Optimal D3 + K2 Complex 5000 IU

Most people are deficient in Vitamin D3. Almost no one gets enough K2. Together, they are one of the most important nutritional partnerships in the body  and one of the most commonly overlooked. The Optimal D3 + K2 Complex was formulated by Dr. Cris to close that gap, cleanly and effectively.

At Dr. Cris Studio, we believe that no aesthetic treatment  no injectable, no thread, no laser  can outperform a body that is nutritionally depleted. Supplements are not optional extras. They are the foundation. And D3 + K2 is one of the most foundational combinations we recommend to every patient.

Why D3 and K2 must work together

Here's what most people don't know: taking Vitamin D3 alone increases calcium absorption but without K2, that calcium can end up in the wrong places. Arteries. Soft tissue. Not bones.

Vitamin K2 (as MK-7, the most bioavailable form) acts as the traffic director  it activates proteins that shuttle calcium away from arteries and into bones and teeth, where it belongs. The result is a supplement that supports bone density and cardiovascular health simultaneously, rather than trading one for the other.

What it does

• Bone density & fracture prevention — D3 drives calcium absorption; K2 MK-7 directs it to bones and teeth, supporting long-term skeletal strength
• Heart & arterial health — K2 prevents calcium from depositing in arterial walls, supporting healthy circulation and cardiovascular function
• Immune function — D3 is essential for a well-regulated immune response; deficiency is linked to increased susceptibility to infection and inflammation
• Mood & mental health — D3 plays a key role in serotonin synthesis and mood regulation; low D3 is strongly associated with depression and seasonal mood changes
• Muscle health — D3 supports muscle function and reduces the risk of weakness and falls, particularly important as we age
• Dental health — the D3/K2 combination supports the mineralization of teeth alongside bones

Why 5000 IU?

The standard 400–1000 IU found in most multivitamins is rarely sufficient to correct deficiency especially in people who spend most of their time indoors, live in northern climates, or have darker skin tones. 5000 IU is the dose most commonly used in clinical practice to restore and maintain optimal D3 levels. Always consult your healthcare provider to confirm the right dose for your individual levels.
