4. Try Algae
The concentration of omega-3 fatty acids found in some fish is due to the microalgae they consume, which produces the oils. When fish is eliminated from a diet, athletes can use algae powders and supplements to get the adequate amount of DHA, one of the main nutrients found in omega-3s. Try adding a scoop of chlorella or Spirulina, a type of blue-green algae, to your smoothies or mixing it with rice and olive oil.
