Vitamin D Cofactors in a nutshell

Cofactors need to be adjusted when taking a lot of vitamin D for more than a month

"A lot" is more than 4,000 IU Vitamin D daily (average)
There is virtually no agreement as how much of each cofactor is needed vs vitamin D level
The first three cofactors have, like vitamin D, greatly decreased in the human diet in the past 50 years
The goal is to restore Vitamin D, Magnesium, Omega-3, and Vitamin K back to where they had been
in a nutshell = summed up = condensed

Magnesium

Only about 1 in 300 people seem to be allergic to Vitamin D
but the Vitamin D allergic reaction is often due to lack of Magnesium
Magnesium increases the benefits of vitamin D by about 30% (Mg and Vit. D are synergistic)
Magnesium provides a great many health benefits independent of Vitamin D
100 milligrams of Magnesium (say from Magnesium Chloride) seems to be enough, even with high levels of vitamin D
Some people (not a consensus) believe that only 100 mg of Mg can be taken up by the gut at a time
If possible, take your Magnesium several times during the day - not just once
Overview Magnesium Magnesium category has 209 items

Omega-3

Omega-3 increases active vitamin D - especially in people with poorly functioning livers or kidneys
1 gram of Omega-3 seems to be enough. Note: different brands have widely different bio-availability
I prefer Vetomega brand
Overview Omega-3 Omega-3 category has 232 items

Vitamin K2

K2 Keeps Calcium in bones and out of arteries
Calcification due to K2 deficiency may be a reason for increased mortality for some diseases for high vitamin D
Perhaps 100 micrograms per 2,000 IU of vitamin D (i.e. 500 micrograms for 10,000 IU of Vit D)
Perhaps should not take K2 concurrently with Vitamin D. Vitamin D decreases the uptake of Vitamin K1 by 50%
Overview Vitamin K2 Vitamin K category has 98 items

Calcium

Too much Calcium is associated with cardiovascular problems years later, not stronger bones
Should have less than 750 milligrams of Calcium supplementation
Drinking a lot of water helps flush any excess Calcium from the Kidneys
Overview Calcium Calcium category has 173 items

Boron - good, but not as essential

Boron increases Vitamin D and Magnesium in the body by ~ 20%
Most people Boron deficient now that commercial fertilizers are used
Should have 3-10 milligrams of Boron element daily
Boron can be extremely low cost, less than $0.01 a day
Boron category has 22 items

Zinc - good, but not as essential

Extra Zinc does not appear to increase Vitamin D in the blood
Zinc is, however, essential to make Vitamin D Receptors and utilize Omega-3
Low zinc is associated with many autoimmune diseases,infections, colds, etc
Zinc, like Boron, is extremly low-cost and safe
Zinc category has 25 items

Not co-factors, but have also recently become low and are important for health

Iodine category listing has 22 items along with related searches
Iron category listing has 45 items along with related searches
Vitamin D B12 category listing has 23 items along with related searches

Unfortunately cofactors as pills are costly and typically need to be taken daily

The cost of cofactors is 10X to 100X more than the vitamin D when taken as pills
Bulk supplementation of Vitamin D, Magnesium, Zinc, B-12, K2, Boron etc. - lower cost and easier than pills
- just 40 cents per day as a powder
Many of the cofactors need be taken daily (vs Vitamin D can be taken weekly or bi-weekly)
