What is inside
Each active, and what the research actually looked at.
We name what was studied, the species it was studied in, and the dose. Where the work is not in dogs, we say so.
Open the ingredient library| Active | Per serving |
|---|---|
L-theanine
Why it is in hereAn amino acid found naturally in tea leaves. It supports a settled, even baseline through the day rather than a sedative effect, and at 100 mg it sits exactly where canine behaviour research put it. | 100 mg |
Curcumin (Turmeric Extract)
Why it is in hereThe active fraction of turmeric root, standardised to over 95% curcuminoids rather than the culinary spice. It is the antioxidant backbone of this formula, and one of the ingredients that gains most from being protected on the way through. | 75 mg |
Virtiva® (Ginkgo Biloba, Phosphatidylserine)
Why it is in hereA branded complex pairing ginkgo biloba with phosphatidylserine, a phospholipid found in nerve cell membranes. This is the cognitive component of the formula, aimed at the alertness and recall side of getting older. | 43 mg |
Astragalus
Why it is in hereA root long used in traditional Chinese medicine and now studied in Beagles. Here it supports immune balance, which is the part of healthy ageing owners tend to think about last. | 25 mg |
Carniking® (L-Carnitine)
Why it is in hereL-carnitine shuttles fatty acids into the mitochondria to be burned for energy. Carniking is the one branded ingredient in this range that has been studied in dogs under its own name. | 20 mg |
Ashwagandha
Why it is in hereThree published randomised, placebo-controlled trials in dogs sit behind this root, which is more than almost any other calming botanical can say. In this formula it is here for the stress-and-recovery side of ageing rather than for acute calm. | 15 mg |
Olea25® (Hydroxytyrosol)
Why it is in hereHydroxytyrosol is the polyphenol behind most of what is claimed for olive oil. Here it protects circulating fats from oxidative damage, which is a quiet part of ageing well. | 12.5 mg |
Purple Passion Flower Extract
Why it is in hereA traditional calming botanical that acts on the same GABA pathway as the amino acids alongside it. A supporting note in this blend rather than a lead actor. | 12.5 mg |
Crominex®3+ (Chromium, Amla Extract, Shilajit)
Why it is in hereA chromium complex stabilised with amla and purified shilajit. It supports the insulin-signalling side of metabolism, which is one of the first systems to drift with age. | 5 mg |
Vitamin K2 (K2Vital® MK-7)
Why it is in hereThe menaquinone-7 form of vitamin K2, from K2Vital. Its role is directing calcium into bone rather than into soft tissue. Included at a supporting level. | 1.64 mg |
Panax Ginseng
Why it is in hereA classic adaptogenic root. At this level it is a supporting element of the blend, included for its contribution alongside the other adaptogens rather than on its own. | 1.25 mg |
Rhodiola Rosea Extract
Why it is in hereAn arctic adaptogen used traditionally for resilience under load. A minor supporting component of the blend at this level. | 1 mg |
AstaPure® (Astaxanthin)
Why it is in hereA red carotenoid from Haematococcus pluvialis microalgae, and one of the few antioxidants that spans a cell membrane rather than sitting at one face of it. Here it works alongside the other antioxidants rather than carrying the formula alone. | 0.5 mg |
What this does not say. Ingredient research is not evidence about this finished formula, and none of it establishes treatment of any diagnosed condition. The absorption figure we publish comes from published microencapsulation research, not from a study on a finished AlchemyPet formula.
