Antioxidant & Oxidative Balance Support for Dogs

Cellular protection, oxidative balance and healthy ageing support in one daily chew.

AoxiGuard® is the Advanced Antioxidants pillar inside BioNAD Longevity+®, our all-in-one daily chew built around six wellness pillars for whole-body healthy ageing.

Designed for dogs who need help protecting their cells from everyday oxidative stress, supporting healthy ageing and maintaining the internal resilience that becomes increasingly important as they grow older, stay active or move through the years when long-term wellness matters most.

Advanced Antioxidants helps with:

✅ Cellular Protection
 Helps defend cells from everyday oxidative stress, one of the quiet processes linked with ageing over time.

✅ Healthy Ageing Support
 Cares for the deeper cellular foundations that help dogs stay well-supported as they move through adulthood and later life.

✅ Oxidative Balance
 Helps maintain a healthier balance between normal free-radical activity and the body’s antioxidant defences.

✅ Inflammation-Aware Ageing Support
 Nourishes pathways linked with whole-body resilience, especially valuable for dogs whose bodies work harder with age and daily activity.

✅ Immune & Cellular Resilience
 Supports antioxidant systems that contribute to normal immune function and overall cellular wellbeing.

✅ Skin, Eye & Whole-Body Protection
 Provides antioxidant nutrients that also contribute to skin health, visual wellbeing and wider tissue protection.

✅ Active-Dog Recovery & Resilience
 Helps care for cells exposed to everyday metabolic demands from movement, exercise and active living.

✅ A Simpler Daily Routine
 Builds Antioxidant Defence into one complete daily chew, reducing the need for separate antioxidant capsules, turmeric powders or healthy-ageing supplements.

One chew. Six pillars. Complete daily care for the dog who deserves more than the basics.

How Advanced Antioxidants Connects to Whole-Body Health

Advanced Antioxidants does not exist in isolation.

Oxidative stress can affect many systems over time, including cellular health, energy metabolism, immune resilience, skin quality, cognitive wellbeing and healthy ageing.

That is why AoxiGuard® sits inside the wider BioNAD Longevity+® 6 Pillar Protocol:

FAQs

Antioxidants help protect your dog’s cells from everyday oxidative stress, a normal process that increases with ageing, exercise, digestion, environmental exposures and daily metabolism. Oxidative stress isn’t “bad” on its own, but over time it can place higher demand on the body’s natural defences. A strong antioxidant routine supports cellular resilience, immune function, skin and eye wellbeing, and overall healthy ageing, especially for active dogs and dogs entering their mature years.

AoxiGuard® is the Advanced Antioxidants pillar inside The Fittest Pet BioNAD Longevity+®. It’s designed to support cellular protection and oxidative balance as part of a whole-body healthy ageing routine, with added support for everyday immune resilience and skin and eye wellbeing. It’s delivered in a soft chew that tastes like a treat, which makes daily consistency easier than managing separate powders and capsules.

Give BioNAD Longevity+® daily based on your dog’s weight:

  • <10 kg: 1 chew per day
  • 11–25 kg: 2 chews per day
  • >25 kg: 3 chews per day

You can give the full daily amount at once, or split it across morning and evening if that suits your routine. Consult your veterinarian first if your dog is under 12 weeks old, pregnant, lactating, or has medical conditions.

AoxiGuard® is the Advanced Antioxidants pillar inside BioNAD Longevity+®, supporting oxidative balance and everyday cellular resilience, alongside five additional pillars, Brain and Calm, Joint and Mobility, Energy and Vitality, Gut and Immune, and Skin and Coat, in one daily chew.

The best antioxidant support is usually a blend, not a single ingredient. Different antioxidants do different jobs and work like a network. Many owners look for combinations that include a high-value carotenoid (like astaxanthin), a curcumin form that is easier to utilise, plus broader polyphenols and supporting nutrients. Prioritise dog-specific formulas with transparent labelling and clear daily serving guidance. If your dog is on medication or has a medical condition, check with your vet before adding new actives.

A proactive healthy-ageing routine can include quality nutrition, appropriate exercise, maintaining a healthy body condition, regular vet care and nutrients that support cellular energy, advanced antioxidants, joint health, gut balance and brain function.

AoxiGuard™ contributes the Advanced Antioxidants pillar inside BioNAD Longevity+™, where it works alongside five additional pillars for a more complete daily approach to whole-body healthy ageing.

Curcumin is a well-known plant compound used in healthy-ageing and antioxidant formulations. Curcumin phytosome is a more bioavailable form designed to improve how the body can use it.

Inside AoxiGuard™, curcumin phytosome works alongside resveratrol, astaxanthin, carotenoids, vitamin C, selenium and vitamin K₁ to provide broader antioxidant support than a single turmeric ingredient alone.

Astaxanthin is a carotenoid antioxidant known for supporting cellular protection from everyday oxidative stress. Paw parents often choose it as part of a healthy ageing routine because it also supports skin wellbeing, immune resilience, and whole-body antioxidant defence, especially for active dogs with higher metabolic demand. It’s a popular “premium” antioxidant because it complements other nutrients rather than duplicating them.

For dogs, it can be a valuable part of a healthy-ageing routine because it contributes to cellular resilience, skin wellbeing, immune support and whole-body antioxidant defence. In AoxiGuard™, it works together with several complementary antioxidants for a more complete formula.

Not necessarily. Many dog supplements focus on one main concern, such as antioxidants, joints, gut health, brain support, skin and coat or senior wellbeing. That can leave paw parents juggling multiple powders, oils, capsules and chews.

BioNAD Longevity+™ brings Brain & Calm, Joint & Mobility, Energy & Vitality, Gut & Immune, Skin & Coat, and Advanced Antioxidants together in one veterinarian-developed daily chew, helping simplify your dog’s routine while supporting broader daily wellbeing.

Yes. Active dogs place ongoing demands on their muscles, metabolism and cells through movement, exercise and daily activity.

AoxiGuard™ is relevant not only for senior dogs, but also for paw parents who want to support cellular resilience, recovery from daily oxidative demands and long-term healthy ageing in dogs who are still active and thriving.

A proactive healthy-ageing routine can include high-quality nutrition and antioxidant ingredients such as curcumin phytosome, resveratrol, astaxanthin, carotenoids, vitamin C and selenium to support cellular protection and oxidative balance.

AoxiGuard™ gives dogs targeted Antioxidant support inside BioNAD Longevity+™, alongside five additional pillars for whole-body healthy ageing. BioNAD Longevity+™ is a formulated supplementary food, not a treatment for disease. If your dog has sudden changes in health, behaviour or energy, speak with your veterinarian.
