Greetings to all. I wish to take a moment to emphasise a matter of considerable importance, particularly now that we have officially entered the winter season. Many people may begin to supplement with Vitamin/Hormone D3, as it is essential in the northern regions during this time. Please consider the following points:

– Vitamin/Hormone D production is not a simple/straight process, it depends on many other co-factors

– Every person is different, especially based on their origins, so Hermone D production will look different for everyone and everyone should be adjusting doses according to their needs

And now onto the most important part:

1. Magnesium (bisglycinate especially, as it is absorbed at 80% rate in the body) helps with metabolising Vitamin D. If your Mg levels are too low (and mind me, it is very easy to be deficient as stress depleates Mg levels and we are all stressed unless you have a perfect meditation/relaxation routine set in every day) – your body cannot activate the production of Vitamin D.
2. Vitamin K2 (especially the type of MK-7) is the responsible of activating matrix GLA protein to bind excess calcium and help with arterial health (great flow and flexibility – avoiding cardiovascular disease) so this becomes absolutely essential. p.s.: Vitamin K2 in higher doses was also obserbed to reduce visceral fat in postmenopausal women.
3. Zinc can enhance Vitamin D activity and Vitamin D influences zinc homeostasis (so they work great and best together). Disturbance on their balance leads to cardiovascular issues, immune dysfunction, poor healing, etc. Zinc is an important enabler in the conversion of Vitamin/Hormone D from cholesterol – using your fat for proper hormonal production. Aside being key for healthy sex hormones. p.s.: This supplement comes in hand when one has ”high cholesterol” and low serum Vitamin D.

To summarise, if you are supplementing with Vitamin D3 this winter, then you must get in:

– Mg Bisglycinate (you are welcome to get yours at Jotunheim Nutrition (For Sweden only here, and rest of the world here)

– Vitamin K2 (MK-7), we do not have it right now at Jotunheim Nutrition but stay tuned!

– Zinc, (For Sweden only here, and the rest of the world here)

With that said, I personally like Vitamin D3 from a reliable source of Cod Liver Oil that has been least processed, and that is Rosita. We have been stocking Rosita at Jotunheim Nutrition (Sweden) and still some in stock. It is stored in special conditions of controlled temperature as per Rosita’s production mentions to avoid denaturalisation.
