A molecule at the core of cellular function.

NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme found in every living cell. It plays an essential role in cellular energy production and supports normal metabolic function throughout the body.

First identified in the early 20th century, NAD+ has become one of the most studied molecules in longevity and cellular biology research. It functions as a critical intermediary in hundreds of enzymatic reactions — most notably in the conversion of nutrients into usable energy.

NAD+ levels may decline with age. FÄRSK is formulated as a convenient, non-prescription dietary supplement for those looking to support their daily wellness routine.

What NAD+ does in the body.

• 01
  Energy metabolism — NAD+ is central to the conversion of carbohydrates, fats, and proteins into ATP, the cell's primary energy currency.
• 02
  DNA repair — Acts as a substrate for PARP enzymes responsible for detecting and repairing damaged DNA strands.
• 03
  Sirtuin activation — NAD+ directly fuels sirtuin proteins (SIRT1–SIRT7), which regulate gene expression, inflammation, and stress response.
• 04
  Mitochondrial function — Supports the electron transport chain within mitochondria, maintaining cellular respiration efficiency.
• 05
  Cellular stress response — Helps regulate the body's response to oxidative stress and metabolic demands.

NAD+ naturally falls with age — and other factors.

Research suggests that NAD+ concentrations can decrease significantly between early adulthood and middle age. This decline is driven by several compounding factors:

• 01 Increased activity of NAD+-consuming enzymes (CD38, PARP) as the body responds to accumulated cellular damage
• 02 Reduced efficiency in NAD+ biosynthesis pathways as cells age
• 03 Dietary patterns that limit precursor availability (tryptophan, niacin, NMN, NR)
• 04 Chronic metabolic stress, disrupted sleep, and sedentary lifestyle

Supplementing with NAD+ precursors is one way individuals seek to support and maintain healthy NAD+ levels as part of a broader wellness routine.

Supplementation through bioavailable precursors.

NAD+ itself is a large molecule with limited direct absorption. FÄRSK utilises well-studied NAD+ precursors — compounds the body naturally converts into NAD+ — delivered in an oral supplement format for convenience and consistency.

These precursors enter salvage and biosynthesis pathways, allowing cells to produce NAD+ from the inside out. This approach mirrors how the body naturally replenishes its own supply, supporting metabolic processes at the cellular level.
