SISU Evening Primrose Oil 1000mg Details
SISU Evening Primrose Oil 1000mg is a source of essential fatty acids for the maintenance of good health. Each softgel holds 1,000 mg of high-potency, cold-pressed, hexane-free evening primrose (Oenothera biennis) seed oil, standardized to 9% gamma-linolenic acid (GLA) and 73% linoleic acid. GLA is an omega-6 fatty acid that isn't common in the diet; SISU formulates this oil to support hormonal balance against PMS symptoms, healthy skin and the inflammation associated with arthritis. Tested for pesticides and herbicides. Contains no dairy, wheat or gluten. 180 softgels with a bovine gelatin shell. Made by SISU.

Who SISU Evening Primrose Oil Is For
- Women looking for support against PMS symptoms such as breast tenderness, headaches, cramping and mood swings
- People with dry, irritated skin conditions such as dermatitis and eczema
- Those wanting support against the inflammation associated with arthritis
- Anyone who wants a concentrated source of GLA, which most diets don't provide
- People rounding out an essential fatty acid routine alongside omega-3s
Who this product is NOT for:
- Vegetarians and vegans — the softgel shell is bovine (beef) gelatin
- Anyone looking for omega-3 (EPA and DHA) — evening primrose oil is an omega-6 source; choose a fish or algae oil instead
- Pregnant or breastfeeding women, unless a health care practitioner advises it
Vitamart's Take
Evening primrose oil is one of the classic supplements for women's hormonal comfort and for skin, and SISU's version is a solid, high-potency choice: 1,000 mg of cold-pressed, hexane-free oil per softgel, standardized for GLA and tested for pesticides and herbicides. The 180-softgel bottle is good value for an oil that's usually taken daily. If you avoid beef products, note the bovine gelatin shell.
How SISU Evening Primrose Oil Compares
Evening primrose oil vs. fish oil
Evening primrose oil provides the omega-6 fatty acid GLA, while fish oil provides the omega-3s EPA and DHA. They do different jobs, and many people take both.
Evening primrose oil vs. borage oil
Both are plant sources of GLA. Borage oil is more concentrated in GLA, while evening primrose oil is the more traditional choice for PMS and skin support.
Softgel vs. a blended EFA formula
A single-ingredient oil like this lets you control your GLA intake separately. Blended omega formulas combine several oils in fixed ratios.
What Is GLA (Gamma-Linolenic Acid)?
- GLA (gamma-linolenic acid) is the active compound in the omega-6 family of essential fatty acids
- Many vegetable oils in our diet contain omega-6, but they don't provide much GLA
- Evening primrose oil is a rich source of GLA that isn't commonly part of the diet
- The fatty acids in evening primrose oil help balance the hormone-like prostaglandins
- Prostaglandins are factors in immune function and reproduction
How To Use
- Take as directed on the label or by your health-care practitioner
- Take consistently each day — essential fatty acid support builds over time
- Store in a cool, dry place away from heat and light
- Keep out of reach of children
