Almost 30 days of use

I've been taking crushed tonic collagen powder for almost 30 days now, and I feel like there's definitely a difference in the bounciness/glow of my skin! I have pretty good skin in general, but as I've gotten older I can see some of the bounce decrease, so I decided to try collagen. This one is great because I mix it in with my morning coffee, and I can't taste it all!

Excellent product!

Best tasting and fast dissolving collagen powder I’ve tried and it works like a charm on skin and nails

never knew what bovine collagen was...

I had absolteuly ZERO idea that bovine collagen was made from cow HIDES.
I used to take vital protein's as it was cheaper, and I thought crushed tonic was a bit overpriced.

Now I completely understand why.

Never going back to bovine. Yuck.

all these baby hairs are growing in my baldspots.

way better than biotin

Clearer skin

I’ve seen such a difference with my skin after introducing collagen into my daily routine! I’ve been struggling with my skin the past 2 years but recently my skin has been so much clearer and glowy. LOVE Crushed Tonics assorted flavors! So easy to drink daily and on the go!

BEST hair supplements

I LOVE Crushed Tonics new hair boosters! I’ve been using it for a couple months now and my hair is growing so fast. Plus it looks so shiny and healthy. I’ve tried Biotin hair supplements in the past but they always make me break out. I love that their products are made with keratin and collagen instead!

Results after first bottle

I have long nails for the first time in a long time.

Thicker Hair

Not sure it's providing hair growth since I've only been taking it a couple weeks but my hair feels thicker

The card board box it comes in is very difficult to get open. And the black round box the product is in is over the top! I am sure there has to be a cheaper way to package.

Daily staple

I absolutely love the unflavored marine collagen from Crushed Tonic. I use it in my daily coffee and/or smoothie but it’s great in pretty much anything since it has less discernible flavor than even plain gelatin (I tried it plain, in water, to try the unadulterated flavor, and it’s similar to plain gelatin as I expected, but that’s not my favorite method). I noticed an immediate impact on my skin while the benefits for my hair and nails took a bit longer, but were definitely noticeable after 3 months. The tubbie is perfect for my daily routine, while the plain crushes are ideal for travel.

Very promising

Been taking keratin hair growth pills along with the crushes for about a month now and I'm already noticing some growth all over. So I'll keep taking for at least a year and see what happens.

Favorite part of my skin routine

I’ve been using Crushed Tonic for four months and it definitely works: my under eye hollows have filled in, my nails are growing in strong and healthy, and minor scrapes or cuts heal faster. I love the coffee too - it’s my first drink of the day (fixed with a little oat milk). Highly recommend to anyone interested in a collagen supplement!

Your loss if you don’t try

I‘ve been drinking this product for about 5 consecutive years, and now, my day cannot be completed without drinking a cup of CT. Besides every benefits mentioned in other reviews, I drink it as protein powder, quick breakfast, or late night snack. I get constipated easily, but after drinking CT daily, I use my toilet in the morning! I also introduced some of my friends to this product, and they all loved it. The key is to drink it everyday to see the result. TRY IT for 3 months and you won’t regret.


The best coffee hands down and you’re getting the benefits of collagen!

always magic

I love this collagen. My brow specialist saw the difference (my eyebrows grow in a lot faster) and my head-hair does too. My skin has smoothed out and I will take this stuff until I DIE.

Can't wait for the tubbie to return but I love how on-the-go friendly these refills are.

I lost my hair due to chemotherapy. Ever since I started drinking collagen my hair started to grow faster and now adding the hair pills, it’s growing faster. People have been complementing me on my hair. Thank you for the pills
