The new formula is more effective. We added a clinical dosage of 500mg of berberine, which is a significant addition to the efficiency of the product. We also included a more versatile form of digestive enzymes. The old version focused solely on carbohydrate and starch breakdown. We realize most people aren't consuming carbs alone, so we incorporated a more complete form of enzymes that break down protein, fats, and carbohydrates, making the formula much better. HumaSlin is the ultimate carb complement for athletes looking to maximize their anabolic window, accelerate recovery, and limit fat gain.
