It's probably not arthritis. It's your tendons, and the cells that repair them are out of fuel.

Every step, every stair, every night on your side puts tiny tears in your tendons. Your body repairs them overnight, and that repair runs on a cellular fuel called NAD+. When the fuel runs low, the tears pile up faster than your cells can fix them, and that's the ache that keeps coming back.

Read more ⌄

By age 50 you have about half the NAD+ you had at 30, and it drops fastest when estrogen falls in menopause. That's why the ache showed up in your 40s or 50s, why it spread from one joint to the next, and why it started waking you at night.

It shows up wherever your tendons work hardest:

  • Can't sleep on your side? Usually the gluteal tendon in your hip.
  • Reaching overhead hurts? The rotator cuff.
  • Knees hurt on the stairs? The patellar tendon.
  • First steps in the morning feel like broken glass? The plantar fascia in your foot.

Cortisone, pain pills and rest are aimed at the flare-up. They quiet it for a few weeks while the tendon keeps starving underneath. That's why the shot wore off and the pain came back worse. It isn't just age. It's a fuel shortage, and a shortage can be fed.

Doctors often call it arthritis, bursitis or "just age," but most of that pain starts in the tendon. Tendinopathy is the slow breakdown of tendon tissue, and it usually shows up before arthritis does.

Tendons wear a little every day. Your body repairs them, mostly while you sleep, and that repair runs on NAD+. Starving cells can't make collagen, can't clear damage, and can't close the tiny tears, so the tendon gets weaker and the ache keeps coming back.

That's also why an X-ray can come back "normal." An X-ray shows bone. It doesn't show a worn tendon, so the real problem gets missed.

CelluNAD+ works differently than cortisone, pain pills and collagen powders. It doesn't cover the ache. It gives your cells back the fuel they use to repair the tendon.

If you want to read the research yourself, here are some of the studies behind it:

  • Gluteal tendinopathy as the main source of outer hip pain in women after menopause, Grimaldi & Fearon, Journal of Orthopaedic & Sports Physical Therapy, 2015
  • NAD+ falls with age in human tissue, Massudi et al., PLoS One, 2012
  • Nicotinamide riboside at 300mg, Conze et al., Scientific Reports, 2019

Take two droppers (2 ml) under your tongue once a day. Shake the bottle, hold it under your tongue for 30 seconds, then swallow. First thing in the morning works best, and you can drink coffee or eat right after.

What matters is consistency. Tendon repair takes time, so steady daily use is what builds results.

Here's what most customers report:

  • Weeks 1 to 2: The first steps out of bed get easier.
  • Weeks 3 to 4: Walking without the ache following you into the night.
  • Months 2 to 3: Sleeping on your side again.
  • Ongoing: Your body makes less NAD+ over time, so keep taking it to keep the repair going.

Score the ache from 0 to 10 when you get out of bed. Most customers see the number move before they notice it any other way.

One note: If you are pregnant, nursing, on blood thinners, or managing a medical condition, check with your doctor first.

  • Made in the USA Manufactured in a GMP-certified facility in the United States.

Where do you feel it?

Tap where it hurts.

  • Shoulder
  • Elbow
  • Hip
  • Knee
  • Foot

The sign

"Reaching overhead feels like your shoulder is ripping apart?"

What it is

Rotator cuff tendinopathy. Tiny tears your cells can't repair after menopause, so the tendon stiffens and scar tissue builds up.

The sign

"Pain in your elbow every time you grip, lift, or twist?"

What it is

Tennis elbow. Tiny tears in the forearm tendons that your cells no longer have the fuel to rebuild.

The sign

"Can't sleep on your side without your hip screaming?"

What it is

Gluteal tendinopathy. The tendon on the outside of your hip loses its nightly repair when cellular fuel drops, and lying on it is what wakes you up.

The sign

"Knees hurt when you bend or take the stairs?"

What it is

Patellar tendinopathy. The tendon from your kneecap to your shinbone is wearing faster than starving cells can repair it.

The sign

"First steps in the morning feel like walking on broken glass?"

What it is

9 times out of 10, it's plantar fasciitis, a tendinopathy of the foot. Overnight repair never finishes, so the first steps tear it open again.

Same cause everywhere: the cells that repair your tendons ran out of fuel.

Inside Your Tendon

Starving vs. refueled. The difference is everything.

The Science Behind CelluNAD+

1

The Tendon Wears Thin

Every step, stair and night on your side puts tiny tears in your tendons. Your body repairs them while you sleep, and that repair runs on a fuel called NAD+. By your 50s you have about half of it, and it drops fastest when estrogen falls. The tears pile up faster than your cells can fix them.

2

The CelluNAD+ Refuel

CelluNAD+ puts 300mg of NR, liposomal delivery, and the B vitamins that switch it on into two droppers under your tongue. It skips your stomach and reaches your cells in minutes.

