Nicotinamide Riboside Chloride (NR-CL)

Nicotinamide riboside is a form of vitamin B3 and a precursor used within the body’s NAD+ biosynthesis pathway. NAD+ is a naturally occurring coenzyme involved in a wide range of cellular reactions. NR and NAD+ metabolism are active areas of human nutritional research.

Pterostilbene

Pterostilbene is a naturally occurring polyphenol structurally related to resveratrol and found in small amounts in plants including blueberries. It has been widely studied in nutritional and cellular research.

Trimethylglycine (TMG)

TMG, also known as betaine, is a naturally occurring compound found in foods including beetroot and spinach. It is commonly used in nutritional formulations alongside other research-led ingredients.

Piperine

Piperine is a naturally occurring compound found in black pepper and is included as part of the four-ingredient Longevity+ formulation.

Longevity+ brings these four ingredients together in one clearly defined daily capsule with transparent ingredient amounts and straightforward dosing.

Quality starts with transparent sourcing and independent analysis.

Longevity+ is formulated using carefully sourced ingredients with clear batch documentation and traceability.

Independent laboratory analysis has been carried out by Campden BRI, a UKAS-accredited UK laboratory. The current testing summary reports analysis of Vitamin B3 (as niacin, corrected for recovery) and piperine, together with microbiological testing including E. coli, yeast, mould, coagulase-positive Staphylococci and Salmonella.

All reported parameters were found to be within acceptable analytical limits.

Full laboratory certificates, including methodologies and accreditation scope, are available on request.
