Longevity Soft Chews are Fera Pets' NMN supplement for dogs, a chicken bone broth soft chew sold 90 to a jar. The label calls NMN an NAD+ precursor. The store's product data gives the listing a publish date of September 14, 2026.
Each 3.5 g chew lists 175 mg of MCT oil, 75 mg of NMN, 40 mg of resveratrol and 7 mg of MitoPrime, a branded L-ergothioneine. The fifth active, phosphatidylserine, carries two amounts: 60 mg in the product page Ingredients tab and 50 mg on the Product Facts label image. The inactive list opens with chicken bone broth and includes coconut flour, dried bacon fat, oat flour, flaxseed meal, sweet potato powder and spinach, with citric acid and mixed tocopherols named as preservatives. Fera's ingredients page names China as the origin of four of the five actives, and Indonesia and Malaysia for the MCT oil. Per the label, the chews are made in the USA from foreign and domestic components. The manufacturer is not named.
Serving scales with weight. Fera's serving image runs from half a chew under 15 lbs to 4 chews at 76 to 100 lbs, and it stops at 100 lbs. The product page FAQ groups dogs into other bands, 16 to 30, 31 to 60, 61 to 90 and over 90 lbs, and puts the life of a jar at 180 days for the smallest dogs and 22 days for the largest. Chews can be given with or without food.
Fera says each batch is tested by a third party lab for potency and purity. The one certificate it publishes for this product, a Eurofins analytical report on lot 20262123A, covers microbes and heavy metals. With no assay of NMN, resveratrol or any other active in it, the amounts per chew rest on Fera's own published figures. The research Fera links covers single ingredients, not this formula in dogs. The jar carries the Quality Seal of the National Animal Supplement Council (NASC), and NASC's member list on nasc.cc, read September 30, 2026, shows Fera Pets with a green check under Audited for Supplements, which NASC says marks permission to display the seal.
Returns are free for 30 days, with a prepaid label and a full refund. The refund policy dates that window from purchase in one sentence and from delivery in another, and is silent on opened jars.

Fera Pets Longevity Soft Chews for Dogs, 90 soft chews, SKU 4624 - buyer FAQ
How much NMN is in Fera Pets Longevity Soft Chews?
Fera lists 75 mg of NMN per 3.5 g chew. The other actives per chew are MCT oil at 175 mg, resveratrol at 40 mg and L-ergothioneine, sold under the MitoPrime name, at 7 mg. For phosphatidylserine the two sources disagree: 60 mg in the product page text against 50 mg on the label image. Per the ingredients page, the NMN comes from China.
How many Fera Longevity chews a day for my dog, and how long does a jar last?
Fera's serving image gives half a chew under 15 lbs, 1 chew at 15 to 25 lbs, 2 at 26 to 50 lbs, 3 at 51 to 75 lbs and 4 at 76 to 100 lbs. The product page FAQ answers the second question with its own weight bands: a 90 chew jar lasts 180 days under 15 lbs, falling to 22 days over 90 lbs.
Are Fera Pets Longevity chews third party tested?
Fera states that an outside lab checks each batch for potency and purity. The certificate it posts, from Eurofins for lot 20262123A, lists microbe and heavy metal results only: Salmonella not detected per 375 g, lead 11.6 ppb, arsenic 45.2 ppb. No result for NMN or any other active ingredient appears in it, so potency data is not published.
How much are Fera Longevity chews on Autoship?
Autoship takes 20% off, so each delivery of the 90 chew jar costs $39.96 against $49.95 as a one time order, on a schedule of every 30, 45, 60, 90 or 120 days. Fera lets you pause, skip, swap or cancel anytime, and says cancelling resets Autoship progress to 0.
Can I return Fera Longevity chews if my dog will not eat them?
Yes, if you are not completely satisfied, per the refund policy. Email customerservice@ferapets.com with your order number, name and reason within 30 days, and Fera sends a free return label for a full refund. One line of the policy starts that clock at purchase and another at delivery, and nothing in it says whether an opened jar qualifies.
