Frequently Asked Questions

What is aspartame and where is it used?

Aspartame is an artificial sweetener (E951) that is 200 times sweeter than sugar but contains no calories. It's commonly used in diet sodas, sugar-free gum, low-fat yogurt, protein bars, and tabletop sweeteners. It is not heat-stable, so it's not used in baked goods.

Do you provide Certificates of Analysis (COA)?

Yes. All COAs are issued directly by the manufacturing facility — not by us. This ensures authenticity and traceability of every batch we supply.

Can I mix different ingredients in one container?

Absolutely. Mixed container shipments are one of our specialties. You can combine 3–5 ingredients (e.g., Aspartame + Ace-K + Vitamin C) to optimize logistics and reduce shipping costs.

How do you ensure product quality?

We source only from certified manufacturers, require full COAs, and maintain direct communication with factories. We do not repackage or relabel — all products come in original factory packaging.

What markets do you serve?

We export to North America, Europe, Southeast Asia, the Middle East, and Africa. Our logistics team handles all documentation and customs compliance.
