Our Marine Collagen is clinically proven to enhance skin firmness, vitality, and hydration— delivering visible, radiant results in as little as 5 days.

Sourced from 100% fish, it’s hydrolyzed into ultra-small peptides with a molecular weight of just 4,000 Daltons, making it up to twice as bioavailable as standard collagen powders. This means your body absorbs it faster and more efficiently, maximizing benefits for skin, hair, nails, and joints.

It’s completely flavorless and dissolves seamlessly into hot or cold liquids, making it effortless to add to coffee, smoothies, or even plain water— without any clumps or aftertaste.

We never add fillers, preservatives, or anything artificial— just pure, premium-grade collagen. Every batch is rigorously tested for heavy metals and toxins, certified Halal and Kosher, and fully traceable back to the exact fish it came from.

Best Unflavored Marine Collagen!

This is the best unflavored marine collagen that I have tried! 💜 Odorless, colorless, and tasteless! ✨ I have tried other marine collagens made from fish and some have had an unpleasant sour smell and taste. But not this one - there's nothing unpleasant about it! Plus, it dissolves easily in hot or cold beverages, which makes it very easy to use 🙌 It also serves as a great base if you want to add your own flavor and sweetener, so it's very versatile and is a staple in my collagen arsenal 😸

Unflavored Crushed Tonic

Unflavored Crushed Tonic really is unflavored so it’s very easy to use. I’ve noticed a definite improvement in my hair, skin, and nails.

Love this!!

I drink a cup of tea with a serving of collagen every night and my skin has never been better and I've actually had people comment how fast my hair is growing! I don't think I could ever quit this product

2 Year Update!

I've been using this collagen for 2 years now and I feel like it has really helped my nails grow stronger, my extremely bleached hair grow out healthier and shinier, and my skin barrier heals well whenever I pick at my breakouts.

Quite pleased

It mixes very nicely and is clear once settled. There's practically no flavor! I've been adding it to lattes and coconut water and such

Love the unflavored collagen!

I love Crushed Tonic! This collagen actually dissolves and mixes well into my coffee or hot chocolate each day without a weird taste! I’m a big fan. I think it helps my skin and hair for sure! Highly recommend!

Truly Unflavored!

Just received my first order of the unflavored marine collagen and while I'll need to use it for a bit longer to know how it affects my skin/joint/gut health, I can 100% say that it is truly unflavored!! I was so worried that I'd be gulping down a viscous mess with my nose plugged, but I mixed this in my morning coffee and had no hint of a taste. Super impressed!!

I’ll never go without! Even my grandma loves it!

Crushed tonic is amazing. It’s the only collagen supplement I’ve tried that is actually flavorless and has produced results. I had a severe pain and tenderness after a cyanide burn on my scalp and CT’s marine collage has regrown my hair after 4 years of very little improvement to the point my dermatologist, hair dresser and PCP were shocked at my progress and all declared I’d make a full recovery. . I take this + their hair booster every day. My grandma also started taking this marine collagen to try and help her nails stop splitting and peeling and she’s been able to grow her nails out long, thick and strong at 80! A bonus is that her joint pain has decreased as well. We’re definitely fans for life ❤️

Best collagen

I love this collagen. It is tasteless which makes it so easy to add to any beverage. I love supporting a woman owned business and after hearing an interview with the owner of Crushed tonic, I learned so much more about the difference in quality of collagen supplements.

Love the quality of real collagen

I love crushed tonic, it feels like they are the only ones in the market with real collagen, I noticed my skin feeling fuller.

FAQ

  • Our purist flavors (matcha / coffee / lucuma) contain collagen and their ingredient main flavor ingredient listed, with no other sugars, flavors or ingredients. Our mylk flavors, vanilla bean, rose contain <5g sugar per serving. Please see our ingredients HERE

  • See our comparison chart side by side HERE.

    Both bovine (cow-derived) and marine (fish-derived) collagen have excellent benefits, but they differ in source, absorption, and targeted effects—which is why marine collagen is often more expensive. Here’s a breakdown:

    Bovine collagen comes from cows, often sourced from their skin, bones, or cartilage. It primarily contains Type I and Type III collagen, which are excellent for supporting skin, bones, and joints. On the other hand, marine collagen is derived from fish scales or skin and mainly contains Type I collagen, the most abundant type in the body, responsible for skin health and anti-aging benefits. Since Type I collagen is the most bioavailable and crucial for skin structure, marine collagen is often seen as superior for beauty benefits.

    Marine collagen has a smaller molecular size (4,000 Daltons in Crushed Tonic's marine collagen compared to 5,000 Daltons for bovine). Smaller peptides allow for faster and better absorption, making marine collagen particularly effective for skin health and anti-aging. While bovine collagen is still highly effective, it absorbs slightly slower due to its larger peptide size. (FYI - other bovine collagens are 9,000 Daltons!)

    Marine collagen is better suited for improving skin hydration, elasticity, and reducing wrinkles. It’s also popular for beauty-focused results, including strengthening hair and nails, and it supports bone density and joint health as well. Bovine collagen, by contrast, excels in promoting joint health, gut support, and general body repair. Since it combines Type I and Type III collagen, it’s particularly beneficial for tissues, muscles, and bones.

    Marine collagen tends to be more expensive because fish-derived collagen production is costlier. Additionally, it’s generally considered purer and less likely to cause inflammation or allergies compared to bovine collagen. Its superior absorption and beauty benefits also increase demand, contributing to the higher price.

