Most pet supplements are a scoop of glucosamine and a marketing promise. Hollywood Elixir is the rare one that reads like a longevity stack built for a dog or cat: NAD+ precursor, glutathione, CoQ10, and a stack of polyphenols in a single daily sachet.
La Petite Labs is a new 2025 US brand, and Hollywood Elixir is its healthy-aging flagship. The formula borrows directly from the human longevity playbook: nicotinamide riboside as an NAD+ precursor, reduced glutathione, CoQ10, resveratrol, quercetin, astaxanthin, plus reishi, spirulina, and blueberry. The pitch is multi-pathway support for cellular aging, antioxidant defense, mitochondrial function, and steady energy in adult dogs and cats, taken as a daily 90-day routine.
Here is the honest part. The individual ingredients have meaningful research in humans and rodents. What does not yet exist is strong, published, dog-specific evidence that any of this measurably extends a pet's lifespan or healthspan. Pet longevity supplementation is an early-stage category, and no daily sachet has been shown to make a dog live longer. Treat Hollywood Elixir as proactive nutrition for an aging pet, not a clinical intervention, and keep your veterinarian in the loop.
A few practical notes. It is built for cats as well as dogs, despite the longevity-dog framing. Pricing is premium for the category, from $89 for a 30-sachet box up to $379 for the 180-count, and it is sold as a subscription-style routine. The brand is Made in USA and says it is third-party tested. As of this writing the product was sold out with a restock list, so confirm availability before you commit to a 90-day plan.
Owners of a healthy adult or senior dog or cat who already buy clean, third-party-tested supplements and want a single daily NAD+ and antioxidant routine instead of assembling one ingredient at a time.

La Petite Labs Hollywood Elixir Longevity System - buyer FAQ
What is actually in La Petite Labs Hollywood Elixir?
Per the brand's own product description, it is a multi-pathway blend led by nicotinamide riboside (an NAD+ precursor), reduced glutathione, and CoQ10, with resveratrol, quercetin, astaxanthin, reishi, spirulina, blueberry, and companion nutrients. It is formulated for adult dogs and cats and is sold as daily single-serve sachets.
Will it make my dog live longer?
No supplement has been shown to do that, and we will not claim it. The ingredients are drawn from human and animal longevity research and are intended to support antioxidant defense, mitochondrial function, and healthy aging, but dog-specific longevity evidence is still early-stage. Think of it as proactive daily nutrition, and talk to your veterinarian before starting, especially if your pet has a medical condition or takes medication.

Verified from La Petite Labs' own store in USD: $89 for 30 sachets, $159 for 60, $199 for 90, and $379 for 180. It is offered as a one-time purchase or as a monthly or 3-month subscription routine.
