Is Collagen Too Good to be True?

Is-Collagen-Too-Good-To-Be-True.jpgIf you’ve spent any amount of time in the supplement aisle at the store in the last few years, you’ve probably noticed an increasing presence of collagen powders. Perhaps one of their taglines speaks to you: promises to erase those wrinkles, heal your leaky gut, make your joints feel as smooth as butter (healthy fats like butter WILL help hydrate your joints, by the way!), resolve that nagging shoulder injury, extend your lifespan, and much more. Maybe you’ve already even been adding it to your coffee every morning or to your post-workout smoothies in the hopes of addressing some of these issues. But is this just another example of a trend that is “too good to be true”? Or could there be real evidence to these claims? Let’s find out!

What is Collagen?

In its simplest terms, collagen is a type of protein. In fact, collagen is the most abundant type of protein in our body, making up about 30% of our total body protein. Most of this protein is in the form of our connective and soft tissues, such as the cartilage in our joints, our ligaments and tendons, our fibrous bone structure, our digestive tract, and our largest organ, the skin.

Why is Collagen so Important?

Collagen is higher in a few particularly important amino acids, most notably glycine. Glycine is considered a “conditionally essential” amino acid. This means the body can actually make its own glycine but we cannot make ENOUGH to meet our basic daily metabolic needs; that’s where collagen comes in!

Collagen “unlocks” glycine, but what’s so great about this one little amino acid? As it turns out A LOT!

  • Glycine is important for building and maintaining cartilage, and therefore joint health. Studies show that collagen supplementation reduced activity-related joint pain. (1)
  • Glycine is essential for moisturized, elastic, healthy skin. (2,3)
  • Glycine improves digestive health by keeping the lining of our intestines strong and intact. (4)   
  • Glycine has anti-aging effects by synthesizing glutathione, protecting against oxidative stress, and supporting liver detoxification. (5)
  • Glycine helps you when you’re ready to hit the hay as it’s  been shown to improve sleep quality. (6)

How to Get More Collagen

Collagen Rich Foods: Tap into the collagen/glycine benefits by eating the best animal-based foods that contain the soft and connective tissues of the animal, such as bone marrow, homemade slow-cooked bone broth (see how to make your own here), slow-cooked tough cuts of meat (like pot roast, oxtail, or ribs), skin-on and bone-in poultry, pork rinds, bacon, and sausage (usually made from tougher cuts of meat).

As always, the best quality and most nutrient-rich bones and meats are going to come from pasture-raised animals that have spent their lives in the sunshine and eating a species-appropriate diet. Healthy animals make the healthiest foods for us!

Supplementing with Collagen: If you’re struggling to meet your collagen needs through food alone, you may be wondering if a collagen powder would be a useful tool to help bridge that gap. It’s a bit more nuanced than a simple “yes or no,” and it bears repeating that we always recommend starting with the real-food sources of collagen listed above because you will get additional, complementary nutrients along with the collagen and glycine. For example, a mug of bone broth will contain collagen and will also contain key minerals for our health such as magnesium, phosphorus, potassium, and copper. A collagen powder will provide just that: collagen, without added nutrients.

A quality collagen powder, however, may be a more realistic way for some people to up their collagen and glycine intake and reap some of its benefits. Most collagen powders are sourced from beef, chicken, fish, bone broth, and/or egg shells. These powders are typically odorless, tasteless, and can be mixed into hot or cold liquids. A high-quality collagen powder will be processed at lower heats, and have no added binders, fillers, or potentially inflammatory ingredients (like corn or soy).

We recommend a collagen powder called Key Collagen. Key Collagen contains four patented Bioactive Collagen Peptides; Fortigel®, Fortibone®, Tendoforte®, and Verisol®. These collagen peptides are designed to promote vibrant skin and nails while also supporting healthy joints, bones, ligaments, and tendons.

One scoop of Key Collagen provides 17.5g collagen. Try adding this collagen powder to your protein smoothie, your morning cup of coffee or tea (don’t forget the heavy cream too!), mixed into some full-fat yogurt, or even as a bonus addition to some of your Nutritional Weight & Wellness favorite recipes (oatmeal almond balls, blueberry muffins, gluten-free pancakes, or protein smoothie). I recommend using collagen powder consistently for two to three months in order to fairly evaluate your personal results, whether for better digestion, healthier-looking skin, or a sounder night’s sleep!

I LOVE what the collagen powder I have does, but I find it is too high histamine for me. Is yours a high histamine powder?

Collagen and gelatin can be triggering for those with histamine intolerance. Usually this has to be a pretty severe case of histamine intolerance. Because our Whole Body Collage is so new, and because histamine intolerance is relatively rare, I do not have any anecdotal data as to whether the WB Collagen would trigger the same reaction as a more conventional collagen powder. So though we don't have data on this, a nutritionist reviewing your question intuitively guesses that it could. We have a couple of recommendations for you: 

1. Try the product and see if you have any kind of reaction. Try a small amount, maybe a Tbsp or two. If you have a reaction, return the collagen for a refund.

2) Get some collagen and nutrient in by making bone broth or meat broth (simmering tough cuts of meat with high connective tissue content) but limit the cooking time to just a few hours (or even just one hour), and then drink or freeze immediately.

My Natropath (who put me onto this product) suggested I take it at least half an hr away from other protein sources for best absorption... but I notice you make no mention of that here and actually recommend taking it in smoothies or with yogat? Is it best absorbed away from other protiens?

We have not found that to be true. Collagen is naturally occurring in protein sources. Maybe there is a specific reason your naturopath recommended it for you.
