We are a Vancouver-based local business and we're in love with exploring healthy natural foods and sourcing them directly. We launched VanTasty Superfoods to sell our Premium Black Goji Berries. It changes color with different pH levels in water. 100% no artificial coloring, all color traces are naturally produced by Black Goji Berry fruit. It is rich in oligomeric proanthocyanidin (OPCs), protein, wolfberry polysaccharides, amino acids (18), vitamins (13 kinds), minerals, trace elements and other nutrients. We promised to provide high quality product at a reasonable price.
