why we made this

Over 40% of American adults are deficient in vitamin D… and almost none of them are getting adequate vitamin K2. Without K2, calcium doesn’t reach your bones. Instead, it accumulates in your arteries and soft tissues where it causes real damage. Dynamic D-K2 solves both problems with a single capsule: clinical-strength D3 to boost calcium absorption plus MenaQ7® PRO K2 to direct that calcium exactly where it belongs… into your bones, not your blood vessels.

Two Essential Vitamins.One Synergistic Formula.Complete Bone & Heart Defense.

Most D3 supplements ignore a critical partner: vitamin K2. Without K2, the calcium D3 helps you absorb has no guidance system… it ends up calcifying arteries instead of strengthening bones. Dynamic D-K2 pairs clinical-strength D3 with the most researched form of K2 on the planet for complete calcium optimization.

Vitamin D3 (Cholecalciferol) - 5,000 IU

The body’s master regulator for calcium absorption, immune defense, and mood. D3 is the most bioavailable form of vitamin D… identical to what your skin produces from sunlight. At 5,000 IU, this dose corrects deficiency and maintains optimal blood levels year-round.

Vitamin K2 (MenaQ7® PRO, MK-7) - 45 mcg

The most clinically studied form of vitamin K2, backed by 15+ clinical trials at the University of Maastricht. K2 activates osteocalcin (which binds calcium to bone) and matrix Gla protein (which prevents arterial calcification). MenaQ7® PRO has the longest half-life of any K2 form, providing 24-hour protection in a single dose.

Vitamin D3 (Cholecalciferol)

Vitamin D3 is a fat-soluble vitamin essential for calcium and phosphorus absorption, bone mineralization, immune regulation, and mood support. Unlike D2 (ergocalciferol), D3 is the form naturally produced by your body and is significantly more effective at raising and maintaining blood levels. Deficiency is linked to osteoporosis, weakened immunity, fatigue, depression, and increased cardiovascular risk. At 5,000 IU (125 mcg), Dynamic D-K2 delivers a clinical-strength dose that corrects deficiency within weeks and sustains optimal 25(OH)D levels year-round… especially critical for those who spend limited time in direct sunlight, live in northern climates, or have darker skin tones.

Vitamin K2 (MenaQ7® PRO, Menaquinone-7)

MenaQ7® PRO is the world’s most clinically validated vitamin K2 as MK-7, developed through over 15 clinical trials led by Dr. Leon Schurgers at the University of Maastricht. Vitamin K2 serves as calcium’s traffic director: it activates osteocalcin, the protein that binds calcium into the bone matrix, and simultaneously activates matrix Gla protein (MGP), which prevents calcium from depositing in arterial walls and soft tissues. The MK-7 form has a uniquely long half-life compared to MK-4, providing consistent 24-hour vascular and skeletal protection from a single daily dose. Research shows K2 supplementation decreases osteoclast activity (cells that break down bone), maintaining bone mineral density while providing critical cardiovascular protection against calcification.

Dynamic D-K2 has helped thousands of patients optimize their vitamin D levels, strengthen bones, and protect cardiovascular health.

MY VITAMIN D FINALLY STAYED UP

I’ve been chronically low in vitamin D for years. Other supplements barely moved my levels. Within 60 days on Dynamic D-K2, my bloodwork showed optimal D levels for the first time; and my doctor said my calcium was going to the right places. The K2 makes all the difference.

STRONGER BONES AT 58

After my DEXA scan showed early osteopenia, I started Dynamic D-K2 alongside my calcium supplement. My follow-up scan 12 months later showed improved bone density. My orthopedic doctor was genuinely surprised. I’m a believer.

ENERGY I HADN’T FELT IN YEARS

I didn’t realize how much vitamin D deficiency was affecting me until I started this supplement. Within three weeks, my energy came back, my mood lifted, and the constant achiness in my joints disappeared. One capsule a day - that’s it.

Letter From the Founder

i'm dr. cassie smith,

founder of dynamic d-k2

Vitamin D is one of the most important nutrients your body needs… and one of the most common deficiencies I see in my practice. But here’s what most doctors miss: supplementing D3 without K2 is like hiring movers without giving them an address. The calcium goes somewhere, just not where you want it.

I formulated Dynamic D-K2 to solve this. Clinical-strength D3 at 5,000 IU to correct deficiency and boost calcium absorption, paired with MenaQ7® PRO… the most researched K2 on the planet… to make sure that calcium builds bone, not plaque.

One capsule a day. Stronger bones. Cleaner arteries. Better energy.

FAQs for Dynamic D-K2

What is Dynamic D-K2?

Dynamic D-K2 is a synergistic formula combining high-potency Vitamin D3 (5,000 IU) with MenaQ7® PRO Vitamin K2 (MK-7). Together, they optimize calcium absorption, direct calcium to bones instead of arteries, support immune function, and promote cardiovascular health.

Why do I need K2 with my D3?

Vitamin D3 increases calcium absorption from food, but without K2, that calcium has no guidance. K2 activates proteins that bind calcium to bone (osteocalcin) and prevent calcium from depositing in arteries (matrix Gla protein). Taking D3 without K2 can actually accelerate arterial calcification… the opposite of what you want.

What makes MenaQ7® PRO different from other K2?

MenaQ7® PRO is the most clinically studied vitamin K2 as MK-7 in the world, backed by 15+ clinical trials at the University of Maastricht led by Dr. Leon Schurgers. It has the longest half-life of any K2 form, providing 24-hour protection from a single daily dose. Most competing K2 products use synthetic or poorly researched forms.

How do I take Dynamic D-K2?

Take 1 or more capsules per day with a meal containing fat for optimal absorption (both D3 and K2 are fat-soluble vitamins). Your healthcare provider may recommend higher doses based on your blood levels.

When will I see results?

Many people notice improved energy and mood within 2-3 weeks as vitamin D levels rise. Bone density improvements typically require 6-12 months of consistent supplementation. Cardiovascular protection begins immediately as K2 activates matrix Gla protein.

Who should take Dynamic D-K2?

Dynamic D-K2 is ideal for anyone with low or suboptimal vitamin D levels, those concerned about bone density or osteoporosis risk, anyone wanting cardiovascular protection against calcification, people with limited sun exposure, and those over 40 (when both D and K status naturally decline).

Can I take this with calcium supplements?

Yes… in fact, Dynamic D-K2 is the ideal companion to calcium supplementation. D3 helps you absorb the calcium while K2 ensures it goes to your bones instead of your arteries. Taking calcium without K2 can increase cardiovascular risk.

Is 5,000 IU of D3 safe?

5,000 IU is a well-established clinical dose used by healthcare practitioners to correct and maintain optimal vitamin D levels. The Endocrine Society considers up to 10,000 IU daily safe for adults. However, we recommend periodic blood testing to ensure your levels stay in the optimal range (50-80 ng/mL).

Can I take this if I’m on blood thinners?

If you are taking warfarin or other vitamin K-sensitive anticoagulants, consult your healthcare provider before taking any vitamin K2 supplement. K2 affects clotting factor activation and may interact with these medications. This does NOT apply to newer anticoagulants like rivaroxaban or apixaban.

Can I take this if I’m pregnant or breastfeeding?

Both vitamin D and K2 are important during pregnancy and breastfeeding. However, always consult your healthcare provider before starting any new supplement during pregnancy to determine the appropriate dose for your individual needs.

How should I store Dynamic D-K2?

Store in a cool, dry place away from direct sunlight. No refrigeration needed.
