Frequently Asked Questions
Do I need Vitamin K2 with Vitamin D3?
K2 helps direct calcium to bones where D3 aids absorption; combining D3 with MK‑7 K2 is a sensible choice for bone health, especially when taking calcium supplements. Talk to your clinician about dose and interactions if you take blood thinners.
Which form is better for travel — chews or capsules?
Individually wrapped chews are easiest for pocket and carry‑on use and avoid pills, while capsules are compact and lighter in bottle size. Choose based on whether you prioritize taste/convenience (chews) or high potency per capsule and minimal bulk (capsules).
Can I take high-dose D3 (5,000 IU) daily?
Many adults take 2,000–5,000 IU daily during low-sun months, but you should confirm with a healthcare provider and ideally check blood levels (25(OH)D) before long‑term high‑dose use to ensure safety and avoid excess.
