AC4 | To Support Longevity and Wellness in Senior Dogs

Q: What is AC4 designed to support?

AC4 is designed to support overall wellbeing in dogs, including digestion, mobility, immune balance, and healthy cellular function. Its ingredients help support the body’s natural defences and normal cellular processes as part of long-term daily care.

Q: Is AC4 only suitable for senior dogs?

No. While AC4 is especially popular for senior dogs, it can be used by adult dogs of all ages. Its ingredients support overall wellbeing, making it a good option for dogs needing extra daily support at any life stage.

Q: Is AC4 suitable for dogs with sensitive digestion?

Yes. AC4 includes ingredients chosen for gentle digestive support and is suitable for dogs with sensitive stomachs. As with any new supplement, introducing it gradually is recommended.

Q: Is AC4 suitable for long-term use?

Yes. AC4 is designed for consistent, long-term use as part of a daily feeding routine. It works best when used regularly to support ongoing wellbeing rather than short-term changes.

Q: How should AC4 be viewed within my dog’s daily routine?

AC4 is intended as a daily nutritional support product rather than a quick or targeted intervention. It works best when used consistently to support overall balance and resilience as part of a complete diet and healthy lifestyle.

AC4 is designed to support older dogs as their needs change, combining carefully selected natural ingredients to help maintain comfort, digestion, and day-to-day vitality.

DESCRIPTION

If your senior dog is starting to slow down, show stiffness, lose their spark, or struggle with digestion, you’re not alone—these changes are a natural part of aging. But the right daily support can make a world of difference.

AC4 is a natural, vet-approved blend designed specifically for aging dogs, helping them stay active, comfortable, and resilient as the years go on.

Each scoop delivers targeted nutrients that:

Support a healthy immune system
Promote smoother, more comfortable movement
Aid digestion for better nutrient absorption
Help maintain steady, healthy energy levels

No complicated routines or hard-to-swallow tablets—just mix it into their food once a day. Most owners say they notice brighter moods, easier mobility, and better overall vitality within a few weeks.

Made with 100% natural ingredients and trusted by veterinary professionals, AC4 gives your senior dog the daily support they need to feel more like themselves again—happy, active, and ready for every moment with you.

INGREDIENTS

Seaweed Complex (Gigartinales, Fucales, Laminariales)

A carefully selected blend of red, brown, and kelp seaweeds. Naturally provides marine polysaccharides, micronutrients, and supportive compounds for overall vitality in aging dogs. Sustainably sourced with no additives or fillers.

USAGE

Sprinkle the recommended amount over your dog’s food once daily.

Start with just a pinch and increase to their recommended dosage gradually over several days. Use consistently as part of their regular feeding routine.

AC4 is safe to use alongside other supplements when fed as directed. When feeding marine-based ingredients, keep total intake to no more than 5% of your dog’s overall diet to help maintain a balanced intake of naturally occurring iodine.
