Protein Optimizer

Consuming enough protein is essential for muscle recovery, performance, and overall health – but adding protein to your meals is only part of the equation. To get the full benefit, your body needs to efficiently digest the protein you consume, absorb its amino acids, and utilize those nutrients where they’re needed most.

Protein Optimizer is designed to support this process through the gut-muscle axis – the connection between gastrointestinal (GI) health, nutrient absorption, and muscle function – with a targeted formula that combines Mycohsa™, a probiotic blend with digestive enzyme support, and Bacillus coagulans SNZ 1969^®, a clinically studied probiotic strain.

Together, these ingredients promote healthy digestion, support microbiome balance, and enhance the absorption of nutrients that help build lean muscle mass.*

A deeper look at the patented ingredients in Thorne Protein Optimizer

Mycohsa™

Designed to promote a balanced GI environment and support protein utilization, Mycohsa™ is a blend of three probiotic bacterial strains (Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, and Bifidobacterium breve), a yeast strain (Saccharomyces boulardii), and the digestive enzyme amylase. Each strain was selected for its ability to survive in the acidic stomach environment when taken within 30 minutes of a meal, helping support the gut’s barrier function, beneficial microbial balance, and the absorption of protein from plant sources.*

• Supports gut wall integrity, improving intestinal permeability*
• Enhances proteolytic enzyme levels to support protein digestion*
• Supports a healthy balance of Candida and other gut microbes*
• Supports immune health by promoting microbial balance in the gut*
• Enhances the absorption of protein from plant sources*

Bacillus coagulans SNZ 1969^® 

Bacillus coagulans SNZ 1969^® is a clinically studied, spore-forming probiotic strain that supports digestive health, microbiome balance, and nutrient absorption.*

Because it is designed to survive the acidic environment of the stomach, Bacillus coagulans SNZ 1969^® can reach the intestines, where it retains its potency to help support digestive comfort, bowel regularity, and the absorption of whey protein.*

• Enhances the absorption of milk-derived proteins, such as whey*
• Promotes a healthy balance of good bacteria in the gut*
• Supports digestive comfort, providing relief from occasional gas, bloating, cramping, constipation, and diarrhea*
• Eases occasional upper digestive discomfort*
• Supports bowel transit time in individuals with occasional constipation*
