what is sugar and starch intolerance?

Ever wondered why some foods cause discomfort and some don’t? The answer lies in a lack of digestive enzymes. Digestive enzymes are vital for breaking down nutrients, including complex carbs (sugars like starch and sucrose). Without certain enzymes, like those that tackle starch and sucrose, a food intolerance can arise, resulting in discomforts like bloating, gas, and abdominal pain.

But here’s the silver lining: You can provide your body with the missing enzymes it needs. No more worries about discomfort caused by starch or suger. Our product is designed to bridge the enzyme gap, offering you the solution you’ve been searching for. It’s time to reclaim your freedom to enjoy the foods you love without discomfort!
