Answer:

This is not entirely correct. Older people are certainly able to produce vitamin D from sun exposure and can produce adequate amounts, but, for a number of reasons, vitamin D levels tend to be lower in older people, making it important for many to increase sun exposure and/or increase vitamin D in the diet (which may include supplements). More details about this are found in the What to Consider When Buying section of the Vitamin D Supplements Review.

I see that you have tested Nutrilite Cal/Mag D Advanced. However Nutrilite also has a Vitamin D3 2000 IU plus Vitamin K2. Seems like this is the one to have tested for this subject. It seems closer to others tested.

We take a variety of Nutrilite supplements and have for many years. Happy to see more are being tested at ConsumerLab. Thanks
