About MD NAD+

NAD+ and medical authority

The question behind MD NAD+ is how much medical authority a name can acquire. NAD+ is essential to cellular life, and “MD” lends the sound of a consultation. Neither fact settles what a pill or an infusion will change for a person.

My initial impatience with the replenishment story was too sweeping. The muscle insulin-sensitivity result persuaded me that there was a more interesting subject underneath it. Prediabetic, postmenopausal women showed a specific physiological improvement, with unchanged HbA1c and body composition. HbA1c staying unchanged sharpened my curiosity about muscle insulin sensitivity. It supplied a useful question while leaving the larger claims unresolved.

I trust the specificity of that mixed muscle result. An explanation smooth enough to cover everything has much less appeal. The CD38 work in mice is a good example: changing how NAD+ was consumed preserved its supply and mitochondrial function. That finding complicates the idea that the only interesting intervention is adding more raw material.

The MD name

MD NAD+ is the website's name. I am unqualified to practise medicine. These pages cannot assess a person's health or prescribe treatment. There is no appointment desk, product checkout or dispatch department here. Nothing on these pages is medical advice.

A clinician who knows someone's health history can discuss a treatment decision with them. A study result on this site cannot perform that assessment. Questions sent through the contact page concern the accuracy of the published material.

A longer functional follow-up

The 2025 review of human ageing evidence found limited efficacy and sparse tissue-specific measurements. For NAD+ ageing claims, I need a lasting functional improvement tied to the tissue being studied.

That leaves room for enthusiasm. The walking and muscle experiments have given it a useful direction, and the reading list contains the less convenient findings too. A convincing medical reputation will have to accommodate all of them.
