Follow the dosage instructions on the packaging, as serving size and schedule vary by formulation. NAD+ precursors are commonly taken in the morning, as they engage energy metabolism pathways, though confirm timing with the label or your practitioner.
Qualia NAD+ is a supplement from Qualia Life Sciences designed to support NAD+ levels in the body. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell, where it plays a central role in energy metabolism and DNA repair. Levels decline with age, and that decline is studied in connection with reduced cellular resilience, slower recovery, and fatigue that does not track neatly with sleep or lifestyle.
This product is positioned in the NAD+ precursor category - a class that typically works by giving the body the raw materials it needs to synthesise or recycle NAD+ rather than delivering the coenzyme itself, which is poorly absorbed orally. It may suit people in midlife or older who are actively managing their longevity markers, those experiencing persistent fatigue with no clear nutritional deficiency identified on bloods, or individuals in demanding training blocks where cellular recovery is a priority.
NAD+ precursor supplements are a maturing area of longevity science, with growing human trial data. The honest caveat is that the evidence is still building, and individual response varies. Qualia Life Sciences is a brand known within the precision health space for formulating to a clinical standard, with particular attention to ingredient selection within each category. Check the packaging for the precise precursor compounds, dosages, and any relevant cautions, as formulations in this category differ meaningfully between products.

Your Profile
Your first order creates it. Add your blood results or a wearable, and a doctor can recommend what suits you.
Sign inNAD+ is a coenzyme involved in cellular energy production and DNA repair. Its levels fall significantly with age, and that decline is associated with reduced mitochondrial function and cellular resilience. Supporting NAD+ levels is one of the more studied targets in longevity medicine.
Most people who respond to NAD+ precursor supplementation report changes over several weeks rather than days. Energy and recovery are the most commonly noted effects, though individual response varies considerably and some people notice little change — particularly if their fatigue has a different root cause.
People who are pregnant, breastfeeding, or on medications that affect cellular metabolism should speak to a doctor before use. Check the packaging for the full contraindications list, as this depends on the specific precursor compounds in the formulation.
Standard niacin (vitamin B3) is an NAD+ precursor, but this product is formulated specifically within the NAD+ longevity category, which typically uses more targeted precursor forms. The precise compounds in this SKU are listed on the packaging — worth checking if you are comparing formulations.
It is not strictly required, but it is useful. A baseline panel can rule out more straightforward causes of fatigue — low ferritin, thyroid dysfunction, vitamin D deficiency — and gives you something to compare against if you want to track the effect of supplementation over time.
Overall

Been taking this for about six weeks now, primarily because my bloods came back fine but I was still dragging every afternoon. Hard to say exactly what's shifted, but the 3pm slump I'd had for years is genuinely less pronounced. I stack it with magnesium glycinate in the evening and take this one in the morning with food. Nothing dramatic, just quietly effective.

I'm 52 and have been actively tracking various health markers for a couple of years. Added this after doing a fair bit of reading on NAD+ precursors. Too early to see anything in bloods but subjectively my recovery after longer runs does feel quicker. Will update if anything changes. Happy with the quality so far.

Swapped from a cheaper NR-only product a couple of months ago. Can't do a controlled experiment obviously, but I feel like I'm getting more out of this. Energy during my early morning workouts feels steadier. No jitters, no crash. Worth the extra spend in my opinion.

I've been using this for about eight weeks and I do think it's doing something — less fatigue by mid-morning, better focus in the afternoons. My only gripe is the capsule size. They're quite large and I struggle to swallow them comfortably. Wish there was a smaller capsule or a powder option. Results are good though, and I'll keep ordering.

Came recommended by my GP who is also into longevity medicine. Three months in and I feel well-rested more consistently. Subtle but real.

I work in biomedical research so I went through the ingredient list carefully before buying. The precursor selection here is more considered than most products I've looked at in this category. Subjectively I've noticed better mental stamina on long days in the lab. Early days still but I'm cautiously positive.
