FAQs
Premium dog food is a strong foundation, but even the best diet won’t cover every nutrient or functional area you may want to support, especially if you’re aiming for optimal whole-body wellbeing across digestion, mobility, skin and coat condition, calm focus, daily energy, immune resilience and healthy ageing foundations. That’s why many paw parents add a daily chew, it helps fill common gaps in a simple, consistent routine that’s easier to maintain than stacking multiple products.
BioNAD Longevity+® is The Fittest Pet®’s vet-formulated all-in-one daily soft chew for dogs, built to support six pillars of healthy ageing: Brain & Calm, Joint & Mobility, Energy & Vitality, Gut & Immune, Skin & Coat, and Advanced Antioxidants, so paw parents can support whole-dog wellbeing in one simple, convenient routine. Unlike a generic multivitamin that mainly covers standard vitamins and minerals, an all-in-one daily chew combines essentials with functional actives that support multiple systems for whole-body healthy cellular ageing, helping reduce routine complexity and avoid supplement stacking.
Yes. BioNAD Longevity+® is designed for daily use when fed according to label instructions. It’s a vet-formulated, quality-controlled all-in-one chew with clear weight-based dosing, made to be easy and consistent as part of your dog’s routine.
If your dog is under 12 weeks old, pregnant or lactating, or on medication, check with your veterinarian first.
Give BioNAD Longevity+® daily based on your dog’s weight: <10 kg: 1 chew/day; 11–25 kg: 2 chews/day; >25 kg: 3 chews/day. You can give the full daily amount at once or split morning and evening if that suits your routine. Consult with your veterinarian first if your dog is under 12 weeks old, has a medical condition, is pregnant or lactating.
Most paw parents start when they want a more complete daily baseline, either proactively before anything looks “wrong”, or when they begin noticing problems across the pillars, such as: slower movement or stiff joints, more sensitive digestion or inconsistent stools, itchiness or coat dullness, lower energy or stamina, increased stress around noise or routine changes, or subtle shifts in focus, responsiveness, calmness, anxiety etc.
Starting earlier can make daily care simpler and more consistent, because it’s easier to maintain one all-in-one routine than to patch gaps later with multiple separate products.
Every dog is different, and results vary depending on age, baseline diet and consistency. With daily use, many paw parents notice small “everyday wins” within a few weeks, including steadier digestion and stool quality, less bloating or gas, a softer coat and healthier skin feel, easier settling during noise or routine changes, calmer focus on walks, steadier energy through the day, or more comfortable movement. Broader changes that reflect whole-body, cellular-level support often build over 6–12 weeks as the daily routine becomes consistent.
In most cases, you can keep it simple. BioNAD Longevity+® is designed as an all-in-one daily supplement chew across SIX Pillars (Brain & Calm, Joint & Mobility, Gut & Immune, Skin & Coat, Energy & Vitality, Advanced Antioxidants), so many paw parents don’t need to stack extra products. If your vet has recommended something additional for a specific need, BioNAD Longevity+® can usually be used alongside it. If your dog is on medication or you have any concerns, check with your veterinarian.
If your dog is stiff after rest, slower on walks, hesitant on stairs, or less keen to jump, daily mobility support usually focuses on joint structure, cushioning and lubrication. Nutrition ingredients commonly used for dog joint support include collagen, glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and boswellia, alongside maintaining a healthy body weight and regular gentle movement. If changes are sudden, worsening, or your dog seems uncomfortable, check with your veterinarian.
BioNAD Longevity+® includes these joint-support nutrients as part of its six-pillar daily chew for whole-body support.
Itching and scratching can be linked to fleas, allergies, seasonal triggers, diet changes, dry skin, or skin barrier sensitivity. From a nutrition perspective, paw parents often look for ingredients that support the skin barrier and coat condition, such as DHA/EPA omega-3s, zinc, biotin, vitamin A, vitamin E, copper and vitamin D3. If itching is persistent or comes with redness, hotspots, hair loss, odour, ear irritation or broken skin, it’s best to speak with your veterinarian.
These nutrients are included within BioNAD Longevity+® as part of the Skin & Coat pillar, alongside five other pillars.
A steadier gut routine usually starts with consistent feeding, avoiding sudden diet changes, hydration, and limiting rich table scraps. Many paw parents also choose microbiome support ingredients like postbiotics and prebiotic fibres (such as inulin and FOS), plus functional fibres like beta-glucans, which can support digestive balance and everyday immune resilience. If your dog has ongoing diarrhoea, vomiting, blood in stool, or rapid changes in appetite, check with your veterinarian.
BioNAD Longevity+® includes postbiotic and prebiotic fibres within its Gut & Immune pillar as part of a broader six-pillar routine.
As dogs mature, “slowing down” can reflect changes in mobility, metabolism, sleep quality and overall recovery. Daily support often focuses on cellular energy pathways and nutrient metabolism, alongside comfortable movement so activity stays easy. Nutrition ingredients commonly used for senior vitality include NR (a vitamin B3 form), B vitamins, CoQ10, L-carnitine, taurine, magnesium and betaine, plus maintaining a healthy body condition and consistent, gentle exercise. If your dog has sudden lethargy or a marked drop in energy, speak with your veterinarian.
BioNAD Longevity+® is designed to taste like a treat to support easy daily compliance. If your dog is cautious, start with small pieces for a few days so your dog settles into the routine.
