Why a glucose disposal agent
Carbs aren't the enemy. How your body handles them is what matters.
Seven ingredients. One job, around carb meals.
GDAid is a companion for your carb-based meals. Take it before carb-heavy meals and let clinically studied ingredients provide support.*
- 01
Supports healthy glucose metabolism
Helps your body use carbs as fuel. GlucoVantage® dihydroberberine, Chromax® chromium and Ceylon cinnamon support healthy glucose metabolism and blood sugar levels already within the normal range.*
- 02
Supports nutrient use
Fuel to the muscle. InnoSlim® (astragalus and Panax notoginseng) supports your cells' take-up and use of glucose, along with complementary bitter melon, so more of what you eat goes to work.*
- 03
Supports metabolism and the liver
Rounds out the formula. CaloriBurn GP® grains of paradise supports thermogenesis and energy expenditure. Milk thistle at 80% silymarin supports healthy liver function.*

Still taking generic berberine? Upgrade to GDAid.

Questions
Before you decide.
Straight answers. If yours isn't here, contact us.
What is a glucose disposal agent?
A GDA is a supplement taken before carbohydrate meals to support how your body handles the glucose in that meal: healthy glucose metabolism and uptake into muscle rather than storage.* GDAid combines seven ingredients that each support that process, at meaningful doses.
When should I take it?
Two capsules with a full glass of water, 15 to 30 minutes before a carb-based meal, twice a day. Two servings a day is the full dose. If you take medication that affects blood sugar, talk to your doctor first.
Why dihydroberberine instead of berberine?
Dihydroberberine is the active form your body converts berberine into. GlucoVantage® dihydroberberine is recognized as the gold standard in its category for its superior absorption compared to generic forms of berberine.*
Is this a fat burner?
No. GDAid is built around nutrient use and metabolic balance. CaloriBurn GP® supports thermogenesis and Chromax® has been studied for body composition, but the formula exists to support how you handle the carbs you eat, not to replace diet or training.*
Does it stack with NAD Regen?
Yes. NAD Regen is the daily core, taken in the morning. GDAid is taken around meals. They work alongside each other, and alongside Cell Shield and GlyNAC+.*
How does the 90-day guarantee work?
Try it for up to 90 days from your order date. If it isn't for you, contact us and we'll refund what you paid for your first bottle. One bottle per product, per customer. Full terms.
Can I pause or cancel my subscription?
Yes, anytime, with no fees. Skip a delivery, change your frequency or cancel from your account. Subscribers save 10% on every order and get priority dispatch so you never run out.
When will it ship?
Orders ship within 24 hours from our fulfillment center in Wisconsin and typically arrive in 3 to 6 business days. Tracking is emailed as soon as it leaves.
