About Evening Primrose Oil (EPO)

Nutrina's Evening Primrose Oil (EPO) provides the body with essential fatty acids. The body cannot make these acids on its own, yet it needs them to produce hormones and other vital substances.

Evening Primrose Oil, (EPO), Oenothera biennis, is extracted from the seeds of Oenothera biennis, which is not actually a member of the Primrose family, but is part of the Willow herb family. The plant acquired the primrose name because its bright yellow flowers resemble primrose flowers, and its flowers open in the evening, hence its current name. The plant has a two-year cycle, and it is during the second year that the flowers appear, from which seeds are eventually harvested.

Plant History

The origins of the plant were in North America, from where it came to the UK by accident when cargo ships bringing cotton over, dumped the soil brought back as ballast, and seeds began to grow. The plant was officially introduced in 1614 into Europe, and rapidly became well known because of its useful health enhancing properties.

EPO was not examined closely, however, until 1919, when the gamma linolenic acid (GLA) content was reported in Germany, and consequently its effects on cell generation and heart health were soon monitored.* This led eventually to experiments that have given us the depth of knowledge that we have about this product today.

Circulatory Health

Evening primrose oil has become a well-known supplement since the 1980's. Current research suggests the oil is valuable in supporting liver and nervous system health.* Additional studies show that regular consumption of the oil helps to maintain healthy blood cholesterol levels and blood pressure levels that are already within the normal range.*   Evening primrose oil's nutritional effects are largely due to its primary active ingredient: gamma linolenicacid (GLA).

Prostaglandins

GLA is a fatty acid that the body converts to a substance called prostaglandin E1 (PGE1). PGE1 may have an effect on blood viscosity and act as a blood vessel dilator.*  GLA from evening primrose seeds may help because the body commonly blocks the production of prostaglandins. Without prostaglandins, the muscular, nervous and metabolic systems may not function at an optimum level.* GLA, by assisting the body in its production of prostaglandins, may help promote healthy functioning of those systems.*  In addition it may help maintain healthy blood pressure levels that are already within the normal range.*

Supplemental EPO

Linoleic acid, a common fatty acid found in seeds and nuts and most vegetable oils, should theoretically convert to PGE1. However, many variables can interfere with the conversion, including liver metabolism, aging, saturated fat, and inadequate intake of vitamin C, magnesium, zinc, and B vitamins. Supplements like EPO can help promote conversion, leading to more predictable formation of PGE1.*

Evening Primrose Oil Benefits

EPO has been shown to be beneficial for many aspects of health.*

• Premenstrual Syndrome (PMS) – has been shown to help reduce normal symptoms of PMS, including bloating and breast tenderness, reducing irritability and improving mood.*
• Very Dry Skin – dry skin may be helped by EPO and Fish Oils.*
• Circulatory Health – has been shown to help maintain healthy cholesterol and blood pressure levels already within the normal range, but may take several weeks or longer for maximum effects.*
• Joint Health – It is more effective when taken in conjunction with fish oils.*
• Immune System – low levels of essential fatty acids may prevent optimal interferon function, and result in less-than-optimal immune function.*
• Other conditions – Overweight and children's mood have been shown to be improved by EPO supplementation.
