If you're dealing with digestive issues that haven't responded to lower-dose probiotics, this high-potency option delivers 100 billion CFU per capsule — sitting at the top of the clinically studied range (1–100 billion CFU). This potency level is where more intensive research protocols tend to operate.
The blend includes 8 well-researched strains spanning both **Lactobacillus** and **Bifidobacterium** genera, including L. acidophilus, L. rhamnosus, and B. lactis — all with individual clinical backing for gut health and immune modulation. The strain diversity here gives you broad coverage across your upper and lower digestive tract.
One thing to note: the label doesn't disclose individual CFU counts per strain, so you can't tell which strains dominate the blend. Higher total CFU also doesn't always mean better outcomes — some people experience bloating or gas when starting at this level, so you may want to build up gradually.
