Game changer
Perfect additive for coffee – noticeable difference in my hair line. Will continue to use this as well as their creatine – game changers.

Thorne Collagen Fit Review – Solid Addition to My Routine
I’ve been using Thorne Collagen FIT for just over a month now, mostly as part of my morning smoothie. It blends in well and adds a noticeable protein boost, which has been a great upgrade to my usual mix. While the powder is palatable enough to drink with water alone in a pinch, I do notice a subtle flavor and scent, so I’d recommend mixing it with something like a smoothie or juice for the best experience.As for results, I’ve noticed my skin looks a bit healthier lately… though it’s hard to say if that’s from the collagen or just feeling better and more healthy overall. Either way, it’s been a positive change. I’m not entirely sure what the nicotinamide adds in terms of benefit, but I trust Thorne’s formulations and overall quality. All in all, this has been a worthwhile addition to my supplement stack.

Throne = Quality. Clean, organic, tested, high standard supps.
Throne always makes good, clean, organic, tested products. No fillers, No BS, just high quality supplements. Don’t think I’ll ever have anything bad to say about this company. They do it right. Good all around.

Best product
5 Stars – Fantastic Supplement for Joint Health and Skin Elasticity!I’ve been using Thorne’s Collagen Fit for a few weeks now, and the results have been remarkable. Not only does this product help with joint health, but I’ve also noticed a visible improvement in my skin’s elasticity and overall appearance. The addition of Nicotinamide Riboside is a game changer, boosting my energy levels and helping with recovery after workouts.The powder mixes easily into my morning smoothie without any weird taste, and I love that it’s formulated with such high-quality ingredients. As with all Thorne products, I trust that I’m getting clean, effective supplements. Highly recommend for anyone looking to support their joints, skin, and overall well-being.

Easily soluble
Good product easily soluble. Noticed a difference in my hair& nails within first week of use. A bit expensive for a 30 day supply.

Excellent quality, exorbinant price
Product quality seems excellent. Was recommended by a friend for hair and joint support. I mixed it with my daily fiber supplement and was happy with how it actually helped that product dissolve better and become more drinkable. Went well in my daily protein shakes, although it does have a slightly salty taste which I don’t love. Only after the fact did I realize how expensive this product was – for my wife and I to each take a serving per day it would be $100/month (or $50/month for 1 person). While I would happily order this brand if money was not a concern at all, I found alternatives on Amazon that also appeared to be similar quality with less sodium for less than 1/2 the price.

THORNE Collagen Fit is simply the BEST!
If Top-Athletes worldwide are using it, then it must be worth the price and the Lab-Work behind this Collagen!

Love Thorne
I know it’s good for me, it has no flavor at all, it mixes in water or milk without clumping. I wish I knew what it did for me.

But product does not dissolve well. And there are other collagen products including a wider range of types that dissolve better.
