The Calcium Gap
Why Most Calcium Supplements Miss the Mark

Calcium is the most abundant mineral in the human body – over 99% stored in the skeleton. Every muscle contraction, nerve signal, and heartbeat draws from the same calcium reservoir that your bones depend on. When dietary intake falls short, the body borrows from bone to keep these functions running. That borrowing, compounded over years, is how bone density declines. The solution is not simply consuming more calcium – it is consuming calcium your body can actually absorb and direct correctly. 

Calcium carbonate – the standard cheap form – requires stomach acid to dissolve, making it significantly less effective in adults over 40 whose gastric acid production has naturally declined 

Most calcium supplements skip Vitamin D3, without which calcium cannot be transported from the gut into the bloodstream regardless of how much you consume 

Even fewer include Vitamin K27 – the critical co-factor that directs absorbed calcium into bone tissue rather than letting it circulate and potentially deposit in arteries and soft tissue 

Bone matrix formation also requires Manganese, Boron, and Selenium – trace minerals that most calcium supplements completely ignore, leaving the structural scaffolding incomplete 

The NatureFix Calcium Citrate Malate Difference
What's Inside Every Tablet
01
Calcium Citrate Malate

The clinically superior absorption form, acid-independent and effective at any age, taken with or without food

02
600 IU Vegetarian Vitamin D3 from Lichen

The only plant-sourced D3, identical in structure to skin-synthesised D3, activating calcium absorption in the gut lining 

03
Vitamin K27 (Menaquinone 0.5%, 55mcg)

Activates osteocalcin to bind calcium specifically to bone matrix, preventing soft tissue calcification 

04
Manganese (2mg, 50% RDA)

Manganese (2mg, 50% RDA), Selenium (40mcg, 100% RDA), and Boron Proteinate (150mcg) – the three co-minerals that complete the bone formation pathway 

Every Milligram Accounted For
What's Inside Every Tablet

Six ingredients, each with a documented role in the calcium absorption and bone metabolism pathway. Nothing for label appeal. Every milligram earns its place.

Calcium Citrate Malate
1250mg (300mg Elemental Calcium, 30% RDA)

The most bioavailable commercial calcium form. Calcium Citrate Malate is calcium bonded to citric and malic acids — a molecular structure that dissolves without requiring stomach acid. This matters significantly for adults over 40, whose gastric acid output has typically declined by 30–40%, and for anyone on proton pump inhibitors or antacids who cannot effectively break down calcium carbonate. Clinical absorption studies consistently show Citrate Malate outperforming Carbonate, particularly in fasted conditions. Each tablet delivers 300mg of elemental calcium — 30% of the adult RDA — providing a meaningful contribution without exceeding safe single-dose absorption limits. 

Vitamin D3
600 IU (Vegetarian, Lichen-Sourced, 100% RDA)

Vitamin D3 controls the production of calcium-binding proteins in the intestinal wall — without it, absorbed calcium cannot cross into the bloodstream regardless of dose. Most D3 supplements derive from lanolin, a sheep wool extract, making them unsuitable for vegetarians. NatureFix uses D3 extracted from Lichen — a plant-based organism that produces Cholecalciferol through photosynthesis — chemically identical to the D3 your skin makes from sunlight. 600 IU delivers 100% of the adult RDA, addressing the most common deficiency found in population studies, particularly in people with low sun exposure. 

Vitamin K27
(Menaquinone) 0.5% — 55mcg

Once calcium is absorbed into the bloodstream, K27 determines where it goes. Vitamin K2-7 activates a protein called osteocalcin – the molecule that physically binds calcium ions to the hydroxyapatite crystal structure of bone. Without adequate K27, absorbed calcium circulates freely, which over years is associated with arterial calcification and reduced bone mineralisation simultaneously. We use the 0.5% standardised Menaquinone form for consistent potency per tablet. At 55mcg, this provides meaningful K2 activity to support calcium’s correct deposition while remaining within safe supplementation levels for all healthy adults. 

Manganese · Selenium
Boron Proteinate

Three trace minerals that complete the bone formation system. Manganese (2mg, 50% RDA as Manganese Sulphate) is a cofactor for the enzymes that build glycosaminoglycans – the protein scaffold that calcium mineralises into in bone tissue. Without Manganese, the matrix on which bone mineral deposits is structurally compromised. Selenium (40mcg, 100% RDA as Sodium Selenite) protects osteoblasts – the bone-building cells – from the oxidative stress that would otherwise accelerate their programmed death and slow bone renewal. Boron Proteinate (150mcg) enhances the metabolism of calcium, magnesium, and Vitamin D, and has been shown to reduce urinary calcium excretion – meaning more of the calcium you absorb stays in the body rather than being lost.

Science-Backed Daily Performance
Six Reasons NatureFix Calcium Citrate Malate Outperforms Standard Calcium

Bone health is not a single-ingredient problem. The right calcium form, the right cofactors, and the right delivery mechanism all have to work together. These six advantages explain why this formula delivers outcomes that calcium carbonate alone cannot. 

Superior Calcium Absorption — With or Without Food

Calcium Citrate Malate absorbs effectively regardless of stomach acid levels – making it the only reliable calcium form for adults over 40, people with digestive conditions, and anyone taking antacids or acid-reducing medication. Clinical absorption studies show measurably higher plasma calcium levels after Citrate Malate versus Carbonate, particularly in fasted conditions. You get the 300mg of elemental calcium that is on the label – not a fraction of it filtered out by poor dissolution. 

