The Vital Renewal Approach
Whole-food, evidence-informed supplements for cats and dogs. A formulation philosophy built around bioavailable nutritional support.
What the Vital Renewal Approach is
CellVra supplements from Natural Pet are formulated through the Vital Renewal Approach, CellVra’s whole-food, evidence-informed formulation philosophy. This approach guides how each formula is developed, bringing together nutrient-dense whole-food ingredients, evidence-informed nutritional research, and targeted isolated nutrients where specific mineral support is required.
The result is a nutritional supplement range designed to provide bioavailable nutritional support for cats and dogs, with each formula developed for a defined nutritional role.
Shop CellVraDeveloped by a Certified Clinical Animal Nutritionist
CellVra cat and dog supplements are developed by Paulette Carpenter, a Clinical Small Animal Nutritionist, with ingredient selection guided by nutritional science, species-specific needs, and the role each ingredient plays within the formula.
The whole-food foundation
When nutrients are delivered within a whole-food ingredient, they arrive as part of a complex food matrix: a naturally occurring combination of vitamins, minerals, amino acids, fatty acids, enzymes, peptides, trace elements, and co-factors that exist together within that ingredient. These compounds interact with each other during digestion, supporting absorption and utilisation in ways that isolated nutrients on their own cannot replicate.
This is the nutritional principle behind the Vital Renewal Approach. New Zealand grass-fed bovine organ powders, New Zealand-sourced marine extracts, organic functional botanicals, and supporting whole-food ingredients each bring this kind of multi-compound nutritional value into CellVra formulas. The companion compounds present within each ingredient help the body access and use the nutrients more effectively, supporting energy metabolism, tissue maintenance, skin and coat condition, connective tissue integrity, mineral balance, digestive comfort, resilience, and everyday vitality.
CellVra formulas are built around three core whole-food ingredient groups: New Zealand grass-fed bovine organ powders, New Zealand-sourced marine extracts, and organic functional botanicals. Supporting whole-food ingredients such as bovine bone broth, kumara, and nutritional yeast are included in selected formulas. Targeted isolated nutrients are added where a formula requires more specific mineral or nutritional support.
New Zealand grass-fed bovine organ powders
Bovine organ powders and tissues are among the most micronutrient-dense animal-based ingredients used in nutritional supplement formulation. Organs are concentrated food sources, and in a small daily serving of powder, they deliver a broad spectrum of naturally occurring nutrition.
Within the CellVra range, selected bovine organ and tissue ingredients include liver, heart, kidney, spleen, adrenal, pancreas, thyroid tissue, bone, and collagen. Ovine pituitary is also used in selected formulas as a sheep-derived glandular ingredient.
Bovine liver is one of the richest natural sources of food-based iron, alongside vitamins A, B12, and other B vitamins, copper, and amino acids. Bovine heart contributes CoQ10 and mitochondrial nutrients associated with energy metabolism. Bovine spleen is particularly high in haem iron and nutrients associated with blood and immune function. Bovine kidney contributes naturally occurring selenium and DAO enzyme. Bovine pancreas provides naturally occurring digestive enzymes, including lipase, protease, and amylase. Bone and collagen contribute food-based minerals and collagen-related compounds that support connective tissue, cartilage, joint health, and skeletal integrity.
Together, these organ and tissue ingredients bring vitamins, minerals, amino acids, fatty acids, peptides, enzymes, trace elements, and tissue-specific nutrients into the formula in food-based form. For cats and dogs, this supports whole-body nourishment, resilience, vitality, skin and coat condition, connective tissue health, and healthy physiological function.
The bovine organ powders and tissues used in CellVra formulas are sourced from 100% grass-fed New Zealand cattle through specialist ingredient supply. Ingredients are hormone-free and antibiotic-free, fully traceable, and prepared using freeze-drying and precision milling processes that preserve nutritional integrity and create a stable, fine powder format suited to consistent supplement formulation.
New Zealand-sourced marine extracts
New Zealand-sourced marine extracts bring a different layer of nutritional support into selected CellVra formulas, one that land-based ingredients alone do not provide.
Green-lipped mussel is used in formulas developed to support joint health, mobility, cartilage integrity, and musculoskeletal function. It contributes glycosaminoglycans, marine lipids including the omega-3 fatty acid ETA, and connective tissue nutrients that support joint lubrication, cartilage structure, and healthy inflammatory balance. For cats and dogs with active lives or changing joint needs, green-lipped mussel is one of the most well-regarded marine ingredients in nutritional formulation.