3

The Tendon Repairs

With the fuel back, your cells go back to their night shift: making collagen, clearing damage and closing the tiny tears. The tendon gets stronger instead of weaker.

4

You Move Freely Again

Your body already knows how to fix a tendon. It just ran out of the energy to do it. Most customers report less ache by week 2, walking without it by week 4, and sleeping on their side again by week 8.

Your Transformation Timeline

What most customers report in their first 90 days.

Phase 1

WEEKS 1-2 | Refueling

Your cells start getting their fuel back. Most women notice the first steps out of bed get easier before anything else.

Phase 2

WEEKS 3-4 | Walking Again

This is when most women notice. You walk the dog, you do the stairs, and the ache doesn't follow you into the night.

Phase 3

MONTHS 2-3 | Back On Your Side

You sleep on your side again. The ache that used to wake you up at 3am is gone most nights.

Phase 4

MONTHS 4-6 | Moving Freely

You stop planning your day around your hips and knees. Your body makes less NAD+ with age, so keep taking it to keep the repair going.

Common Questions

Everything you need to know about your tendons, results timelines, and what to expect

What does CelluNAD+ actually do for my tendons?

CelluNAD+ is a cellular fuel restoration formula. It gives your cells back the NAD+ they lost after 50 so they can go back to the jobs they stopped doing:

  • Producing collagen for tendons and ligaments
  • Clearing the micro-damage every step puts into a tendon
  • Keeping the repair going overnight so you wake up looser, not stiffer
  • Releasing the protective bracing your body builds around a sore joint
  • Working on every aching joint at once, not just one
How is CelluNAD+ different from collagen powders and joint pills?

Collagen powders and joint pills deliver building materials. CelluNAD+ gives your cells the energy to use them.

Two problems with the pills and powders you already tried:

  • Up to 90% is destroyed by stomach acid before it reaches a single cell
  • Even what arrives just sits there, because starving cells can’t turn it into tendon

CelluNAD+ is liposomal drops held under the tongue, so it skips the stomach. And it restores the fuel, so the repair work actually happens.

How long before I notice a difference?

Every body is different, but many women notice easier mornings and better sleep within the first 2 to 4 weeks.

Tendon repair takes time, so we recommend a full 90 days, every day, first thing in the morning. That is why the 90-day protocol is the one we recommend, and why the guarantee covers all 90 days.

Will CelluNAD+ work for me if I'm over 60?

Yes. CelluNAD+ was built for women 50+, including women in their 60s, 70s and beyond.

NAD+ keeps dropping with age, so the older you are the further your cells are from full fuel. Many of our happiest customers are women in the 55 to 75 range who had been told it was “just arthritis.”

What exactly is in CelluNAD+?

Every dose (2 ml) delivers clinical-range amounts, wrapped in liposomes:

  • Nicotinamide Riboside (NR) 300mg, the cellular fuel restorer
  • TA-65 astragalus extract 25mg, protects DNA during repair
  • CoQ10 50mg, restarts the cell’s power plants
  • Pterostilbene 50mg, antioxidant shield for repairing cells
  • TMG 50mg with vitamin B6, B12 and folate, switches the fuel on
  • Magnesium glycinate 50mg, muscle release and sleep support

Raspberry flavor, no artificial sweeteners, non-GMO, made in a GMP-certified facility and third-party tested by Eurofins in the USA.

Is CelluNAD+ non-GMO and free of artificial sweeteners?

Yes. CelluNAD+ is non-GMO and contains no artificial sweeteners. Every batch is third-party tested by Eurofins so an outside lab confirms the bottle has what the label says.

Can I take CelluNAD+ if I'm on medication, HRT, or blood thinners?

CelluNAD+ is drug-free and many women take it alongside HRT (HRT provides the signal, CelluNAD+ provides the fuel). As with anything new, please check with your healthcare provider first, especially if you are pregnant, nursing, on blood thinners, or managing a medical condition.

Is CelluNAD+ suitable for special diets? (vegetarian, halal, kosher)

CelluNAD+ contains no collagen, gelatin or animal-derived actives. Please check the full ingredient list on the label to confirm it fits your specific dietary needs (vegetarian, halal, kosher).

Does CelluNAD+ contain any allergens?

CelluNAD+ is free from milk, eggs, fish, shellfish, tree nuts, peanuts, wheat and sesame. The liposomes are made from lecithin, so please check the label if you have a soy or sunflower sensitivity.

Will CelluNAD+ cause any side effects?

CelluNAD+ uses clinical-range doses of ingredients studied in humans. Most women transition smoothly. A few notice a light flush or extra energy in the first days as NAD+ levels come back up, which settles quickly.

In the unlikely event you feel unwell, stop taking it and speak with your doctor. Let us know too; your safety comes first and your feedback helps us keep every batch right.
