Product Description

Sunday Natural combines vegan vitamin D3 from lichens with vitamin K2 in all-trans MK-7 form. The combination makes sense because K2 directs the calcium mobilized by D3 specifically into the bones rather than into the blood vessels.

What We Like

Vegan D3 from lichens — also suitable for vegetarians and vegans
All-trans MK-7 — the most bioactive and stable K2 form
120 capsules = 4 months duration
Excellent value for money

What We’re Missing

2000 I.U. may be too low in winter for some people
No oil-based format (fat-soluble vitamins benefit from this)
No independent third-party seal (NSF, USP)

Ingredient dossier

Low vitamin D levels are common in northern climates. Supplementation is comparatively well studied in deficiency; K2 is often combined but has weaker standalone evidence.
