This oil is rich in linoleic acid (gamma-linoleic acid) and linolenic acid (linoleic acid), as well as smaller amounts of other fatty acids such as linoleic acid and palmitic acid. Evening primrose is a plant native to North America. Its seeds are used to extract evening primrose oil, which is widely used in health products and medicines. Evening primrose oil is believed to have many health benefits, especially in regulating skin conditions and women's health.

What is DHA Algal Oil?

DHA Algal Oil:
Cultivate microalgae: First, select microalgae rich in DHA and culture it in a suitable medium. During the cultivation process, sufficient light, temperature, and nutrients must be provided to promote the growth of microalgae and the synthesis of DHA.

Harvesting microalgae: Harvest microalgae after it has grown to a particular stage. The method of harvesting usually separates the microalgae through physical processes such as centrifugation or filtration.

Extract DHA: Extract DHA from harvested microalgae. Extraction methods usually include solvent extraction, supercritical fluid extraction, or pressing. Among them, supercritical fluid extraction is a commonly used extraction method, which uses fluids such as supercritical carbon dioxide to extract DHA from microalgae.

Purification: The extracted DHA Algal Oil usually requires further purification to remove impurities, solvent residues, etc. The purification process may include distillation, freeze crystallization, filtration, and other steps to ensure product quality and purity.

Packaging: DHA Algal Oil is packaged and usually sold in soft capsule or liquid form after extraction and purification for easy use and storage.

Functions

Evening Primrose Oil:
Skin Health: Evening primrose oil is rich in gamma-linoleic acid (GLA), an Omega-6 fatty acid thought to be beneficial to skin health. GLA can promote moisturizing, reduce dry skin and itching symptoms, and help improve skin problems such as eczema and dermatitis.

Women's Health: Some studies suggest that evening primrose oil may have a role in regulating women's menstrual cycles. The GLA it contains is believed to affect estrogen levels in the body, helping to reduce symptoms of premenstrual syndrome (PMS) and menopausal discomfort, such as mood swings, breast tenderness, headaches, etc.

Joint health: Evening primrose oil may have some protective effects on joint health. GLA is thought to have anti-inflammatory properties and can reduce arthritis symptoms such as joint swelling, pain, and stiffness.

Cardiovascular health: Some research suggests that evening primrose oil may have cardiovascular health benefits. GLA can promote blood vessel relaxation, improve blood circulation, help lower blood pressure and lipids, and reduce the risk of arteriosclerosis.

Autoimmune diseases: Evening primrose oil is thought to have specific immune-modulating effects and may be helpful in autoimmune diseases. GLA can regulate inflammatory responses and reduce disease symptoms, such as rheumatoid arthritis, systemic lupus erythematosus, etc.

DHA Algal Oil:
Brain and nervous system health: DHA is one of the essential components in the brain and nervous system and plays a vital role in brain development, especially in infants and young children. DHA Algal Oil supplementation can provide sufficient DHA to help maintain brain function and cognitive abilities and improve memory, learning, and thinking skills.

Vision development and protection: DHA is one of the main components in the retina and is essential for visual development and maintenance of retinal function. Ingestion of DHA Algal Oil promotes retinal development, improves visual sensitivity, and helps protect the eyes from damage from blue light and oxidative stress.

Cardiovascular Health: DHA Algal Oil helps maintain cardiovascular health. DHA can reduce triacylglycerol levels in the blood, improve blood lipid metabolism, and reduce the risk of atherosclerosis. At the same time, DHA also has anti-thrombotic and anti-inflammatory effects, helping reduce cardiovascular disease risk.

Joint Health: DHA Algal Oil may have benefits for joint health. DHA has anti-inflammatory and antioxidant effects, which can reduce arthritis symptoms, such as joint pain, swelling, and stiffness, and improve joint function and mobility.

Immune regulation: DHA Algal Oil may have a specific regulatory effect on the immune system. Appropriate intake of DHA can regulate the function of immune cells, enhance the immune system's resistance, and help prevent infections and autoimmune diseases.

Infant and young child development: For nursing infants, the intake of DHA Algal Oil can provide the required DHA through breast milk or added formula milk to promote healthy brain and visual system development.
