Sea buckthorn powder comes from dried sea buckthorn berries. The powder concentrates vitamin C, vitamin E, and the omega fatty acids 3, 6, 7, and 9. Many people take it to help maintain skin moisture and to support the immune system.
You can stir the powder into smoothies, yogurt, or water. Some use it simply as an antioxidant. Take it alongside a meal that contains some fat to help your body absorb the fat-soluble nutrients.
Digestive upset can happen. People who take blood-thinning medication should check with their doctor first because sea buckthorn carries a mild antiplatelet effect. Anyone pregnant or nursing should speak with a healthcare professional.
