Arfuny Dog NAD+ Drops: A Science-Backed Approach to Canine Vitality

As pet parents, we share a common goal: to give our dogs the longest, healthiest, most joyful life possible. Yet aging—and the cellular wear and tear that accompanies it—often steals that quality of life, leaving our companions with declining energy, stiff joints, weakened immunity, and a dull coat. Modern veterinary nutrition science now offers a powerful tool to address these challenges at the cellular level: NAD+ (nicotinamide adenine dinucleotide) replenishment.

Arfun’s Dog NAD+ Drops are formulated not as a simple supplement, but as a, multi-targeted nutritional strategy. Each ingredient is selected for its specific role in combating age-related decline, supporting metabolic health, and preserving your dog’s overall resilience. Below, we break down the science behind every component.

1. NR (Nicotinamide Rib) – The NAD+ Precursor

NAD+ is a coenzyme found in every living cell. It is essential for energy production (ATP synthesis), DNA repair, and the activation of sirtuins—proteins that regulate longevity. Unfortunately, NAD+ levels naturally decline with age, leading to reduced mitochondrial function, cellular senescence, and loss of vitality.

Nicotinamide riboside (NR) one of the most bioavailable precursors for NAD+ synthesis. Once absorbed, NR is efficiently converted into NAD+ within your dog’s cells. By boosting NAD+ levels, NR helps:

  • Restore cellular energy metabolism, combatting fatigue
  • Activate sirtuins to support healthy aging
  • Enhance mitochondrial function for improved endurance and cognitive clarity
  • Promote DNA repair and reduce oxidative stress

2. Trans-Resveratrol + Quercetin – A Synergistic Antioxidant Anti-Inflammatory Duo

Oxidative stress and chronic inflammation are primary drivers of aging and age-related disease. Trans-resverat (the active, well-absorbed form) and **quercetin are two potent polyphenols with complementary mechanisms.

  • Trans-resveratrol mimics caloric restriction, activating sirtuins and AMPK pathways. It also supports cardiovascular health, reduces inflammation, and protects neurons.
  • Quercetin is a flavonoid with strong antioxidant and anti-inflammatory properties. It helps stabilize mast cells, reduces allergic responses, and supports immune modulation. Quercetin also enhances the bioavailability of resveratrol, making the combination more effective than either compound alone.

Together, this duo provides a robust defense against free radicals, reduces systemic inflammation, and supports your dog’s immune system as they age.

. Glucosamine Hydrochloride – Joint Cartilage Protection

Joint health is one of the top concerns for dog owners, especially in active, large-breed, or senior dogs. Glucosamine hydrochloride is a building block of glycosaminoglycans, which are essential components of articular cartilage. Unlike glucosamine sulfate, the hydrochloride form is more stable and contains no sodium, making it ideal for dogs with dietary restrictions.

By providing the raw materials for cartilage repair and synthesis, glucosamine helps:

  • Maintain joint flexibility and cushioning
  • Support the natural repair of worn cartilage
  • Reduce age-related stiffness and discomfort
  • Complement other joint-supporting nutrients in the formula

. Passionflower Extract – Calming Stress and Anxiety

Mental well-being is a crucial but often overlooked aspect of health. Stress, anxiety, and environmental hypersensitivity can impact behavior, digestion, and immune function. Passionflower extract (Passiflora incarnata) contains flavonoids and alkaloids that promote GABA activity in the brain, producing a gentle, non-sedating calming effect.

This herbal adaptogen helps:

  • Reduce situational anxiety (e.g., car rides, thunderstorms, vet visits)
  • Alleviate nervousness and hyperactivity
  • Support restful sleep without drowsiness
  • Mitigate stress-induced digestive upset

5. Betaine – Liver Support and Gut Health

Betaine (trimethylglycine) is a donor crucial for liver function, homocysteine metabolism, and health. In dogs, betaine offers multiple benefits:

  • Liver protection: It helps prevent fatty liver and supports detoxification pathways.
  • Gut integrity: Betaine strengthens the intestinal barrier, reducing leaky gut and improving nutrient absorption.
  • Hydration and osmoregulation: protects cells from osmotic stress, especially during heat or exercise.

By including betaine, Arfuny ensures that your dog’s liver and digestive system are optimized to process and utilize all other nutrients effectively.

6. Zinc + Vitamin B5 + Vitamin E + Vitamin – Skin, Coat, and Immunity Complex

The skin is the largest organ and a mirror of internal health. This quartet of micronutrients works in synergy to enhance your dog’s appearance and defense:

  • Zinc – Essential for wound healing, keratin formation, and immune cell function. Zinc deficiency is linked to poor coat quality and skin infections.
  • Vitamin5 (Pantothenic acid) – A key cofactor in the synthesis of coenzyme A, which is central to energy metabolism and the production of skin lipids. It helps maintain a healthy, shiny coat and resilient skin barrier.
  • Vitamin E – A fat-soluble antioxidant that protects cell membranes from oxidation. It reduces inflammation and supports immune responses in aging dogs.
  • Vitamin C – Although dogs can synthesize vitamin C, supplementation becomes beneficial under stress, illness, or aging. It supports collagen production (for skin and joint health) and boosts antioxidant capacity.

Together, these nutrients promote a thick, glossy coat, reduce shedding and dandruff, strengthen the immune system, and protect against environmental stressors.

Why Choose Arfuny Dog NAD+ Drops?

Every ingredient in Arfuny’s formula is dosed based on veterinary research and formulated for maximum bioavailability. The liquid dropper format allows for easy, precise dosing—simply add to your dog’s food or water. No pills, no stress.

This is not a one-dimensional supplement. It addresses the fundamental drivers of aging—from NAD+ depletion and oxidative stress to joint wear and mental anxiety—in a single, synergistic formula. Whether your dog is an energetic young athlete, a middle-aged companion showing early signs of slowing down, or a dog needing comprehensive support, Arfuny Dog NAD+rops provide the nutritional foundation for a longer, more vibrant life.

Give your dog the cellular advantage they deserve. Support vitality from the inside out.
