Vitamin A

Vitamin A provides your first line of defense against invading toxins since it establishes healthy skin and mucous membranes. Vitamin A is part of the powerful antioxidant group of nutrients. Beta-carotene and vitamin A actually destroy carcinogens (>cancer-causing substances).

The A-vitamin of berries varied from 200 to 300 mcg. ß-carotenoids 1500 mcg/100 g (3.5-ounce) and α -carotenoids 700 mcg/100 g. The Total carotenoids content ranges from 30 to 40 mg/100 g of berries and the carotenoid levels range from 9 to 35 mg/100 g of berries. Table of Contents

Seabuckthorn Berry Oil provides 122,400 IU/100g (=16 470 IU/ tablespoon) of beta-carotene, which is perhaps the most abundant source of beta-carotene (see Table 1) among all other food sources.

Vitamin C

Vitamin C is one of the most important of all vitamins. It plays a significant role as an antioxidant, thereby protecting body tissue from the damage of oxidation. Antioxidants act to protect your cells against the effects of free radicals, which are potentially damaging by-products of the body’s metabolism. Free radicals can cause cell damage that may contribute to the development of cardiovascular disease and cancer.

In conjunction with vitamin B1 and the amino acid cysteine, vitamin C helps to counteract the damaging chemicals produced in the body by alcohol, nicotine, exhaust fumes and the toxic heavy metal, cadmium.

On average, SBT contains nine times as much of the vitamin C with the anti-oxidative effect as oranges or lemons. Sea  buckthorn has three times as much vitamin C as blackberries and thus far exceeds them in this respect.The vitamin C content of the Seabuckthorn berries range from 100 mg per 100g of fruit to 2500 mg/100g of berries for the Chinese subspecies sinensis.

Vitamin D

Vitamin D is sometimes called the ''sunshine vitamin'' since it is made in your skin when you are exposed to sunlight. If you eat a balanced diet and get outside in the sunshine at least 1.5 to 2 hours a week, you should be getting all the vitamin D you need.

Sea buckthorn seed oils contain Vitamin D 2.0 mg/100g. The main function of vitamin D is in building bone, and more specifically in getting minerals to bone, a process called bone mineralization. Vitamin D has a few tricks to accomplish this, several related to commandeering calcium and phosphorus and boosting their levels in the blood, making them
available for bone work. These minerals, and a few others, are important in building bone because they are the key ingredients that make up bone tissue.

Vitamin E

Pulp after the juice and pulp removal (481mg/ 100g of berries). D-alfa-tocopherol (Alpha-tocopherol is the most active form of vitamin E in humans, and is a powerful biological antioxidant) is the major form of vitamin E in seabuckthorn oil. An extremely high level of alphatocopherol (1046 mg/100g pulp oil) was reported for a cultivar of subsp. mongolica from Altai (Jablczynska et al., 1994).

Excellent safety record, clinical trial dosages as high as 3,200 I.U. daily for periods of 2 years had no unfavorable side effects or toxicity indications.

Vitamin K

“K” for the Danish word, koagulation, or for Americans, coagulation, its primary function in blood. And if you're unfortunate enough to be bleeding, this is one vitamin you don't want to be missing because it helps your blood to clot to stop the bleeding.

It has been shown that vitamin K supplements reduce the loss of calcium from the bones of osteoporosis sufferers, and speeds the healing of healing of bone fractures. Supplements are sometimes given to patients before major surgery.
