Evening Primrose Oil

A natural plant oil rich in healthy omega-6 fats that eases monthly PMS discomfort and supports smooth skin.

What it is

Evening primrose oil comes from pressing the seeds of the evening primrose flower. It is rich in gamma-linolenic acid (GLA), an essential fatty acid that your body converts into comforting, soothing compound signals. In Her-Biotics PMS Support, it is combined with soothing herbs, vitamins, and friendly probiotics.

Also known as: Oenothera biennis, EPO, Gamma-linolenic acid (GLA) source

Key benefits

  • Provides GLA fats, which help soothe monthly breast tenderness and sensitivity.
  • Supports monthly comfort, so you feel less bloated and irritable before your period.
  • Nourishes your skin cells, which helps keep your skin hydrated, smooth, and flexible.
  • Helps replenish essential omega-6 fatty acids when your diet falls short.

Amplified by probiotics

Because evening primrose oil is a healthy fat, your body needs healthy digestive juices to absorb it. Friendly gut bacteria like Lactobacillus help break down dietary fats in your digestive tract, making it easier for your body to absorb GLA. At the same time, probiotics keep your gut lining calm, creating the ideal surface for absorbing healthy oils.

Typical dose

500–1,500 mg/day (providing 45–135 mg GLA)
