Sunn-E K9 Vitamin E Supplement for Dogs

Dog supplements aren’t regulated, so there’s little, if any, oversight of formulas, ingredient sourcing, or quality control. Brands aren’t required to prove efficacy, and supplements can be inaccurately labeled, improperly dosed, ineffective, and even worse, contaminated with yucky things like mold.

Hype-over-substance dog supplements rely heavily on marketing trends instead of research-backed ingredients and dosage. Without third-party testing or responsible manufacturing practices, purity and potency vary from batch to batch.

Not ours. Here at The Hearty Paw, we only offer supplements with verified quality standards, research-backed and vet-informed formulas, and trusted manufacturing practices.

Every supplement we carry is something we’d confidently give our own dogs to support their long-term health and wellness. We rigorously evaluate each formula for efficacy, ingredient quality, and manufacturing integrity, prioritizing products backed by real standards rather than marketing claims. Most dog supplements on the market don’t make the cut.

Our selection includes third-party tested options to verify purity and potency, NASC Certified products that meet strict quality, labeling, manufacturing, and safety standards, and veterinarian-formulated formulas developed with clinical expertise.

The Hearty Paw prioritizes effective, research-backed formulas made with high-quality ingredients to deliver powerful results you and your dog can feel good about.

BioStar Sunn-E K9 is a full-spectrum Vitamin E oil for dogs formulated to support antioxidant protection and overall cellular health. Vitamin E is a powerful antioxidant that helps neutralize free radicals, supports healthy nerve function, and helps protect cells from oxidative damage caused by normal metabolism, environmental exposure, and aging.

This Vitamin E supplement for dogs is made from non-GMO, hexane-free, expeller-pressed sunflower oil sourced from Spain, preserving the natural balance of tocopherols and tocotrienols. It provides 1,982 IU of full-spectrum Vitamin E per 3 mL, including alpha-, beta-, delta-, and gamma-tocopherols, along with small amounts of tocotrienols.

Dogs with increased activity levels, as well as pregnant and lactating dogs, may have a higher need for antioxidant support. This easy-to-use liquid formula offers a convenient way to incorporate Vitamin E into your dog’s daily routine.

Free from soy, canola, and palm oil, this clean formula delivers a high-quality source of Vitamin E without unnecessary additives.
