◆ Nutruoil® Flaxseed Oil/Linseed Oil

Definition

Flaxseed also called linseed (Linum usitatissimum) is a member of the genus Linum in the family Linaceae. Flaxseed typically yields 35-45% oil, containing 9-10% of saturated fatty acids (palmitic and stearic), about 20% monounsaturated fatty acids (mainly oleic acid), and more than 70% α-linolenic acid. Nutruoil® flaxseed oil is recognised for its health benefits due to its unique chemical composition and is one of the richest sources of polyunsaturated omega-3 fatty acids from plant sources, with linoleic and alpha-linolenic fatty acids being particularly abundant.

Nutruoil® flaxseed oil is obtained from Chinese flax seeds (Linum usitatissimum L.) by cold pressing virgin or cold refining.

Particularities of Nutruoil®Flaxseed oil:

■Source
Flaxseed or linseed (Linum usitatissimum L.) is one of the oldest oilcrops with multi-uses as indicated by its Latin name. It is widely distributed in the northern hemisphere, viz., Canada, USA, Russia, China and India for the production of seed oil and stem fiber. The colour of the seed coat of flaxseed depends on different planting techniques and growing environments, and is brown to golden yellow in colour.
Nutruoil® flaxseed oil is sourced from north-west China and, due to the environmental characteristics of the growing area, can provide high ALA content, non-GMO (unlike products from the Canadian region) flaxseed oil.

■Absorption and metabolism

Nutruoil® flaxseed oil is ingested by the human body through the oral cavity, stomach and small intestine where it is digested and absorbed by the body. The digestion and absorption of lipids in the gastrointestinal tract is a complex process. Because most lipids are insoluble in water, so they must be emulsified to enable them to contact the stomach and small intestine in the presence of a variety of lipolytic enzymes, after a series of related enzymes and bile salts in the intestinal lumen by bile acids and phospholipids into bile salt micelles, phospholipid vesicles, such as self-assembled structures, and then transferred to the intestinal epithelial cells for absorption.

Nutruoil®Flaxseed oil Health Benefits:

▶ Cardiovascular health

Polyunsaturated omega-3 fatty acids have a positive effect on reducing heart disease risk. The cardiovascular protective effect of flaxseed oil is attributed mainly to its lipid lowering as well as its antioxidant effects. Flaxseed oil from Richtek is rich in α-linolenic acid which is considered a natural precursor of EPA and DHA. Both EPA and DHA in the erythrocyte membrane increase in response to supplementation with flaxseed oil at rates related to the amount of the supplement.

▶ Metabolic effects 

Nutruoil®flaxseed oil consumption can decrease the risk of cardiovascular diseases such as cardiac arrhythmia in addition to its benefit to hypertensive and hyperlipidemic patients. The hypocholesterolemic effect of flaxseed oil, and its ability to improve lipid profile is attributed mainly for its richness in α-linolenic acid. 

▶  Skeletal muscle and bone health

The consumption of Nutruoil®flaxseed oil can improve skeletal muscle lipid composition and promote bone health. Diets high in C-3 polyunsaturated fatty acids have been shown to improve femur bone mineral density and bone strength. Flaxseed oil has also been found to ameliorate trabecular bone damage.   

▶  Central nervous system effects

Pre-treatment with flaxseed oil in a rat model of brain ischemia revealed for a potential neuroprotective effect on the motor cortex area following cerebral ischemic stroke. This effect was due to increase in the neurotrophic factors; brain-derived neurotrophic factor. Similarly, a dietary supplement of flaxseed oil exerted a promising effect in the treatment of depression.

▶  Anticancer

Omega-3 polyunsaturated fatty acid, α-linolenic acid, as well as its metabolites, EPA and DHA inhibit the growth of breast cancer cells in vitro.Flaxseed lignans demonstrate the ability to interfere with the phenotype of the malignant tumor, which affects its cellular characteristics.In addition, flaxseed lignans, by affecting connections in molecular signaling networks, modulate signaling cascades in various stages of cancer.  

▶  Anti-inflammatory

Nutruoil®flaxseed oil are important dietary sources of antioxidants due to their content of lignans, phenolic acids, and tocopherols. Flaxseed can lower the concentration of inflammatory markers. 

▶  Antioxiant

Flaxseed oil polyunsaturated fatty acids in the unsaturated double bond can be reacted with free radicals in the body, thereby reducing the production of peroxides or free radicals caused by the adverse effects on the human body. Flaxseed oil from Richtek contains α-linolenic acid, tocopherols, phenolics and other antioxidants that have the effect of scavenging free radicals. These antioxidant substances can be regulated to reduce the concentration of oxygen in some parts of the body, interfere with the occurrence of oxidation reactions, the timely removal of free radicals to control lipid peroxidation chain reaction.

▶  Anti-bacterial

It has been reported that increasing the amount of flaxseed oil in the human diet can reduce markers of immune function.Amelioration of acute pneumonia by increasing dietary supplementation with flaxseed oil polyunsaturated fatty acids.
