Frequently Asked Questions (FAQ)
Q1: What is the difference between Turmeric Powder and Curcuminoids?
Turmeric powder is simply the dried and ground root, containing about 2-5% curcumin. Curcuminoids are the concentrated extract containing 95% of the active compounds, making it much more potent for therapeutic use.
Q2: Is your Turmeric Extract non-GMO and Allergen-free?
Yes, Aiherba’s Turmeric Extract is 100% natural, non-GMO, gluten-free, and free from common allergens.
Q3: What is the Minimum Order Quantity (MOQ)?
For bulk wholesale, our standard MOQ is 25kg (one drum). However, we provide 100g-500g free samples for R&D testing.
Q4: How do you ensure the heavy metal limits?
We implement strict raw material screening and use stainless steel equipment during extraction to ensure Lead, Arsenic, and Cadmium levels are well below USP limits.
