  1. Natural vs synthetic vitamin E in fish oil supplement?

    General Dog Forum
    I saw there's two different types of vitamin E: d-alpha-tocopherol ("natural") and dl-alpha-tocoperhol ("synthetic") Does it matter which one you give your dog, and why? Could you please share your recommendation for a good fish oil with the right type of vitamin E? Thanks! PS. I also posted...
