Top 7 Fortified Vitamin & Mineral Diets in Canada for 2025: A Veterinarian-Reviewed Guide to Supporting Small Pets' Bone, Coat and Immune Health

Martin Little Friends Timothy Adult Rabbit Food targets rabbit-specific needs with a timothy-based formula that emphasizes high fiber and appropriate pellet sizing while including vitamin support suited to small herbivores. It stands out as a specialist rabbit product compared with the predominantly guinea-pig–focused items in this list, offering a middle-ground price and a technical profile tuned for continuous chewing and gut health. For owners with rabbits who want a timothy-first fortified diet, Martin offers a focused alternative to broader-market feeds like Kaytee or Living World.

Tropican Lifetime Formula Granules (Hagen) is positioned as an economical, complete-life-stage granule that provides steady calcium and vitamin fortification across ages, which is why it appeals as a market leader for budget-conscious owners. In contrast to timothy-only adult maintenance feeds, Tropican’s granulated, all‑in‑one approach limits selective feeding and offers cost advantages, though it can be less specialized for species with strict calcium needs.

Living World Green Vita-Min Powder is positioned as a versatile, plant-forward multivitamin powder that balances a broad micronutrient profile with mid-range pricing, making it a practical choice for everyday supplementation of small pets. Technically, its powder form allows uniform mixing into hay and pellets similar to the Oxbow product, but it leans on botanical additives as a differentiator and is generally more budget-friendly than premium veterinary formulations.

Oxbow Critical Care Herbivore is the category's herbivore-focused leader, formulated as a fiber-rich, easily syringeable paste tailored to rabbits, guinea pigs and other small herbivores. It holds its position through a veterinary-grade fiber profile and palatability that support gut motility better than general high-calorie gels like Vetoquinol Nutri-Cal, while being more species-targeted than broad-market options such as Tomlyn or Kaytee.

Oxbow Natural Science Vitamin C Support leverages the company's research-driven approach to small herbivore nutrition, combining vitamin C with complementary dietary considerations to support animals with higher clinical needs. Although it typically commands a premium price versus simpler water drops, its technical advantage is formulation synergy with Oxbow feeds and husbandry guidance, offering tangible value for owners committed to an integrated nutrition plan. Compared with single-ingredient drops like Oasis, Oxbow is less about minimalism and more about structured, science-backed supplementation.

Living World Green Gourmet Toppers Skin & Coat offers a flexible, budget-friendly way to boost coat health with concentrated flaxseed and herb blends; as a topper it lets owners add targeted nutrients without replacing the staple diet. It stands out for affordability and versatility compared with full-feed products like Vitakraft and Oxbow, though it provides less comprehensive daily nutrition on its own.
