SRA N°8 Longevity: vitamin B3, spermidine, astragalus and resveratrol
SRA N°8 Longevity combines an essential vitamin, B3, with three actives of very different origins.
A polyamine derived from wheat, spermidine; a root from Chinese tradition, astragalus; and a plant polyphenol, resveratrol.
Energy and natural defences
- Vitamin B3 contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue
- Vitamin B3 contributes to normal functioning of the nervous system and to normal psychological function
- Vitamin B3 contributes to the maintenance of normal skin and mucous membranes
- Astragalus supports the body’s natural defences
Characterised extracts rather than simple powders
The formula is based on characterised extracts: the astragalus is concentrated 50-fold and then standardised for astragalosides, the resveratrol, from Japanese knotweed, is of high purity and the spermidine is extracted from wheat germ.
Vitamin B3 provides the nutritional foundation of the formula, at 100% of the reference intakes per 2 capsules.
In the SRA range
SRA N°8 Longevity is formula no. 8 in the SRA range. It pairs with SRA N°1 Mineral, the mineral base designed to accompany each of the formulas in the range.
