What is Organic Goji Extract Powder?
Organic Goji Extract Powder (Lycium barbarum L.) is a high-potency 15:1 concentrate derived from Ningxia GI-protected goji berries. Utilizing dual water/alcohol extraction at ≤45°C, it delivers standardized bioactive compounds – including 40% polysaccharides and 200mg zeaxanthin per 100g – while preserving thermolabile antioxidants.
