Why We Love It

No artificial additives or GMOs.
Optimal levels of vitamins.
Boosts natural bodily functions.

Main Highlights

No Artificial Additives, Fillers, GMOs, Bulking or Flow Agents. Our product is carefully packaged in sealed glass containers with metal lids which are fully recyclable. Our product is also vegetarian friendly and free from allergens.
Contains optimal levels of elemental Magnesium, Vitamin D3 and Vitamin K2. This complex offers all three factors at a high NRV% to ensure high absorption. Vitamin D3 and K2 and elemental Magnesium are critical for optimal human health.

This leaves the body unable to keep up with calcium metabolism. Vitamin D3, with co-factors K2 and Magnesium, help to mobilise calcium and direct it to healthy places such as bones and teeth, while avoiding deposition in the arteries.
Natural immunity support. Montibus Vita’s D3 K2 Magnesium Complex naturally supports the body’s immune system and can help support immune functions.
Our one-month supply is contained in 100% natural fermented pullulan capsules, which aid absorption and digestion.
