The Most Googled Collagen Questions, Answered by Wellness Experts

Collagen has gone from a buzzword to a beauty and wellness staple—but with that rise in popularity comes confusion. From conflicting TikToks to outdated info online, it’s hard to know what’s true and what’s marketing fluff.

Let’s cut through the noise.

Whether you’re curious about marine collagen, wondering about timing, or looking for the right formula to boost your skin, joints, or energy, we’ve gathered the most frequently searched questions about collagen—and asked our wellness experts to weigh in.

Grab your matcha, and let’s dive in.

1. What is collagen, and what does it do?

Collagen is the most abundant protein in your body and a major building block of skin, hair, nails, joints, bones, and connective tissue. Think of it as the scaffolding that keeps everything firm, supple, and strong.

As we age (starting around our mid-20s), natural collagen production declines. This leads to visible signs like wrinkles, sagging skin, joint discomfort, and slower recovery.

Supplementing with collagen—especially hydrolyzed marine collagen peptides—can help replenish what’s lost and support your body’s ability to maintain healthy tissue.

2. What are the benefits of collagen supplements?

Here are the top science-backed benefits of collagen:

• ✨ Smoother, more hydrated skin

• 🦴 Joint flexibility and reduced stiffness

• 💅 Stronger nails and shinier hair

• 🛌 Faster recovery after exercise

• 🧠 Cognitive and emotional balance (due to glycine content)

• 💧 Improved skin barrier and moisture retention

Radiant Renew contains Type I marine collagen peptides, which are especially beneficial for skin elasticity and hydration, as well as hyaluronic acid, elastin, vitamin C, coix seed extract, biotin, and ubiquinol—a powerful combination for total inside-out beauty.

3. Does marine collagen have side effects?

Marine collagen is generally well-tolerated and safe. Mild side effects—when they occur—may include:

• Digestive upset (rare and typically mild)

• Sensitivity for those with fish allergies (Radiant Renew contains marine-derived peptides)

If you’re pregnant, breastfeeding, or taking medications, always consult your healthcare provider before beginning any new supplement.

4. Marine collagen vs collagen peptides—what’s the difference?

"Collagen peptides" is a general term referring to hydrolyzed collagen that’s been broken down into smaller, absorbable pieces.

"Marine collagen peptides" are collagen peptides sourced specifically from fish skin or scales—typically Type I collagen, which is most abundant in skin.

Marine collagen is known for:

• Superior bioavailability (up to 1.5x more absorbable than bovine collagen)

• A more eco-friendly profile (often sustainably sourced from wild fish)

• Better for skin, hair, and nail benefits

Radiant Renew uses premium wild-caught Japanese marine collagen peptides, hydrolyzed for optimal absorption.

5. Is collagen OK for the thyroid?

Yes—and here’s why:

Collagen itself doesn’t contain iodine or directly impact thyroid hormone levels. In fact, many women with thyroid imbalances (like hypothyroidism) turn to collagen to support hair, skin, joint health, and gut integrity, which can all be affected by thyroid dysfunction.

It also provides glycine, an amino acid that supports liver detox pathways and hormone balance.

Pro tip: Pairing collagen with iodine—like our Pure Oceanic Root Iodine—can provide an added layer of thyroid and hormonal support.

6. Is collagen safe to take during pregnancy?

Marine collagen is generally considered safe during pregnancy, but it’s essential to:

• Choose a clean, well-tested brand (like Crane Wellness)

• Avoid blends with questionable additives

• Check with your OB-GYN or midwife before use

Radiant Renew is made in Japan with strict quality testing and no added sugar, gluten, dairy, or fillers—making it a gentle and effective choice.

7. When is the best time to take marine collagen?

Most studies show collagen absorption is effective whether taken morning or night. However:

• Morning: Great for energy, skin hydration, and habit consistency

• Evening: Can promote sleep and overnight repair (thanks to glycine)

Take it consistently, once daily. Mix into water, smoothies, or tea. Radiant Renew dissolves quickly and is nearly flavorless—no fishy taste here.

8. When will I see results?

Most users begin to notice changes within 3–6 weeks, especially in skin hydration and smoothness. For joint and nail health, results may take 8–12 weeks.

One clinical study found that hydrolyzed marine collagen increased skin elasticity by 40% in 8 weeks.

Pro tip: Take a before-and-after photo. You might be surprised at how much brighter and dewier your skin looks!

9. How long should I take collagen?

Collagen isn't a quick fix—it's a long-term wellness habit.

For lasting results, aim to take it daily for at least 3 months, and ideally make it part of your ongoing self-care routine. Your body will thank you with stronger skin, joints, and radiant resilience.

10. What makes Radiant Renew different?

Let’s compare:

Radiant Renew is more than collagen—it’s a beauty and skin nutrition formula, built to enhance glow, support elasticity, and power your collagen production naturally.

Bonus Questions:

Q: Can men take collagen too?

A: Yes—absolutely! Collagen isn’t just for women or skincare junkies. Men benefit just as much—especially when it comes to joint health, workout recovery, metabolism, and even hair and skin support.

As testosterone declines with age, collagen also drops, affecting everything from flexibility to the appearance of skin and muscle tone. Many men notice improved post-exercise recovery, fewer aches, and healthier nails and hair after consistent collagen use.

👉 Break the stigma—collagen is a foundational protein your body needs, regardless of gender.

Q: Can collagen cause breakouts or acne?

A: Not usually. Collagen is not known to trigger acne in most people. However, some low-quality collagen products contain added sugars, artificial sweeteners, or unnecessary additives that can spike insulin or irritate the gut—both of which may lead to skin flare-ups.

✨ Radiant Renew is clean, sugar-free, and made in Japan with strict quality control and third-party testing. If anything, the added hyaluronic acid and elastin can help calm and support your skin barrier.

Q: What should I look for in a collagen supplement?

Look for:

✅ Hydrolyzed peptides – for maximum absorption
✅ Marine source (Type I) – best for skin, joints, and beauty benefits
✅ Support nutrients – like Vitamin C, hyaluronic acid, elastin, biotin, and antioxidants to help your body build its own collagen

Avoid:

🚫 Fillers, artificial flavors, gums
🚫 Cheap bovine blends with no supporting nutrients
🚫 Unnecessary sugar or hidden ingredients

Radiant Renew checks all the boxes—plus it’s made in Japan under pharmaceutical-grade standards for quality and purity.

Q: Is marine collagen better than bovine collagen?

Both have their place—but here’s the breakdown:

• Marine collagen (Type I): Best for skin elasticity, hydration, hair, and nail strength

• Bovine collagen (Type I & III): More commonly used for gut lining, muscles, and cartilage

• Bioavailability: Marine collagen is up to 1.5x more absorbable than bovine collagen

Crane Wellness chose hydrolyzed marine collagen peptides for Radiant Renew because of their superior performance in beauty-from-within benefits. It’s sustainably sourced and works synergistically with coix seed, hyaluronic acid, and elastin to give your skin the full glow-up it deserves.
