Key Ingredients Protease Enzyme Blend — 250 mg (87,500 HUT): A specialized combination of protein-digesting enzymes derived from Bacillus subtilis and Ananas comosus (pineapple). Proteases help hydrolyze dietary proteins into smaller peptide fragments and amino acids. The formula provides 87,500 HUT of labeled protease activity per capsule. Bacillus subtilis Protease: An enzyme source derived from Bacillus subtilis, used to help break peptide bonds within dietary proteins. This ingredient contributes to the formula's protein-digesting enzyme activity. Ananas comosus (Pineapple) Protease: A pineapple-derived proteolytic enzyme source associated with bromelain-type activity. These enzymes help break down proteins into smaller fragments during digestion. Proprietary Probiotic Blend — 21 mg (1 Billion CFU): Combines four probiotic microorganisms selected to support normal digestive function and gut microbial balance, alongside amylase. The Supplement Facts panel identifies 1 billion CFU for the probiotic blend but does not disclose individual CFU amounts for each microorganism. Saccharomyces boulardii (16mxg): A probiotic yeast commonly used in digestive wellness formulations. Saccharomyces boulardii has been studied for its interactions with intestinal microbial balance and normal digestive function.* Lactobacillus acidophilus (16axg): A Lactobacillus species commonly found in probiotic supplements. It produces lactic acid and is used to support a healthy intestinal microbial environment.* Lacticaseibacillus rhamnosus (18fx): A probiotic bacterial species used in digestive health formulations. Members of this species have been investigated for their interactions with intestinal microbial balance and gastrointestinal function.* Bifidobacterium breve (19bx): A beneficial bacterial species found in the human intestinal microbiome. Bifidobacterium breve is commonly included in probiotic formulas designed to support digestive wellness and microbial diversity.* Amylase: A digestive enzyme involved in breaking down starches and other digestible carbohydrates into smaller carbohydrate molecules. It complements the formula's protease enzymes by providing additional digestive enzyme activity.* How It Works Protein digestion begins in the stomach and continues in the small intestine, where digestive enzymes break intact dietary proteins into smaller peptides and individual amino acids that can be absorbed and utilized by the body. Jarrow Formulas Gut & Protein Optimizer combines a 250 mg protease enzyme blend providing 87,500 HUT of enzyme activity with a 1 billion CFU probiotic blend to complement these normal digestive processes. Proteases derived from Bacillus subtilis and Ananas comosus help hydrolyze peptide bonds within dietary proteins, while amylase contributes additional carbohydrate-digesting enzyme activity. The probiotic blend supplies Saccharomyces boulardii, Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, and Bifidobacterium breve to support the intestinal microbial environment. The gut microbiome interacts with dietary nutrients and influences numerous aspects of normal digestive physiology. In published human research involving probiotic supplementation with pea-derived protein, researchers observed higher circulating essential amino acid levels approximately two hours after protein consumption compared with protein alone. This finding supports the potential for selected probiotics to influence protein digestion and amino acid availability, although it does not establish that every protein source or every individual will experience the same response. By combining protein-digesting enzymes with complementary probiotic microorganisms, Gut & Protein Optimizer is designed to support protein utilization, digestive comfort, and gut wellness as part of a balanced, protein-containing diet.* What Makes It Different Enzymes + Probiotics: Combines two complementary approaches to digestive wellness rather than relying exclusively on enzymes or probiotic microorganisms. 87,500 HUT Protease Activity: Clearly discloses protein-digesting enzyme activity in addition to the 250 mg protease blend weight.

It is a digestive enzyme and probiotic supplement designed to support the breakdown of dietary protein, amino acid availability, digestive comfort, and gut wellness. Each capsule combines 250 mg of protease enzymes with a 1 billion CFU proprietary probiotic blend.* How does Gut & Protein Optimizer support protein digestion? Its protease enzymes help break down dietary proteins into smaller peptides and amino acids during digestion. The accompanying probiotic blend provides additional support for normal digestive function and gut microbial balance.* Does Gut & Protein Optimizer increase protein absorption? Jarrow markets the product to support protein absorption. Published research involving selected probiotics and pea-derived protein has reported increased circulating essential amino acid levels following consumption. However, the magnitude of benefit may vary by protein source, individual, and formulation.* What does the two-hour protein absorption research show? The manufacturer references research in which circulating essential amino acid levels were measured approximately two hours after pea protein consumption. The probiotic-supplemented condition showed higher levels than the comparison condition. This is a measure of amino acid availability, not direct proof of increased muscle growth or overall protein absorption in every setting. How much protease does each capsule contain? Each capsule provides a 250 mg Protease Enzyme Blend with 87,500 HUT of labeled enzyme activity. What does 87,500 HUT mean? HUT stands for Hemoglobin Unit on the Tyrosine basis, a measurement used to describe protease enzyme activity under defined test conditions. It measures enzyme activity rather than the weight of the enzyme ingredient. What types of protease enzymes are included?
