsule, which translates to a high viable count. NOW’s Saccharomyces boulardii delivers 5 billion CFU per capsule, a different measurement. The dosage recommendations also vary: Florastor suggests 2 capsules one to two times daily, while NOW recommends one capsule daily. Consider your desired CFU intake and convenience when choosing. For more on probiotic potency, see our best fiber capsules for men.

Storage and Shelf Life

One key difference is storage. Florastor is shelf-stable for up to three years without refrigeration, making it ideal for travel or daily use. NOW recommends refrigeration upon delivery to maintain potency through its two-year shelf life. If you prefer a no-fuss option, Florastor’s stability is a clear advantage.

Value and Bottle Sizes

Florastor offers multiple bottle sizes (20, 54, and 100 capsules) to suit different budgets and commitment levels. NOW provides a single 60-capsule bottle at a lower per-serving cost. If you’re trying Saccharomyces boulardii for the first time, a smaller Florastor bottle allows a trial without a large investment. For ongoing use, NOW may be more economical.
