Sea-Buckthorn (Hippophae rhamnoides L.) Sea-buckthorn berries are like freckles – all summer, they slowly collect their golden colour and the best of what nature has to offer. These berries contain almost the complete range of vitamins, provitamins, minerals and biologically active substances. So sea-buckthorn juice can truly be called a multivitamin – a few spoonfuls of juice provide us with all the necessary daily vitamins. Sea-buckthorn is the best fruit for strengthening the immune system. Athletes use the juice of these berries as legal doping, since the malic acid in combination with other physiologically active substances releases muscle energy rapidly. Sea-buckthorn is gold that belongs to all of us, and we become richer every autumn.
