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...
So I want to add a Vitamin E supplement for the dogs. I was wondering if there is a specific one for dogs, any brands recommended? I'd love to have Vitamin E on it's own, not as a multi-vitamin.