Green-lipped mussel extends the nutritional reach of the whole-food foundation, adding targeted joint, cartilage, and mobility support from a New Zealand marine source.
Organic functional botanicals
Organic functional botanicals bring a concentrated layer of plant-based nutritional support to selected CellVra formulas.
These plant-derived ingredients are naturally rich in active compounds such as polyphenols, flavonoids, adaptogens, mucilage, beta-glucans, curcumin, silymarin, boswellic acids, and other phytonutrients. Many have a long history of use in traditional herbal practice and continue to be valued in modern nutritional formulation for the specific ways they support normal physiological function.
Within CellVra, each botanical is selected for its nutritional role, naturally occurring plant compounds and the body systems it is intended to support. Depending on the formula, organic functional botanicals may contribute support for liver function, digestive comfort, immune resilience, natural inflammatory balance, joint comfort, stress response, and everyday vitality.
This targeted selection gives each botanical a defined role within the formula, adding plant-based nutritional support that complements CellVra's whole-food foundation and supports the purpose of each blend.
Each botanical is selected based on established research into its naturally occurring compounds and the body systems it helps support.
Together, these mineral-rich botanicals contribute plant-based nutrients, trace minerals, pigments, and phytonutrients that add nutritional depth to selected formulas.
Supporting whole-food ingredients
Supporting whole-food ingredients are used across the CellVra range to contribute food-based nutrition, taste, blend consistency, and feeding suitability.
Depending on the formula, this may include bone broth, kumara, nutritional yeast, and collagen-rich bovine nutrients.
Bone broth and collagen-rich bovine nutrients provide food-based connective tissue nutrition, including naturally occurring amino acids that support joint, skin, coat, and digestive health. Kumara helps with blend consistency and feeding suitability. Nutritional yeast contributes naturally occurring B vitamins and a savoury flavour that can help make the formulas more acceptable to cats and dogs.
These ingredients support the nutritional makeup, taste, texture, and feeding suitability of the finished blend, while keeping the formulas grounded in whole-food nutrition.
Targeted nutrients for specific nutritional support
Targeted nutrients are used when your cat or dog needs nutritional support for a specific body system, function, or nutrient requirement, such as joints, connective tissue, muscles, nerves, skin, coat, thyroid function, or endocrine function.
They are included in selected CellVra formulas alongside nutrient-dense whole-food ingredients. This gives each supplement the right nutritional focus for its purpose, while keeping the Vital Renewal Approach centred on whole-food, evidence-informed formulation.
How targeted nutrients are used
- MSM may be included in joint support formulas to support connective tissue, joint function, and mobility.
- Taurine may be included in feline formulas because taurine has particular importance in cat nutrition.
- Calcium carbonate or calcium citrate may be included where a formula is designed to provide calcium support for bones, teeth, and skeletal strength.
- Magnesium glycinate may be included where magnesium support is relevant to normal muscle and nerve function.
- Zinc amino acid may be included where a formula supports skin and coat health, immune function, or zinc-related nutritional needs.
This formulation approach brings together broad whole-food nutritional support and targeted nutrients in selected formulas, providing more specific nutritional support for cats and dogs where needed.

The CellVra ingredient standard
CellVra was developed because Natural Pet wanted a cat and dog supplement range with a level of ingredient quality, nutritional detail, and formulation control it could stand behind.
The ingredients used in CellVra supplements are selected with attention to purity, origin, processing, consistency, and suitability for use in nutritional supplements for cats and dogs. Depending on the ingredient, this may include organic certification, New Zealand origin, pasture-raised animal ingredients, traceability, freeze-drying, milling, batch consistency, certificates of analysis, and recognised food safety or manufacturing standards.
For animal-derived ingredients, relevant quality markers may include New Zealand origin, grass-fed and pasture-raised sourcing, hormone-free and antibiotic-free status, TSE-free assurance, traceability, and processing through audited facilities.
For organic botanicals and plant-based ingredients, relevant quality markers may include certified organic status, single-ingredient powders, no fillers, no preservatives, and no artificial additives.
For marine and bioactive ingredients, relevant quality markers may include New Zealand origin, traceability, controlled processing, quality testing, and suitability for nutraceutical or animal nutrition use.
This ingredient standard supports the Vital Renewal Approach by bringing together quality ingredient selection, evidence-informed formulation, and nutritional support in a form suitable for everyday use with cats and dogs.
