 Natural Factors OmegaFactors Ultra Prim Evening Primrose Oil is derived from the highest quality evening primrose (Oenothera biennis) seeds, and extracted by cold pressing (expeller pressing) without the use of hexane or other solvents. This ultra-purified source of omega-6 essential fatty acids is highly stable and free of preservatives, offering 50 mg of gamma-linolenic acid (GLA) and 360 mg of cis-linoleic acid (LA) in each 500 mg softgel.

The essential fatty acids in Ultra Prim play an important role in the management of inflammation, cholesterol levels, hormonal balance, eye and skin health, and circulation. Ultra Prim may help prevent cardiovascular disease, reduce the risk of dangerous blood clots, and support healthy blood pressure.

Due to its beneficial effects on the immune system, cell membranes, and hormonal balance, GLA helps ease symptoms associated with premenstrual syndrome (PMS) and atopic eczema. GLA supports the health and appearance of the skin, can decrease inflammation, and even offers relief from dry eyes for contact lens wearers.

Evening primrose oil is an important source of GLA for anyone who wants to increase their intake of this omega-6 essential fatty acid.

Main selling features

  • Made from the highest quality evening primrose oil
  • Extracted by cold pressing (expeller pressing) without the use of external heat or harsh solvents
  • Ultra-purified to create a highly stable product without using preservatives
  • Provides therapeutic amounts of GLA to support optimum health

How it works

Evening primrose was called “the king’s cure-all” by early European settlers in North America and has long been used by Native Americans for its plethora of therapeutic effects. Modern science has discovered that many of these benefits appear connected to the concentration of GLA (up to 9%) found in evening primrose oil.

In the body GLA, a long chain fatty acid, is converted into a number of prostaglandins that influence numerous biological functions, including blood coagulation, blood vessel dilation, hormone production, cholesterol levels, inflammation, skin moisture, trans-epidermal water loss, and fatigue resistance. GLA has shown benefits for cardiovascular health, arthritis, skin disorders, premenstrual syndrome, and many more conditions.

A number of foods contain LA, the precursor to GLA, and the body can convert some LA to GLA with the help of various co-factors, including the enzyme delta-6-desaturase. However, a variety of other factors can hinder this process. People with diets high in sugar, alcohol, and trans or saturated fats; the elderly; and anyone with diabetes are especially at risk of having a low conversion of LA to GLA.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Comfortable, breathable, and flattering
Size: Small, Color: Pink/White/Khaki/Blue/Brown
I’m really pleased with this set of cotton women’s boxer shorts. The fabric is genuine cotton and feels lightweight and breathable without feeling flimsy or cheap. They’re comfortable enough to wear all day, especially if you prefer natural fibers. The elastic waistband is soft, comfortable, and also really cute, it doesn’t dig in or feel restrictive at all. The fit is true to size. I usually wear a small in underwear and these fit me perfectly. They feel secure while still looking sexy and relaxed at the same time, which is a great balance. I also really appreciate the earthy color palette, it feels calm, natural, and wearable rather than overly bright or synthetic. Overall, these are well-made, comfortable, and thoughtfully designed, and I’d happily order them again.

Lightweight and Comfortable.
Size: Small, Color: Pink/White/Khaki/Blue/Brown
These cotton boy shorts are really comfortable and soft. The material is breathable and feels nice on the skin, not itchy or tight. The size small fits true to size and stays in place without rolling up. I like the striped design and how they give good coverage while still feeling lightweight. Great for everyday wear and easy to wash. Overall, a solid and comfy underwear set.

Great toddler backpack!
Size: Small, Color: All Black
My daughter is in prek 3 and loves this backpack. Nice and small for her to carry. A full folder will fit with a little force, but if you’re looking for something to actually carry folders and books, maybe not the best.
