Methylated multivitamins for dogs typically refer to formulas using bioavailable, active forms of B vitamins like methylcobalamin (methylated B12) and sometimes 5-MTHF (methylfolate for B9). These forms are easier for dogs to absorb and utilize, especially if they have genetic variations (like MTHFR mutations, though rare in canines) or digestive issues that impair conversion of standard vitamins. “Absorbable” often highlights overall bioavailability, including chelated minerals and added aids like probiotics or MSM (methylsulfonylmethane) for joint support. Not all dog multivitamins are methylated, but those with these ingredients stand out for better efficacy.
Based on 2025 reviews from vet sites, pet retailers like Chewy and Amazon, and expert guides, here are the top recommendations. These were selected for confirmed methylated ingredients, high customer ratings (4.5+ stars), vet approval, and focus on absorption (e.g., soft chews or powders that mix easily). Always consult your vet before starting, as over-supplementation can cause issues, and needs vary by diet, age, and health.

Quick Tips for Choosing and Using
Dosage: Follow weight-based guidelines (e.g., 1 chew per 20-25 lbs); start low to monitor tolerance.
When to Use: Ideal for raw/home-cooked diets, seniors, or pups with absorption issues (e.g., IBD). Skip if on premium kibble.
Safety: Look for NASC seal; avoid human multis due to dosing risks. Reddit users note methylated B12 helps with energy but can cause jitters if overdone—same for dogs, so vet-check B12 levels first.
Where to Buy: Chewy, Amazon, or brand sites for freshness.
These picks prioritize absorbability and methylation for optimal results. If your dog has specific needs (e.g., joint focus), prioritize MSM-heavy options like Zesty Paws.
