Inside this capsule
This capsule
Vitamin K2
MK-7 from natto · 100 mcg
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: Gnosis (MenaQ7).
A typical blend capsule
ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?…
“Proprietary blend, 1,200 mg” — many names, one number, no way to know how much of anything you took, or what competes with what inside.
On the evidence
Vitamin K's role in maintaining normal bones is an authorised nutrient function.

Repeated randomised human trials
Every ingredient in the catalogue carries one of these three grades — including the ones we grade down. A scale you never see the bottom of is not a scale.

Take it with / keep it apart
Single ingredients let timing work for you — blends lock everything into one swallow.
◎ Pairs well with Vitamin D3
D3 raises calcium availability; K2 activates the proteins that direct it toward bone. → Take together with a meal containing fat. (NIH ODS Vitamin K Fact Sheet)

- ★★★★★Gift link surprised my mum
Sent the set to my mother through the gift link and she could see exactly what was in it before accepting. She's picky — she approved.

- ★★★★★Quietly good
Nothing flashy. Ordered, arrived in five days, matches the label, certificate loads. That's all I ask and almost nobody does it.
Anong P. · SG · 2026-08-07
- ★★★★★Finally, one thing per capsule
I've read too many labels that say 'proprietary blend 1,200mg'. Here it's one ingredient, one dose, printed. Bought two singles instead of my old multi.
