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!

So grateful that I found Crushed Tonic!

Also I feel like my mind is just a lot more clear! And of course my hair has grown so much and my skin is so glowy and clear! I think no mater your age or gender you would really enjoy this product! So if you have been looking for something truly HEALTHY and PURE to put into your body to help you hair, skin, nails, and overall mind and body health! Than you seriously need to try taking marine collagen by Crushed Tonic!

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.

Always on the best

With the proliferation of hydrolyzed collagen out there nowadays, i personally believe Crush Tonic continues to remain one of the best, if not the very best. Its results is undeniable.

Great in iced coffee!

I’ve been adding a small portion of the coffee+marine collagen to my daily summer iced coffee to keep it from getting watered down and to up my daily collagen intake. I typically mix it with the unflavored collagen so as to not over-caffeinate though.

Perfect for travel!

Although I prefer the tubbies for at-home use to cut-down on waste, the single-serve crushes are just perfect to make sure I can still get my daily collagen while I’m away from home and on the road since they’re the same great unflavored marine collagen that I love in the regular tubby, just travel-friendly!

I can't taste it!

Where else is No Flavor a plus? But really, it's the best plus ever about collagin. The unflavored IS unflavored. And it dissolves without being clumpy or gummy.

Easy, yummy-friendly protein

I struggle with getting in enough protein and collagen hasn’t done well on my stomach in the past. I love that the marine base makes this collagen so much easier for me to digest, along with the added probiotics and superfoods!
