DESCRIPTION

Pure Sodium Ascorbate with Bioflavonoids

Bio-C is a palatable, easy-to-administer powdered source of supplemental vitamin C combined with bioflavonoids. Sodium ascorbate has a saltier, less sour taste than ascorbic acid and is a potent, water-soluble antioxidant. This form of vitamin C is naturally buffered and thus reduces gastric distress commonly associated with high doses of straight ascorbic acid. Bioflavonoids increase the absorption and utilization of vitamin C.

Vitamin C plays a role in immune function and antioxidant activity, and Bio-C from Rx Vitamins delivers it in a form built specifically for dogs and cats. The formula supplies ascorbic acid to help support normal immune system and antioxidant function as part of a broader wellness plan. It's often used alongside other Rx Vitamins formulas, like joint or immune support products, since vitamin C also plays a supporting role in collagen and connective tissue health. Dosing is based on body weight, making Bio-C easy to add to a pet's daily routine without disrupting an existing supplement schedule.

Vitamin C Supplement for Dogs and Cats

Bio-C from Rx Vitamins is a palatable powdered vitamin C supplement formulated for dogs and cats. It provides vitamin C in the form of sodium ascorbate together with lemon bioflavonoids for antioxidant and nutritional support.

Each scoop provides 500 mg of vitamin C and 400 mg of lemon bioflavonoids. The sodium ascorbate form is naturally buffered, giving the powder a less sour profile than straight ascorbic acid and making it practical for routine administration with food.

Bio-C comes in a 4 oz / 113 g powder and can be used according to the current weight-based directions or your veterinarian's recommendation.

500 mg Vitamin C per Scoop

Each 1/4 teaspoon scoop of Bio-C provides 500 mg of vitamin C.

The vitamin C is supplied as sodium ascorbate, a water-soluble form used in the Rx Vitamins formula to provide supplemental vitamin C for canine and feline patients.

Clearly identifying the amount per scoop makes it easier for pet owners and veterinary professionals to compare Bio-C with other vitamin C products.

Sodium Ascorbate for Dogs and Cats

Bio-C uses sodium ascorbate rather than straight ascorbic acid.

Rx Vitamins describes sodium ascorbate as a naturally buffered form of vitamin C with a less sour taste profile.

This makes sodium ascorbate one of the most important ingredient terms associated with Bio-C and should remain prominent throughout the product page.

Buffered Vitamin C Powder

The sodium ascorbate form used in Bio-C is naturally buffered.

This differentiates the formula from products based only on straight ascorbic acid and helps explain why the powder is positioned as a palatable option for dogs and cats.

For search relevance, terms such as buffered vitamin C, sodium ascorbate, vitamin C powder, and pet antioxidant support all accurately describe the product.

Lemon Bioflavonoids

Bio-C also contains 400 mg of lemon bioflavonoids per scoop.

Rx Vitamins states that bioflavonoids help support the absorption and utilization of vitamin C.

The combination of sodium ascorbate and lemon bioflavonoids gives Bio-C a more defined formulation than a simple single-ingredient vitamin C powder.

Vitamin C for Cats

Bio-C is labeled for cats and provides supplemental vitamin C in a powdered form that can be mixed with food.

The current Google Search Console data shows that “vitamin C for cats” is already one of the strongest search themes associated with this page.

Stratford should therefore make feline relevance clear while still preserving the product's broader dog-and-cat labeling.

Vitamin C for Dogs

Bio-C is also formulated for dogs.

The powder can be incorporated into a dog's feeding routine according to the current weight-based directions or veterinary recommendation.

This gives Stratford an opportunity to target both “vitamin C for dogs” and “vitamin C for cats” without creating separate species-specific product pages.

Antioxidant Support

Vitamin C is a water-soluble antioxidant, and Bio-C is positioned as a nutritional source of supplemental vitamin C for pets.

The formula can support normal antioxidant defenses as part of a broader wellness routine.

It should not be presented as a treatment for disease or as a replacement for veterinary care.

Supports Normal Immune Function

Current product listings describe Bio-C as supporting normal immune function in dogs and cats.

This is appropriate wellness language for the product and can be included naturally alongside antioxidant support and nutritional supplementation.

Stratford should avoid stronger claims that suggest Bio-C prevents or treats infections or immune disorders.

Palatable Powder for Easy Administration

Bio-C is formulated as a pleasant-tasting powder designed for easy administration.

The powder can be sprinkled or mixed with food according to the pet's normal routine.

This can be a convenient alternative for dogs and cats that do not readily accept tablets or capsules.

4 oz / 113 g Powder

Bio-C is supplied in a 4 oz / 113 g container.

The number of days one container lasts depends on the pet's body weight and the amount recommended for daily use.

Because the formula uses weight-based directions, smaller pets generally require less powder per day than larger animals.

Weight-Based Feeding Directions

The current label recommends 1/2 scoop per 10 pounds of body weight twice daily, or as recommended by a veterinarian.

One full scoop equals approximately 1/4 teaspoon.

Always use the current package directions rather than estimating the serving amount visually.

Bio-C vs. Straight Ascorbic Acid

Bio-C uses sodium ascorbate instead of straight ascorbic acid.

Rx Vitamins describes sodium ascorbate as naturally buffered and less sour, which helps distinguish the product from simpler ascorbic-acid-only powders.

This formulation difference is one of the strongest reasons to identify Bio-C as a buffered vitamin C supplement rather than just a generic vitamin powder.

Bio-C vs. General Pet Multivitamins

Bio-C is not designed as a broad multivitamin.

Its primary nutritional focus is vitamin C, supplied as sodium ascorbate, together with lemon bioflavonoids.

Pet owners looking specifically for B-complex vitamins, potassium, amino acids, or broad-spectrum multivitamin support should compare other products based on those ingredients rather than treating Bio-C as an all-in-one formula.

Professional Veterinary Formula

Bio-C is part of the Rx Vitamins professional veterinary formula range.

The formula provides clearly identified amounts of sodium ascorbate-derived vitamin C and lemon bioflavonoids rather than relying on a proprietary vitamin blend.

This ingredient transparency is useful for both pet owners and veterinary professionals when comparing vitamin C supplements.

Part of a Complete Wellness Routine

Bio-C should be used as part of a broader wellness routine that includes an appropriate diet, regular veterinary care, hydration, exercise suited to the individual pet, and other supplements only when needed.

Vitamin C supplementation should not replace diagnosis or treatment of persistent health concerns.

If your dog or cat has an ongoing medical condition or already receives other supplements or medications, discuss the complete routine with your veterinarian.

Choosing a Vitamin C Supplement for Dogs and Cats

When comparing vitamin C supplements for pets, review the form of vitamin C, amount per serving, additional ingredients, species labeling, powder or liquid format, serving directions, and package size.

Bio-C has a clearly defined profile: 500 mg vitamin C per scoop as sodium ascorbate, 400 mg lemon bioflavonoids, canine and feline labeling, powdered administration, and a 4 oz / 113 g container.

Those specifications provide a stronger basis for comparison than choosing a product simply because the front label says “vitamin C.”

Buffered Vitamin C Support from Rx Vitamins

Rx Vitamins Bio-C provides dogs and cats with supplemental vitamin C in the form of sodium ascorbate together with lemon bioflavonoids.

Each scoop provides 500 mg of vitamin C and 400 mg of lemon bioflavonoids in a palatable powdered format that can be mixed with food.

For pet owners searching for Bio-C, vitamin C for cats, vitamin C for dogs, sodium ascorbate for pets, or buffered vitamin C powder, this 4 oz formula provides a clearly defined veterinary nutritional option.
