This category covers two related but distinct supplement types: Glucose Disposal Agents (GDAs), which help your body manage carbohydrate intake, and digestive support products, which help your body break down and absorb what you eat. Both matter for anyone serious about nutrition, but they solve different problems.
What is a GDA?
A Glucose Disposal Agent is a non-hormonal supplement that mimics part of what insulin does — helping shuttle glucose from a carb-heavy meal into muscle cells for storage as glycogen, rather than it circulating in the bloodstream longer than necessary. In practice, this means more of the carbs you eat get used efficiently for training and recovery, with less spent managing blood sugar spikes. Products like Insight GDA are typically taken alongside your largest carbohydrate meal of the day — commonly pre- or post-workout — where the effect matters most.
Who needs a GDA
- Anyone eating higher-carb meals around training and wanting to use those carbs more efficiently
- Bulking phases, where large carbohydrate intake is common and glycogen storage efficiency matters
- Also useful during a cut, where better carb utilisation helps make the most of a lower overall carb allowance
What digestive support products do
Digestive enzymes and probiotics (like Osavi Digestive Enzymes + Probiotic) support your body's ability to actually break down and absorb the food and supplements you're taking — particularly relevant if you're eating large volumes of food or protein and experiencing bloating, discomfort, or inconsistent digestion. Apple cider vinegar complexes (like Prowise ACV Complex) are a related, if more general, digestive and metabolic support option.
Who needs digestive support
- Anyone eating high volumes of food or protein and experiencing bloating or discomfort
- People adding a lot of new supplements to their routine and wanting to support absorption
- Anyone whose digestion feels inconsistent despite a otherwise solid diet
How to use: GDAs are typically taken with your main carb-heavy meal; digestive enzymes/probiotics are usually taken with meals throughout the day — check individual product labels, as dosing and timing vary by formula.
