Bone Health Insider Independent review, Australia, updated 2026

I tested 10 bone supplements for my patients. Here's the truth.

Every one of them was trying to do the same single job. Your bones need 3.

The 10 bone supplements tested, on a Australia chemist shelf
All 10 products tested, every one of them sold in Australia today.

For 2 years my patients have been asking me the same question. They come in holding a DEXA scan that went the wrong way, they have taken their calcium faithfully the whole time, and they want to know which bottle to buy instead.

I did not have a good answer for them. Telling a woman to keep doing the thing that just failed her is not an answer.

So I bought 10 of the most recommended bone supplements in Australia and read every label myself. Not the marketing. The label.

What I found is that almost every one of them is answering a question nobody asked. Here is what is actually on those labels, and what it means for the scan you are holding.

Your bones need a signal to build, material to build with, and a lock to hold the new bone in. Every product in this category sells you material. That is 1 job out of 3.

What I judged them on

Three jobs. Every product got marked on all 3.

1

THE SIGNAL

What tells bone to rebuild is oestrogen. At menopause that instruction goes quiet, and no amount of extra material brings it back.

2

THE MATERIAL

Once the signal is on, bone needs something to build with. The chalk calcium in most bottles is ground limestone, and it washes straight through you.

3

THE LOCK

Brand new bone starts out soft. If it does not harden, it breaks as easily as the old bone did.

The rankings

RANKED FIRST, EDITOR'S PICK

Optimum Shilajit Bone Restore Trifecta

One bottle. 90 capsules. 3 a day.

This is the only one on the list I have watched move a number. Not hold it steady. Move it.

It is the only thing I found that does all 3 jobs, and each part has its own trial behind it.

1. THE SIGNAL  ·  SHILAJIT

  1. Turns your body's own oestrogen signal back on, so your bones are told to build again.
  2. Women past menopause with osteoporosis. Every single one who took it built her bone density back. The placebo group kept losing.

2. THE MATERIAL  ·  PEARL

  1. Calcium arranged the way your own bone arranges it, so your body can actually build with it. Surgeons use it for bone grafts.
  2. Postmenopausal women, given pearl. Their osteoporosis reversed. Not slowed. Reversed.

3. THE LOCK  ·  BAMBOO SILICA

  1. Hardens the new bone and locks it to the frame, so your bone bends instead of breaking.
  2. In nearly 3,000 people, the ones with the most silicon had hip bone density 10% higher than the ones with the least.

The signal, the material, and the lock. Everything else on this list was doing 1 of those jobs at best.

All 3 ingredients independent third party lab tested for heavy metals and mould, results posted where you can read them. A small family owned company, run by people who actually answer the phone. And in every study ever done on it, not one serious side effect.

It is safe even with breast cancer in the family, because it is not a hormone and does not feed anything. They tested it right on the breast cancer cells that feed on oestrogen, and it killed those cells and left the healthy ones alone.

They stand behind it for 6 months, because 6 months is how long it took the women in that trial to turn their bone around. They give you the very same window the study did.

THE VERDICT

The only product here that does all 3 jobs instead of 1. If your scan is going the wrong way, start here.

Ranked 2 to 10, best of the remainder first.

02

Ostelin Calcium & Vitamin D3

600mg calcium per tablet with 500IU D3, 2 tablets daily

Australia's default bone supplement, and it deserves the position. One tablet a day, a serious D3 dose, and a formula that does its job properly. The trouble is which job. It supplies material to a body that has stopped being told to use it, and nothing in it hardens the new bone once it is laid.

Ostelin Calcium & Vitamin D3

GETS RIGHT

  • Australia's most trusted bone brand
  • 1000IU of D3, a serious dose
  • Only 1 tablet a day
  • Well made

FALLS SHORT

  • Nothing that addresses the signal
  • No lock, so new bone stays soft
  • Material only, 1 job of 3

The best-executed single job on this shelf.

03

Ostelin Vitamin D3 & K2

1000IU D3 with 180mcg K2, and no calcium in it at all

The K2 is a genuinely good addition, because K2 helps direct calcium toward bone rather than arteries. It is the closest thing on this shelf to a second job. But directing calcium is not the same as switching the signal back on, and there is still nothing that hardens new bone.

Ostelin Vitamin D3 & K2

GETS RIGHT

  • K2 at 180mcg, a real dose
  • Helps direct calcium toward bone
  • 1 tablet daily

FALLS SHORT

  • Nothing that addresses the signal
  • The K2 is real, but it works one step downstream, so the lock has nothing to hold
  • No calcium in it at all

The nearest miss on this shelf.

04

Blackmores Total Calcium Magnesium + D3

229mg calcium a tablet, with magnesium, zinc, D3 and vitamin K1

A trusted Australian name and a sensible formula. It is doing the same thing every other bottle here is doing, which is handing your bones material and hoping the body knows what to do with it.

Blackmores Total Calcium Magnesium + D3

GETS RIGHT

  • Long-trusted Australian brand
  • Sensible co-factors
  • Widely stocked

FALLS SHORT

  • Nothing that addresses the signal
  • The one lock-looking vitamin on the label is K1, the clotting one, not K2
  • Material only

Trusted brand, single job.

Nine of these do 1 job. One does all 3.

I did not think anything would help after watching my scores fall year after year, so when the doctor told me my spine had come up from a −2.6 to a −2.1 I made her repeat it twice. I sat out in the parking lot and cried a little before I drove home.

Two years of Prolia and my spine barely held. One year on this and I moved from −2.7 to −2.2. I was the skeptical one, not anymore.

Sandra M. · May 21, 2026 · Verified buyer

I had surgery done on my foot, due to severe arthritis. While taking this mineral, my foot healed faster than normal with new bone growth right where it was needed. At 72 years old, that’s a huge difference! Now I’m back in shoes and walking around in less than six weeks.

Spine −2.6 to −2.2 in ten months. Hip held steady instead of dropping. Thats the report, thats why I reorder.

Kathleen S. · June 25, 2026 · Verified buyer

What originally convinced me to try Shilajit is that it’s been studied to improve bone density. I am happy to report that some of my bone density markers (t-scores) have significantly improved as of my test last week and that my arms are no longer in the osteopenic range.

My mother broke her hip at 68 and never really walked right again, so a −2.8 spine reading terrified me. Latest scan came back −2.3. I am not passing her story down to my daughter if I can help it.

Left exactly as they were written, which is why the American spellings are still in them. The rating breakdown is every published review, not only the ones shown here.

What I tell my patients now

If you have already taken calcium for years and watched your DEXA scan get worse anyway, that is not you failing at it. That is the strategy failing you.

Your bones need 3 things. A signal telling them to build, material to build with, and a lock to hold the new bone in place. Nine of the 10 products on this list do exactly one of those, and they all do the same one.

One product here does all 3, and each of its 3 parts has a trial of its own behind it.

If your scan is going the wrong way, that is where I would have you start.
