A Powerhouse of Vitamin C
You may already know that vitamin C can help keep your immune system healthy. But thanks to its antioxidant properties and its ability to stimulate collagen production, vitamin C can also help keep your skin supple and your bones strong. Most edible seedlings of Brassica vegetables, including kale sprouts and kale microgreens, are packed with vitamin C.
However, there seems to be quite some differences in the vitamin C content between different Brassica sprouts. According to a study presented at the International Conference on Food Innovation in 2010, broccoli and Portuguese Penca kale sprouts, for example, had significantly more vitamin C than Portuguese Galega kale sprouts. This study also revealed that if you're looking to get the most vitamin C out of your kale sprouts or microgreens, it is best to harvest them when they are around 15-16 days old as this is when their vitamin C levels peak. 💚
