Since many of the components of rosehip powder are heat and light sensitive, great care is taken to process the rosehip powder in i-flex under carefully controlled conditions. The rosehips are first frozen upon harvest. Then a patented low-temperature drying process is used to ensure the rosehips are never unnecessarily heated to extreme temperatures. This careful, patented drying process preserves the active components of the gentle rosehip. It’s also what makes i-flex unique from other rosehip products, which are typically left in the hot sun to “dry out” the rosehip, causing it to lose its active nutrient value.
