What a GDA Is

GDA stands for glucose disposal agent. It is a category of supplements people take around carb-heavy meals, especially during a bulk, a refeed or a high-carb training block. The goal is nutrient partitioning: supporting your body in sending carbohydrates toward muscle glycogen instead of storage. NutraBio's Unbound Series is its hardcore line, and GDA sits in its fat burner collection with no stimulants at all.†

Momordicin Bitter Melon Extract 1,500mg

Bitter melon is a tropical gourd used in traditional cooking and herbal practice across Asia. Momordicin is a branded bitter melon extract. Bitter melon is studied for its role in carbohydrate metabolism. At 1,500mg, it is the largest dose in the formula.†

Banaba Extract 600mg

Banaba comes from the leaves of the Lagerstroemia speciosa tree. It is best known for corosolic acid, a compound studied for its role in how the body handles carbohydrates. NutraBio uses 600mg per serving. It works alongside bitter melon as a second botanical in the stack.†

GlucoVantage Dihydroberberine 200mg

GlucoVantage is a branded form of dihydroberberine, a derivative of berberine. Dihydroberberine is studied as a more absorbable alternative to standard berberine, so a smaller dose can be used. Berberine compounds are among the most researched ingredients in the glucose disposal category. NutraBio uses 200mg per serving.†

GS4 PLUS Gymnema 200mg

GS4 PLUS is a branded extract of Gymnema sylvestre, an herb used in Ayurvedic tradition. Gymnema is known for gymnemic acids, which are studied for their role in carbohydrate metabolism and sweet taste. A dose of 200mg per serving rounds out the botanical side of the formula.†

Frequently Asked Questions

1. When should I take GDA?
   Take 6 capsules 30 minutes before a high-carbohydrate meal. If you eat more than one carb-heavy meal a day, NutraBio says you can use it as needed, but do not exceed the recommended dosage on the label. Low-carb meals don't need it. Most people time it with their biggest carb meal, often post-workout.†
2. Is GDA a fat burner or a stimulant?
   No. NutraBio states GDA contains zero stimulants, so there is no caffeine, jitters or crash. It is a carb-management and nutrient partitioning supplement, not a thermogenic. You can take it at night before a late carb meal. It also stacks with a stim-based fat burner if you use one, since it adds no stimulants.†
3. Who uses a GDA?
   GDAs are popular with lifters on a bulk, anyone running carb refeeds and athletes eating high-carb diets for performance. They are also used by people who simply eat a lot of carbs and want support around those meals. GDA does not replace a sensible diet. Training and total calories still decide most of the result.†
4. Can I take GDA if I am on diabetes or blood sugar medication?
   Not without talking to your doctor first. Ingredients like berberine compounds, bitter melon, banaba and gymnema are studied for their effect on carbohydrate metabolism. Combined with medication, that can push blood sugar too low. Your physician needs to know before you start.

How to Take NutraBio GDA

Take 1 serving (6 capsules) with water 30 minutes before a high-carbohydrate meal. Use it as needed for multiple carb-heavy meals, but do not exceed the recommended dosage on the label. Avoid taking it before low-carb meals or while fasting. Do not use if pregnant or nursing, and see a physician before use if you have a medical condition or take prescription medication.
