Vitamin D3 + K2 Liquid Capsules

Why buy Vitamin D3-K2 capsules?

Many people take vitamin D3 on its own and overlook a crucial problem: D3 activates calcium absorption in the gut, but it does not control where the calcium goes in the body.¹ Without K2, calcium deposits in arteries and soft tissue instead of in the bones. Medical professionals call this the calcium paradox: your bones remain weak while your blood vessels harden.¹ ¹¹

Vitamin K2 takes over the steering: it transports calcium specifically into the bones while keeping it out of the arteries.¹⁰ Only this synergy makes supplementation safe and effective.¹ ³ Both vitamins work like a team: D3 supplies the raw material, K2 directs it to the right place.

If you want to build your performance long term, you need both. Single-ingredient products only do half the job.

What makes the vitamin D supply from GN Laboratories so special?

Most D3 and K2 products rely on powder capsules with average bioavailability. GN Laboratories takes a different path: liquid D3 in MCT oil combined with the branded raw material K2Vital® ensures that your body can utilize every microgram. No compromises on absorption, no losses from inferior formulations.

The numbers speak for themselves: studies show that fat-soluble vitamins in an oil base are absorbed up to 300 % better than in powder form.*

K2Vital® delivers the most stable form of menaquinone-7 on the market, with a 99.7 % all-trans structure.¹ ¹⁰

That means: every capsule works the way it should, without degradation from light or heat.

You're not getting a generic blend, but a well-thought-out formulation with scientifically validated raw materials. Developed for people who expect results.

MCT oil for maximum absorption

Vitamin D3 is fat-soluble and needs fat to be absorbed by the body. Many powder capsules rely on you eating something fatty at the same time. GN Laboratories solves this differently: MCT oil from coconut serves as a natural carrier medium and ensures that absorption works independently of your meal.

Scientifically confirmed: liquid formulations with MCT oil achieve up to 300 % higher bioavailability than dry powders.* Your body can utilize the sunshine vitamin directly, without depending on timing or fat intake. One capsule, full effect.

K2Vital® for verified stability

Not every form of K2 is equally effective. Many cheap products contain synthetic forms that lose their activity under light and heat. K2Vital® relies on menaquinone-7 in the biologically active all-trans form: 99.7 % purity, clinically tested and patented.¹ ¹⁰

The all-trans value determines the effect. Only this structure can be fully used by your body. K2Vital® remains stable even after months and consistently delivers the full dose. This is confirmed by independent laboratory testing and makes this active ingredient the first choice for serious supplementation.

Each of the 90 capsules contains 200 µg of vitamin K2 in this premium form. No compromises, no degradation products.

How do D3 and K2 work together?

Both vitamins regulate calcium metabolism, but at different levels. D3 activates absorption in the gut, K2 coordinates distribution throughout the body.¹ ³ This division of labor makes the combination more efficient than single-ingredient products: more calcium reaches the bones, less ends up in tissues where it causes harm.¹ ¹⁰ ¹¹

The effect unfolds over weeks: your body builds up reserves, stabilizes its supply, and optimizes processes such as muscle function and immune defense.⁴ ⁵ ⁶ Especially in months with little sunlight, the difference between adequate and insufficient supply becomes apparent.⁷

Those who supplement regularly lay the foundation for long-term stability, not just in winter.

Immune function, bones, and muscles

The sunshine vitamin supports the normal function of the immune system⁵ ⁶ and contributes to the maintenance of normal bones.² ³ Menaquinone activates proteins that incorporate calcium specifically into the bone structure.¹ ¹⁰ Both nutrients promote muscle function and recovery after intense sessions.⁴