    Crushed Tonic’s marine collagen is tested for zero heavy metals and is both kosher and halal certified, making it suitable for a broader range of consumers. Similarly, Crushed Tonic’s bovine collagen is also kosher and halal certified and free from growth hormones, antibiotics, BSE, and TSE, ensuring a clean and safe product.

    If your main focus is enhancing skin, hair, and nails, marine collagen may be worth the extra investment due to its superior absorption and high Type I collagen concentration. However, if you’re seeking more cost-effective and overall health benefits, such as joint and gut support, bovine collagen is an excellent choice. Ultimately, both are amazing quality sources of protein peptides and you can't go wrong with either!

  • Unflavored pouches contain 150g.

    Every flavored pouch has 150g of collagen, and additional flavoring.

    Matcha, Lucuma and Coffee contain about 185g NT WT.

    Rest vary from 200-300g, depending on flavoring requirements. The more does not mean better, it just means we formulated for a different flavor profile (bolder, lighter etc) required for that specific flavor!

  • Clinical studies show noticeable improvements with just 5g of collagen. For optimal results, we recommend taking 2 servings (10g of collagen) daily for 14 to 30 days. You may notice softer skin in as little as 5 days. For more significant results, such as reduced fine lines and thicker hair, consistent use over 3 to 6 months is ideal. Please make sure to consume daily as our bodies cannot store extra amino acids overnight!

  • For unflavored, mix 3 tsp (10g) into 1 tbsp of water.

    For matcha / coffee, mix 1 tbsp (15g) into 2 tbsp of water.

    For other flavors, mix 1-2 tbsp of powder into 2 tbsp of water. *Flavor profile will vary depending on amounts of water used. For best flavor, we recommend 2 tbsp of powder to 2 tbsp of water.

    Whisk aggressively in a bowl, or shake in a reusable bottle for best texture.

  • You can test for quality of collagen by adding it to a cup of water; it should dissolve perfectly as shown here.

    1. It is the most effective. Our tilapia fish skin collagen is the most bioavailable (AKA smallest in size and therefore best absorbed by our body). Tilapia skin also has the highest concentrations of protein and amino acids in their scales. Our bovine collagen also boasts of 5,000 dalton size, compared to 9,000 of other bovine collagen!

    2. It tastes best! Other collagen types are known for a stronger, gamier taste, while both of our collagen is essentially flavorless.

    3. Our collagen is sourced ethically and sustainably; because tilapia is so abundantly over-farmed (and the skin is so often discarded), sourcing collagen from tilapia is the most environmentally friendly.

  • Taking collagen supplements can be helpful during pregnancy and postpartum. Pregnant or breastfeeding women can experience brittle hair and even hair loss, so collagen can help restore hair back to health.

    As the baby grows, more and more pressure is put on your joints.

    Collagen peptides promote joint health by helping to repair joint matrix degeneration and improve long-term joint comfort and mobility, as well as helping to restore bone mineral density and support healthy bone metabolism.
    There’s a LOT of stress put on our joints as we carry the weight of growing baby.

    During breastfeeding

    The postpartum benefits of taking collagen can help with skin elasticity by helping to tighten back loosened skin on the stomach, and preventing stretch marks and hairloss.

    During breastfeeding, women are at risk of bone resorption; therefore, a daily collagen supplement may in turn reduce a woman's risk of osteoporosis later in life.

  • Yes!

    Collagen isn't just for women— as it is with all protein, both men and women can benefit from collagen!


    Our male customers’ love Crushed Tonic for its postivie impact on hair growth and hair loss prevention (especially thickening beard growth) and athletic performance by building muscles and bones.

  • Study 1
    Method: By measuring the time and quality of skin's ability to return to the original state after stretching and pulling it using a cutometer (a skin elasticity meter).

    At week 12, results showed that regular intake led to:

    18% increase in skin firmness

    27.2% decrease in skin elasticity

    22.8% increase in skin hydration

    Study 2

    Method: By measuring the shadows cast by one's wrinkles. At week 12, results showed that regular intake led to an average of -9.73% in length of respondents' wrinkles' shadows.

    Study 3

    Method: By studying perioral and Crow’s feet wrinkles on 95 healthy 55-60 year old females.

    At week 12, results showed that regular intake led to:

    improved skin elasticity

    reduced facial wrinkle appearance

    improved skin complexion homogeneity and radiance

    decrease of the mean score of facial wrinkles

    This study was conducted by CPCAD / Hospital of Nice (France) and biomechanical measurements of volunteers were controlled by certified dermatologists. It was performed according to French regulatory competent authority (ANSM) and approved by the local Ethical Committee (CPP).Study 4Method: By measuring the degree of deformation and the time required for the skin to return to its original state.

    At week 12, results showed that regular intake led to:

    improved skin elasticity

    decreased links

    improved skin complexion homogeneity and radiance

    The Cutometer® DUAL probe (Courage and Kazhaka, Köln, Germany) using a suction method measured a deformation perpendicular to the skin surface. A negative pressure of 450 mbars was applied to the skin through the probe for 2 seconds, followed by a relaxation period of 2 seconds. This cycle was performed 5 times.

  • The benefits of collagen and keratin may take up to 7 days for skin and 14 days for hair.
