Wonder Laboratories Intrinsic Factor with Folic Acid and Vitamin B-12 1000mcg - 120 Capsules

We use this "Trinfac-B" by Wonder Labs to successfully supplement our German shepherd's food. She eats Royal Canin 'Ultamino' kibble (Rx only) with one capsule Trinfac-B sprinkled on top of her food in the morning, plus one tiny 10 mg tab of prednisone. It feels like a miracle for us as she suffered from poor absorption of B12 and diarrhea off and on until we got her correctly diagnosed. She no longer has any diarrhea episodes and has slowly gained weight. Her feeding routine stays the same every day and we are rewarded by her beauty, love and loyalty and now, excellent health. Highly recommend. Update: July 5, 2017. Our GSD at her wellness exam had her blood taken for a blood panel. The results were excellent. We were very pleased to see as a result of sprinkling one capsule of the Trinfac-B on her kibble in the morning she now has "normal levels" of both B 12 and folate.

My cat suffers from IBS. I had no idea about this pesky illness except this cat of mine was always known for his runs. After much research, I started giving him vitamin B12. This brand. Daily. Well, zeus, who,s 17 years old, has been on it now for about 4 months . Low and behold, his poop is no longer like what it was before. I think he is as good as it gets at present. So long as he,s on this vitamin, old Zeus has been doing real well. I guess the little fella needed the B12 to help with his digestion n absorption n processing of foods. I recalled, n not too long ago, when Zeus was ill, the vet had to give him medication to calm the inflammation in his intestines, as well as antibiotics. He would get all well and then, the bad runny poop would start right back up again. What a nightmare that was for him. So, if your cat has IBS, this vitamin B12 can only help it.

I have a sensitive stomach. I really didn't believe anything would help as I have tried other products. This works for me.

Was looking for a basic supplement that has “intrinsic factor”. I have the MTHFR mutation and have found that this enzyme (it comes from pigs) is what I need to covert B6 for cellular metabolism. This one is the only affordable option.

This methyl B-12 product is excellent for dogs with medical issues who benefit from supplementation with methyl B-12, such as diabetic dogs to address diabetic neuropathy. It contains intrinsic factor, which enhances the absorption of B-12, and is actually required for many dogs with various medical conditions to be able to gain any benefit from oral capsules of B-12 (otherwise, those dogs would need to get B-12 injections). So far I believe this supplement has been helping my senior dog with health issues, and I will continue to purchase it for his health. Great alternative to B-12 injections.

These vitamins have everything you need. I used to take Perscription vitamins until the company closed. After much research found these are comparable. They make a difference for me

llego muy bien

Wonderlabs products are fantastic as is the service. I have been using Trinfac not only for my family but also for our dog that has Exocrine Pancreatic Insufficiency. We have been using Trinfac for over 5 years and my dog's B12 levels (check via Cobalamin (B12) blood tests, has repeatedly proven that this products works well, actually better than the B12 shots given by the vet in the past. Also Wonderlabs is great to deal with if you have any questions or concerns. They respond right away. Great product and one that we highly recommend to others on our Epi4Dogs.com website, https://www.amazon.com/Intrinsic-Factor-Folate-Vitamin-1000mcg/dp/B00K8BWZ04/ref=sr_1_1_a_it?ie=UTF8&qid=1482870152&sr=8-1&keywords=trinfac+b or [...] Olesia, President, Epi4Dogs Foundation Inc
