A bone formula built as a system: plant-based calcium from marine algae, with magnesium, vitamin D3, vitamin K2, vitamin C and potassium. Calcium, vitamin D, vitamin K and magnesium all contribute to the maintenance of normal bones; 120 capsules, a one-month supply.
- Calcium from marine algae
- D3, K2, magnesium, C
- Bone maintenance claims
- 120 capsules, one month
-
Calcium from marine algae. Plant-based rather than quarried, calcium is needed for the maintenance of normal bones*.
-
The rest of the bone team. Vitamin D, vitamin K and magnesium each contribute to the maintenance of normal bones* too.
-
Muscle, the working partner. Vitamin D contributes to the maintenance of normal muscle function and magnesium contributes to normal muscle function*.
-
Collagen's supporting nutrient. Vitamin C contributes to normal collagen formation for the normal function of bones*.
The team, not the mineral. Here's the thinking.
First, check what you're already taking.
If you take a multivitamin, read its label before adding this one: many already carry calcium, vitamin D, K2 or magnesium.
This product is maintenance, not repair: anyone with a diagnosed bone condition should be guided by their doctor, with this as a food supplement alongside, never instead.
Why this formula
The rest of "first, check what you're already taking":
Add the amounts together, and if the totals look high, choose one product rather than stacking both. A tidy routine beats an accumulating one, even when the second bottle is ours.
Why more nutrients than calcium?
Because bone isn't maintained by calcium alone. Vitamin D, vitamin K and magnesium each hold the same authorised bone- maintenance claim calcium does, and vitamin C contributes to normal collagen formation for the normal function of bones. A calcium-only product answers one line of a team sheet.
Who is this NOT for?
If your multivitamin already covers these nutrients at meaningful levels, you may not need a separate bone formula at all. This product suits people making bone nutrition a deliberate, long-term line in their routine, often in mid-life and beyond.
Benefit highlights, in full
(unedited field 4, kept for the accordion): - Calcium from marine algae. Plant-based rather than quarried, and doing the headline job: calcium is needed for the maintenance of normal bones*. The source is the difference you can read on the label. - The rest of the bone team. Vitamin D, vitamin K and magnesium each contribute to the maintenance of normal bones* too. Bone is maintained by a group of nutrients working together, which is why this is a formula and not a calcium tablet. - Muscle, the working partner. Vitamin D contributes to the maintenance of normal muscle function and magnesium contributes to normal muscle function*. Bones don't work alone, and neither does this formula. - Collagen's supporting nutrient. Vitamin C contributes to normal collagen formation for the normal function of bones*. Collagen is part of bone's structure, a fact most calcium products never mention. - A month of the routine. 120 capsules at the labelled daily serving. Bone maintenance is a long game; the pack is built for a steady monthly rhythm.

Questions
Why is the serving more than one capsule?
Minerals take up room. A meaningful amount of calcium plus magnesium physically cannot fit in one capsule, so the daily serving is four capsules. The label's own suggestion, two with breakfast and two with dinner, is the comfortable way to take them.
What's different about calcium from marine algae?
The source. It's harvested from algae rather than mined rock, and it arrives alongside the trace minerals the algae contain. The authorised claim is the same either way: calcium is needed for the maintenance of normal bones. The source is a sourcing choice you can see on the label.
Why is vitamin K2 in a bone product?
Because vitamin K contributes to the maintenance of normal bones, the same authorised claim calcium holds. The K2 here is the team-sheet logic of the formula: the nutrients with bone claims, together in one serving. If you take blood-thinning medication, speak to your doctor first.
Can I take it with my multivitamin?
Check the two labels side by side first. If your multivitamin already contains calcium, D, K or magnesium, add the totals together before deciding. Sometimes the honest answer is that you only need one of the two products.
How do I know what's in it?
The nutrition table on this page is the label, transcribed: every nutrient, its form, the amount and the %NRV. Every bottle carries its batch number and best-before date.
How long should I take it for?
Bone maintenance is measured in years, not bottles. This is a routine product: a steady daily serving, kept up over the long term as part of a diet that also carries calcium. It is not a short course with a finish line.
What to expect
Days 1 to 14: Nothing to feel, and honestly you shouldn't expect to. Bone nutrition works silently and slowly. The job this fortnight is the habit: the labelled serving, split across meals you already eat.
Weeks 4 to 8: The routine is automatic and the bottle is nearly done; this is a one-month pack. What you're building doesn't announce itself, which is normal.
Ongoing: Maintenance is the whole product. Set a monthly reorder rhythm and let the years do the compounding.
Pack options
Two pack sizes, one formula: the whole bone team in every serving, whichever bottle it comes from. The daily serving is four capsules.

Our in-house nutrition tip
What I look for in a bone formula is the team sheet, because calcium was never meant to work alone. This one reads correctly: marine-algae calcium with magnesium, vitamin D3, vitamin K2 and vitamin C in the same serving, each earning its place with an authorised bone or muscle claim rather than padding. Before you buy it, do the one check I'd insist on: read your multivitamin's label and add the calcium and D together. And to be clear about what it is not: it can't stand in for dietary calcium, weight-bearing movement, or your doctor's advice on any diagnosed bone condition. It's the maintenance line, kept up over years.
