With advanced nutrients that help maintain DNA integrity, energy metabolism, and joint mobility, it keeps your pet youthful, active, and happy by your side.

Features

  • Cellular Longevity & NAD+ Support

Powered by NMN, resveratrol, and fisetin, Youthful Care works at the cellular level to help boost NAD+ levels, protect DNA, and strengthen antioxidant defenses. This advanced longevity blend supports healthy aging and sustained vitality for dogs and cats.

  • Joint, Mobility & Recovery

Formulated with a dual collagen system -- bovine collagen peptides (Type I & III) and chicken collagen peptides (Type II) – plus hyaluronic acid, L-arginine, and AKG, it supports cartilage strength, flexibility, hydration, and muscle recovery, keeping pets active and comfortable.

  • Energy & Daily Vitality

By promoting mitochondrial energy production and metabolic balance, this formula helps pets maintain stamina, resilience, and a playful spirit at every stage of life.

  • Australian Superfruit Antioxidant

Enriched with Kakadu Plum, one of the richest natural sources of vitamin C, Youthful Care provides immune and antioxidant support -- a unique reflection of its Australian-made quality and care.

More About NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is a natural molecule found in every cell of the body. It plays a vital role in:

  • Cellular Energy -- helping cells turn nutrients into usable energy.
  • DNA Protection & Repair -- supporting the body’s natural ability to maintain healthy cells.
  • Healthy Aging -- NAD+ levels naturally decline with age, which is linked to reduced vitality and slower recovery.

Kindly Tail Youthful Care includes advanced longevity nutrients such as NMN, resveratrol, and fisetin, which are known to help support and maintain NAD+ levels in cells.

By supporting NAD+, our formula works at the cellular level to:

  • Boost energy and vitality.
  • Help protect DNA against everyday stress.
  • Support healthy aging and long-term wellness

This is why Youthful Care is more than just a supplement. It’s a blend inspired by longevity science and crafted to help pets live longer, healthier, and happier lives.

    NMN & Trans-Resveratrol

    When it comes to longevity science, NMN and resveratrol are one of the most studied and trusted combinations.

    • NMN helps replenish NAD+, essential for energy, DNA repair, and healthy aging.
    • Trans-Resveratrol, the most bioactive form, works as a strong antioxidant and activates sirtuins (especially SIRT1, the longevity proteins) that rely on NAD+.

    Together, NMN provides the fuel, while Trans-Resveratrol switches on the sirtuins. A synergy that supports cellular vitality, DNA protection, and long-term wellness. That’s why we chose Trans-Resveratrol, the superior form, to maximize effectiveness.

  • Fisetin

    Fisetin is a natural flavonoid found in fruits like strawberries, apples, and persimmons.
    It is gaining attention in longevity research for its role as a senolytic nutrient. It helps the body clear out old, less efficient cells while supporting the renewal of healthy ones.

    Along with its strong antioxidant properties, fisetin may contribute to:

    • Cellular protection against oxidative stress
    • Supporting brain and cognitive health
    • Promoting vitality and healthy aging

    In Youthful Care, fisetin works alongside NMN and Trans-Resveratrol, creating a powerful cellular longevity trio.

  • Collagen Peptides & Hyaluronic Acid

    Collagen is the most abundant protein in the body, forming the foundation of joints, cartilage, skin, and connective tissue. As pets age, their natural collagen production declines, which may affect flexibility and mobility.

    Hyaluronic Acid (HA) is like the body’s natural “lubricant,” helping joints stay hydrated and cushioned. Together with collagen, it supports smooth movement, joint comfort, and skin elasticity.

    In Youthful Care, we use a dual collagen system, bovine collagen (Type I & III, Grass-fed Australian cattle) and chicken collagen (Type II), plus hyaluronic acid, providing both structural support and joint lubrication to keep pets active at every age.

  • L-Arginine & Alpha-Ketoglutaric Acid (A-AKG)

    A-AKG is a unique compound that combines two powerful nutrients:

    L-Arginine is an amino acid that plays a key role in circulation and nitric oxide production, helping blood flow, nutrient delivery, and overall vitality. It also supports muscle health and recovery, which is especially valuable for active or aging pets.

    Alpha-Ketoglutaric Acid (AKG) is a natural compound involved in the Krebs cycle, the body’s energy pathway inside mitochondria. AKG helps sustain cellular energy, metabolic balance, and longevity support.

    When combined, L-Arginine and AKG work together to promote daily stamina, recovery, and mitochondrial health. Helping pets stay active, resilient, and youthful.

Frequently Asked Questions

  • NAD+ is a natural molecule found in every cell. It supports energy production, DNA protection, and healthy aging. Our formula includes nutrients like NMN, resveratrol, and fisetin to help support and maintain NAD+ levels for vitality and longevity.

  • By combining advanced longevity nutrients with collagen, hyaluronic acid, and antioxidants, Youthful Care works at the cellular level to promote vitality, mobility, and overall wellness as pets grow older.

  • Youthful Care provides joint support with collagen peptides, hyaluronic acid, and Boswellia extract, making it ideal for daily maintenance and aging pets. It focuses on protecting cartilage, supporting mobility, and offering gentle anti-inflammatory benefits.

    However, if your pet already has arthritis or joint pain, a traditional joint supplement with MSM, glucosamine, or chondroitin may provide stronger short-term relief, while Youthful Care can be used alongside for long-term support.

  • Yes. Youthful Care supports joint structure and comfort with collagen, hyaluronic acid, and Boswellia. For pets with existing arthritis or pain, it can be used alongside a traditional joint supplement for stronger short-term relief while providing ongoing cellular and longevity support.

  • Yes, Youthful Care can be combined with most daily supplements. Since it already includes collagen, hyaluronic acid, antioxidants, and Boswellia, we recommend avoiding duplicate products with the same key ingredients. If your pet is under veterinary care or taking medication, consult your vet before combining.

  • Youthful Care is suitable for dogs and cats over 6 months of age. While it is especially popular for senior pets to support healthy aging, many owners choose to start earlier as a preventive supplement to maintain vitality and mobility throughout life.

  • Youthful Care is generally well tolerated. In rare cases, sensitive pets may experience mild digestive upset when trying a new supplement. If this occurs, start with a smaller amount and gradually increase to the recommended dose.

  • Youthful Care is designed for daily use, and most pets benefit from consistent supplementation. The key longevity nutrients (like those supporting NAD+ levels) work best when given regularly.

    However, some owners prefer to give their pets a short break — for example, 1–2 days every few weeks — to allow the body’s natural metabolism to reset. This is optional, not required, and may be considered for older pets or those with sensitive digestion or liver health.

    If your pet is under veterinary care or has existing health conditions, we recommend discussing the best approach with your vet.
