Bone
Calcium, with a chaperone.
Calcium on its own can wander. Here it travels with K2-MK7 — the nutrient that supports your body's normal direction of calcium toward bone tissue.

60 vegan capsules · 1 per day · K2-MK7 + calcium + D3 + Black Pepper
If you're thinking about long-term bone and heart health, calcium is only half the story. This is the pair that actually goes together: the calcium your bones want, and the K2-MK7 that helps direct it toward bone — supporting the structure you're building rather than leaving it to wander.
“The combination that finally made sense to me.”

A quieter system
Three ways the shift shows up.
Heart
Bone and heart, together.
K2-MK7 supports the activity of the proteins that help keep calcium headed toward your bones — part of supporting normal bone and cardiovascular health together.
Both
One capsule, not two shelves.
Most people end up buying calcium, D3 and K2 separately and forgetting half. We put all three into one daily capsule — plus Black Pepper to support absorption of D3 and K2.

What's inside
The label is the whole story.
Every ingredient, the form we use, the dose per serving, the mechanism that makes it relevant, and the peer-reviewed study that backs it.
210 mg per serving
Calcium (as Calcium Carbonate)
Form: 210 mg per capsule
An essential mineral foundational to bone-tissue maintenance and muscle contraction. Calcium Carbonate delivers a high elemental calcium percentage per unit weight, making it an efficient form for a single-capsule dose.
Proprietary blend
Vitamin D3 (Cholecalciferol)
Form: 125 mcg (5,000 IU) per capsule
Required for calcium absorption from the gut. Without adequate D3, supplemental calcium passes through largely unused. Also supports immune modulation and endothelial stability.
Vitamin D and the immune system · Journal of Investigative Medicine, 2011Proprietary blend
Vitamin K2 (mk-7)(as Menaquinone)
Form: 100 mcg menaquinone-7 per capsule
The longest-acting form of K2. Supports osteocalcin (a bone-building protein) and matrix-Gla-protein activity — part of the body's normal direction of calcium toward bone tissue.
Three-year low-dose menaquinone-7 supplementation helps decrease bone loss in healthy postmenopausal women · Osteoporosis International, 20135 mg per serving
Black Pepper Extract (piperine)
Piper nigrum
Form: 5 mg standardised black pepper fruit extract per capsule
A standardised piperine extract that inhibits intestinal breakdown and enhances bioavailability of co-administered fat-soluble nutrients. Particularly relevant for D3 and K2, which are both fat-soluble vitamins.

Three-year low-dose menaquinone-7 supplementation helps decrease bone loss in healthy postmenopausal women
MK-7 supplementation significantly improved bone-mineral-density markers over 3 years vs placebo in postmenopausal women.

Honest answers
Questions you actually asked
Why pair bone and heart?
K2-MK7 sits at the centre of both — it supports the body's normal direction of calcium toward bone. Splitting bone and heart into two separate supplements duplicates the cost without adding value.
Why MK-7 and not MK-4?
MK-7 has a longer half-life (~72 hours vs ~6 hours for MK-4) — meaning a once-daily dose maintains stable blood levels. The research base for MK-7 in bone and cardiovascular outcomes is also deeper.
What does the black pepper extract actually do?
It is a standardised black pepper extract (piperine). Both D3 and K2 are fat-soluble vitamins — the piperine helps slow intestinal breakdown and enhances absorption of the nutrients in the same capsule.
How quickly will I notice anything?
Bone-density and cardiovascular endpoints are not symptom-driven for most people. This is upstream support — the benefits show up in long-term labs and resilience, not in next-week subjective changes.
When should I take it?
20–30 minutes before a meal, or with a meal containing some fat. D3 and K2 are both fat-soluble — a little dietary fat supports their absorption.
Can I take it with my ashwagandha?
Yes — they don't conflict. Common foundational stack: ashwagandha for stress, Bone & Heart for the cardiovascular and skeletal baseline.
Do I still need this if I take a multivitamin?
Most multis include token amounts of K2 and D3. The doses here — 100 mcg K2-MK7 and 125 mcg (5,000 IU) D3 — are calibrated specifically for the bone-heart axis. Check your multi label and decide whether the overlap works for you.
Is it safe during pregnancy or breastfeeding?
Calcium and D3 are commonly used during pregnancy under physician guidance. Talk to your physician about the K2 dose before starting.
Will it interact with my medication?
K2 may interact with warfarin and other anticoagulants. If you take blood thinners, talk to your physician before starting.
What if it doesn't work for me?
Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the bottles back.
How fast does it ship?
From our US warehouse, USPS Ground typically arrives in 2–4 business days within the contiguous US.
