- ✓5,000 IU Vegan Vitamin D3 gets 93% of deficient adults to serum sufficiency. At 2,000 IU (what most brands use), only 43% reach it. Sourced from algae and lichen, not animal lanolin.
- ✓180mcg MenaQ7® K2 (MK-7) is the exact dose from the landmark 3-year Knapen RCT, for the calcium-direction step. Most brands use 50 to 100mcg.
- ✓150mg DeltaGold® Tocotrienols are the third step almost no D3+K2 includes. Research suggests they may help support healthy bone turnover, the bone you already have.
- ✓Vegan softgel, no gelatin, non-GMO in an organic MCT oil base for fat-soluble absorption. A clean shell most D3+K2 brands still don't offer.
- ✓The only formula we found combining all 3 clinical actives at the doses the research actually used, in one daily softgel.
D3+K2 Complete™ contains three clinically-dosed actives, one for each step your bones need:
- D3, 5,000 IU, gets 93% of deficient adults to serum sufficiency (the absorb step)
- MenaQ7® K2, 180mcg, directs D3-absorbed calcium toward bones and away from arteries (the direct step)
- DeltaGold® Tocotrienols, 150mg, research suggests they may help support healthy bone turnover (the protect step)

Most D3+K2 products get two things wrong, and most people never find out.
First, the K2 dose. The study showing bone density benefits and reduced arterial stiffness used 180mcg of MenaQ7® K2 for three years. Most brands deliver 50 to 100mcg of generic MK-7. That's 28 to 55% of the clinical dose, and generic MK-7 doesn't carry the published human trial data that MenaQ7® does.

This is a long-game formula, and that's by design.
Vitamin D and K2 work at the cellular level over time. The landmark K2 bone study ran for three years, and the benefits became significant only after the second and third year. That's actually why short studies on underdosed products often show nothing.
IMPORTANT The point isn't a fast "feeling." It's giving your body all three steps, consistently, at clinical doses, for the long haul. Most customers take it daily as part of a long-term bone and heart routine, not for an overnight change.
K2 activates two proteins that D3 alone cannot: osteocalcin (which anchors calcium into bone) and Matrix Gla Protein (which helps keep calcium from depositing in arteries).
Both are dose-dependent. The 2013 Knapen RCT that showed reduced arterial stiffness used 180mcg of MenaQ7® for 3 years. Brands using 50mcg deliver 28% of that dose. The mechanism can't fully activate at sub-clinical amounts.

Yes. D3+K2 Complete™ is third-party tested, GMP-certified, made in the USA, vegan, non-GMO, and free of gelatin, heavy metals, gluten, soy, and artificial fillers. The organic oil base is chosen for fat-soluble vitamin absorption.
NOTE Vitamin K2 and tocotrienols can interact with anticoagulant medications like warfarin or Coumadin. If you take blood thinners, consult your physician before use. For all other medications, separating by 2 hours is a general precaution.
D3+K2 Complete™ uses three separate actives, one for each step your bones need: absorb, direct, and protect.
The vegan D3 (5,000 IU) gets 93% of deficient adults to serum sufficiency, versus 43% at the 2,000 IU most brands use. The MenaQ7® K2 (180mcg) is the exact dose from the 3-year Knapen RCT, for directing calcium to bone instead of arteries. The DeltaGold® tocotrienols (150mg) are the third step almost no one includes; research suggests they may help support healthy bone turnover, the bone you already have.
Most D3+K2 products use two ingredients and call it a day. They absorb and direct, then stop. This one adds the protect step, and every dose matches what the researchers actually used.

Tocotrienols
⚠️ WARNING: The K2 in D3+K2 Complete™ is MenaQ7®, a patented, clinically studied form of Menaquinone-7 with one certified supplier in the world. When their allocation runs out, we cannot switch to a generic source and keep the formula's integrity.
Most brands use generic MK-7 from bulk commodity suppliers. We don't. MenaQ7® is the K2 form with published human clinical trials on bone and arterial outcomes at 180mcg. There is no true substitute.
This is not a marketing tactic...
D3+K2 Complete™ is one of the only consumer formulas using the full 180mcg clinical dose of MenaQ7®. At that dose, we burn through allocation faster than brands using 50 to 100mcg. When supply is constrained, we can't just produce more.
We currently have stock for approximately 2 to 3 weeks at current order volume. MenaQ7® lead times have stretched to 10 to 14 weeks due to increased demand across the category.
When we have it, we recommend stocking up. Many customers order 3 to 4 bottles for this reason.
D3 + K2
I switched to D3+K2 Complete because of the magnesium cofactor angle. I read that the enzymes that convert D3 to its active form require magnesium, and I was almost certainly magnesium deficient too. That would explain why my D wasn't budging.
Eight weeks later: D levels at 61 ng/mL. My doctor asked what I changed. I explained the cofactor issue. She went quiet for a second and said "that actually makes sense." That was enough for me.
The Knapen study kept coming up — 180mcg of MenaQ7 K2 for 3 years showed measurable reduction in arterial stiffness. Every product I found was using 45 or 100mcg. D3+K2 Complete was the only one I found using the actual study dose.
Six months in, my follow-up scan showed no progression. My cardiologist said "whatever you're doing, keep doing it." He didn't ask what it was. I told him anyway. He looked it up right there in the office.
Someone in a health optimization group pointed out that D3 without magnesium is like having a key without a lock. The enzyme that converts it needs magnesium to work. I was probably deficient in both and fixing one without the other wasn't enough.
Four weeks on D3+K2 Complete and my afternoon energy is unrecognizable. I used to need a second coffee at 2PM just to get through the rest of the day. I haven't needed it once this month. My mood is steadier. I actually want to go outside after work instead of collapsing on the couch.
The magnesium-D3 connection is real and well-documented. The Vanderbilt-Ingram Cancer Center data showed magnesium supplementation alone increased the efficacy of D3 by 30%. Most pharmacists — myself included until recently — weren't telling patients this.
D3+K2 Complete is the first consumer product I've found that gets all three right: the D3 dose (5,000 IU), the K2 dose (180mcg MenaQ7®, not generic), and the magnesium cofactor. The zinc and boron additions are evidence-based too. I now recommend this to patients before anything else on the shelf.
I started researching K2 after reading that calcium supplements without K2 can actually increase calcification risk. D3 pulls calcium in. K2 tells it where to go. Without K2, the calcium I was taking wasn't going to my bones — it was going somewhere else.
Switched to D3+K2 Complete for 8 months. My most recent DEXA showed a 2.1% improvement in lumbar spine density. My doctor called it "statistically meaningful." I called it the first good news I've had from a bone scan in three years.
I know correlation isn't causation. But I also know D3 at adequate blood levels is one of the most well-documented immune regulators we have. The difference is I was finally taking enough of it, at the dose that actually gets most people to sufficiency.
2,000 IU was doing almost nothing for my levels. 5,000 IU with the magnesium cofactor was a different thing entirely. My doctor confirmed my D levels hit 58 ng/mL at my annual physical. First time I've ever been in the optimal range.
Switched to D3+K2 Complete four months ago. The difference I notice most is energy — specifically that I don't feel like I need to drag myself through the afternoon anymore. I didn't expect that from a D3 supplement. Turns out active vitamin D is involved in mitochondrial function. When it actually activates properly, it's different.
Also worth noting: the boron addition is something I've never seen in another D3+K2 product. I looked it up — it genuinely does inhibit the enzyme that breaks D3 down. It's not a marketing gimmick. This formula is built by people who read the actual studies.
