Even at the same body weight, cats can respond differently to omega-3 depending on sensitivity, digestion, and kidney care needs. Greycoat Omega-3 offers three dosing options to reflect these differences.

For sensitive cats · Early kidney care
- · Prone to vomiting, acid reflux, or diarrhea

→ A low-burden option for sensitive cats
② 150mg · 1 capsule/day
For stable digestion · Daily kidney care

- · Previously tolerated omega-3 well
- · For maintaining a consistent kidney care routine

③ 100mg × 2
Split dosing · Morning & evening
- · When kidney and heart care are considered together
- · When multiple medications or supplements are used
- · When higher single doses cause digestive discomfort
- · When a more stable, split routine is needed
→ A split-dose option for better tolerance
Individual blister packs
Omega-3 can oxidize quickly when exposed to air. To help preserve freshness, Greycoat Omega-3 is packaged in individual PTP blister packs — each capsule sealed separately. This helps protect the oil from oxygen and moisture, reducing the risk of oxidation.
High-purity EPA & DHA from Germany
Greycoat Omega-3 uses EPA & DHA sourced from KD Pharma (Germany), a global leader in high-purity omega-3 refinement. Only EPA & DHA refined using supercritical fluid chromatography (SFC) are selected, with a focus on purity and stability for daily kidney care.
- · GMP-certified production
- · EPA concentration over 80%
- · Meets strict standards for impurities, oxidation, and heavy metals
Ingredient Information
EPA & DHA
Cat-sized, segmented dosing designed to minimize fat load and stomach burden for sensitive cats during daily kidney care.
Astaxanthin
Selected to complement EPA & DHA as part of a balanced, routine-friendly antioxidant approach. Included to support consistency and stability in gentle, long-term kidney care routines.
Greycoat Omega-3 contains naturally red astaxanthin, which may give the oil a slightly reddish color. This is a normal characteristic of the ingredient and does not indicate oxidation or spoilage.
