I'm getting more emails than I can get to regarding collagen peptides. Here is my short answer.

Anonymous Q: Hi Travis,
I had sent the below question a couple weeks ago, I just watched the video you did recently regarding supplements but this topic was not addressed. If you have a moment I would still like to have your feedback on the below.
I know you are super busy so I really do appreciate your time!

Travis' Answer: I'm sorry I haven't responded. I can't keep up. My sincere apologies.
First, I don't use them but if I did and had a goal of fat loss I wouldn't consume these amino acids (Collagen Peptides) wrapped around extra calories.
I would suggest a high absorption rate collagen peptide-like these and in a capsule form:

You want several types of collagen and a quality product with a great absorption rate. One must be careful with calorie-containing supplements if the goal is fat loss. Often these types of supplements have minimal benefit but are helpful. Yet, when you wrap the beneficial components of the products in calories you are actually slowing your fat loss results.
The one above (link to Amazon) is the best I could find but I am sure there are others that are good too. Please watch out for low absorption products. Collagen products may be beneficial for hair, skin and nail health but manufacturers will take advantage of consumers during this fad phase.
The best course of action before collagen peptides would be to ensure adequate water/hydration intake, exercise, omega fish oils, and consuming adequate proteins like fatty fish.
Hope this helps.
