Buying Considerations

Types of Collagen

Type I: The most abundant collagen in your body, found in skin, bones, tendons, and organs. Supports skin elasticity and bone strength. Present in bovine and marine collagen.

Type II: Found primarily in cartilage. Supports joint health and flexibility. Primarily sourced from chicken.

Type III: Works alongside Type I in skin, muscles, and blood vessels. Supports skin structure and cardiovascular health. Found in bovine collagen.

Type V: Found in cell surfaces, hair, and placenta. Supports healthy pregnancy and cell membrane function.

Type X: Found in cartilage and supports bone formation and joint health.

Single-Source vs. Multi-Collagen: Single-source bovine collagen (Types I & III) is sufficient for most users focused on skin, hair, nails, and general wellness. Multi-collagen formulas are beneficial for comprehensive joint support or those wanting the broadest range of benefits.

Sourcing Quality

Grass-Fed, Pasture-Raised: Bovine collagen from grass-fed cattle is considered higher quality due to the animals’ natural diet and lifestyle. Look for certifications verifying these claims.

Wild-Caught Marine: Marine collagen should come from wild-caught fish, not farm-raised, to avoid potential contaminants and ensure sustainability.

Third-Party Testing: Look for brands that conduct independent testing for purity, heavy metals, and accurate label claims. Certifications like IGEN Non-GMO, NSF, and Informed Choice indicate rigorous testing.

Bioavailability

Hydrolyzed Collagen: All quality collagen peptides are hydrolyzed, meaning the protein chains are broken down into smaller peptides for easier absorption. This process makes the collagen 90%+ bioavailable.

Marine vs. Bovine Absorption: Marine collagen has smaller peptide particles and may absorb up to 1.5x more efficiently than bovine collagen. However, bovine collagen contains both Type I and III, while marine collagen is primarily Type I.

Vitamin C Synergy: Vitamin C is essential for your body to synthesize its own collagen. Formulas that include Vitamin C (such as Vital Proteins Advanced) or collagen with Vitamin C-rich foods may enhance benefits.

Dosage Guidelines

Standard Dose: Most studies showing benefits use 10-20g of collagen daily. Products with 11g per scoop allow for flexible dosing (1-2 scoops).

Timeline for Results: Collagen benefits typically appear after 4-12 weeks of consistent daily use:

• Skin hydration/elasticity: 4-8 weeks
• Nail strength: 4-12 weeks
• Hair growth: 12+ weeks
• Joint comfort: 8-12 weeks

When to Take: Collagen can be taken any time of day. Many people add it to morning coffee or smoothies for consistency. Taking on an empty stomach may improve absorption.

Dietary Compatibility

Keto & Paleo: Most collagen peptides are naturally keto and paleo-friendly, containing only protein with no carbs or sugars.

Whole30: Look for Whole30 Approved certification if following this program strictly.

Allergens: Bovine collagen is dairy-free but derived from cows. Marine collagen contains fish. Multi-collagen often contains eggs and fish. Check labels carefully if you have allergies.

Frequently Asked Questions

How long does it take to see results from collagen supplements? Most people notice improvements in skin hydration and nail strength within 4-8 weeks of daily use. Hair and joint benefits typically take 8-12 weeks. Consistency is key, as collagen provides building blocks your body uses over time.

Can I take collagen if I’m pregnant or nursing? Collagen is generally considered safe during pregnancy and nursing, but always consult your healthcare provider before starting any supplement. Choose single-ingredient formulas without added herbs or stimulants.

Does heat destroy collagen peptides? No. Hydrolyzed collagen peptides maintain their integrity up to approximately 400°F, making them safe to add to hot coffee, tea, soups, or baked goods without losing effectiveness.

Is marine collagen better than bovine collagen? Neither is definitively “better” – they serve different purposes. Marine collagen has smaller particles and may absorb slightly better, but bovine collagen provides both Type I and III collagen. Marine is ideal for pescatarians or those prioritizing skin benefits, while bovine offers broader support.

Can vegans take collagen supplements? True collagen only comes from animal sources. Vegans can take “collagen boosters” containing nutrients like Vitamin C, zinc, and amino acids that support the body’s own collagen production, but these are not actual collagen supplements.

Should I take collagen on an empty stomach? Some research suggests taking collagen on an empty stomach may improve absorption, but it’s effective taken with food as well. The most important factor is consistency, so take it whenever it fits best in your routine.

Can I take collagen with other supplements? Yes. Collagen pairs well with Vitamin C (enhances collagen synthesis), hyaluronic acid (skin hydration), and biotin (hair and nail support). Avoid taking high-calcium supplements, which may interfere with absorption.

How much collagen should I take daily? Most clinical studies showing benefits use 10-20g daily. Start with the recommended serving on your product (typically 10-11g) and increase to 20g if desired. There’s no evidence that higher doses provide additional benefits.

Why does my collagen powder smell or taste unusual? High-quality collagen is virtually tasteless and odorless. A slight natural taste is normal, but strong odors may indicate lower quality or improper storage. Marine collagen may have a faint fish smell in some batches, but it should not taste fishy.

Can collagen supplements replace protein powder? Collagen is not a complete protein (it lacks tryptophan) and should not be used as a protein powder substitute for muscle building. However, collagen contains unique amino acids (glycine, proline, hydroxyproline) that support functions distinct from those of standard protein powders.
