GAT Sport Vitamin D3 + K2 is an advanced daily micro-nutrient complex formulated for athletes, gym-goers, and active Australiaers looking to fortify immune defence, support cardiovascular health, and maximise bone density. Combining high-potency Vitamin D3 (the "sunshine vitamin") with Vitamin K2 (as Menaquinone-7), this synergistic formula ensures optimal calcium absorption and directing throughout the body. Whether you spend long hours training indoors, experience reduced sun exposure during winter months, or want comprehensive structural support, GAT Sport Vitamin D3 + K2 delivers essential daily foundation health.

Key Benefits & Features

• Synergistic Bone Support: Pairs Vitamin D3 with Vitamin K2 to ensure calcium is absorbed efficiently and deposited straight into bone matrix.

• Elevated Immune Defence: Delivers high-potency Vitamin D3 to strengthen white blood cell activity and fight seasonal fatigue.

• Cardiovascular & Arterial Health: Vitamin K2 (MK-7) helps inhibit calcium calcification within blood vessel walls, keeping arteries flexible.

• Superior Bioavailability: Utilises the premium, highly absorbable D3 (cholecalciferol) and K2 (MK-7) forms for long-lasting biological activity.

• Clean & Convenient Capsule: Delivers an exact, clinically supported daily dose in an easy-to-swallow vegetable capsule with zero fillers.

How It Works

Vitamin D3 and Vitamin K2 work in close harmony to regulate systemic calcium homeostasis. While Vitamin D3 facilitates the intestinal absorption of dietary calcium into the bloodstream, it cannot control where that calcium ends up on its own. Without adequate Vitamin K2, circulating calcium can accumulate in soft tissues and arterial walls, leading to unwanted arterial stiffness rather than strong skeletal structure.

Vitamin K2 activates osteocalcin, a specialised protein that binds free calcium ions directly to the bone matrix, increasing bone mineral density and resilience against heavy lifting strain. Simultaneously, K2 activates Matrix GLA Protein (MGP), which prevents calcium from hardening inside blood vessels. Combined with D3's natural modulation of immune cells and mood balance, this pair provides critical physical resilience for hard-training athletes.

Recommended Use

Take 1 capsule daily with a meal containing dietary fats, or as directed by your healthcare professional. Ensure you consume the capsule with a glass of water to assist absorption.
