The Nutritional Benefits of Seaberry/Sea Buckthorn
Nutritional Benefits of Seaberry
The vitamin C concentration in seaberries is higher than that found in oranges, strawberries, or kiwi. For example, oranges provide approximately 59mg of vitamin C per 100 gram serving. Seaberries have a concentration of vitamin C that ranges from 100-300mg per 100 gram serving.
[Note: One study shows that sea buckthorn fruit has a concentration of vitamin C (average of 695 mg/100g) that is approximately 12 times that of oranges.

Concentration of vitamin E in seaberries is approximately 202 mg per 100 g serving. Seaberries contain all of the natural isomers of vitamin E and, therefore, play an important role in the elimination of free radicals. The primary vitamin E isomer in the pulp of seaberries is α-tocopherol, and γ-tocopherol is the major vitamin E isomer in the seed oil of seaberries.
Additional vitamins A, B1, B2, B6, B9, B12, D, K, P
Minerals calcium (70-98 ppm), chromium, copper, iodine, iron (40-150 ppm), manganese, magnesium (150-240 ppm), molybdenum, phosphorus (110-133 ppm), potassium (140-360 ppm), selenium, sodium (20-80 ppm), zinc
Amino Acids According to a nutritional report by Food Research International, “A total of 18 out of 22 known amino acids have been found in sea buckthorn fruit, half of which are essential since they play a critical role in various processes within our bodies such as energy production, building cells and muscles, fat loss, and mood and brain functions.”
Carotenoids The seeds and berry pulp of seaberries have powerful antioxidant properties due to the high concentration of carotenoids. Carotenoids boost the body’s immune system and are efficient free-radical scavengers. The seaberry’s carotenoids are readily absorbed due to the oil present in the pulp and seed oil.
Omega Fatty Acids Seaberries are rich in omega-3 (alpha linolenic acid), omega-6 (linoleic acid), omega-7 (palmitoleic acid), and omega-9 (oleic acid).
Alpha-linolenic Acid (ALA) is plant-based omega-3. It is the short-chain fatty acid that the body converts into the longer-chained EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). The seaberry offers vegans a wonderful plant-based, delicious option to the commonly sought after EPA and DHA more regularly associated with fish oil.
Plant Sterols The concentration of sterols in seaberries, found in 1-2% of the seed oil and 1-3% in the soft parts of the fruit, may contribute to improved immune function and cholesterol control.

Why the whole fruit surpasses extracts
There are manifold synergistic effects within whole plant foods that we know very little about, which is why whole foods carry exponentially greater benefits than extracted components. For example, oils, when separated from their fiber and lignin rich packages (such as with nut and seed oils and olive oil) quickly go rancid, and have a very limited shelf life. It is the same with seaberry. Because we know so little, because the nutrients in fresh whole foods are delicate, we believe that it is best to consume the freshest possible whole food, for the greatest, health-promoting effect. Any time one extracts and concentrates a particular element from a source, the likelihood of toxicity, imbalance, and spoilage is present. Refined oils, refined sugars, and refined grains are examples of this kind of concentrated processing. Stay tuned to our website to learn more about this claim. The human tendency to render extracted products from whole, natural packages is ever-present, but the truth remains that such commodities are often harmful, rather than beneficial. For the best results, grow your own seberries, harvest them at peak ripeness, and freeze them in a low-oxygen environment, or enjoy them immediately! At Vermont Seaberry Company, we’ve done that for you, by freezing the berries just after harvest, in liquid form, where little oxidation can occur.
