What it is
A bone-support blend that goes beyond calcium alone, pairing three calcium sources -- including lithothamnion, a mineralized red seaweed -- with vitamin D, magnesium, vitamin C, vitamin K2 (as menaquinone), and boron. It delivers roughly 500 mg of calcium and 400 IU of vitamin D per daily dose. The design reflects that bone is living tissue built from a collagen framework hardened with minerals, needing several cofactors working together.
Why the evidence supports it
The evidence base for bone is strongest not for calcium in isolation but for calcium working alongside its cofactors: combined calcium-and-vitamin-D research is tied to healthier bone maintenance, vitamin D governs how well calcium is absorbed, and studies comparing vitamin K2 to K1 favor K2 for directing calcium into bone. Magnesium and boron round out the mineral cast that bone-building cells actually draw on. That full-cast approach is the evidence-based way to support the cell's Build function in bone -- supplying the minerals and cofactor vitamins used to construct and maintain the tissue -- alongside weight-bearing movement and a mineral-rich diet. And bone is not inert scaffolding: it is living tissue that houses the marrow where immune cells are made, so bone health and immune health are quietly linked -- the zinc and copper immune tissue leans on (in Zinc + Copper and the oyster whole-food Desiccated Oyster) support both at once.
What it supports
- Supports healthy, strong bones
- Provides calcium alongside the vitamin D and K2 that direct it
- Supports normal mineral balance
- Complements weight-bearing movement and a mineral-rich diet
Which function it supports
Ties to the cell's Build function -- supplying the minerals and cofactor vitamins bone-building cells use to construct and maintain bone tissue.

via Magnesium · 828 studies, 450 in people
Cofactor for both vitamin D activation and PTH secretion.
What people often notice when this marker sits outside the usual range

- Potassiumemerging evidence
via Magnesium · 17 studies, 7 in people
What people often notice when this marker sits outside the usual range
Higher: Serum potassium is a SAFETY marker, tightly regulated -- the body defends the blood level even when dietary intake is low, so a normal serum value does not confirm good dietary intake.
Lower: A low serum potassium (hypokalaemia) can cause muscle cramps, weakness, fatigue, constipation and palpitations -- also a medical finding to address with a clinician.
- Potassiumemerging evidence
via Magnesium · 17 studies, 7 in people
What people often notice when this marker sits outside the usual range
Higher: Serum potassium is a tightly regulated SAFETY marker -- the body defends the blood level even when dietary intake is low, so a normal serum value does not confirm good dietary intake.

via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Lower: A low ratio suggests good insulin sensitivity -- the favourable direction.
- Fasting Insulinemerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: A high fasting insulin is one of the EARLIEST signals of insulin resistance -- insulin climbs to keep glucose normal for years before glucose itself rises.
Lower: A low fasting insulin, with a normal glucose, generally reflects good insulin sensitivity -- the favourable direction.
- Fasting Glucoseemerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: A high fasting glucose is often silent early -- the classic high-sugar symptoms (excess thirst, frequent urination, fatigue, blurred vision) tend to appear later and higher.
Lower: A genuinely low glucose (hypoglycaemia) can cause shakiness, sweating, irritability, hunger and lightheadedness -- but a low-normal fasting value in a healthy person is usually favourable.
- Fasting Insulinemerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: Must be drawn fasting to be interpretable, and read alongside glucose (as HOMA-IR), never in isolation.
Lower: A low fasting insulin, with a normal glucose, generally reflects good insulin sensitivity -- the favourable direction.
- HOMA-IR (calculated -- a derived value, not a measured one)emerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: Because it is built from fasting insulin, it carries that assay's variability -- interpret the trend on one lab, not an absolute number.

- Fasting Glucoseemerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: A high fasting glucose is often silent early -- the classic high-sugar symptoms (excess thirst, frequent urination, fatigue, blurred vision) tend to appear later and higher.

- Triglyceride : HDL Ratio (calculated -- a derived value)emerging evidence
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Lower: A low ratio suggests good insulin sensitivity -- the favourable direction.
via Magnesium · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: The TyG index is a calculated insulin-resistance marker built from fasting triglycerides and fasting glucose -- a derived number, not a felt symptom.
Lower: A lower TyG index (within a population) is the favourable direction -- the validating studies read it as higher-versus-lower, not against a fixed line.
- Thyroglobulin Antibodies (TgAb)emerging evidence

What people often notice when this marker sits outside the usual range
Higher: Often NONE for years. Antibodies commonly precede any change in TSH or in how someone feels by a long time -- which is the argument for measuring them early rather than waiting.
Lower: Negative antibodies are the desired result and carry no symptoms.

