Key Collagen FAQs

Key Collagen is hydrolyzed, which means the collagen is broken down into specific protein fragments called peptides. Collagen peptides are short chains of amino acids that are more readily broken down into a form that can enter the bloodstream upon digestion. Read below for more information on peptides.

Key Collagen contains collagen types 1, 2, 3, 5, and 10. Then we also add in high concentrations of the specific collagen peptides Fortigel, Fortibone, Tendoforte, and Verisol for very specialized additional benefits for cartilage, connective tissue, bone, and skin.

We test for heavy metals in every batch. We use only free range cattle from Germany, which doesn’t have the same heavy metal concerns that we have in the United States. 

Our collagen is processed at body temperature to assure no denaturing takes place of the protein/amino acids. We boil the collagen under a vacuum at body temperature to remove the fat that contains the stored toxins while not damaging the specific protein peptides.


The Key Collagen Difference: Peptides vs Amino Acid Profile

The bottom line is that the amino acid profile is not the best indicator of a good collagen. You need amino acids in a specific sequence to get the benefits you are looking for. Amino acids on their own do not make up tissue. Amino acids in a specific sequence make up specific types of tissue. The sequences are more important than the quantity of each individual amino acid. Key Collagen contains high concentrations of the specific collagen peptides Fortigel, Fortibone, Tendoforte, and Verisol for very specialized additional benefits for cartilage, connective tissue, bone, and skin.

Look for collagens that call out the types of collagen and any specific peptides they are using, so you know what areas of the body the product is meant to target. If a company doesn’t call out which peptides are included, you can assume the product is made up of one or two types of the cheaper peptides. These products might be great for hair or skin, but they will not satisfy the variety of collagen needs your body has – eg hair, skin, nails, bones, ligaments, and tendons.

Key Collagen was put together using clinical research to understand the doses of peptides needed to deliver the results we were looking for. We are confident that Key Collagen contains enough of the right material to support the body’s vast collagen needs. This is not just the normal hair, skin, and nail collagen. It does those things, but also supports the digestive tract lining, skin elasticity, joint health, placenta health, tendon and ligament strength, and bone strength and flexibility.

Searched out this very product and found it!

My friend and I went in search of a product with all four of the types of collagen in them and found them in this product. So far so good. I bought to help me heal a back issue I've had on and off for decades. I have only been using it now for about 2.5 weeks but it's super simple to use...mix with water and drink or just add to anything you want. I'm looking forward to having great results.

Knees feel better!

I have used other collagens for several years and this product about the last three months. I just returned from a vacation home with 16 stairs and after climbing up and down for 10 days, my knees do not hurt!! This has not happened before!!! The product isn’t cheap but I can confirm it really does work!!

To early to tell

I've only used a little over a month. Since hair nails take longer to grow out I would not expect to see results. But since you asked...when I purchased my second month's supply a few days ago I mentioned to the staff that I only got 26 days out of the supposed 30 day supply, like so many of the previous reviewers said, I was told that the scoop included holds more than the recommended dose of 17.5 grams! I'm now using about 2/3 of a scoop. For that reason I'm giving a 3. If after a few months I see positive results I'll amend this review.

Effective product and exceptional company

In January 2023 I wrote an honest review on my experience with Key Collagen. I loved the product but was frustrated with the label because it did not accurately reflect the serving size. Despite meticulous measuring and precisely following the directions, the collagen was completely used up within 3 weeks, month after month. The label clearly stated it contained "About 30 servings". Initially when I noticed the discrepancy, I emailed the company and was disregarded. After I wrote a review on January 7th, I received a prompt email from one of the owners apologizing for the lack of response to my previous inquiry. The owner stated they would look into the label and serving size, I explained I suspected the measuring scoop was the problem. I never expected any response so I was surprised and impressed that my complaint was acknowledged so quickly. Within a week, the owner reached out confirming they discovered the scoop was in fact the issue and it was being changed to match the serving size on the label. On February 20th I was informed the new inventory was available with the accurate measuring scoop.

I am elated that NutriKey ethically solved the problem and proved they do care about their label accuracy. This speaks volumes to the consumers of NutriKey products, not only is Key Collagen a top quality product but the owners have integrity to resolve an issue that an ordinary consumer brought to their attention. I appreciate their willingness to take accountability, investigate, communicate and implement a solution so quickly. Now I have confidence in NutriKey because they were responsive, communicative, and took action to solve a customer complaint they could have easily chosen to ignore. I will not hesitate to order NutriKey products in the future, they have proven they truly care about both their customers and their products.

One final experience, I decided to self experiment and try another brand of collagen to see if I noticed any difference between brands. I bought a 21 day supply and used it daily, within about a week or so, my joint pain (that had dissipated with Key Collagen) came back with a vengeance. My fingers, thumb and hands intensely ached again which impacted my ability to ski comfortably and practice yoga. Despite my discomfort, I continued to use the other collagen until it was gone. Once I resumed daily use of Key Collagen for about a week, my joint pain improved and I can absolutely confirm there is a big difference! I am relieved to report I feel better using Key Collagen. I am looking forward to continuing yoga and being able to hold my ski poles pain free with a firm grip! I love that Key Collagen is easy to use with no detectable taste or texture, it mixes well, completely dissolves and is easy on digestion. Highly recommend this product!
