Nanoemulsified D3K2 by Quicksilver Scientific

If your Vitamin D, 25-Hydroxy is in the lower part of the normal range, this vitamin D3 K2 is a practical maintenance dose. It suits darker‑skinned adults, indoor workers, consistent sunscreen users, and anyone at northern latitudes. People with higher body weight often need more than 2,500 IU of vitamin D3 for repletion. If your level is meaningfully low, correct it under clinician guidance first, then use a vitamin D3 K2 maintenance plan.

Cholecalciferol (vitamin D3) is the form your skin makes from sunlight and raises blood levels more reliably than D2. It boosts calcium absorption from the gut and lowers parathyroid hormone (the signal that pulls calcium from bone). Vitamin K2 as MK‑7 activates proteins that move calcium into bone and keep it out of artery walls by carboxylating matrix Gla‑protein (a calcium‑binding brake in vessels). The nanoemulsion improves absorption and allows hold‑in‑mouth delivery for fast uptake.

Use 1 pump by mouth 1–2 times daily on an empty stomach, hold 30–90 seconds, then swallow. This provides 2,500 IU vitamin D3 plus 90 mcg K2 MK‑7 per pump, which is a maintenance‑level intake for most adults. If you are correcting deficiency, higher short‑term dosing is typical with follow‑up labs. Recheck Vitamin D, 25‑Hydroxy after 8–12 weeks. If you feel queasy on an empty stomach, take it 10–15 minutes before a meal with some fat.

Skip K2 if you take warfarin (a vitamin K–antagonist blood thinner) unless your prescriber plans INR monitoring. Direct oral anticoagulants like apixaban or rivaroxaban are not vitamin K–dependent, but still discuss changes. Avoid high‑dose vitamin D3 K2 if you have a history of high calcium, recurrent kidney stones, sarcoidosis, or primary hyperparathyroidism. Orlistat and bile acid binders reduce fat‑soluble vitamin absorption, so separate dosing by several hours.
