Generally speaking, Vitamin D3 + K2 is a supplement that you can use daily.
I prefer taking Vitamin D3 + K2 every night after dinner. I usually take it along with my other foundational supplements: Optimal Fish Oil and ProBiota HistaminX.
Pregnant or breastfeeding? Optimal Prenatal and Prenatal Essentials already provide you 4,000 IU of D3 and 100 mcg of K2 as MK7 with each serving. You should not need to supplement with Vitamin D3 + K2 unless your healthcare professional advised you to do so.
The safe daily upper limit intake of vitamin D3 for:
- 4-8 years old is 3,000 IU
- 9 years and above is 4,000 IU
You may use
Vitamin D3 + K2 for kids 4 years old and up. You would not give it to them daily. Instead, you would give it to them every other day. This way, they stay within the safe upper limit range.
If they cannot swallow a capsule, you may open the capsule and empty the contents on a bite of food.
It’s recommended to test your vitamin D3 levels periodically with your doctor. You don’t want them too high or too low. If too high, it can contribute to high blood calcium levels. Ask your doctor to test blood calcium levels if you discover that your D3 levels are in the high range.
There is a lot of confusion about what the ideal vitamin D3 range is. Talk with your doctor about this.
I personally like to see my vitamin D3 levels between 30-50 ng/mL. I know some health professionals like to see vitamin D3 levels quite high for some conditions such as autoimmune disease. Follow your health professional’s recommendation.
Magnesium does support vitamin D3 metabolism. We don’t provide magnesium in any of our vitamin D3 supplements because it’s bulky. That would mean a larger capsule or multiple capsules per serving.
Where can you get extra magnesium? You can get 150 mg of magnesium from either
Optimal Electrolyte or
Optimal Magnesium. I drink
Optimal Electrolyte every day so I don’t need to use
Optimal Magnesium.
