  • Omega-3s are a group of polyunsaturated fatty acids, which are important in maintaining the fluidity of cell membranes and in promoting healthy signaling between cells.

  • Omega-3 supplements have been linked to a huge number of potential benefits, including better brain function, a reduced risk of blood clots, and lower chronic inflammation.
  • To get the full benefits of an omega-3 supplement, it’s best to ensure that it contains balanced levels of all three of the main long-chain omega-3s. Not all omega-3 supplements have significant levels of these fatty acids.
