All right.

Define medicine 3.0 for me.

I would define it as a type of medicine that focuses equally on the pursuit of lengthening life as it does on reducing the decline of health span and also takes a more personalized approach based on all the best available evidence.

It really depends on the situation.

There are some people for whom the drugs and supplements or hormones really play a minor role.

And then there are other scenarios whereby the difference between life and death.

If a person has hypertension, high blood pressure that is otherwise just completely recalcitrant to the normal measures of weight loss and exercise, being able to use a drug to lower their blood pressure is going to have a dramatic impact on their risk of heart disease and stroke.

And then for other people, you're going to get 90% of the lift out of the other four levers.

My intuition is that the majority of that money would be just as well flushed down a toilet.

Because why?

I think at best, most supplements are unhelpful and some of them are probably harmful, not because of malice, but just incompetence on the part of the people who are making them.

I think there's two ways in which this can occur.

The first is when an active ingredient is there, but it's in a much, much higher quantity than it should be.

Obviously, you can have the opposite problem, which is equally likely or maybe more likely where it's in a significantly lower level than what they're telling you, in which case it's just a homeopathic, useless treatment.

But then, of course, you have the problem where impurities show up, most notably heavy metals.

You think you're buying melatonin and what you're getting is melatonin with lead or something like that.

There are a handful of supplements that I take, and by extension, there are a handful of supplements that many of our patients take.

Name them.

I think for most people, magnesium is a really logical choice.

There are different forms that you can take magnesium in.
