Sweet Yogurt "Yakult" Collagen

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!

Most people notice early changes in 2–4 weeks (skin hydration/glow).

More visible results typically show in 6–8 weeks for skin elasticity and fine lines.

For hair and nails, expect stronger nails in 4–6 weeks and fuller-looking hair in 8–12+ weeks (a hair cycle). Consistency matters and results vary.

30 Servings.

All pouches will differ in net weight due to formulation needs per flavor:

• Unflavored pouches contain 150g of collagen, with no flavoring.
• Matcha, Lucuma and Coffee contain 150g of collagen + about 60g of flavoring.
• Milk and juice line contain 150g of collagen + about 100g to 200g of flavoring.

The more does not mean better, it just means we formulated for a different flavor profile (bolder, lighter etc) required for that specific flavor!

Collagen is a protein, so your body naturally processes and eliminates what it doesn’t need. That means it’s generally very safe — there’s no known toxicity level. However, taking very large amounts (over 20–30g per day) usually won’t offer extra benefits and may cause mild digestive discomfort in some people, like bloating or a full feeling.

For best effects, clinical studies show noticeable improvements with just 5g of collagen daily.

For even more optimal results, we recommend 10g (2 servings) per day for 14–30 days. You may notice smoother, more hydrated skin in as little as 5 days.

For deeper benefits — like reduced fine lines, stronger nails, and thicker hair — consistent use over 3 to 6 months is ideal.

Because our bodies can’t store excess amino acids, it’s best to take collagen daily rather than in large, infrequent doses.

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.

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.
