Frequently asked questions +
Why only take 3 times per week?
Vitamin D3 has a half-life of approximately 20 days. It accumulates in your body fat and is slowly released. By taking a higher dose 3 times per week, you maintain a more stable D3 level than with daily low doses. This is also more practical and reduces the chance you forget to take it.
Isn't 5000 IU vitamin D3 too much?
5000 IU every 3 days equals approximately 1665 IU per day — a safe dosage. Many functional doctors recommend 2000-4000 IU per day, depending on your blood values. Have your 25(OH)D level measured to determine your ideal dosage. Aim for 75-125 nmol/L.
Why MK-7 and not MK-4?
MK-7 has a half-life of 72 hours versus 1-2 hours for MK-4. This means MK-7 remains active longer in your system, making it more effective with dosing every few days. MK-4 would need to be taken multiple times daily for the same effect.
Can I combine this with my current supplements?
Yes, but watch the total D3 content of all your supplements. Ideal combinations:
Magnesium: Essential — activates the enzymes that convert D3 to its active form.
Zinc: Strengthens immune system together with D3 via cell receptors.
Omega-3: Enhances the anti-inflammatory effects of D3. One of the most evidence-based foundation stacks.
Smart combinations with products we don't sell
For optimal D3 function we also recommend (available from other suppliers):
Vitamin A (retinol): 3000-5000 IU/day — works together with D3 at cellular level. Especially important with limited animal products.
Boron: 3mg/day — helps keep D3 available longer and supports calcium-magnesium balance.
Probiotics: Healthy gut improves absorption of fat-soluble vitamins like D3 and K2.
When should I have my D3 level tested?
Have your 25(OH)D level measured before you start and after 2-3 months of use. Optimal values are between 75-125 nmol/L. Above 250 nmol/L can be harmful. The test is available from your GP or online labs and costs approximately €25-40.
Benefits
Supports bone strength*
Vitamin D3 contributes to the normal absorption of calcium and phosphorus, essential for strong bones and teeth.
Directs calcium to bones*
Vitamin K2 activates proteins that direct calcium to the right places — to bones and away from blood vessels.
Immune system support*
Vitamin D3 contributes to the normal function of the immune system, especially important during winter months.
Long-acting K2 form
MK-7 has a half-life of 72 hours compared to 1-2 hours for MK-4, keeping it active longer in your system.
Optimal absorption
MCT oil from coconut ensures better absorption of fat-soluble vitamins D3 and K2 in the body.
Convenient to use
Only 5 drops needed 3 times per week. One 20ml bottle provides approximately 80 servings — nearly 8 months supply.
Why D3 and K2 together?
Vitamin D3 increases calcium absorption in the intestines, but without K2 this calcium can end up in soft tissues. K2 activates osteocalcin (directs calcium to bones) and matrix-GLA-protein (prevents calcification of blood vessels).
This synergy is crucial: D3 ensures availability, K2 ensures proper destination of calcium.
Tip: Combine with magnesium — this activates the enzymes that convert D3 to its active form in your body.
