Is Protein Optimizer right for me?

Thorne Protein Optimizer helps maximize protein intake and reduce negative side effects associated with high-protein diets, like occasional gas or bloating. It enhances protein digestion while maintaining a healthy microbial balance in the gut.

Does Protein Optimizer contain protein?

No. Protein Optimizer does not contain any protein. It is a probiotic and enzymatic formula designed to improve the digestion and absorption of protein from your favorite Thorne protein powder or other protein-rich foods.

What testing does Thorne complete for Protein Optimizer?

We test this supplement for identity, purity, and potency to meet our strict quality standards. NSF Certified for Sport® products have been third-party tested to ensure the absence of nearly 300 substances banned by major athletic organizations. 

What is the difference between Protein Optimizer and other probiotic supplements?

While probiotic supplements may address any number of health concerns, Protein Optimizer is a targeted formula that specifically addresses both plant and animal protein digestion and absorption.*

What is the difference between probiotics and digestive enzymes?

Probiotics are living microorganisms that affect gut bacterial populations and microbiome health, while digestive enzymes are proteins that directly break down food into absorbable nutrients.
