Can Supplements Help Tendons Heal Faster? Collagen, Vitamin C, and Shockwave Therapy in Hinsdale

Short answer: Yes, the right supplements can help, as long as they’re paired with real treatment and the right kind of loading. Studies show collagen with vitamin C boosts the body’s collagen production, collagen peptides helped Achilles tendon patients recover faster alongside exercise, and in one randomized trial, people who took a collagen, vitamin C, and arginine supplement during shockwave therapy for Achilles pain had better results than those on placebo. At Adisi Health Center in Hinsdale, Dr. Steve Petzel pairs shockwave and other therapies with practitioner-grade supplement packages, and you can start with a free 20-minute phone call at (630) 887-1900.

Why are tendons so slow to heal?

Tendons are the tough cords that connect muscle to bone, like your Achilles, the patellar tendon below your kneecap, the rotator cuff in your shoulder, and the tendons on the outside of your elbow. They’re made mostly of collagen and have a much poorer blood supply than muscle. That’s why tendon pain (tendinopathy) can drag on for months, especially for adults in their 40s, 50s, and 60s.

To heal, a tendon needs two things: a signal to rebuild, and the raw materials to rebuild with. Treatments like shockwave therapy and progressive exercise provide the signal. Nutrition provides the building blocks.

Which supplements help tendons heal?

The best-supported nutrients for tendon healing are the ones your body uses to make collagen:

• Collagen or gelatin: supplies the amino acids (glycine, proline, and hydroxyproline) that tendons are built from.
• Vitamin C: your body needs it to form and stabilize new collagen.
• L-arginine: supports blood flow and is used in tissue repair.
• Zinc: involved in tissue repair and collagen formation.
• Omega-3s and curcumin: support a healthy, normal inflammatory response.

A 2023 scoping review of 16 studies found that several of these nutritional compounds may help in tendinopathy by easing inflammation and improving tendon healing, and may add to the benefits of standard treatment like exercise (Burton and McCormack, Journal of Sport Rehabilitation, 2023; PubMed 37146985).

What does the research say about collagen and tendon healing?

• Supplements plus shockwave for Achilles tendon pain (2012): In a randomized, placebo-controlled trial, everyone with insertional Achilles tendinopathy (pain where the Achilles attaches to the heel) received three shockwave sessions. The group that also took a daily supplement with arginine, collagen, MSM, vitamin C, and bromelain had significantly better ankle function at 2 and 6 months, lower pain at 6 months, and higher satisfaction than the placebo group. The authors concluded the supplement could improve the response to shockwave (Notarnicola et al., Advances in Therapy, 2012; PubMed 22923162).
• Collagen peptides for chronic Achilles tendinopathy (2019): In a placebo-controlled crossover study of 20 patients doing a calf-strengthening program, the group that took specific collagen peptides first improved more than twice as much on the Achilles function score (VISA-A) over the first 3 months, with no side effects reported. The authors concluded collagen peptides may speed up the benefits of a structured rehab program (Praet et al., Nutrients, 2019; PubMed 30609761).
• Vitamin C-enriched gelatin doubles collagen production (2017): In a randomized, double-blind study, taking 15 g of vitamin C-enriched gelatin one hour before a short bout of exercise doubled a blood marker of new collagen production. Lab-grown ligaments treated with blood from people who took gelatin also had more collagen and were mechanically stronger (Shaw et al., American Journal of Clinical Nutrition, 2017; PubMed 27852613).
• Systematic review of 8 randomized trials (2026): Collagen supplements (15 to 30 g a day) taken with vitamin C (at least 50 mg) alongside resistance training increased tendon size and stiffness, a sign of tendon remodeling, with the review rating this as strong evidence (Buchalski et al., Journal of Functional Morphology and Kinesiology, 2026; PubMed 41900537).

Can supplements make shockwave therapy work better?

That’s exactly what the 2012 Achilles trial above tested, and the supplement group did better. It makes sense: shockwave sends acoustic pressure waves into the tissue to increase blood flow, break down scar tissue, and kick-start new collagen production. Supplements give that rebuilding process more of what it needs.

Supplements don’t replace shockwave or exercise. Every positive study above combined them with active treatment or loading. Think of them as the support crew, not the main event.

What’s in the Adisi Shockwave & Soft Tissue Healing package?

