Support your wellness routine with Bone Support Strips, a convenient and easy-to-take oral supplement formulated with Vitamin D3 and Vitamin K2. These essential nutrients play complementary roles in helping to maintain normal calcium absorption and supporting the body's natural bone health processes.
Vitamin D3 and Vitamin K2 work together to support the body's natural calcium utilization and bone maintenance functions. These essential nutrients play complementary roles in helping to maintain healthy calcium metabolism and contribute to the support of strong bones and teeth.*
Each delicious raspberry-flavored strip dissolves quickly on your tongue for on-the-go support — no water or swallowing required. Simply place one strip on your tongue and allow it to dissolve as part of your daily self-care routine.
Why people keep re-ordering Bone Support
-
2000 IU D3 + 120 mcg K2 as MK-7 — the two cofactors that help your body use the calcium it already gets, at doses backed by co-supplementation research.
-
Dissolves in ~30 seconds under your tongue — no water, no swallowing a horse-pill softgel, no forgetting the second bottle.
-
Two nutrients, one strip — D3 and K2 are usually sold separately. XYNE puts them in one raspberry-flavored film so the routine actually happens.
-
Cheaper than losing bone mass on your GLP-1. $29.99 tin / 30 strips = about $1/day. If you're on Ozempic, Wegovy, Mounjaro or another GLP-1, ask your doctor about bone-mineral loss — it's real, and it moves fast.
-
Honest sourcing: D3 (cholecalciferol) is sourced from lanolin (sheep wool). This SKU is vegetarian, not vegan. If you need vegan D3, look for lichen-sourced D3 or D2.
-
Clean label: gluten-free, non-GMO, no fillers, sugar-free, cGMP-certified.
You didn't come here by accident.
Maybe a scan came back somewhere you weren't expecting. Maybe your mother just broke a hip. Maybe you've been taking a calcium pill for years and something in you is quietly asking whether any of it is actually being put to use.
Here's what I think is happening.
Most people are told bone health is a calcium problem, so they take calcium and stop there. But absorbed calcium doesn't automatically end up in bone. Two fat-soluble vitamins do most of the directing: vitamin D3 supports how well your body absorbs calcium in the first place, and vitamin K2 — as MK-7 — helps activate the proteins (matrix Gla protein, osteocalcin) that put calcium into the bone matrix and help keep it out of soft tissue. Plenty of calcium routines are missing that second half. That's not a personal failure. It's a gap nobody explained.
Here's what I made for that.
Bone Support is a sublingual film — vitamin D3 (cholecalciferol; this SKU is not vegan) and vitamin K2 as MK-7, the most bioavailable menaquinone, dissolving under your tongue in about 30 seconds. It's not more calcium. It's the two cofactors that help your body put the calcium you already get from food and supplements to work — and support normal bone maintenance as you age.
I built this for the woman who did everything she was told — the calcium, the milk, the walking — and still wants to know the rest of it is reaching her bones.
This isn't a substitute for anything your doctor may want you on. It's the D3 and K2-MK7 substrate your body uses no matter what else is happening. The format built for the woman who's decided to age on her own terms.

Straight answers to the things you're hesitating on
"Will I feel it day 1?"
Honestly, no. Bone-mineral effects build over weeks and months — you can't feel calcium being put into a bone matrix. What you may notice, if you keep at it, is what stops happening: the low-grade fatigue that comes with low D, the mood dips that follow low sun months. Consistency matters more than the first dose. Give it a season, not a morning.
"Is 2000 IU D3 too much?"
It's above the RDA (600–800 IU for most adults) but well below the Tolerable Upper Intake Level the NIH sets at 4000 IU/day. 2000 IU is the range most vitamin-D deficiency correction protocols land in, and it's what many clinicians recommend for adults who don't get consistent midday sun. If you have kidney issues, a history of hypercalcemia, or you're already taking calcium supplements, talk to your doctor about total daily D3 before adding this in.
"Why not just buy D3 + K2 separately?"
You can. Most people don't — or they buy one and never get around to the other. Two bottles is twice the forgetting, twice the shelf space, twice the "did I take that today?" XYNE puts both in one strip, at doses the co-supplementation research actually uses, in a format that takes 30 seconds. One strip, one habit, one place your D3 + K2 lives.
FAQ
Do XYNE strips actually bypass the stomach?
Sublingual strips dissolve under the tongue, where a mesh of capillaries lets small, fat-soluble molecules diffuse directly into circulation — skipping first-pass metabolism in the liver. Not every molecule in every strip is 100% sublingually absorbed (some gets swallowed with saliva and processed the normal way), but the sublingual route is why onset is measured in seconds instead of the 30–60 minutes a capsule takes to break down in the gut.
How fast does a Bone Support Strip dissolve?
About 30 seconds under the tongue. Raspberry flavor. No water needed, no swallowing required.
Why D3 + K2 together?
D3 supports how well your body absorbs calcium from food and supplements. K2 — as MK-7 — helps activate the proteins (osteocalcin, matrix Gla protein) that direct calcium into bone and away from soft tissue like arteries. Studies of co-supplementation suggest the pair supports normal bone maintenance better than either alone. Taking D3 on its own increases circulating calcium; adding K2 helps make sure that calcium has somewhere to go.
Is this vegan?
No. The D3 (cholecalciferol) in Bone Support is sourced from lanolin (sheep wool), which is standard for potent D3 and is the reason we can hit 2000 IU reliably. The SKU is labeled vegetarian, not vegan. If you need vegan D3, look for lichen-sourced D3 or D2 (ergocalciferol) — those are the two vegan-compatible options.
Can I take Bone Support with a multivitamin?
Add up your daily D3 across every source — multivitamin, standalone D3, fortified milk, sun exposure. The NIH Tolerable Upper Intake Level for D3 is 4000 IU/day for most adults. If your multivitamin already has 1000–2000 IU of D3, stacking it with a Bone Support strip may push you close to or over that ceiling. Either skip the multi's D3, space them across the day, or talk to your doctor about your target range.
Is this safe to take on a GLP-1 medication (Ozempic, Wegovy, Mounjaro)?
Yes — vitamin D3 and K2 have no known interaction with GLP-1 agonists. Worth knowing: rapid weight loss on GLP-1s is associated with bone-mineral density loss, and clinicians are increasingly monitoring bone health during treatment. Bone Support is a supplement, not a treatment for GLP-1-related bone loss — but the D3 + K2 substrate is what your body uses to maintain bone regardless of what's driving the weight change. Talk to your prescribing doctor about bone-mineral monitoring while you're on treatment.
