1. Introduction
Most people who supplement with protein are measuring the wrong number. The grams on the label tell you how much protein enters the body. They tell you nothing about how much the body actually uses.
Protein bioavailability, the percentage of consumed protein that is absorbed and utilised, varies significantly depending on the source, the formulation, and the condition of the digestive system. Standard whey protein, taken without enzymatic support, typically delivers between 60 and 70 per cent of its stated protein content to the body.
That means for every 25g serving, up to 8g may pass through the digestive system without being absorbed.
2. Why is digestion the limiting factor
Protein absorption begins in the stomach and continues in the small intestine, where large protein molecules must be broken down into smaller peptides and free amino acids before they can cross the intestinal wall and enter the bloodstream. The speed and efficiency of this process depend on the activity of digestive enzymes.
When digestive capacity is limited, or protein arrives faster than enzymes can process it, absorption drops. This is why many people experience bloating, heaviness, or discomfort after a protein shake. The digestive system is working hard to process a load it is not equipped to handle quickly.
3. What BioActin™ does
BioActin™ is a dual-enzyme system that directly addresses this. Actinidin, a naturally occurring protease derived from kiwi fruit, pre-digests protein by breaking peptide bonds before digestion begins in full. Amylase works alongside it to support the breakdown of carbohydrates. Together, they reduce digestive load and support more complete absorption.
Clinical evidence on actinidin shows improved gastric emptying and faster protein breakdown compared to whey consumed without enzymatic support. The result is higher bioavailability, less discomfort, and a lighter post-consumption experience.