Dr. Petzel put together practitioner-grade packages that pair with your care and ship straight to your door through our secure Fullscript store. For shockwave patients, the Shockwave & Soft Tissue Healing package is built to support collagen synthesis, circulation, and tissue remodeling. It includes:

• Designs for Health Whole Body Collagen

• Pure Encapsulations L-Arginine

The complete package is $228.95, and you save 10% with auto-refill. If your main issue is knees, shoulders, elbows, or the Achilles, the Joint & Tendon Support package ($170.96) pairs Thorne Glucosamine & Chondroitin, Thorne Vitamin C 500, Thorne Super EPA, and Designs for Health Whole Body Collagen. You can see every package on our Shop Supplements page.

Which conditions does this approach fit?

Pairing shockwave with tendon-support nutrition makes the most sense for:

• Plantar fasciitis and heel spurs
• Achilles and hip tendon pain
• Jumper’s knee (patellar tendinitis)
• Tennis elbow and golfer’s elbow
• Rotator cuff and calcific shoulder tendinitis

How many shockwave sessions will I need, and what does it cost?

Most patients see significant improvement after 6 sessions, each about 20 minutes and spaced about one week apart, with many noticing a real change by sessions 3 to 4. Shockwave at Adisi Health Center is simple cash-pay pricing, with HSA and FSA accepted:

• New patient evaluation: $249, a 45-minute visit with a full exam, health history review, and your first shockwave treatment
• 6-session protocol: $1,050 (about $175 per session, saves $150)
• Single session: $200 per treatment area

Full details are in how much does shockwave therapy cost in Hinsdale? For the fastest recovery, our wellness memberships are our most committed option for accelerated healing, letting you combine up to 4 therapies per visit, including shockwave, Class IV laser, EMTT, and TECAR.

Does diet matter too?

Yes. Supplements work best on top of a solid diet with enough protein and plenty of colorful fruits and vegetables. For more on eating to calm pain, read Eat to Heal: how an anti-inflammatory diet supports pain relief.

Is it safe to take supplements during treatment?

For most healthy adults, these nutrients are well tolerated, and no side effects were reported in the collagen peptide trial above. Still, check with Dr. Petzel or your physician before starting any supplement, especially if you:

• Take blood thinners or have a bleeding disorder (fish oil, curcumin, and bromelain may add to bleeding risk)
• Are pregnant or nursing
• Have kidney disease or a history of kidney stones
• Take prescription medications or have a chronic health condition

Shockwave itself isn’t right for everyone. It may not be a good fit if you are pregnant, have a bleeding disorder or take blood thinners, have an infection, open wound, or tumor in the treatment area, or have a pacemaker or other implanted device near the treatment site. If you’ve had a cortisone shot, you must wait at least 6 weeks after your last cortisone shot before starting shockwave. Dr. Petzel reviews your health history and examines you before any treatment, and we recommend avoiding high-impact activity for 24 to 48 hours after each session. Get checked promptly if you heard a pop, can’t bear weight, or have sudden swelling or weakness, since that can point to a tear that needs a different approach.

Frequently asked questions

What is the best supplement for tendon healing?
Collagen (or gelatin) paired with vitamin C has the most research behind it. Studies show it increases collagen production and, combined with exercise, can improve tendon size, stiffness, and function.

Does collagen actually help tendons?
Yes, when combined with loading. A 2026 review of 8 randomized trials found 15 to 30 g of collagen a day with vitamin C plus resistance training increased tendon size and stiffness, and a 2019 study found collagen peptides helped Achilles tendinopathy patients improve faster.

Can supplements help shockwave therapy work better?
In a randomized trial of people getting shockwave for insertional Achilles tendinopathy, those who also took a daily supplement with arginine, collagen, MSM, vitamin C, and bromelain had better function and lower pain at 6 months than those on placebo.

When should I take collagen for tendons?
In the gelatin study, people took vitamin C-enriched gelatin about one hour before a short bout of exercise, which doubled a marker of new collagen production. Ask Dr. Petzel how to time it around your home exercises.

Which Adisi supplement package is right for shockwave patients?
The Shockwave & Soft Tissue Healing package (collagen, vitamin C, bromelain, zinc, and L-arginine) is designed for shockwave patients. The Joint & Tendon Support package is another option for knee, shoulder, elbow, and Achilles pain.

Can supplements replace shockwave or exercise for tendinitis?
No. Every positive study combined supplements with active treatment or exercise. Supplements support healing, but the tendon still needs the right stimulus to rebuild.

How much does shockwave cost in Hinsdale?
At Adisi Health Center, a 6-session protocol is $1,050 and a single session is $200 per treatment area. The first visit is a $249 new patient evaluation that includes an exam and your first treatment. HSA and FSA are accepted.
