Study, Trial or Testing Result Summary

Members OnlyHuman studies

No human study has tested this product or its ingredients for slowing aging or repairing cells and DNA. The main ingredient, a 350 milligram enzyme blend, has no studies for this goal at all. The second ingredient, AstraGin at 25 milligrams, is a branded mix that includes Astragalus, but no study tested AstraGin itself, and its studied dose is unclear. The only related research is in animals using other Astragalus extracts. In pigs fed wolfberry and Astragalus extract for 90 days, liver antioxidant enzymes rose, but a marker of cell damage did not change [1]. In mice and rat brain cells, Astragalus combined with another plant compound reduced brain damage after a stroke-like loss of blood flow and protected the cells' energy-producing parts [2]. In newborn mice with brain injury from lack of oxygen, a different Astragalus extract raised a cell-repair enzyme and reduced nerve cell death [3]. In mice on a high-fat diet, Astragalus extract lowered liver fat, cell damage and inflammation signals [4]. None of these studies measured biological age or used this product, so they say little about what it does in people. Animal and cell studies are never counted.

Biohacker Summary

Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it

The main ingredient, AstraGin, was discussed by three of the ten panelists, and all three use it. One takes it as part of a blend to improve absorption and gut balance, one takes 1 gram in the morning for longevity, and one takes it daily for gut health. Nobody on the panel voiced a caution or said they stopped taking it, but only three people spoke about it, so the picture is thin. Enzymes are a smaller ingredient in this product, and most of the panel who discussed them recommend or use them, mainly to help digest protein and heal the gut, though one advised against making them a daily habit and another would not recommend taking a bunch for digestion.

RAL Summary

Members OnlyTier 4 for Healthy Aging

Tier 3 rests on animal studies of other Astragalus extracts and herb combinations, not on AstraGin or the main enzyme blend, so there is no real study support for this product and the evidence is thin. So it is graded Tier 4, lower than the rules alone gave.

  • Emerging: not enough evidence to rank higher yet.
