Dr. Shallenberger's NAD Mitochondrial Energy Supplement review
A daily NAD supplement aimed at the kind of tiredness that comes with getting older

Is it worth it?
You're tired in a way coffee stopped fixing. Not sleepy exactly, more like the tank empties by mid afternoon and the stairs feel like more work than they used to. Someone told you that's just your sixties, and you'd rather it wasn't. This is Dr. Frank Shallenberger's answer to that: a daily capsule aimed at NAD, the molecule your cells use to turn food into energy. The argument is that caffeine only borrows energy, while this rebuilds the supply by making your mitochondria work better. Worth separating two things. NAD levels really do drop as people age, and that part is solid. Whether swallowing a supplement raises them enough to change how you feel is much shakier. Trials on NAD precursors mostly show blood markers shifting, not people reporting they feel younger. The page says studies show it boosts energy and mobility, then cites none. That's the seller's claim, not a result. So you're buying a maybe, with the guarantee as your safety net. Some people do feel a lift after a few weeks. Plenty feel nothing and are out the money. One thing first: if this tiredness is new or getting worse, get bloods done. Thyroid, iron, B12 and sleep apnoea are common, testable and fixable, and no capsule substitutes for finding out which one it is.
Pros
- One off payment, no subscription to cancel
- Named doctor behind it with a real, checkable clinic
- Targets something genuinely real (NAD falls with age)
- Money back guarantee advertised on the page
Cons
- Page shown never names the ingredient, dose or price
- Energy and mobility claims are offered with no study cited
- If it works at all, it's gradual and easy to confuse with placebo
What you get
A bottle of capsules you take daily, sold as a one off purchase, so nothing rebills you later. The part of the page shown doesn't name the actual ingredient, the dose, or how many capsules come in a bottle, though the site has an Ingredients tab and a Guarantee tab. Read both before you order, not after.
Before you buy
- Open the Ingredients tab and see which NAD precursor it uses, then price the same ingredient on its own
- Read the guarantee terms: how many days, who pays return postage, whether opened bottles count
- If the fatigue is new, see a GP first and rule out thyroid, iron, B12 and sleep problems
Who it suits
Someone in their fifties or older with no medical explanation for feeling flat, who has money to spend on a maybe and will use the refund if nothing changes
