ActivExtend is a liquid supplement for dogs from AlchemyPet, a Laguna Beach, California company run by Colin and Grace Topham. It comes in one 60 ml (2.02 fl oz) pump bottle, and every product in the store is a liquid supplement for dogs. AlchemyPet calls ActivExtend its foundation formula, writes it for adult and senior dogs, and states on the product page that it is for dogs only. Its homepage, though, says it is for every dog at every life stage.
The label panel lists 13 actives per serving of 4 pumps, about 2 ml. They include L-theanine 100, curcumin 75, Virtiva (ginkgo biloba and phosphatidylserine) 43, astragalus 25 and Carniking (L-carnitine) 20. The label prints those numbers without a unit, while the product page and the brand's ingredient library give the same figures in mg. Vegetable glycerin, sodium alginate, Swiss Alpine Water and acetic acid make up the rest. AlchemyPet says the actives are cold processed and sealed in a shell of seaweed-derived alginate. It publishes no study on the finished formula, and its product page says ingredient research is not evidence about this formula.
Dose is set by weight. Label, product page and FAQ agree on 3 pumps a day under 45 lb, 4 pumps from 45 to 90 lb and 5 pumps over 90 lb. The label says to build up to that dose slowly over 3 to 5 days. A product gallery image uses other bands: under 25 lb, 25 to 60 lb and over 60 lb. The product page says once a day, in food or water, while a second FAQ page and that gallery image say to spread the pumps through the day. The product page and FAQ say to refrigerate after opening, and the label says to store it in a cool, dry place. Calories are given only as 7 to 9 kcal per serving across the whole range.
The label cautions against use in pregnant or lactating animals and in dogs under 6 months, and asks owners to consult a veterinarian first. The product page adds a vet check for dogs taking anti-inflammatories or blood thinners, or due for surgery. AlchemyPet says every batch is third-party tested for heavy metals and microbials and that certificates are published by batch code. None was posted on the site pages we read on 2026-09-30, and the FAQ asks owners who need help with a batch code to get in touch. The country of manufacture is not published: the label reads manufactured exclusively for Alchemy Pet.
The product page and refund policy give a 90-day guarantee, with the request due within 90 calendar days of purchase. The money-back guarantee page and the shipping pages give 30 days, and the returns page lists change of mind as an invalid reason. Standard shipping is free on US orders per the product page, the shipping policy says charges are calculated at checkout, and the brand ships within the USA only, with no delivery time published.
