Strong Choice
This supplement is formulated to support immune function and overall wellness in dogs of all ages, from young adults through seniors. The blend of an NAD+ precursor, antioxidants, omega-3 fatty acids, and milk thistle targets cellular health, immune support, and liver support rather than basic nutrition. It’s best suited as an add-on for otherwise healthy dogs already eating a complete and balanced diet.

Strengths
- Includes an NAD+ precursor (nicotinamide riboside) aimed at supporting cellular health and energy processes.
- Provides antioxidant support with vitamins C, D, and E plus zinc and selenium, which can help support normal immune function.
- Contains omega-3 fatty acids from flaxseed and pollock oil, which can support skin, coat, and general inflammation control.
- Includes milk thistle, which is often used to support normal liver function in dogs.
Considerations
- This is a supplement, not a complete diet, so it must be fed alongside a balanced dog food.
- Pollock oil and flaxseed add nutrients but may not be ideal if your dog has a history of fish or flax sensitivities.
- The product is intended only for dogs over 12 weeks of age, so it is not suitable for very young puppies.

Top 5 Ingredients Explained
01
Milk Thistle
Milk thistle is an herbal supplement used in some pet foods and supplements for its liver-supporting and antioxidant properties, with the active component silymarin thought to help protect liver cells and support detoxification. It is a supportive, non-essential ingredient rather than a nutrient, so pet owners should consult a veterinarian before use because effectiveness can vary by product and dosage, and it may interact with medications or cause mild gastrointestinal upset or allergic reactions in some animals.
02
Pork Bone Broth
Pork bone broth is used as a flavorful palatant and hydration aid in pet foods and toppers, contributing gelatin, collagen-derived amino acids, and trace minerals that can support joint and gut health and make food more appealing to dogs and cats. Owners should note broths may be high in sodium or fat and sometimes contain toxic seasonings (e.g., onion, garlic, xylitol) or bone fragments, so choose low‑salt, properly strained products and treat broth as a supplement rather than a complete diet.
03
Total Omega-3 Fatty Acid
Total omega-3 fatty acid indicates the combined amount of omega-3 fats (commonly supplied by fish oil, algal oil, or flaxseed) added to pet food to support skin and coat health, joint function, cognitive development, and to provide anti-inflammatory benefits for dogs and cats. While beneficial, cats have limited ability to convert plant-based ALA to EPA/DHA and therefore need preformed EPA/DHA; excessive supplementation can increase bleeding risk, add calories, or introduce oxidized fats or contaminants, so sources, dose, and balance with omega-6 should be managed for safety and effectiveness.
04
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.

05
Pollock Oil
Pollock oil is used in dog and cat foods as a source of concentrated marine omega-3 fatty acids (EPA and DHA) and dietary fat, which support healthy skin and coat, joint mobility, cardiovascular function and anti‑inflammatory responses. It provides energy and essential long‑chain omega‑3s but must be sourced and stored carefully to avoid oxidation and contaminants, can cause gastrointestinal upset or reactions in pets with fish allergies, and high supplemental doses may have blood‑thinning effects or interact with certain medications.
