Complete Probiotics is a daily probiotic supplement that helps support a balanced gut and immune health, thanks to Lactobacillus acidophilus DDS-1, from Dr Mercola. The formula combines a broad probiotic blend with prebiotic fructooligosaccharides to nourish gut bacteria and improve resilience against everyday digestive stress. This quality focus comes from strict standards, and Dr Mercola is known for transparency in the probiotic field, making this a reliable daily addition.

Benefits & Features:

• Supports daily digestive comfort and gut balance.
• Delivers a robust blend of strains to help immune health.
• Delayed release capsules protect the contents from stomach acid, helping more live bacteria reach the gut where they can support balance and nutrient absorption effectively.
• NSF contents certified and cGMP-compliant manufacturing underpin the quality you can trust for probiotics.
• Contains Fructooligosaccharides (FOS) to support probiotics for gut health and boost activity in the gut.

Dr Mercola Complete Probiotics blends ten strains with prebiotic FOS in a delayed release capsule to help more live bacteria reach the gut. NSF contents certified and produced under cGMP, the formula is tested for potency and identity to ensure you receive what's stated. The brand's heritage of quality and transparency shines through with a shelf-stable, no refrigeration required design. It fits easily into daily routines and speaks to probiotics for gut health and the broader probiotic conversation, including probiotics for vaginal health.
