Health Benefits of Oysters

Martine 14 December 2025 5 min

A Nutrient Powerhouse

Oysters are far more than a refined delicacy. They are one of the most nutrient-dense foods in the world, gram for gram. A dozen oysters alone cover your daily needs for zinc, vitamin B12 and copper.

Zinc: Your Immunity Guardian

With about 74 mg of zinc per 100 g, oysters are the richest dietary source of this essential mineral. Zinc plays a crucial role in the immune system, wound healing and protein synthesis.

Omega-3: For Heart and Brain

Oysters are an excellent source of omega-3 fatty acids, particularly EPA and DHA. These essential fatty acids support cardiovascular health and promote cognitive function.

Low in Calories, Rich in Protein

An oyster contains only about 7 calories with significant protein content. It's an ideal food for those watching their diet.

Vitamins from the Sea

  • Vitamin B12: essential for the nervous system and red blood cell formation
  • Vitamin D: rare in food, it helps with calcium absorption
  • Vitamin A: for vision and skin health
  • Iron: oysters contain as much iron as red meat
  • A Sustainable Food

    Oysters filter up to 200 litres of water per day, improving marine ecosystem quality. Eating oysters also supports a production method that regenerates the environment.

    At Huîtres du Sud, our oysters are raised in the pure waters of the Leucate lagoon, a unique terroir that gives them exceptional mineral richness.
