    I’ve used this forever in my feral colony cats and rescues that I bring inside to get them healthy. It’s amazing stuff, I’m glad Dr Belfield’s work is living on after his passing.

    I love this stuff and use it for my dog. Not only does it have vitamin C but there are other vitamins and minerals within this product. So glad someone is giving life to Dr. Belfields formulas. I was afraid they had gone for good.

    Always used it for my GSDs for years with great results. Happy, healthy and full of life. Great for my senior dogs.

    I am so excited to have these products back! Thank you Thank you Thank you!
    I have been using Mega C Plus on my Rottweilers from conception to death for 29 years!

    I’ve been using for more than a decade and my dogs have always had excellent hips. I love this product and the more I learn about canine nutrition I understand why this mineral/ vitamin supplement is important I understand why this balanced “recipe” works.

    I am so grateful this product is once again available. I’ve been using it for years and swear by the formula & its results.
    It has made a positive impact on my fur family. Minerals and vitamins are important for every body, human and animal alike. Thank you for carrying on Dr. B’s legacy.

    I’ve been using Dr. Belfield’s vitamin C products since 1998 and love them. So happy they are available again!

  8. Charla Smith-Worley (verified owner)

    Not quite as long as Patricia Covert, but 2002 was when I first used the Mega C Plus and dedicated Dr. Belfield supporter. Have his book and there was NO one like him. Thank you Ruth for keeping his spirit and love going!

  9. Jacquie Scherer (verified owner)

    I was afraid when Dr. Belfield passed that his vitamin formula would be lost. So happy it is available again. I’ve been using the product from Ruth for the last year, and see the same excellent results in my cats. Thank you Ruth for keeping this important product available for our four-legged friends.

    Dr Belfield was miles ahead of most of the medical and veterinary field in recognizing superior nutrition and optimal vitamin and mineral levels are the secret to a healthy life for animals and humans. Dr Belfield was the animal researcher fir Dr Linus Pauling twice Nobel Laureate
    Anyone who cares for their animals should be using MegaC for the their lifetime.

    A game changer. Witnessing my older cats revert to so much life and vigor makes me so happy to see. In such a very short time, we are able to notice the difference with all of our rescues. I am an advocate for the work of Dr. Linus Pauling, and am overjoyed with Dr. Belfield’s formulas. People and animals alike deserve a healthier, happier life together. 🙂 Thanks so much Ruth for keeping the torch burning. Much Aloha, T
