PURSLANE · PORTULACA OLERACEA
Purslane: One of the Richest Plant Sources of Omega-3 Fatty Acids
Purslane is unusual among leafy greens for its high content of α-linolenic acid (an omega-3 fatty acid).
A 1992 study in the Journal of the American College of Nutrition quantified its omega-3, vitamin E, vitamin C, and glutathione levels and compared them favorably to spinach. Comprehensive reviews published in 2024 reaffirm that purslane ranks among the highest terrestrial plant sources of omega-3s and contains a range of antioxidants and phytochemicals.
Nutritional highlights
- Significant α-linolenic acid content
- Favorable omega-6 to omega-3 ratio in many analyses
- Additional vitamins, minerals, and antioxidant compounds
Research context
Most health-related findings remain preclinical (antioxidant, anti-inflammatory models). Human clinical trials specifically on purslane supplementation are limited.
Is purslane a replacement for fish oil?
No. It provides plant-based omega-3 (ALA), which the body converts inefficiently to EPA and DHA.
