Collagen Peanut Butter Banana Smoothie

I know I’ve said it so many times, but smoothies really are one of my favorite breakfast options. Making one is just so simple and quick which is great Monday thru Fridays when I am trying to get out the door as quickly as possible.

Collagen Peanut Butter Smoothie // The Krystal Diaries

Last week I shared some of my anti-aging tips, and one of them was I added collagen into my everyday diet. I use an unflavored collagen that mixes well into almost any liquid, iced coffee, teas, and oatmeals but my favorite is adding it to my smoothies. So today I’m sharing one of my go-to smoothie recipes I have many! If you love peanut butter and banana, you’ll love this collagen peanut butter banana smoothie.

I buy my Vital Proteins from Amazon, and one container lasts me a long time. I normally do one scoop a day, always in the morning. If I have hot tea at night, I might add a scoop of collagen to it.

    A peanut butter and banana smoothie sounds wonderful. I know chia seeds are such a big thing. I am sure this is very healthy.

    I haven’t tried collagen but it seems to be a 2017 trend. I rarely try a smoothie I don’t like.
