portulaca

Portulaca, known scientifically as Portulaca oleracea and commonly as Purslane, is a succulent green often found in gardens and farmers' markets. Far from being just a weed, it is a nutritional superstar, holding the title of the richest known plant source of Omega-3 fatty acids (ALA). It combines the anti-inflammatory power of fish oil with the bone-strengthening minerals of leafy greens, making it a vital addition to an anti-inflammatory diet.

Health Benefits & Sources

Why You Need It

  • Anti-Inflammatory Powerhouse: High levels of Omega-3 fatty acids help reduce systemic inflammation, benefiting heart and brain health.
  • Cellular Defense: Contains glutathione and melatonin, potent antioxidants that protect cells from aging and damage.
  • Bone Builder: Exceptionally high in calcium and magnesium, offering a dairy-free way to support skeletal strength.
  • Gut Soother: The natural mucilage in the plant helps coat and heal the digestive lining.

Deep Dive

Portulaca is unique because it stores water in its leaves, which concentrates its nutrients. Unlike many greens, it provides a significant amount of protein and healthy fats. Studies suggest that the specific antioxidants in purslane may help protect retinal cells, potentially supporting vision health over time. Because it grows so easily in hot climates, it is a sustainable, affordable superfood.

Natural Food Sources

You can find fresh purslane in Latin American or Asian markets, or grow it yourself. It has a crisp, slightly lemony taste.

Supplementation

If fresh purslane is unavailable, look for Purslane Powder or Extract Capsules. These are best taken with a meal containing fat (like avocado or olive oil) to help absorb the fat-soluble Omega-3s.
