Frequently Asked Questions
The dose is 10,000 IU. Isn’t that high?
Yes, 10,000 IU is a high-strength dose typically used for short-term correction of deficiency under guidance. It’s not meant for everyone daily long-term.
How do I know if I need this dose?
A simple blood test (25(OH)D) will show your vitamin D levels. If you’re deficient or very low, your practitioner may recommend a higher dose like 10,000 IU for a limited time.
Should I talk to my doctor before taking this?
Yes, as high doses should be used with medical or practitioner supervision, especially if you're on medications, pregnant, or have health conditions.
How long should I take 10,000 IU for?
Typically, high-dose vitamin D is used for 2–8 weeks to raise levels, followed by a maintenance dose (e.g. 1,000–4,000 IU daily). Always follow professional advice.
Is it safe to take this every day?
It can be temporary, when correcting low levels but long-term high dosing can lead to excess calcium in the blood (hypercalcaemia), which is why K2 is included to direct calcium safely.
What does the K2 (MK-7) do in this formula?
K2 works with D3 to ensure calcium is absorbed and used correctly into your bones and teeth, not your arteries. This makes high-dose D3 safer and more effective.
When should I take it?
With a main meal containing fat, such as breakfast or lunch as both D3 and K2 are fat-soluble and absorb better this way.
What are the common signs of low Vitamin D?
- Low mood or seasonal blues
- Fatigue
- Bone pain or weak muscles
- Frequent colds or slow recovery
- A blood test confirms it.
Can I take this if I already get sun?
It depends on your skin type, sun exposure, location, and season. Even in sunny climates, many people are still low, especially in winter or if using SPF daily.