100% Vegetarian Vitamin D3 from Lichen

Standard D3 supplements use lanolin from sheep wool. NatureFix uses Lichen-derived Cholecalciferol – the only certified plant-based D3 source – at 600 IU, delivering 100% of the adult RDA for Vitamin D. Without D3, calcium absorption from any source is dramatically reduced. With adequate D3, the intestinal transport proteins that move calcium into the bloodstream are fully activated, making every milligram of Calcium Citrate Malate work as intended. 

Vitamin K27 Directs Calcium Into Bone

K27 (Menaquinone) activates osteocalcin – the protein that specifically binds calcium to the bone mineral matrix. Without K27, absorbed calcium circulates and can deposit in arterial walls rather than bone. The 55mcg dose in each tablet uses the 0.5% standardised Menaquinone form, providing consistent K2 activity that persists in the body for days – ensuring calcium is continuously directed to the right destination as long as supplementation continues. 

Muscle Contraction & Nerve Signalling

Calcium is the mineral trigger of every muscle contraction in your body – from skeletal muscle during exercise to cardiac muscle with every heartbeat. It is also the primary ion that propagates nerve signals across synapses. Maintaining adequate calcium status through consistent supplementation supports the electrical and contractile function of the entire neuromuscular system – reducing cramping frequency and supporting the full range of physical performance. 

Manganese + Selenium + Boron Complete the System

Manganese builds the glycosaminoglycan scaffold that calcium mineralises into. Selenium protects bone-building cells from oxidative damage that would otherwise slow bone renewal. Boron reduces urinary calcium excretion so more of what you absorb is retained in the body. These three minerals work invisibly in the background of bone metabolism – but without them, the primary calcium-D3-K27 system operates at reduced efficiency. All three are present at meaningful doses sourced from bioavailable mineral forms. 

Long-Term Bone Density — A Lifetime Investment

Bone density peaks in the late twenties and declines from that point. The rate of decline is largely nutritional – determined by how consistently bone remodelling is supported with the right inputs. NatureFix Calcium Citrate Malate is designed for daily use as a long-term foundation supplement. The cumulative effect compounds over months and years of consistent supplementation. Starting earlier and staying consistent has a far greater impact on long-term skeletal health than any short-course intervention.

How to Use
Simple. One Tablet. Every Day..

No splitting doses across the day. No timing complexity. One tablet taken consistently provides your bones with the full mineral and cofactor supply they need for the long-term remodelling process. 

01
Take 1 Scoop Post-Workout

One tablet delivers your complete daily serving – 1250mg Calcium Citrate Malate providing 300mg elemental calcium (30% RDA), 600 IU Vegetarian Vitamin D3 from Lichen, 55mcg Vitamin K2-7, 2mg Manganese, 40mcg Selenium, and 150mcg Boron. Comprehensive bone nutrition in a single convenient tablet.

02
Mix With Water, Milk, or Anything

Calcium Citrate Malate is absorbed efficiently whether taken with food or on an empty stomach – however, consuming it with a meal that contains healthy fats can help optimize the absorption of Vitamins D3 and K2-7. Breakfast or dinner are both excellent options. Simply pair it with the meal you follow most consistently each day.

03
Time It Around Training

Bone health develops gradually over time — meaningful improvements in bone strength and mineral density require regular supplementation for several months rather than days or weeks. Many users report improved comfort and mobility within 4 to 8 weeks. Changes in bone density are typically observed after 6 months or longer.

Calcium Citrate Malate dissolves without stomach acid – making it significantly more effective in adults over 40, where gastric acid production naturally declines, and in anyone on antacids or proton pump inhibitors. Carbonate requires an acidic environment to dissolve and is used in most supplements because it is cheaper to produce – not because it is better absorbed. Clinical absorption studies consistently favour Citrate Malate, particularly when taken without food, which carbonate cannot effectively do. 

Vitamin K27 (Menaquinone) activates a bone protein called osteocalcin that physically binds calcium to the bone mineral matrix. Without K27, calcium absorbed through the action of Vitamin D3 circulates freely in the bloodstream and can deposit in arterial walls and soft tissue instead of being incorporated into bone. This is why calcium supplements taken without K2 have been associated in some studies with increased cardiovascular calcification over time. K27 turns calcium supplementation from a one-step process into a two-step system – absorb and direct. 

The earliest improvements are typically muscle cramp reduction and joint comfort – often noticeable within 4 to 6 weeks as calcium and D3 levels normalise in soft tissue and the nervous system. Meaningful bone density improvement is a 6 to 12 month outcome that requires consistent daily supplementation without gaps. Think of this as a long-term nutritional investment – the earlier you start and the more consistently you take it, the greater the lifetime skeletal benefit. 

Yes. The Vitamin D3 in NatureFix Calcium Citrate Malate is sourced exclusively from Lichen – a plant-based organism that produces Cholecalciferol through photosynthesis. It is chemically identical to lanolin-derived D3 and to the D3 your skin produces from sunlight, with the same bioactivity and absorption profile. It is the only certified vegan-suitable form of D3 available and makes this formula fully appropriate for vegetarians and vegans. 

Adults over 40 with declining stomach acid who struggle to absorb calcium carbonate. Postmenopausal women experiencing accelerated bone density loss. Vegetarians and vegans with low dairy intake and insufficient dietary calcium. People with limited sun exposure who are unable to maintain adequate D3 levels through sunlight. Anyone with a family history of osteoporosis looking to build a long-term nutritional foundation for bone health. Active individuals with higher calcium demands from muscle contraction and exercise. 

Yes. The Daily Multivitamin contains 25mg calcium and 10mcg (400 IU) Vitamin D2. Adding Calcium Citrate Malate brings total daily D to approximately 1000 IU – well within the established safe upper limit of 4000 IU for healthy adults. If you are also taking other D3 supplements, check the total combined dose with your healthcare provider. The Vitamin K27 in this formula is fully compatible with all other NatureFix products.
