Manufactured directly for cost savings, this product provides a convenient 120-capsule supply to support your daily wellness journey. ## Description Intrinsic Factor is an enzyme like substance secreted by the stomach. It is present in the gastric juice as well as in the gastric mucous membranes. Without the proper amount of Intrinsic Factor, orally administered Vitamin B-12 is not optimally absorbed and utilized. Persons with an Intrinsic Factor deficiency can not receive maximum benefit from the oral administration of Vitamin B-12. Wonder's TRINFAC-B provides Intrinsic Factor, Folic Acid and Methylcobalamin B-12 for enhanced absorption and utilization of orally administered Vitamin B-12.* Review: Big fan of this Trinfac-B for my GSD - 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. Review: It's helping my cat! - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K8BWZ04 | | Best Sellers Rank | #81,715 in Health & Household ( See Top 100 in Health & Household ) #330 in Vitamin B12 Supplements | | Customer Reviews | 4.6 4.6 out of 5 stars (317) | | Date First Available | May 9, 2014 | | Is Discontinued By Manufacturer | No | | Manufacturer | Wonder Laboratories | | Package Dimensions | 3.66 x 2.01 x 2.01 inches; 2.08 ounces | ## Product Details - **Brand:** Wonder Laboratories - **Diet Type:** Gluten Free - **Flavor:** Cherry - **Item Form:** Capsule - **Primary Supplement Type:** Vitamin-b ## Images ![Wonder Laboratories Intrinsic Factor with Folic Acid and Vitamin B-12 1000mcg - 120 Capsules - Image 1](https://m.media-amazon.com/images/I/61JNjgCRZZL.jpg) ## Questions & Answers **Q: is this the product with 40mg intrinsic factor?** A: Doesn't say... Folic Acid 800 mcg Vitamin B-12 1000 mcg I use this for my dog GSD 77 lbs who is EPI.. I give her 1 capsule with a meal and enzyme twice a day..Not sure what you need this for.. Hope this helps **Q: Is this product containing methyl folate?** A: Know there using folic acid because most of there's is for Dog's go to the labs website and you will see what i mean and 2/3 of the reviews on this page are of dogs. **Q: I tried ordering this product, and live in ca. warning comes up that product contains lead? i saw someone else ask this as well** A: California has the Prop 65 warning come up on MANY items (800!), if they POSSIBLY carry a risk of reproductive harm. Even though the amount of lead is miniscule, they still have to state it, even if it is lead that occurs naturally in the environment. While it is good to know, in this case it really doesn't mean anything harmful. https://health.thefuntimesguide.com/prop-65-warning-label/ **Q: Intrinsic factor is not listed on the ingredients, what is the source of the intrinsic factor?** A: That is true most intrinsic factors are porcine based. They are all animal based. I am surprised that they don't say it on the label. It is not a concern for me. Maybe contact the companies directly to get more info. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Big fan of this Trinfac-B for my GSD *by 5***T on March 28, 2017* We use this "Trinfac-B" by Wonder Labs to successfully supplement our German shepherd's food.

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. ## Frequently Bought Together - Wonder Laboratories Intrinsic Factor with Folic Acid and Vitamin B-12 1000mcg - 120 Capsules - PreserVision AREDS 2 Eye Vitamins, Lutein and Zeaxanthin Supplement with Vitamin C, Vitamin E, Zinc, and Copper, 120 Softgels (Minigels) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/16472040-wonder-laboratories-intrinsic-factor-with-folic-acid-and-vitamin-b](https://www.desertcart.us/products/16472040-wonder-laboratories-intrinsic-factor-with-folic-acid-and-vitamin-b) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
