Cellgevity Pen Kit — 1352 mg / 3 ml
Cellgevity is a three-ingredient formulation combining NAD+ 750 mg, L-Glutathione 600 mg and Vitamin B12 2 mg in one 3 ml cartridge. Each ingredient has a different role in normal cell function, with scientific literature examining them individually in relation to cellular energy, antioxidant defence, metabolism and healthy ageing.
NAD+ is a naturally occurring coenzyme found in living cells. It is involved in the reactions cells use to convert nutrients into usable energy and is also used by enzyme systems connected with DNA repair, cell signalling and responses to cellular stress.
L-Glutathione is an antioxidant produced naturally by the body. It helps maintain the balance between oxidants and antioxidants inside cells and is used by glutathione-dependent enzymes involved in cellular protection and the processing of reactive compounds.
Vitamin B12 is a water-soluble vitamin required for normal red blood cell formation, DNA synthesis and the function of the nervous system. It also acts as a helper for enzymes involved in the metabolism of certain fats and amino acids.
Cellgevity brings these three ingredients together in one cartridge. Published research on the individual ingredients provides useful background on their biological roles, but findings from NAD+, L-Glutathione or Vitamin B12 studied separately should not automatically be applied to the finished combined formulation.
This Nadura full pen kit contains one 3 ml Cellgevity cartridge, one reusable metal pen, 20 ultra-comfort pen needles and 20 alcohol wipes. The complete format is intended for customers who require both the Cellgevity cartridge and the compatible reusable pen system.
Storage: Store refrigerated between 2°C and 8°C. Do not freeze. Protect from light. Keep out of reach of children. Refer to the instructions supplied with the product for handling information.
Cellgevity combines three ingredients involved in different but connected areas of cell biology.
NAD+ helps transfer electrons during the reactions cells use to convert nutrients into usable energy. It is also used by enzyme families involved in DNA repair, cell signalling and responses to cellular stress.
L-Glutathione acts as one of the body's principal intracellular antioxidants. It can directly neutralise reactive compounds and is also used by enzymes involved in antioxidant defence and the processing of substances within cells.
Vitamin B12 acts as a helper for enzymes involved in DNA formation, healthy red blood cell production, nervous-system function and the metabolism of certain fats and amino acids.
These explanations describe the recognised roles of the individual ingredients. They do not, by themselves, establish a particular outcome from the combined Cellgevity formulation.
Cellular energy
NAD+ helps transfer energy through the chemical reactions that allow cells to convert nutrients into usable energy. Vitamin B12 supports separate enzyme steps involved in the metabolism of certain fats and amino acids. Both are connected with normal energy metabolism, although they act in different ways.
Antioxidant defence
L-Glutathione is a major antioxidant found inside cells. It helps manage reactive compounds and supports glutathione-dependent enzymes that contribute to cellular protection and redox balance.
Cell maintenance and healthy-ageing research
NAD+ is used by enzymes involved in DNA repair, cell signalling and responses to stress, while L-Glutathione contributes to the antioxidant systems that help protect cellular components. These pathways are widely investigated in research into cellular maintenance and healthy ageing.
Vitamin B12 and normal cell function
Vitamin B12 is required for normal red blood cell formation, DNA synthesis and nervous-system function. The exact form of Vitamin B12 used in Cellgevity is awaiting confirmation, so form-specific technical information has not been included.

Research into Cellgevity's ingredients covers several different areas of biology. NAD+ is studied for its central role in cellular energy and as a substrate for enzymes involved in signalling and maintenance. L-Glutathione is widely researched as an intracellular antioxidant and as a helper for enzymes involved in cellular protection. Vitamin B12 has established roles in red blood cell formation, DNA synthesis, nervous-system function and normal metabolism.
The available literature therefore provides a scientific basis for explaining what each ingredient does individually within the body.
The exact Cellgevity combination has not been established as a single independently studied formulation. Research on the individual ingredients varies by compound form, dose, study design and delivery method.
NAD+ studies may investigate the body's natural NAD+ pathways, direct NAD+ or precursor compounds. Glutathione research includes different formulations and routes, while the effects of Vitamin B12 can depend on B12 status and the specific form supplied. Findings relating to one ingredient or study format should not be treated as proof of a particular result from the combined product.

NAD+ research spans fundamental biochemistry, cell and animal models, observational human studies and clinical investigations. Across this literature, NAD+ is consistently described as a central redox cofactor and as a substrate for enzymes involved in signalling and cellular maintenance.Reviews have also examined how NAD+ concentrations and NAD+-related pathways may change with age, metabolic stress and disease. This work has made NAD+ metabolism an active area of scientific investigation.

Glutathione research spans fundamental biochemistry, cell and animal models, observational human studies and clinical investigations. Across this literature, glutathione is consistently described as a major intracellular antioxidant and as a cofactor for enzymes involved in peroxide control, cellular protection and metabolic processing.
Research has also examined glutathione in relation to oxidative stress, ageing, immune activity and skin biology. Together, these studies have made glutathione metabolism an established area of scientific interest.
