TruBifido Master Supplements 30 Capsules - Powerful Probiotic for Colon Health & Energy - Immune Booster, Supports Regularity - Gluten Free - 30 Servings

Master Supplements appears to be a reputable company with a range of probiotics that have helped many customers with their digestive issues. However, a few customers have reported reformulation issues; one customer experienced severe abdominal pain after discovering changed strains in their recently purchased bottle of TruBifido, but was happy with the company's response in replacing it. Another customer reported nausea and stomach aches after using a newly purchased bottle of FLORA and BIFIDO, and could not return or get a refund for the product. However, most of the customers' experiences with Master Supplements' probiotics have been positive, with many reporting improved digestion and bowel movements, help with allergies and inflammation, and even positive effects on their dreams and overall well-being.
