Considering I truly avoided the sun, but upped my supplements - not only my weekly Maximum D3 with 13,000 iu… but a daily 2,000 iu D3 gummies. My D levels were okay at 48. But with sun closer to 80.
This week…I took full advantage of the Dallas sun at the resort pool every other afternoon.
And, because of lower cell turn over with rapamycin… my tan grows not only faster… but stays longer too.

@Agetron Lucky man. I walked in 45F (9am) sunshine and then 60F windy sunshine (3pm) yesterday. I got exposure on my legs and face only for about 1.75 hours. Today will be better I’m told.
I think my current Vit D level of 38 is fine as far as Vit D goes. I need more full spectrum sunshine. Taking more Vit D supplements to get higher Vit D is not be the right move for me. I need to get more sunshine or at least get outdoors more despite cold or rainy weather. It’s my own fault so I’ll fix it. Come on Summer!

I definitely think that sun exposure is physiologically important for vitamin D, retinal light exposure, infrared.
Quick 30 minutes shirtless morning around 7 am jogs when it warms up in Arizona feel great before work.

Dr Brads perspective on the vitamine D question.

First - Stanfield is really great - I often send patients his videos for certain content areas as he is spot on.
He could be right, he could be wrong on this. The problem with the data he is utilizing to support his approach, is that only the supplement amount rather than the blood level is known (in most cases, including every study the endocrine society sources).
If you don’t measure, you have garbage in garbage out.
Target D showed that the US RDA for those deficient was not very effective - actually I think almost 50% of people required 5000 IU (not the 800 IU RDA) and 13% of people required>10000 IU daily to achieve a therapeutic level.
So until we have studies looking at blood levels in those in these studies, I think we have no basis for conclusion. We certainly know low blood levels are associated with bad health outcomes in multiple domains. Until we have data showing that those who have higher blood levels due to supplements rather than sun exposure, have the same bad health outcomes as others with low levels of Vitamin D without supplementation, I don’t think we have no basis to claim that Vitamin D doesn’t at least have some causative relationship.
We might get there once we have the appropriate data.
I’ll have to disagree with Dr. Stanfield on this one - I don’t think we have absolute evidence for supplementation, but I also don’t think we have evidence to support not normalizing and measuring Vitamin D.
I’d also point out with the osteoporosis/fracture stuff - all of my patients are on Vitamin K2 MK7 also 200 mcg or more daily. It’s concerning with the findings on this - but we need to know the outcomes when taking a reasonably evidence based approach of K2 with Vitamin D are.
