Not all
Vitamin D
is the same
Most Vitamin D supplements look similar on the surface. The differences are what's in the bottle, what the bottle is made of, and what happens after you buy it.

Bottle plus printed daily-ritual guide
Vitamin D supplementation only works if you actually take it. Every day, for long enough to matter.* D3X is built around that one fact.
Only three
simple
ingredients
No fillers. No sweeteners. No proprietary blends. Just the three things that actually matter.
01
Vitamin D3
The star of D3X. D3 behaves more like a hormone than a typical vitamin and influences a wide range of processes in the body.2* We use D3 because it's the form your body naturally makes from sunlight, and it's generally more effective than D2 at raising and maintaining Vitamin D levels.3*
2000 IU per serving
02
Vitamin K2 (MK-7)
03
Organic olive oil
Vitamin D is fat-soluble, so it absorbs best with fat.2* We use olive oil as a clean, food-based carrier, naturally rich in antioxidants and a better choice than the seed oils and synthetic carriers most supplements rely on.
Cold-pressed · organic
No sugar, sweeteners, artificial flavors or colors, fillers, dyes, or unnecessary additives. What's on the label is what's in the bottle.
Bottle and a
blueprint
Two things ship in every box. The product, and the printed guide that helps you stay consistent. Because consistency is the whole point.*
The bottle
2000 IU Vitamin D3, 100 mcg K2 (MK-7), organic olive oil. One full dropper a day.
The blueprint
A small printed guide that makes the daily habit stick. Most supplement brands don't include one. We do, because the supplement only works if you actually take it.*
Three steps
That's it
01
One full dropper
Add 1 mL to a beverage, food, or directly under your tongue.
02
Daily, same time
Pick a moment in your routine, like coffee, breakfast, or brushing teeth, and stick to it. Consistency is the whole point.
03
Reassess at 8 to 12 weeks
Vitamin D doesn't work overnight. Best results come from staying on it long enough for your levels to actually rise.*
