Withanly · Bone & Heart Support

4.7 · 178 reviews

Your bones and your heart
are arguing
over the same calcium.

60 vegan capsules · 2 per day · K2-MK7 + magnesium + calcium + D3

Your doctor mentioned the calcium scoring number, or your last DEXA scan threw up a flag — and the next morning you stood in the supplement aisle looking at twelve different bottles. This is the pair that actually goes together: the calcium your bones want, and the K2 that tells it where to go so it doesn't end up where it shouldn't.

The combination that finally made sense to me.

The formula

Six things to know about what's in the bottle.

  • Organic ashwagandha root, 650mg
  • Black pepper for absorption
  • Vegan pullulan capsule
  • Third-party tested
  • No fillers or flow agents
  • Bottled in the USA, GMP-certified

A quieter system

Three ways the shift shows up.

The DEXA flag, addressed.

Bone

The DEXA flag, addressed.

Calcium without a chaperone wanders. Here it travels with K2 — the nutrient that actually walks it to the bone tissue your scan said it was missing.

For the cardiologist conversation.

Heart

For the cardiologist conversation.

If your last visit included the words 'calcium scoring' or 'plaque', this is the supplement built for that exact talk — including the CoQ10 that natural levels drop on after 40.

One bottle, not two shelves.

Both

One bottle, not two shelves.

Most people end up buying calcium, magnesium, D3, K2 and CoQ10 separately and forgetting half. We put the five your doctor actually mentions into one daily pair.

The whole ritual.

Take with breakfast & dinner

One capsule, twice a day, with water. No timing dance, no stimulant cycling.

Calm builds quietly

Most people notice a steadier daytime baseline within 7–10 days — not a hit, a settling.

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.

Magnesium (Magnesium Bisglycinate)

Form: 200 mg elemental magnesium from magnesium bisglycinate (per 2-cap serving)

Essential for over 300 enzymatic reactions, including those involved in bone-mineral formation and cardiovascular function. Bisglycinate is the gentlest form on the digestive system.

The main cause of shin splints is tight calves. Think of shin muscles and calf muscles as pulling on your feet in opposite directions. You have to use your shin muscles to pull your feet up off the ground to run....they work against your calves which pull them down, If your calves are tight, your shin muscles are having to work too hard and that causes pain and soreness. Regular calf stretches before and after working out should help greatly, It seems counterintuitive to stretch the opposite muscle, but this is what worked for me several times when I’ve had shin splints

Given your age, he's not wrong. I was diagnosed with severe osteoporosis at 70, so the anabolics followed by Prolia were a no-brainer. But you're 15 years younger than I am, so if you can take the bisphosphonates now and the anabolics later as needed, that's not a bad way to go. also, have you had any fractures? That's another tell for needing to go on the anabolics.

I had an initial endo appointment 5 months ago… she did not even know what Vitamin K was. She wanted me to start Alendronate. I also went to a rheumatologist who said I should start eating different fruits and vegetables and take my time starting osteo meds. Im still looking around for specialists who are more knowledgeable and have more experience in osteoporosis management.

My bone specialist said to try to get the 1200 mg calcium target through a combination of calcium citrate supplement and food where at least 50% of that 1200 mg should be from food.

I would get horrible shin splints years ago, what helped me was strengthening my calves and changing my gait. I used to walk and run heel/toe, I worked on more of a mid to forefoot strike while running and almost a flat foot while walking. My wife made fun of me saying I looked like a princess mincing while I walked. But hey, no pain for years, it also helped my knees too.

I've been taking magnesium for a few years after realizing I was deficient in it. My step-sisters take it to help slow their minds so they can sleep. I take it in powder form in the morning and in the afternoon. It doesn't have a sleepy effect for me, but helps my brain remain calm, plus it helps me with inflammation and swelling. I'm glad it's working for you!

I agree, magnesium glycinate in the evening is my must. A few weeks agod I've added also 20mg of Zinc (zinc picolinate from [brand removed]) to my evening mix and it's even better! I monitore my sleep with Garmin Watch so actually I'm motivated also with these data haha.

The amount of people that are magnesium and vitamin d deficient is insane. Most people go on these crazy cycles of prescribed drugs and end up worse than they were before. I wonder how mental health in general would be if everyone’s levels of both were right and alcohol was no longer a thought. I’m pretty sure the results would be drastic (in a good way) Get your blood work done for vitamin d (magnesium blood work isn’t worth a damn sadly). 1000iu really isn’t much if you’re deficient. Then look into the [Vitamin D Protocol ](http://www.vitamindprotocol.com)

Well, if you were deficient in magnesium or vit d or both, your symptoms would be depression and low energy respectively, and supplementing them would resolve your symptoms. The glycine is also beneficial in treating restlessness and attention deficit (it can also make you sleepy). Its amazing how quick psychiatrists are to jump to prescriptions in the midst of deficiencies and cleaner, simpler solutions.

Honest answers

Questions you actually asked

Why pair bone and heart?

K2-MK7 sits at the centre of both. It directs calcium into bone (where you want it) and away from arteries (where you don't). Splitting bone and heart into two 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 daily dose maintains stable blood levels. The research base for MK-7 in bone and cardiovascular outcomes is also deeper.

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?

With a meal containing some fat — D3 and K2 are both fat-soluble.

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 have only 90 mcg K2-MK7 and 1,000 IU D3 — meaningful but not necessarily optimal. The doses here are calibrated for the bone-heart axis specifically. If you're on a multi, you may not need both.

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 directly interacts with warfarin. If you take warfarin or other 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.
