Primabolics Vitamin D3 + K2 | Cholecalciferol 1000 IU + Vitamin K2 90mcg | 60 Capsules

Primabolics Vitamin D3 + K2 is a two-ingredient, synergistic vitamin combination delivering 1000 IU of Vitamin D3 (Cholecalciferol) and 90mcg of Vitamin K2 per vegetarian capsule — with zero fillers and zero additives. Vitamins D3 and K2 are fat-soluble vitamins that work in close biological partnership: Vitamin D3 supports calcium absorption and immune function, while Vitamin K2 directs calcium to where it belongs — into bones and teeth — and away from soft tissues and arterial walls. Together, they represent one of the most well-supported vitamin pairings in modern nutritional science. Australian owned and manufactured, with complete label transparency.

Why Primabolics Vitamin D3 + K2?

• 1000 IU Vitamin D3 (Cholecalciferol) Per Capsule: Vitamin D3 is the most bioavailable and biologically active form of supplemental Vitamin D — the same form produced by the skin upon sun exposure. 1000 IU is a widely used, evidence-supported daily maintenance dose for individuals with limited sun exposure.
• 90mcg Vitamin K2 Per Capsule: Vitamin K2 is the biologically active form of Vitamin K responsible for activating the proteins that regulate calcium distribution in the body — including osteocalcin (bone) and Matrix Gla Protein (arterial walls).
• D3 + K2 — The Essential Pairing: Vitamin D3 significantly increases calcium absorption from the gut. Vitamin K2 ensures that absorbed calcium is properly directed to mineralise bone and teeth, rather than accumulating in soft tissues. Taking D3 without K2 is widely considered suboptimal in modern nutritional practice.
• Supports Bone Mineral Density: The D3 + K2 combination is widely used to support healthy bone density, calcium metabolism, and skeletal integrity — particularly important for athletes, ageing individuals, and those with limited sun exposure.
• Immune System Support: Vitamin D3 plays a well-established role in modulating immune function, with Vitamin D receptors present on virtually every immune cell in the body.
• 60 Capsules — 60 Full Serves: One capsule per serve, providing a 60-day supply at the standard daily dose.
• Vegetarian Capsule Shell: Encapsulated in a vegetarian Hydroxypropyl Methylcellulose (HPMC) capsule — suitable for vegetarians.
• Zero Energy, Zero Macros: Zero protein, zero carbohydrates, zero fat, zero sugar, and zero sodium per serving.
• Australian Owned & Manufactured: Formulated and produced locally to the highest manufacturing standards, with complete label transparency.

About Vitamin D3 + K2

Vitamin D3 (Cholecalciferol) is the naturally occurring form of Vitamin D produced in the skin upon exposure to UVB radiation, and is the preferred supplemental form due to its superior ability to raise and sustain serum 25-hydroxyvitamin D levels compared to Vitamin D2 (ergocalciferol). Beyond its well-known role in calcium absorption and bone mineralisation, Vitamin D3 is involved in immune regulation, muscle function, mood regulation, and cellular differentiation. Vitamin D deficiency is highly prevalent in Australia despite its sunny climate, particularly among indoor workers, shift workers, and individuals who consistently use high-SPF sunscreen. Vitamin K2 (as MK-7 or MK-4) is the biologically active form of Vitamin K responsible for activating Vitamin K-dependent proteins outside the liver — most notably osteocalcin (which binds calcium into the bone matrix) and Matrix Gla Protein (MGP), which inhibits calcium deposition in arterial walls and soft tissues. The combination of D3 and K2 is considered best practice in vitamin D supplementation, as D3-driven increases in calcium absorption require K2 to ensure proper calcium utilisation and distribution.

Directions for Use

Take 1–2 capsules daily with water as part of a balanced diet and healthy lifestyle. Best taken with a meal containing dietary fat, as Vitamins D3 and K2 are fat-soluble and are best absorbed in the presence of dietary fat.

Allergen & Storage Information

Store in a cool, dry place out of direct sunlight below 30°C. Keep out of reach of children.

Warning: This product is not a sole source of nutrition and should be used in conjunction with a balanced diet and healthy lifestyle.
