Dr. Weeks’ Comment: Sea buckthorn is a remarkable herb which seemingly does it all. As the research below indicates it protects fat soluble (“lipophilic”)and water soluble (hydrophilic”) parts of your body.
“…The exceptional value of sea buckthorn can be seen in the presence of both lipophilic antioxidants (mainly carotenoids and tocopherols) and hydrophilic antioxidants (flavonoids, tannins, phenolic acids, ascorbic acid) in remarkably high quantities…”
It also protects your cardiovascular system in times of hypercoagulation seen with COVID.
“…It has significant cardioprotective activity and exerts many positive healing effects on the cardiovascular system, including inhibiting blood platelet activation (especially platelet aggregation), lowering cholesterol concentration and blood pressure, and providing antioxidant activity.In addition, sea buckthorn has antibacterial and antiviral properties…”
We use Seabuckthorne to protect the eyes and our precious vision from illnesses like age related macular degeneration and retinal deterioration which depend upon Zeaxanthin and lutein for healthy sight.
“…In the case of sea buckthorn oil, of all the free carotenoids, zeaxanthin had the highest bioaccessibility (61.5%), followed by lutein (48.9%), making sea buckthorn oil a potential attractive source of bioaccessible xanthophylls...”
So read on and enjoy Sea buckthorn which is a powerful and unique oil optimizing human health.

Sea buckthorn as a source of important bioactive compounds in cardiovascular diseases
Abstract
Hippophae rhamnoides (sea buckthorn) offers many health benefits. It has significant cardioprotective activity and exerts many positive healing effects on the cardiovascular system, including inhibiting blood platelet activation (especially platelet aggregation), lowering cholesterol concentration and blood pressure, and providing antioxidant activity.In addition, sea buckthorn has antibacterial and antiviral properties. The leaves and fruits of the plant, and its oils, are sources of many bioactive substances including vitamins (A, C and E), unsaturated fatty acids, phenolic compounds, especially flavonoids, and phytosterols, which bestow positive effects on the cardiovascular system. This review article summarizes the current knowledge of the biological roles of sea buckthorn in cardiovascular diseases.

Sea Buckthorn Oil as a Valuable Source of Bioaccessible Xanthophylls
Cristina Tudor 1, Torsten Bohn 2, Mohammed Iddir 2, Francisc Vasile Dulf 1, Monica Focşan 3, Dumitriţa Olivia Rugină 1, Adela Pintea 1
Abstract
Sea buckthorn oil, derived from the fruits of the shrub, also termed seaberry or sandthorn, is without doubt a strikingly rich source of carotenoids, in particular zeaxanthin and β-carotene.In the present study, sea buckthorn oil and an oil-in-water emulsion were subjected to a simulated gastro-intestinal in vitro digestion, with the main focus on xanthophyll bioaccessibility. Zeaxanthin mono- and di-esters were the predominant carotenoids in sea buckthorn oil,with zeaxanthin dipalmitate as the major compound (38.0%). A typical fatty acid profile was found, with palmitic (49.4%), palmitoleic (28.0%), and oleic (11.7%) acids as the dominant fatty acids. Taking into account the high amount of carotenoid esters present in sea buckthorn oil, the use of cholesterol esterase was included in the in vitro digestion protocol. Total carotenoid bioaccessibility was higher for the oil-in-water emulsion (22.5%) compared to sea buckthorn oil (18.0%) and even higher upon the addition of cholesterol esterase (28.0% and 21.2%, respectively). In the case of sea buckthorn oil, of all the free carotenoids, zeaxanthin had the highest bioaccessibility (61.5%), followed by lutein (48.9%), making sea buckthorn oil a potential attractive source of bioaccessible xanthophylls.

