How to Safely Boost Vitamin D: Case Study: From 7.5 to 47 ng/mL in 12 Weeks

At Qeliza Aesthetic Lounge, we recently helped a client raise their vitamin D levels from 7.5 ng/mL to 47 ng/mL in less than 3 months. Using a strategic, evidence-based protocol combining injectable and oral therapies, we achieved what most over-the-counter supplements can’t do alone.

The Qeliza Protocol

2 intramuscular injections of 300,000 IU of Vitamin D3, spaced 8 weeks apart
Daily oral support (Mon–Fri):
- 10,000 IU of Vitamin D3
- 100 mcg of Vitamin K2 (MK-7)

Weekends off to provide gentle cycling and avoid oversaturation.

The Science Behind the Strategy

Research shows:

A single dose of 300,000 IU can raise serum 25(OH)D levels by 15–25 ng/mL within weeks, depending on baseline levels and individual metabolism (Ilahi et al., 2008, Romagnoli et al., 2008).
Daily supplementation of 10,000 IU is generally considered safe in deficient individuals when monitored, and raises levels more consistently than low doses (Heaney et al., 2003).

Vitamin K2: The Unsung Hero

Prevents vascular calcification
Guides calcium into bones and teeth
Enhances the safety of high-dose D therapy (Schurgers et al., 2007)

Why Qeliza’s Vitamin D Works When Others Don’t

Most store-bought vitamin D products:

Are low-dose (1,000–2,000 IU)—barely enough to maintain, let alone replete
Often lack Vitamin K2
Use low-bioavailability carriers or unstable formulations

At Qeliza:

We source injectable-grade cholecalciferol (D3) that meets strict pharmaceutical standards
Our oral D3+K2 is specially compounded, ensuring:
- Superior absorption
- Optimal synergy between D and K
- No fillers or oxidized oils

You won’t find this anywhere else in Tirana. This is regenerative health done right.
