1. Improved Digestive Health: Similase 90 Capsules contain a blend of digestive enzymes that can help improve digestive health by breaking down proteins, fats, and carbohydrates in the foods we eat. This can reduce symptoms of bloating, gas, and indigestion, and promote better nutrient absorption.
2. Reduced Inflammation: The digestive enzymes in Similase 90 Capsules can also help reduce inflammation in the digestive tract. This can be beneficial for those with conditions such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD). By improving digestion and reducing inflammation, Similase can promote overall gut health and help alleviate related symptoms.

The Active Ingredient Is: Protease (Digestive Protease)

Protease is a digestive enzyme that helps break down dietary proteins into amino acids, supporting normal protein digestion.

This formula uses plant-based protease as part of a broad-spectrum enzyme blend and also includes other digestive enzymes and artichoke extract to support intestinal health.

What Does Protease Do?

Protease contributes to protein digestion, aiding in the breakdown of proteins into absorbable components as part of normal digestive function. This enzyme blend helps support nutrient breakdown across a range of pH levels and may support overall digestive comfort.

Additionally, enzymes in this formulation work alongside other components to support broad digestion and mineral absorption through additional plant-based and herbal support, including artichoke extract.
