How Much Collagen Should You Take Per Day?

The right collagen dose depends on what you're using it for. Skin and joint health studies use different doses, and more is not always better. Here's the evidence-based breakdown by application.

Collagen Dosage by Goal

Skin Health: 2.5–10g/day

The most well-researched consumer application. Effective doses from clinical trials:

• 2.5g/day: Significant improvement in wrinkle depth and skin elasticity (Proksch et al., 2014, Verisol® branded peptides)
• 5g/day: Commonly used in consumer products; multiple studies support this dose for skin hydration and elasticity
• 10g/day: Used in higher-dose studies; modest additional benefit over 5g not consistently demonstrated

Recommendation: 5g/day for skin health is cost-effective and evidence-supported. If using Verisol® specifically, 2.5g is the studied dose.

Joint Health: 10–15g/day

Joint studies use higher doses than skin studies:

• 10g/day: Used in the Clark et al. study of athletes with joint pain, showed significant reduction in activity-related joint pain over 24 weeks
• 15g/day: Used in Keith Baar's tendon studies, 15g taken 60 minutes before exercise improved tendon stiffness and collagen synthesis markers

Exception, UC-II (undenatured type II collagen): This works through a completely different mechanism (oral tolerance in the gut rather than peptide absorption) and is effective at just 40mg/day. Look specifically for this form if your primary goal is joint/osteoarthritis.

Tendons and Ligaments: 15g pre-exercise

The "Baar protocol" for connective tissue injury prevention and rehabilitation:

• 15g hydrolysed collagen 30–60 minutes before exercise
• Combined with 50mg vitamin C (or a glass of orange juice)
• Applied to relevant exercise session (not necessarily every session)
• Used for 6+ weeks for injury prevention, or during rehabilitation after tendon injury

Bone Density: 5g/day

A 12-month RCT showed 5g/day of specific bioactive collagen peptides (Fortibone®) improved bone mineral density in postmenopausal women more than calcium + vitamin D alone. This dose is consistent with general collagen use and doesn't require a separate protocol.

General Health / Anti-ageing: 5–10g/day

For general benefits without a specific application goal, 5–10g/day is the practical starting range. This covers most potential benefits without excessive cost.

Timing Matters: When to Take Collagen

With vitamin C: Always. Vitamin C is a co-factor for collagen synthesis, taking collagen without it is suboptimal. Add a squeeze of lemon, take it with orange juice, or use 100mg vitamin C supplement alongside.

Pre-exercise (for tendons/ligaments): Take 30–60 minutes before training. This times the elevated plasma amino acid peak to the remodelling stimulus of exercise.

Anytime (for skin and general use): Morning with breakfast or evening before bed both work. Consistency matters more than timing for skin applications.

How to Take Your Daily Dose

Most hydrolysed collagen peptides dissolve fully in hot and cold liquids without affecting taste when unflavoured:

• Stir into morning coffee or tea
• Mix into a smoothie
• Dissolve in warm water with lemon (adds vitamin C)
• Mix into overnight oats

Capsule forms are available but require taking 5–10 large capsules for a 5–10g dose, powder is more practical.

The Bottom Line

• Skin: 5g daily (or 2.5g Verisol® specifically)
• Joints (hydrolysed): 10–15g daily
• Joints (UC-II type II): 40mg daily
• Tendons/ligaments: 15g pre-exercise with vitamin C
• Bone density: 5g daily

Always include vitamin C. Give it 8–12 weeks for skin results and 3–6 months for joint changes.
