In this empowering episode, Vanessa sits down with Dr. Shiloah Kviatkovsky, a leading researcher in collagen supplementation, protein metabolism, and connective tissue health. Together they unpack what actually works when it comes to optimizing protein intake, timing, and supplementation for women focused on fat loss, muscle retention, and active aging.
This conversation covers everything from satellite cells, myonuclei, and muscle protein synthesis to collagen peptides, tendon repair, and skin rejuvenation. Dr. Kviatkovsky shares her latest research on:
-
The anabolic differences between animal and plant proteins
-
Sex-specific protein metabolism
-
How collagen supports joint health, recovery, and visible skin improvements
Vanessa also shares her personal use of Tone Collagen (get 15% off with a subscription) which includes hyaluronic acid and clinically proven peptides that reduce the appearance of fine lines and wrinkles while supporting tendon and ligament resilience. Backed by science and daily routine–approved, it’s a supplement that works for both performance and beauty.
If you’re looking to understand how to use collagen and protein strategically for fat loss and body composition, this episode delivers the truth straight from one of the most respected researchers in the field.

| 0:00.0 | Welcome to the optimal protein podcast. I'm Vanessa Spina. |
| 0:05.3 | Hello, my friends. Welcome back to the optimal protein podcast. I'm your host, Vanessa, and today we have a very exciting episode, diving deep into the science of collagen, connective tissue health, skin health, protein metabolism with none other than Dr. Shiloh K. |
| 0:23.6 | Dr. K is a powerhouse researcher and expert in muscle protein synthesis, sex-based |
| 0:29.4 | differences in protein metabolism. She's also one of the leading researchers when it comes to |
| 0:34.7 | collagen's impact on recovery, connective tissue, and active aging. |
| 0:38.8 | In today's episode, we get into all of her research from comparing beef and plant-based |
| 0:45.0 | alternatives on muscle protein synthesis, why collagen is not just about beauty, which it is, |
| 0:52.1 | but also tendon and joint health, and how to optimize protein |
| 0:56.4 | for women at every life stage, especially when it comes to fat loss and body recomposition. |
| 1:02.9 | This conversation is incredibly validating if you've been focusing on high quality protein, |
| 1:08.7 | resistance training, and supportive supplementation, |
| 1:12.0 | especially collagen, to support your body composition goals and longevity. I am personally a |
| 1:18.4 | huge fan of collagen and one of the tools that I personally use daily to support both my |
| 1:25.2 | skin and connective tissue is tone collagen. It also contains |
| 1:29.6 | hylonic acid, which works synergistically with collagen to hydrate the skin from within. |
| 1:36.3 | And that is not just marketing. Clinical studies have been done on tone collagen, showing that |
| 1:42.4 | this specific formulation of collagen peptides helps reduce the |
| 1:47.1 | appearance of fine lines and wrinkles. And hyalronic acid is also clinically proven to reduce |
| 1:54.0 | fine lines and wrinkles as much as 15 to 20%. Now supplementing with collagen peptides is believed to actually stimulate the fibroblasts, |
| 2:04.4 | which are the specialized cells that actually make new collagen. So to have healthy, glowing skin, |
| 2:11.7 | you want there to be active remodeling in your skin tissue and the same goes in your joints and connective tissue. |
| 2:19.2 | So it's part of my overall strategy to support healthy joints and recovery as well as my |
