I wouldn't read too much into this. These were obese people with vitamin D deficiency. Basically, they were sick. We know that stress shortens telomeres; it stands to reason that getting healthier is going to help some. That doesn't mean that vitamin D is a substitute for cycloastragenol. Cycloastragenol and other astragalus compounds can increase telomere lengths in healthy people, and there is no evidence that vitamin D will do that. I'm not really sure what they mean by telomerase activity anyway. What does it mean for telomerase activity to increase 19%? How is "activity" defined, what is the baseline, and how does it all relate to telomere length?

This study can't say anything about healthy people. They didn't look at any. Obese + vitamin D deficient = 'sick', in my book. Overweight is different from obese. Healthy people, for the sake of this argument, are vitamin D replete. Lengthening telomeres is great, but they didn't show that. They showed an "increase in telomerase activity". I would expect vitamin D to help people more if they have a D deficiency than if they don't, but so what? We still have no evidence that more D would lengthen telomeres in the sort of people who care about their telomere length, and are thus likely to be vitamin D replete. I'm not arguing against D for those who need it. I'm just saying don't get your hopes up too much on this.This study doesn't say that it won't help healthy people, not all skinny people are healthy, and not all overweight people are sick. Whats a healthy person? How many Americans today are skinny and lead a stress free lifestyle? Either way this study does show that Vitamin D is at least helping people who need it the most, not the people who need it the least.
I'll simply summarize in saying that from a longevity standpoint, lengthening Telomeres by any amount is desirable.

The study only showed that "Vitamin D supplementation significantly increased PBMC telomerase activity in overweight African Americans". The rest is speculation.Thank you for managing everyones hopes on this, I for one really appreciate it. Your post includes words like "in by book," or "I would expect." Such unsure footed statements do not specify a stance, what IS your position on vitamin D and TM length?

Such unsure footed statements do not specify a stance, what IS your position on vitamin D and TM length? Its ok to say if you dont know enough about something if you don't, I do it all the time. Do you have a counter study showing a decrease in TM activity that from vitamin D? Or are you trying to convey from a point of opinion that this data will not benefit human longevity?
