Why are Vitamin D3 and K2 taken together?

Vitamin D3 helps your body absorb calcium, but Vitamin K2 (specifically MK-7) is the "traffic controller" that ensures the calcium reaches your bones and teeth rather than building up in your arteries. They work in a perfect synergy for both bone and cardiovascular health.

What is K2VITAL® and why is it better?

K2VITAL® is a patented, highly stable form of Vitamin K2 MK-7. Most K2 supplements degrade quickly over time, but K2VITAL® is microencapsulated to ensure the potency stays at 100% until the very last capsule in the bottle.

Why is MCT Oil Powder included in the capsules?

Vitamin D3 and K2 are fat-soluble, meaning they require fat to be absorbed by your digestive system. By adding MCT (Medium Chain Triglyceride) oil powder directly into the capsule, we ensure maximum bioavailability even if you take it on an empty stomach.

How many capsules should I take daily?

The recommended serving is 1 capsule per day, ideally taken in the morning. One bottle contains a 60-day supply of high-strength support.

Is this product suitable for vegetarians?

Yes, our Vitamin D3 + K2VITAL complex is housed in a vegetable-based HPMC capsule and is suitable for vegetarians. Our Vitamin D3 is responsibly sourced from Vita-algae D.

Does this supplement contain any fillers or binders?

No. We pride ourselves on a "Clean Label" philosophy. This product contains no magnesium stearate, synthetic fillers, or artificial binders, just active ingredients.

When is the best time of year to take this?

While Vitamin D3 is beneficial year-round, it is especially critical during the autumn and winter months (October to March) when the UK sun isn't strong enough for your skin to synthesize its own Vitamin D.

Where is this product manufactured?

Like all Sport Supplies products, this supplement is manufactured in the UK in a GMP-certified facility to ensure the highest standards of safety, quality, and batch consistency.

Support your body’s foundation with our high-strength Vitamin D3 and K2 formula. While Vitamin D3 is essential for immune defense and calcium absorption, Vitamin K2 acts as the "GPS," ensuring that calcium reaches your bones and teeth rather than accumulating in your arteries. To maximize effectiveness, we’ve suspended these fat-soluble vitamins in MCT Oil, providing superior bioavailability so your body can absorb every drop of sunshine, regardless of your last meal. It’s a simple, once-a-day essential for skeletal strength, cardiovascular health, and year-round immune resilience.

Vitamin D3 (The "Sunshine Vitamin") Immune System Guard: Plays a critical role in activating the body’s immune defenses to help fight off seasonal threats.

Calcium Absorption: Vital for absorbing calcium from your diet; without D3, your body cannot effectively use the minerals you consume.

Mood & Energy: Supports healthy serotonin levels, helping to maintain a positive mood and combat fatigue during darker months.

Vitamin K2 (as MK-7) Bone Density: Activates osteocalcin, a protein that binds calcium to the bone matrix, keeping your skeleton strong and resilient.

Cardiovascular Health: Helps prevent "vascular calcification" by keeping calcium out of the soft tissues and arteries, promoting better blood flow.

Superior Form: We use the MK-7 variant, which stays active in the body longer than other forms of K2 for 24-hour protection.

MCT Oil (Medium Chain Triglycerides) Enhanced Bioavailability: Since D3 and K2 are fat-soluble, they require fat to be absorbed. MCT oil provides a healthy fat source that allows for immediate uptake into the bloodstream.

Easy Digestion: MCTs are easily processed by the liver, making this supplement gentle on the stomach compared to tablets.

Medium Chain Triglycerides (MCT) Oil Powder (70% C8), HPMC Capsules (HydroxyPropylMethylCellulose), Vitamin D3 (Cholecalciferol From Vita-algae D), K2Vital® Delta Powder. Allergen Info: For allergens, see ingredients in bold.

As a food supplement for adults, take 1 tablet per day, preferably at mealtime or as directed by your healthcare professional. Do not exceed the stated dose. Do not use if the seal is broke.

Benefits

The Benefits of Vitamin D3 & K2 Supplementation

Our supplement has been designed as a Synergistic "Perfect Pair" Formulation:
The Mechanism: Vitamin D3 enhances calcium absorption, but without K2, that calcium can deposit in arteries (calcification).
The Benefit: Vitamin K2 acts as a "traffic warden," directing the absorbed calcium away from your heart and arteries and into your bones and teeth where it belongs.

This product is a high-performance supplement designed for those who want a scientifically-backed, highly absorbable way to support both bone density and cardiovascular health simultaneously.

High Potency DosageThis "Super Strength" version typically delivers 4000 IU (75µg) of Vitamin D3 and 100µg of K2VITAL® per capsule. This is significantly higher than standard "high street" supplements, making it ideal for correcting deficiencies or for use during winter months when natural D3 production is low.
Enhanced Bioavailability with MCT Oil PowderVitamins D3 and K2 are fat-soluble, meaning they require fats to be absorbed by the body.
Built-in Absorption: By adding MCT (Medium Chain Triglyceride) Oil Powder directly into the capsule, the product ensures that the vitamins can be absorbed effectively even if you take them on an empty stomach or with a low-fat meal.
Efficiency: This removes the guesswork for the user and ensures a higher percentage of the active ingredients actually reach the bloodstream.
K2VITAL® (Premium K2 MK-7)Instead of generic Vitamin K2, this product uses K2VITAL®, which is considered the gold standard in the industry. K2 is notoriously unstable and often degrades on the shelf. K2VITAL® is a microencapsulated form (Delta) that remains stable and potent throughout the product's shelf life.
