What it is

Classic Collagen is a powdered dietary supplement consisting of type I and III collagen enhanced with BioFit™, a unique, scientifically tested probiotic (healthy bacteria).

What makes it better 

1. 11 g of type I and III collagen per scoop, 41 servings (scoops) per container.
2. The collagen has been hydrolyzed to create a mixture of peptides (short chains of amino acids) that can be better utilized by the body. Peptides are considered the best form of collagen to supplement your diet with. 

3. Our collagen is unflavored and has a neutral taste that’s highly versatile. 

4. Contains BioFit, a unique, scientifically tested probiotic (good-for-you bacteria) that supports gut health and maximum absorption. BioFit consists of Bacillus coagulans, a probiotic with the unique ability to survive the harsh conditions of the upper digestive tract and reach the intestine safely, where it provides its benefits. 


How to use it

We recommend taking 1 serving of Classic Collagen 1-2 times daily. Mix it with 8 oz of water or your favorite beverage. Because hydrolyzed collagen is essentially tasteless and dissolves easily, you can add it to your protein shake, smoothie, juice, coffee, etc. 

 You can even add it to oatmeal and other foods. Experiment and see how you like it best. There’s no wrong way to use it.

Great Product

All of Old School Labs products that I have taken have been great. Their ingredients are also natural. They are not filled with artificial sweeteners and dyes like many other commercial brands that have sold out. I hope Old School Labs stays authentic.

Classic Collagen Review

Collagen is collagen - it's not always going to taste great. However, with OSL's collagen I know I am getting all the proper nutrition that my body needs. Supplements aren't always the easiest to get down but I found that the thinly refined collagen powder was not only easy to get down and digest but also easy to get in my shaker (or water bottle) and absorbed into my water. OSL's Classic Collagen along with their Vintage Base are always the best way for me to start my day!

Frequently Asked Questions

I’ve read that there are numerous types of collagen -1, 2, 3, etc. Which one is the best?
For the purposes of supplementation (e.g. enhancing the health of your joints, hair, skin or nails), there is no proof that any one type of collagen is the “best.”
I want to add Classic Collagen to my morning keto coffee, which I make with MCTs. Will the hot temperature damage the collagen?
Go ahead and add Classic Collagen to your keto coffee. It’s designed to work with hot or cold temperatures.
If I take Classic Collagen after my workouts (I want to help my joints recover), should I combine it with my regular protein?
Post-workout is a good time to take Classic Collagen. Try taking it within 1 hour of the end of your workout. You can take it by itself, or add it to your protein shake. For best results, stack with our Vintage Brawn™.
