Set up Profile nowQualia 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.
NAD+ precursors blend
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.
NAD+ 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 sentiment

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
