"SEPHORA'S FAVORITE K-BEAUTY SUPPLEMENT"-ALLURE
Why Crushed Tonic?
Our mission is to make collagen more enjoyable and more effective — but also something truly delicious, easy to stick with, and proven to work.
Proven Glow In 30 Days
5g of clinically studied marine collagen per serving to support firmer, more hydrated skin, stronger hair, and healthier nails — in just 8 weeks. Think of it as your daily skincare, in a delicious sip.
5g of Collagen a Day
Formulated by Experts — our clinical results are based on daily collagen intake in the 2.5–5 g range, the dosage window most commonly used in published human studies.
That means you don’t need extreme amounts when it's collagen as high quality as ours — just a consistent, effective daily serving designed to support skin hydration, elasticity, and overall collagen renewal from within.
Finally, Wellness That Tastes Good
Too often, collagen ends up forgotten on the shelf thanks to chalky textures and strange aftertastes. Inspired by Korean flavors, our blends are designed to be smooth, balanced, and genuinely craveable — so your routine actually sticks.
Flavors By Korean Scientists
We partnered with Korean flavor scientists to craft drinks that taste incredible — even with collagen inside. With just 0 to 3.5 g of sugar per serving, they’re perfectly sweet: indulgent enough to enjoy, but balanced enough to avoid the crash or spike. It’s a daily treat you’ll actually want to drink — not another supplement that sits untouched in your pantry.
From juicy fruits to antioxidant-rich superfoods, our flavors are inspired by nature and designed to taste like a dessert-level upgrade. No strange aftertaste — just fun, craveable blends that turn your wellness routine into something you look forward to every day.

The Science
Behind the Magic
Collagen is the main protein that gives your skin its structure and strength.
Drinking it is scientifically proven to boost your body’s natural collagen production —leaving your skin firmer, more hydrated, and visibly smoother with fewer fine lines.
From Kitchen Accident to Collagen Obsession.
After a severe burn injury, our founder spent seven years working with Korean labs and nutritionists to rebuild her skin from within.
The result: clinically tested collagen that actually tastes amazing — no fillers, no metals, just results.

FAQ
TARIFF + PRICE INCREASE
Due to government tariffs, our production costs have increased by over 50% this year. Until now, we’ve absorbed these increases ourselves, but we’ve reached a point where we simply can’t carry the difference alone anymore.
Starting this month, we’ve made a modest adjustment of 10%+ increase across the line (with the exception of our Matcha, which has also unfortunately tripled in cost and now lands at $55 per large pouch).
Even with this change, we’re not certain it will fully cover what’s ahead—tariffs are ever-changing, and there may be further increases toward the end of the year.
Thank you so much for your continued support and understanding as we navigate this unpredictable climate.
Building Crushed Tonic has always been about bringing you the best collagen and wellness products possible, and I remain committed to making sure our quality never wavers—even when our costs do.
DIFFERENCE BETWEEN MARINE VS BORVINE?
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!
WHAT IS THE CLINICALLY PROVEN DOSAGE?
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!
CAN I TAKE YOUR DRINK MIXES IF IAM PREGNANT OR BREASTFEEDING
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.
AMOUNT + SERVING SIZE
Our pouches are all formulated a little differently, depending on the flavor—some are bolder, some lighter—but every single pouch always contains 150g of pure collagen.
Unflavored: 150g or 300g options.
Matcha, Turmeric, Lucuma, Coffee: about 210g net weight (150g collagen + flavor).
Sweet flavors: 150g collagen + up to 225g in flavor weight for a total weight ranging from 300-400g.
This just means the flavor profile varies—never the collagen. Each serving is built around 5g of collagen plus flavoring, which makes one scoop roughly 5g–15g depending on the SKU.
How to serve it:
For a lighter drink (and to stretch your pouch to ~30 servings), use ½ scoop with less water.
For a café-style tall drink, use 1.5–2 scoops.
For our sugar-free line, use 2 tsp for 5g collagen (the clinically proven dose) or 4 tsp for 10g collagen and a stronger taste.
WHY SHOULD I TRUST YOUR COLLAGEN?
Marine Collagen: You can test for quality of our marine 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.
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.
Grass-fed Bovine Collagen:
Our bovine collagen is hydrolyzed for maximum bioavailability: our bovine collagen boasts of 5,000 Dalton size for optimal absorption and effectiveness, compared to 9,000 Dalton size of other bovine collagen brands.
Our bovine collagen is also free of Growth Hormones, Antibiotics, BSE, TSE, Ethylene Oxide, Additives, Irradiation, Nitrosamines and Melamine.
WHAT CLINICAL CAN YOU SHARE?
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.
HOW LONG DOES IT TAKES FOR BENEFITS TO SHOW?
The benefits of collagen and keratin may take up to 7 days for skin and 14 days for hair..
