Cellgevity Pen Kit
Cellular Health & Longevity
- Compound
- NAD+ 750 mg, L-Glutathione 600 mg and Vitamin B12 2 mg
- Form
- 3 ml Liquid Cartridge
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.
NAD+ Pen Kit
Cellular Health & Longevity
- Compound
- Nicotinamide adenine dinucleotide (NAD+)
- Form
- 3 ml Liquid Cartridge
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.
L-Glutathione Pen Kit
Cellular Health & Longevity
- Compound
- L-Glutathione (reduced glutathione, GSH)
- Form
- 3 ml Liquid Cartridge
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.
