Nutricost Probiotic Complex Specs
Our Experience With Nutricost Probiotic Complex
Pete, our certified nutrition coach, tested Nutricost’s Probiotic Complex. The capsules cost around 37 cents per serving, and each bottle includes 60 days’ worth of probiotics. In addition to having a fantastic value, the probiotics include ten different strains of gut-supporting bacteria.
Probiotics are “good” bacteria and yeasts that, when eaten in the right amounts, help keep your gut healthy. They’re found naturally in certain fermented foods—like yogurt, kimchi, and sauerkraut—and can also be taken as supplements. While probiotics aren’t gender-specific, some do include extra ingredients intended to support men and women’s unique bodies.

These beneficial microbes help restore balance in your digestive system and get rid of harmful bacteria, all while helping support normal body functions. By keeping your gut in check, probiotics may ease digestive discomfort, help your immune system, and support your overall well-being, especially when things like stress, poor diet, or antibiotics disrupt your gut’s natural balance.

- Instructions (5 out of 5): The instructions are easy to read and understand. “As a dietary supplement, take one capsule daily with 8-12 oz. of water or as directed by your healthcare professional,” he said