[Sea buckthorn (Hippophaë rhamnoides L.) as a vitamin C treasury]
Sandra Urbaniak 1, Julia Kaźmierczak-Barańska, Bolesław T Karwowski
Abstract
Sea buckthorn is a plant which in numerous biologically active ingredients, such as: vitamins, flavonoids, carotenoids or unsaturated fatty acids, having a beneficial effect on human health. This plant deserves special attention, due to the presence of stable vitamin see. Sea buckthorn juice can therefore successfully replaced lemon in the daily diet. Due to the high content of vitamin C and flavonoids, sea buckthorn fruits are a valuable role material with antioxidant properties. Importantly, sea buckthorn retains its properties even after cooking or drying. The aim of this article is too approximate the health promoting properties of sea buckthorn resulting from the content of a large number of compounds with antioxidant properties, with particular emphasis on the vitamin C, which in the case of sea buckthorn is characterized by high stability.

Why is sea buckthorn (Hippophae rhamnoides L.) so exceptional? A review
Zuzana Ciesarová 1, et al
Abstract
Sea buckthorn (Hippophae L.) is a valuable, multipurpose plant extensively grown in Asia, Europe and Canada. In order to use it in the best way for products of human nutrition, it is necessary to recognize its positive aspects and to eliminate the negative ones. The exceptional value of sea buckthorn can be seen in the presence of both lipophilic antioxidants (mainly carotenoids and tocopherols) and hydrophilic antioxidants (flavonoids, tannins, phenolic acids, ascorbic acid) in remarkably high quantities. Some of the main nutrients, especially lipids of advantageous fatty acid composition, contribute to nutritional benefits of sea buckthorn products for a consumer as well. This review article focuses, besides the above mentioned compounds and vitamins, also on other important components, such as sugars, sugar derivatives, fibre, organic acids, proteins, amino acids and mineral elements. The article also deals with the effects of sea buckthorn components on the course of non-enzymatic browning of food and in vivo glycation. In addition, sensory perception of sea buckthorn and its constituents from the consumers point of view is discussed.

Abundance of active ingredients in sea-buckthorn oil
Aleksandra Zielińska 1, Izabela Nowak 2
Abstract
This article describes sea-buckthorn oil, which is extracted from the well characterized fruit and seeds of sea buckthorn. The plant has a large number of active ingredients the properties of which are successfully used in the cosmetic industry and in medicine. Valuable substances contained in sea-buckthorn oil play an important role in the proper functioning of the human body and give skin a beautiful and healthy appearance. A balanced composition of fatty acids give the number of vitamins or their range in this oil and explains its frequent use in cosmetic products for the care of dry, flaky or rapidly aging skin.Moreover, its unique unsaturated fatty acids, such as palmitooleic acid (omega-7) and gamma-linolenic acid (omega-6), give sea-buckthorn oil skin regeneration and repair properties. Sea-buckthorn oil also improves blood circulation, facilitates oxygenation of the skin, removes excess toxins from the body and easily penetrates through the epidermis. Because inside the skin the gamma-linolenic acid is converted to prostaglandins, sea-buckthorn oil protects against infections, prevents allergies, eliminates inflammation and inhibits the aging process.With close to 200 properties, sea-buckthorn oil is a valuable addition to health and beauty products.

Biological properties of sea buckthorn (Hippophae rhamnoides L.) derived products
Eva Ivanišová 1, et al
Abstract
Background: Sea buckthorn is a good and possible source of a wide range of bioactive compounds with a positive effect on the human body, especially polyphenols and carotenoids.
Results: All the tested sea buckthorn products had a high antioxidant activity. The highest content of total polyphenols (204.26 mg GAE/g), flavonoids (30.00 mg QE/g), and carotenoids (0.34 mg/g) were identified in 100% sea buckthorn juice. Maximal values of the antioxidant activity were found using the DPPH method for 100% oil (8.75 mg TE/g) and molybdenum reducing power for tea (196.41 mg TE/g). All the tested products showed strong antimicrobial activityagainst the tested bacteria, confirmed by both methods – disc diffusion (especially for Yersinia enterocolitica CCM 5671) and minimal inhibitory concentration.
Conclusions: The pronounced antioxidant and antibacterial properties of sea buckthornproducts indicate the importance of sea buckthorn application in health promotion and agricultural practice.
