One ingredient can't fix a Three-part problem.

Joint anatomy — three systems: cartilage, connective tissue, bone strength

Three pathways — Glucosamine to cartilage, MSM to connective tissue, Calcium+K2+D3 to bone

BioPerine absorption — without vs with absorption enhancer

And everything you've tried only addresses one of them.

The Pain Reliever Trap

NSAIDs

Your ibuprofen is a short-term solution. It doesn't support long-term joint health. The moment it wears off, discomfort returns — because nothing has changed underneath.

The One-Trick Supplement

Big-Box Glucosamine

Your big-box glucosamine addresses one pathway with a commodity ingredient your body can barely absorb. The other two pathways? Ignored completely.

Zengility®. Three Pathways. One Formula.

Reclaim Your Mobility →

Seven ingredients. Every one pulling weight.

GreenGrown® Glucosamine · 250 mg

Cushions cartilage so bending and walking feel less like work — at a fraction of the dose commodity glucosamine needs to do the same job.

OptiMSM® · 1.5 g

Keeps connective tissue flexible, so you can move without that stiff, locked-up feeling.

Plant Calcium (Lithothamnion) · 200 mg

Feeds your bones the minerals they recognize, the way real food does.

Vitamin K2 (MK-7) · 120 mcg

Directs calcium where it belongs — into your bones, where it builds strength.

PhytoD3® · 20 mcg

Drives calcium absorption from the gut, so your body uses what you swallow instead of flushing it.

Promentum® Calcium Fructoborate · 216 mg

Supports joint comfort, so stiffness feels less present.

Enhanced absorption for the six other ingredients

BioPerine® · 10 mg

Boosts absorption of everything above, so every capsule delivers its full dose, not a fraction.

What Our Customers Say

starstarstarstarstar

"First off Calcium and D3-K2 are actually supplements I already take on a daily basis and having them in one capsule is really nice. Im an extremely active person who works a physical job and also works out six days a week. Although great for my overall health my joint health is worsening with age for a fact. So far I haven't noticed any stomach issues from taking this supplement, nor have I had any bad taste or after taste. The tablet itself is easy to swallow. For the amount you get the ingredients and the price, it's a really excellent value!"

"These are more complete than my last glucosamine supplements. The capsules are easy to take and don't have a bad odor or taste. I think these are a decent value, especially when you consider the potency of the glucosamine along with the other vitamins and calcium this includes. Will recommend and buy again."

"I like the blend that is included in this supplement. It contains all the things that I've been trying to include in my daily supplement regimen to help with my increasingly arthritic knee, back, and hip joints, and overall bone health. The capsules are of a decent size that makes them easy and convenient to swallow. I like the strength — the MSM is at 1.5 whole GRAMS. I find blend supplements like this to be effective for me and can generally feel improvement within a couple of weeks. I consider this a success."

How does it work?

Everyday life, from long walks and workouts to aging joints and stiffness, can take a toll on your bone strength and mobility. That’s why many people are looking to support long-term joint comfort and skeletal health. Zengility® is a dual-action bone & joint support formula designed to help you stay strong, flexible, and active at any stage of life.

Here’s what healthy bone & joint support may help with:

Improved joint comfort & mobility — movement feels easier and more natural
Stronger bones & bone density support for long-term skeletal strength with aging
Reduced stiffness & faster recovery after activity or long days

Why Choose Zengility®?

Zengility® isn’t just another supplement; it’s a comprehensive bone and joint formula designed for real results and fast relief.

Dual-Action Formula: Supports both joint comfort and bone strength in one advanced capsule for continued protection and long-term mobility.

Premium Branded Ingredients: Features clinically studied, highly bioavailable nutrients like GreenGrown®, Promentum™, OptiMSM™, and BioPerine® for maximum effectiveness.

Fast-Acting Joint Support: Clinical evidence shows Promentum™ may improve joint comfort and reduce stiffness after activities in as little as 7 days, so you can get back to your favorite movements faster.

Supports Bone Strength: Calcium from marine algae, Vitamin K2, and D3 work together to maintain strong bones and healthy mobility, because calcium alone isn’t enough.

Clean, Plant-Based Ingredients: Shellfish-free glucosamine, vegan D3, and high-purity MSM make Zengility® safe for most dietary preferences.

Enhanced Absorption: BioPerine® improves nutrient uptake, so your body gets more out of every capsule with no wasted spend.

Zengility® is the smart choice for anyone who wants strong bones, flexible joints, and lasting mobility — all in one scientifically backed, clean, and effective formula.

Why not just take calcium or glucosamine?

Calcium or Glucosamine without Vitamin D and K2 is like watering a garden without sunlight. You’re doing part of the job but not enough to produce results.

Most joint formulas rely on outdated ingredients, weak dosages, cheap fillers, and single-path solutions that only treat symptoms — not the real problem.

When will Zengility® start working for me?

Zengility® capsules are designed for daily use as part of your bone and joint health routine. Take consistently as directed for the best results and to fully support joint comfort and bone strength.

Week 1–2

First changes. Promentum™ begins supporting joint comfort. Many customers notice reduced stiffness after daily activities.

Week 4

Building momentum. Glucosamine and MSM are supporting cartilage and connective tissue. Movement starts feeling easier.

Month 2

Real results. The full formula is working across all three pathways. Most customers report meaningful improvement in comfort and mobility.

Month 3–4

Peak performance. Bone density support from Calcium, K2, and D3 is fully engaged.

Month 5–6

Long-term maintenance. Consistent daily use sustains the benefits. This is where subscribers see the most value.

Like most nutritional supplements, Zengility® works best when used regularly as part of an ongoing healthy lifestyle that includes balanced nutrition, regular activity, and movement you enjoy.

Is Zengility® safe to take with my current medications?

If you are currently taking medications, we recommend consulting your primary care physician before using Zengility®.

This is especially important if you are taking:

Warfarin or other vitamin K antagonists (VKA)
CYP3A4 or P-gp substrates (such as cyclosporine or statins)
Levothyroxine
Antibiotics
Bisphosphonates
Iron supplements

Your healthcare provider can help determine whether Zengility® is appropriate for your individual needs.

Can I cancel my subscription at any time?

Yes. There are no contracts or hidden fees. You can pause, skip, or cancel your subscription at any time through your account on zenprinciple.com or by contacting our support team directly.

Please note that returns are only accepted for orders shipped within the United States or Canada. At this time, we are unable to process returns for international orders.

To initiate a return, please contact us at info@zenprinciple.com, and our team will provide you with the appropriate return instructions and mailing address.

Each bottle contains a 30-day supply. The recommended serving size is four capsules daily.

For convenience, some customers choose to divide their serving — taking two capsules in the morning with breakfast and two in the evening with dinner.

Zengility® is intended for daily use. Consistency is key to achieving optimal results.

For best outcomes, we recommend incorporating Zengility® into a well-rounded lifestyle that includes balanced nutrition, regular physical activity, and consistent movement.

Traditional supplements use 1,500 mg because shellfish-derived glucosamine has poor bioavailability — most of what you swallow doesn’t make it to your joints. GreenGrown® is plant-fermented for higher bioavailability, and it’s working in formula with OptiMSM®, Promentum™, and BioPerine®, which complement and amplify its effect. The result is meaningful joint support at a fraction of the dose commodity glucosamine needs — without the shellfish allergens or unnecessary high dosing.

No. Zengility® is a targeted joint health supplement formulated specifically to support mobility and comfort. It is not a collagen peptide or bone broth product.

While Zen Principle offers collagen and gelatin products separately, Zengility® is a distinct formula designed with a different purpose.
