The video states that if you do not get Vit D testing you can safely start at 2000IUs daily of D3.

But since new research is showing very low Vit D levels in patients with MS now, I think you should get tested, as you may need much higher doses.

People all vary in what their bodies require. We genetically may require more of a nutrient than someone else. Research is just scratching the surface about this.

I would continue with what you are doing so far. The list you are taking is very heart healthy and has no down side, and not very expensive. Most people when they start to use supplements, make additions, or raise or lower dose, to find what works best for them. I think you should give your list now a good 6mos before modifying it.

Calcium/Vit D mixtures only reflect small D doses. That is because the information we have now is very new, and the mixtures reflect the old thoughts about normal D intake/safety.

I would still like to know how much and what type of B12 you are using. The best form is methylcobalamin and should be at least 1mg a day up to 5mg a day, on an empty stomach.
