I have used 1000 mg fish oil caps but I’m now taking two 1300 mg capsules of flaxseed oil. You can get the Flaxseed oil caps at Sams Club or Costco.
I bought some Smart Balance 50/50 Butter Blend. It has some flaxseed oil.
According to the label, a serving is one tablespoon. One serving has 320mg of ALA Omega-3 and 32mg of EPA/DHA Omega-3. Not that I actually understand that but it does look good.
