Claims are based on the product label and human NR research.

Four Traceable Ingredients.

LongTails discloses the two active doses on the label: 200 mg NR and 1,500 mg hydrolyzed collagen. Bone broth and beef liver round out the scoop. No fillers, no binders, no proprietary blends.

NR (Nicotinamide Riboside)

NAD+ Precursor

NR is a studied NAD+ precursor shown in human trials to raise blood NAD+. That is the cellular-support rationale behind the formula.

Hydrolyzed Collagen

Type I & III Peptides

Type I and III hydrolyzed collagen peptides for skin and coat support, with a dose printed on the label.

Bone Broth Powder

Whole-Food Ingredient

Beef bone broth powder adds whole-food nutrition and a savory routine dogs recognize.

Beef Liver

Whole-Food Ingredient

Beef liver powder adds everyday nutrients in a clean, simple powder routine.

No fillers. No binders. No artificial flavors. No synthetic colorants. No soy, wheat, corn, or dairy.

The LongTails Daily Routine

A daily scoop for proactive adult and senior dog parents. No pills, no chews, no guesswork.

1

Scoop

One serving per day, precision-dosed by your dog's weight. Scoop included.

2

Mix

Stir into wet food, raw, or moistened kibble. Most dogs take to the beef bone broth and liver flavor; picky dogs do best with a warm, wet mix-in.

3

Keep Going

Cellular support is a routine, not a quick fix. Consistency matters, and every dog is different.

Backed by Research

The science stack is honest: human NR research, clear label doses, and a daily dog routine built around compliance.

NAD+ and NR Research

  • Nicotinamide riboside is uniquely and orally bioavailable in mice and humans

    Trammell SA, et al.

    Nature Communications, 2016

    Key finding: NR supplementation raised NAD+ in human blood cells, confirming oral bioavailability in human research.

  • NAD+ metabolism and its roles in cellular processes during ageing

    Covarrubias AJ, et al.

    Nature Reviews Molecular Cell Biology, 2021

    Key finding: NAD+ biology is tied to cellular energy and repair pathways. This supports the formulation rationale.

  • Chronic NR supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults

    Martens CR, et al.

    Nature Communications, 2018

    Key finding: NR was well-tolerated in the cited human trial and raised blood NAD+ at the studied dose.

These studies reflect research on individual ingredients, not clinical outcomes from the LongTails product in dogs.

Common Questions About LongTails NAD+

Clear answers before you start the routine.

How long until I know if the routine is a fit?

LongTails is a daily support routine, not a quick fix. Give it consistent use, watch the everyday moments, and use the 90-day guarantee if it is not a fit for your dog.

Will my dog actually eat it?

Most dogs take to the savory bone broth and beef liver flavor, especially when it is mixed into wet food, raw food, or moistened kibble. If your dog is picky, start with a half serving for a few days and use a warm, wet mix-in. Avoid serving the powder in plain water on its own.

Is it safe for my dog?

LongTails is made in a cGMP facility in the USA with no fillers, binders, or artificial additives. Consult your veterinarian if your dog has a specific medical condition or takes prescription medication.

What age should my dog start?

LongTails is built for proactive adult and senior dog parents. Senior dogs are often the reason people start, but the routine is not senior-only.

Can I use this with other medications?

LongTails is a food-based daily supplement. If your dog is on prescription medication or has a health condition, check with your veterinarian before starting any new supplement.

How is this different from regular chews?

LongTails is a dry powder, not a soft chew. That means clear active doses, no chew binders, and easy mixing into wet food, raw food, or moistened kibble.

How fast will I receive my order?

Most LongTails orders are fulfilled quickly. Subscriptions ship automatically on your schedule with free shipping on every order.
