high-strength at 12% gla ,stronger than traditional evening primrose oil ,with 10mg vitamin e (83% nrv)evening primrose and starflower oil are some of the few natural sources of the essential fatty acids omega-6 and gamma-linolenic acid (gla). evening primrose oil is often recommended to women as it helps to regulate metabolic function, maintain hormonal balance and supports healthy skin. our formula is one of the strongest of its kind in the uk. by blending evening primrose oil with pure starflower oil, we’ve increased the gla content to 12%, whereas most standalone formulas contain between 8-10% gla. since gla is an unstable compound and prone to oxidation, we’ve gone to considerable lengths to retain the nutritional properties of our formula. our evening primrose and starflower oil provide 83% nutrient reference value (nrv) of vitamin e, which helps preserve the freshness and stability of the oil. we’ve chosen to formulate our evening primrose and starflower oil as capsules, not tablets because a soft-gel casing is better suited to oil-based materials. we insist on sourcing our raw materials in the most sustainable and effective way. we also use an extraction process which gently crushes the evening primrose seeds to eliminate any components that may affect the stability of the oil, leaving behind a premium-grade product. our starflower oil, on the other hand, is grown in the uk on farms working with nature - not against it - to produce the highest quality oils. we manufacture and package our formula in uk factories working to strict good manufacturing practice (gmp) to ensure we meet our strict quality standards. still unsure if our formula is the right choice for you? reach out to |our expert nutrition advisors//aadvice//class=f-brand !important|, who can help you pick from our extensive omega-6 offerings. read our guide to powerful plant compounds |here//b724//class=f-brand !important|.
