Hey There! My pharmacist said for women it is recommended for your D3 level to be at least 50 for best results. Mine is at 51 for the first time in over 10 years.

I take Micro Ingredients Brand of D3 (5,000 i.u.) + K2 (100 mcg) for better absorption due to being on a PPI (Protein Pump Inhibitor....Prescription Protonix for Acid Reflux) as these meds cause you NOT to be able to absorb supplements as well.

This brought my low D3 up in a short time. Please talk to you doctor about this before trying as this one is a little higher dosage than what is normally recommended.

Low D3 can make Fibromyalgia worse (I have Fibromyalgia) as it causes you to have more pain and fatigue if it is low.

Hugs & Prayers....
