Omega-3 Oil for Dogs and Cats

Rx Vitamins Ultra EFA 8 fl oz is a concentrated liquid omega-3 supplement formulated for dogs and cats. The formula uses a high-grade marine lipid concentrate that provides the essential omega-3 fatty acids EPA and DHA, along with lecithin, zinc, biotin, vitamin E, and rosemary extract.

Ultra EFA is designed to support healthy skin and coat, everyday mobility, normal cardiovascular function, cellular health, and overall wellness as part of a balanced nutritional routine.

The liquid format makes it easy to measure and add directly to a pet's food.

High-Potency EPA and DHA

Each teaspoon of Ultra EFA provides 540 mg of EPA and 360 mg of DHA.

EPA and DHA are long-chain omega-3 fatty acids derived from the product's marine lipid concentrate.

These nutrients are central to the formula's nutritional role in supporting normal skin, coat, mobility, cellular, and cardiovascular health.

3,000 mg Marine Lipid Concentrate

Each teaspoon contains 3,000 mg of marine lipid concentrate.

This concentrated marine source supplies the EPA and DHA that define Ultra EFA as a targeted omega-3 supplement for dogs and cats.

The formula is designed as a concentrated liquid rather than a softgel or chew.

Supports Healthy Skin and Coat

Ultra EFA provides EPA, DHA, biotin, zinc, lecithin, and vitamin E as part of a nutritional formula designed to support healthy skin and a shiny coat.

Omega-3 fatty acids can be especially useful as part of a broader skin and coat wellness routine.

Persistent itching, hair loss, redness, or other skin concerns should be evaluated by a veterinarian.

Supports Everyday Mobility

Rx Vitamins positions Ultra EFA as an omega-3 formula that can help support everyday mobility.

EPA and DHA contribute to the product's broader nutritional role in supporting normal inflammatory balance and active movement.

Ultra EFA should not be presented as a treatment for arthritis, pain, or orthopedic disease.

Supports Normal Cardiovascular Function

EPA and DHA are also included to support normal cardiovascular function as part of overall wellness.

Ultra EFA provides these omega-3 fatty acids in a concentrated liquid format together with additional supportive nutrients.

300 mg Lecithin

Each teaspoon provides 300 mg of lecithin, including phosphatidylcholine.

Lecithin contributes to the broader nutritional profile of Ultra EFA and complements the marine omega-3 concentrate.

Zinc, Biotin and Vitamin E

Ultra EFA also includes zinc, biotin, and vitamin E.

These nutrients contribute to the product's skin, coat, and general nutritional-support profile.

Vitamin E also helps complement the oil-based formula.

Rosemary Extract for Formula Stability

Rosemary extract is included as an antioxidant and preservative in the Ultra EFA formula.

Along with vitamin E, it helps support the stability of the fatty-acid blend.

Ultra EFA for Dogs

Ultra EFA is formulated for dogs and can be added directly to food.

The formula provides EPA and DHA together with lecithin, zinc, biotin, and vitamin E to support normal skin, coat, mobility, and overall wellness.

Follow the current label or your veterinarian's recommendation when determining the appropriate amount for your dog.

Ultra EFA for Cats

Ultra EFA is also formulated for cats.

The liquid omega-3 formula can be measured according to body weight and mixed with the cat's regular food.

Cats receiving medications or being managed for an existing medical condition should use supplements under veterinary guidance.

Liquid Omega-3 Supplement

Ultra EFA is supplied as a liquid rather than a capsule or soft chew.

This allows the serving amount to be measured and mixed directly with food.

Shake the bottle well before use and follow the current storage directions.

How Much Ultra EFA Should I Give My Pet?

The current directions recommend 1/4 teaspoon for each 15 pounds of body weight, twice daily.

The serving amount may be modified by your veterinarian based on your pet's individual needs.

Always use the current package label as the final reference.

Ultra EFA 8 fl oz vs. 16 fl oz

Ultra EFA is available in both 8 fl oz and 16 fl oz bottles.

Ultra EFA 8 fl oz provides the same concentrated EPA/DHA formula in a smaller bottle.

Ultra EFA 16 fl oz provides a larger quantity and may be more practical for larger dogs, multi-pet households, or longer-term use.

The best size depends on body weight, serving amount, and how frequently the product is used.

Ultra EFA vs. Basic Fish Oil Supplements

Ultra EFA is more than a simple generic oil because the formula includes a defined marine lipid concentrate supplying EPA and DHA together with lecithin, zinc, biotin, vitamin E, and rosemary extract.

When comparing omega-3 supplements, pay attention to the actual amounts of EPA and DHA rather than relying only on the total oil amount.

How Much EPA and DHA Does Ultra EFA Provide?

Each teaspoon provides 540 mg EPA and 360 mg DHA.

Together, that provides 900 mg of EPA and DHA per teaspoon.

This defined omega-3 content helps make the product easier to compare with other liquid fatty-acid supplements.

Professional Veterinary Formula

Ultra EFA is part of the Rx Vitamins professional veterinary nutritional range.

The product provides clearly identified amounts of EPA and DHA in a liquid formula designed for canine and feline patients.

Veterinary guidance is recommended when omega-3 supplementation is being used alongside medications or as part of management for an ongoing health condition.

Important Use Considerations

Safe use in pregnant animals or animals intended for breeding has not been proven.

If your pet's condition worsens or does not improve, stop administration and consult your veterinarian.

For animal use only. Keep out of reach of children and other animals.

Choosing an Omega-3 Supplement for Dogs and Cats

When comparing omega-3 supplements for pets, consider the actual EPA and DHA amounts, oil source, serving format, species labeling, additional nutrients, bottle size, and serving directions.

Ultra EFA provides 540 mg EPA and 360 mg DHA per teaspoon from a marine lipid concentrate, along with lecithin, zinc, biotin, vitamin E, and rosemary extract.

This makes it a clearly defined liquid omega-3 supplement for dogs and cats rather than a generic fatty-acid oil.

Rx Vitamins Ultra EFA 8 fl oz

Rx Vitamins Ultra EFA 8 fl oz is a concentrated liquid omega-3 supplement for dogs and cats formulated with marine-derived EPA and DHA to support healthy skin and coat, normal mobility, cardiovascular function, cellular health, and overall wellness.

The formula also provides lecithin, zinc, biotin, vitamin E, and rosemary extract and can be measured directly into food.

For pet owners searching for Ultra EFA, Ultra EFA oil for dogs, Rx Vitamins Ultra EFA, or an EPA/DHA omega-3 supplement for dogs and cats, the 8 fl oz bottle provides a clearly defined liquid option.
