All About Collagen Peptides (And a Strawberry Collagen Smoothie Bowl Recipe!)

Collagen Peptides are all the rage these days, but what exactly are they and are collagen peptides something you should have in your diet?

What is collagen?

Collagen is a type of connective tissue and protein.  Amino acids make up peptides, and peptides make up proteins.  Protein is one of three essential macronutrients and is a necessary part of our diet.  The other two essential macronutrients are carbohydrates and fats.  Collagen is found in our cartilage, bone, teeth, and skin and provides strength and structure to our cells.  The term collagen is actually derived from the Greek word for glue!  Unfortunately, our body’s production of collagen declines as part of the aging process. Fibroblasts (cells found in connective tissue) degenerate and the tension within collagen complexes both decrease over time.  These factors both contribute to lowered collagen production as we age.  Exposure to free radicals like smoke, UV radiation, and pollution also negatively affect our collagen production rates.

What are collagen peptides?

Collagen supplements are an emerging health trend and aim to solve the issue of decreased collagen production.  The collagen is often sourced from cowhides or bone (think bone broth) which are chemically treated and then ground into a powder.  This process breaks down collagen proteins into smaller peptides.  Collagen peptide powders are similar to other protein powders because they consist of peptides and amino acids.  These substances are the building blocks of protein.  Because these supplements are made from collagen, they will help fulfill the actions of collagen in the body.  Or at least this is the idea that sets collagen peptide powders apart from other available protein powders.

What are the benefits?

These powders come with claimed benefits of improved growth and function of hair, skin, nail, gut, and joint tissues. Unfortunately, there is not much research supporting these claims available.  A study conducted on a group of athletes had positive results indicating an association between collagen supplementation and decrease joint pain.  While small, the study concluded that supplementation can aid in athletic performance by decreasing pain.  Additionally, another study researching skin function and collagen supplements showed significant increases in elasticity, firmness, and thickness of aged skin after 3 months of collagen supplementation!  There have not been many studies in humans studying collagen supplementation and gut health, but there have been some promising results seen in piglets! The results from these studies seem promising, however, much more research is still necessary before anything conclusive can be determined.

Ways of incorporating into food

In powder form, adding collagen to your daily meals is easy!  There is no definitive proof of the benefits of collagen peptide powders, but there are no major health concerns either.  If you wanted to try these products out for the proposed benefits, there is little risk.  As an animal product, you should use these powders in the same moderation you would meat or dairy.  Collagen peptides add protein to your diet without an excess of fat or carbohydrates!  The powder can be added to your everyday staples, such as a latte, as well as oatmeal or a smoothie bowl.  Collagen peptides can make your meals more filling with the addition of protein, without a surplus of calories!

Amazon Prime Day is here!!

Amazon has become a real shopping staple in our home and something we’ve come to rely on (hello free 2-Day shipping!!) I’m excited that Prime Day 2018 is here because it’s a chance to really get some amazing deals!

*I’ll be updating this blog post when I find new deals!*

Did you know that you could get $10 towards your purchase which would make my favorite Cuisinart Waffle Maker only $17?!

Or you could get this handheld spiralizer for less than $10 with your $10 credit!


You could also get this Stasher Bag (which I’ve totally been eyeing and am grabbing this deal now!) for free with your $10 credit!


Keep reading for how you score your $10 off!

What exactly is Prime Day? 

It’s a huge day of deals (36 hours actually!) where Amazon is discounting thousands of items on their website– but only for its Amazon Prime members! Think of it as a Black Friday or Cyber Monday but in July! The deals begin on Monday, July 16th at 3:00pm EST and run through Tuesday, July 17th.

Not any Amazon Prime member? Sign up here for a 30-day free trial and you’ll get access to the Prime Day deals!

How do I get a $10 credit to spend on Prime Day?

If you spend $10 at Whole Foods through July 17, you’ll receive a $10 credit on your Amazon account to use towards your order on Prime Day! I just went to Whole Foods on Sunday to grocery shop, so I’m excited to have at least $10 to spend today and tomorrow! Just make sure you have your Amazon Prime account linked to your Whole Foods app, and have them scan it at checkout.

What are some of the best deals on Prime Day?

Save 30% off on Amazon’s own brands

Did you know that Amazon has its own line of brands?

They are already really well priced goods, but on Prime Day they are discounted 30% off! Here are a few of their own label products that I’m planning to check out:
