The NAD+ Trial That Did Not Go The Way People Expected
Scientists gave people a popular "longevity booster" or a placebo for a full year. NAD+ went up, but it's not as good as it sounds. Here’s what happened, and what it means for the bigger picture.

Beyond the Headline
The NAD+ Trial That Didn’t Go As Expected
NAD+ boosters are sold as fuel for aging cells, including your brain. One just went through a big test on a big claim.
A year of the supplement raised blood NAD+, but it did nothing to slow Parkinson's.
Researchers gave people with Parkinson's either 1,000 mg of nicotinamide riboside (NR, the best-known NAD+ booster) or a placebo every day for a year. Nobody, patients or doctors, knew who got what.
NR is a vitamin that is designed to help increase NAD+. Participants who took the supplement saw NAD+ levels increase. Some who believe in the supplement claimed this as a victory.
However, the people taking the supplement didn’t do better. In fact, they did slightly worse. Their symptom scores crept up while the placebo group’s held steady, and non-motor symptoms like sleep and mood also worsened a bit more in the NR group.
To be clear, NR didn’t cause more serious side effects. It just didn’t help.
This followed research from a few years ago that suggested NR might improve Parkinson’s symptoms, and the company that makes it promoted those results.
When researchers tested the question properly, with hundreds of people for a full year, the benefit disappeared.
It’s also worth knowing that several researchers hold NR patents licensed to that company. Ties like that usually make you skeptical of a positive result. In this case, everyone involved had a reason to hope it worked, and it still didn’t.
That is why it’s important to separate mechanisms from outcomes. Moving a number in your blood isn’t the same as changing how you feel or function.
At this point, there’s no good evidence they protect healthy brains either.
If you or someone you love is living with Parkinson’s, put that money toward a physical therapist or an exercise class designed for Parkinson’s. That’s what neurologists consistently recommend.
Together With OneSkin
Science That Supports Aging Skin
Skin-care labels love the word “renewal.” But most products lack evidence to back their claims. So researchers went looking for something more specific: changes in the cells involved in skin aging.
Scientists found that a peptide called OS-01 reduced markers of cellular aging and inflammation in skin cells.
To understand why that matters, start with how skin ages. Like the rest of your body, it ages at the cellular level. Over time, stressed cells stop dividing but keep releasing inflammatory signals that affect the tissue around them. Cellular senescence is one of the most studied processes in longevity research, and your skin is the one organ where you can actually watch its effects: a weaker barrier, rougher texture, and less elasticity.
