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.
