It contains over 190 biologically active compounds, including vitamin C (15 times more than an orange), vitamin A (three times more than a carrot), and vitamin E. It also has high concentrations of the rare omega-7, making up 40 percent of the berry. Typically only found in fish oil, omega-7 keeps free radicals at bay and promotes the production of collagen, a key building block for skin, hair, and nails. Sea buckthorn has been thoroughly researched in over 130 modern scientific studies that have found that this berry promotes health. Women throughout the ages have used the obliphica berry to protect themselves against the ravages of the sun and the elements. Founded on tradition and now based on extensive scientific research, sea buckthorn is one of the biggest functional whole food rediscoveries of the 21st century.
