Leap Years® Product FAQs

What are the active ingredients?

LY-D2 (brown) is 200mg of an NAD+ booster.

LY-D6 (golden) is 600 mg of a combination of NAD+ booster and senolytic.

Does Leap Years® contain NMN (nicotinamide mononucleotide)?

No. The family of NAD boosters includes NMN (nicotinamide mononucleotide), NR (nicotinamide riboside), NAR (nicotinic acid riboside) and NA (nicotinic acid). These NAD boosters are chemically modified in the body to be converted into NAD (nicotinamide adenine dinucleotide). NAD is composed of vitamin B3, a sugar and a phosphate. NAD is an important cofactor for many cellular processes. NAD is important to aging, not only because its concentration wanes with age, but it is involved in the activation of sirtuins, enzymes important in DNA repair, controlling inflammation and antioxidant activity, important cellular mechanisms of aging.

What might happen if my dog eats all of the chews in the bottle at once?

We have tested up to 30 times the daily dosage in a safety study in dogs and found no adverse effects. In the event of overdosage, please seek veterinary advice.

Should my puppy take Leap Years®?

Puppies and young dogs (< 50% of their expected lifespan based on breed) do not need Leap Years®. Young dogs have adequate stores of NAD+ and would not have many senescent cells unless there was concomitant inflammatory disease. Specific diseases should be discussed with your veterinary professional. NAD+ concentrations start to wane in middle age.

Can humans take Leap Years®?

No. Leap Years® has been tested in dogs only and is not labeled for human use. Please keep the soft chews out of reach of children.

What do you mean by “healthy aging” for my dog?

Healthy aging means that your dog stays strong and flexible with age. Your dog feels vital and engaged and doesn’t suffer from age-related diseases. Healthy aging depends on specific genes, epigenetics, blood chemistry and more. Regular veterinary checkups with diagnostics and discussion of goals for your dog go a long way to support healthy aging.

Can I slow down aging in my dog?

Aging is caused by genetic, environmental and lifestyle factors. The way to slow aging varies from dog to dog because it depends on individual health parameters. You can slow the aging process in your dog through addressing medical needs, lifestyle changes, supplements and providing a rich environment for engagement.

What is the difference in color between the soft chews?

LY-D6 is a golden color because it is a combination of the NAD+ booster and senolytic and is administered on two consecutive days per month.
LY-D2 is brown and it contains the daily NAD booster only.

Do you ship outside of the United States?

No, currently Leap Years® is shipped free within the continental United States and for a small fee to Alaska and Hawaii.

Leap Years® is shipped within the next business day. You will receive a confirmation email when it is on its way.