What people often notice when this marker sits outside the usual range
Higher: Often NONE for years -- antibodies commonly precede any change in TSH or in how someone feels by a long time.
Lower: Negative antibodies are the desired result.
- Thyroglobulin Antibodies (TgAb)emerging evidence
via Vitamin D · 6 studies, 3 in people
Meta-analyses show reduced antibody titres, especially in those starting out deficient.
What people often notice when this marker sits outside the usual range
Higher: Same picture as TPO antibodies -- frequently silent for years, then the hypothyroid symptoms appearing while TSH still reads normal.
Lower: Negative is the desired result.
- Thyroid Peroxidase (TPO) and Thyroglobulin (Tg) Antibodiesemerging evidence
via Vitamin D · 6 studies, 3 in people
Meta-analyses show reduced antibody titres, especially in those starting out deficient [EMERGING].
What people often notice when this marker sits outside the usual range
Higher: In an autoimmune panel these are here because THYROID AUTOIMMUNITY IS THE COMMONEST AUTOIMMUNE CONDITION THERE IS, and it clusters with everything else on this panel.
Lower: Negative is the desired result.
- HbA1c (Hemoglobin A1c)emerging evidence
via Magnesium · 4 studies, 3 in people
What people often notice when this marker sits outside the usual range
Higher: A high HbA1c reflects the same chronic high-glucose state -- silent early, then thirst, frequent urination and fatigue at higher levels.
Lower: A low HbA1c is generally favourable, but an unexpectedly low value can reflect a red-cell condition rather than excellent control -- cross-check against fasting glucose if it surprises you.
- HbA1c (Glycated Hemoglobin)emerging evidence
via Magnesium · 4 studies, 3 in people
What people often notice when this marker sits outside the usual range
Higher: A high HbA1c reflects the same chronic high-glucose state as glucose, averaged over roughly three months -- silent early, then thirst, frequent urination and fatigue at higher levels.
Lower: A low HbA1c is generally favourable, but an unexpectedly low value can reflect a red-cell condition rather than excellent control -- cross-check against fasting glucose if it surprises you.
- eGFR, Creatinine & BUNemerging evidence
via Vitamin D · 7 studies, 2 in people
What people often notice when this marker sits outside the usual range
Higher: Later: swelling in ankles and around the eyes, foamy urine, fatigue, poor appetite, itching, night urination, high blood pressure.
Lower: A low creatinine usually reflects low muscle mass rather than excellent kidneys, and in older adults it can hide meaningfully reduced filtration.
- Leptinemerging evidence
via Vitamin D · 5 studies, 2 in people
What people often notice when this marker sits outside the usual range
Higher: Hunger that does not switch off after an adequate meal -- the signal is present but not being heard.
Lower: Persistent hunger, cold hands and feet, low mood and stalled menstrual cycles -- the low-energy-availability pattern seen in restrictive eating and in over-training.
- Thyroid-Stimulating Hormone (TSH)emerging evidence
via Vitamin D · 3 studies, 2 in people
What people often notice when this marker sits outside the usual range
Higher: Cold all the time, especially hands and feet, and needing more layers than everyone else in the room.
Lower: Racing or irregular heartbeat, palpitations, waking at night with the heart pounding.
- Urinalysis (Appearance, pH, Specific Gravity, Protein, Glucose, Ketones, Blood & Microscopic Findings)emerging evidence
via Vitamin D · 4 studies, 1 in people
What people often notice when this marker sits outside the usual range
Higher: KETONES: fasting, low-carbohydrate eating, or illness.
- Leademerging evidence
via Vitamin C · 3 studies, 1 in people
What people often notice when this marker sits outside the usual range
Higher: In adults, usually SILENT at the levels now common.
Lower: No symptoms. Lead has no biological function -- there is no deficiency, and lower is always better.
- hs-CRP (High-Sensitivity C-Reactive Protein)mixed evidence
via Vitamin D · 9 studies, 8 in people
What people often notice when this marker sits outside the usual range
Higher: A high hs-CRP reflects low-grade inflammation SOMEWHERE -- you tend to feel the underlying cause (a cold, a flare, a sore joint, poor sleep, extra weight) rather than the CRP itself.
Lower: A low hs-CRP is favourable and simply reflects little systemic inflammation at the moment of the draw.
- hs-CRP (High-Sensitivity C-Reactive Protein)mixed evidence
via Vitamin D · 9 studies, 8 in people
What people often notice when this marker sits outside the usual range
Higher: hs-CRP is non-specific -- read it as a trend and in context, never as a stand-alone verdict.
Lower: A low hs-CRP is favourable and simply reflects little systemic inflammation at the moment of the draw.
- Complement C3 and C4mixed evidence
via Vitamin D · 9 studies, 5 in people
What people often notice when this marker sits outside the usual range
Higher: C3 and C4 are acute-phase proteins and rise with ordinary inflammation and infection.
Lower: Persistently low complement with recurrent bacterial infections may instead indicate an inherited deficiency.

No product works in isolation
Every cell function above -- Sense, Exchange, Transform, Build, Maintain, Adapt -- needs the same broad base of optimal micronutrient levels running underneath it, all the time. Bone Formula is not a stand-alone fix; it is one piece that plugs into that larger system. The foundation comes first, and this supports it.
Stacks well with
Pick your goal -- here is what Bone Formula pairs with for each. Nothing works in isolation; these share the same systems.

For Minerals
For Women's Health
Foundational, or targeted?
Not everything in the shop is meant to be taken forever. Some products here are foundational -- a daily nutrient base built for long-term, ongoing use. Others are targeted -- shorter-term support for a specific season, not a lifelong habit. If you are not sure which one this is, that is a fair question to ask us before you buy.

Bone Formula is a bone-support blend providing calcium from mineralized seaweed and other sources, with vitamin D, magnesium, vitamin C, vitamin K2, and boron. It is built around the fuller set of nutrients bones use, not calcium alone. It fits people who want bone support that respects how bone actually works.
FAQ
What does Bone Formula support?
It supports healthy, strong bones, provides calcium alongside the vitamin D and K2 that direct it, supports normal mineral balance, and complements weight-bearing movement and a mineral-rich diet.
How do I take it?
Take the labeled daily servings with meals and water, ideally split across the day for absorption. The current bottle governs the real dose.
What makes it different?
It does not stop at calcium. Bone is living tissue that needs vitamin D, K2, magnesium, and boron working together, which is more sensible than a lone calcium pill.
