Supports cartilage repair and cushions joints so your dog moves more comfortably. While research on glucosamine shows variable results, a randomized clinical trial demonstrated statistically significant improvements in pain and mobility in dogs with osteoarthritis after consistent supplementation (McCarthy 2007).

Many chews only give 400–600 mg/day. Doctor Paws delivers a full 1,000 mg/day, matching the therapeutic doses from clinical trials.

Algal oil provides a clean, plant-based source of omega-3s that support brain, eye, and joint health. DHA from algal oil is absorbed just as effectively as fish oil, with studies confirming that algal-derived DHA raises blood levels comparably to fish-based sources.

Unlike fish oil, algal oil is sustainably grown in controlled environments and contains no heavy metals or ocean contaminants - giving your dog premium omega-3 nutrition from the original source fish get it from.

Taurine supports heart rhythm, brain function, vision, and antioxidant defense. Studies in dogs link taurine deficiency to cardiac issues, while broader research highlights its role in protecting against oxidative damage and maintaining cellular health (Backus 2003; Schaffer 2010; Ontiveros 2020).

By including taurine, Super Chew goes beyond joint care to deliver whole-body support.

L-Carnitine helps the body convert fat into usable energy & supports endurance in the heart muscle.In dogs, supplementation has been used in cases of dilated cardiomyopathy to improve cardiac metabolism, and research shows it plays a role in energy balance and recovery (Keene 1991; Kittleson 1997)

Most joint chews leave L-Carnitine out, but combined with taurine it adds another layer of heart and energy support that sets Super Chew apart.

Chondroitin works alongside glucosamine to protect cartilage and support joint comfort. While research shows mixed results, the combination is widely used in veterinary practice based on their complementary mechanisms - glucosamine builds cartilage while chondroitin inhibits enzymes that break it down.

We pair a clinically strong glucosamine base with a supportive level of chondroitin so your dog receives the proven combination effect without unnecessary filler.

Vitamin C is a powerful antioxidant that helps protect joints and connective tissue from oxidative stress. It also supports collagen production, which keeps ligaments, cartilage, and skin resilient. While dogs can synthesize some vitamin C on their own, studies show that supplementation can boost antioxidant status, especially in aging or stressed dogs (Jewell 2024; Gordon 2020).

Including vitamin C ensures your dog gets extra protection where their natural defenses may fall short.

Chlorella is a nutrient-rich microalga that delivers natural antioxidants, peptides, and chlorophyll. Research in dogs shows chlorella and other microalgae are well digested, palatable, and can support beneficial changes in gut and immune function (Cabrita 2023; Delsante 2022).

Most joint chews ignore microalgae altogether, but adding chlorella gives Super Chew an extra layer of immune and antioxidant defense.

Zinc is essential for skin repair, immune defense, and coat quality. In dogs, organic zinc sources like zinc proteinate are better absorbed than cheaper forms, supporting healthier skin and stronger immune function.

Copper supports connective tissue strength, red blood cell formation, and natural coat pigmentation. Dogs need copper in balance with zinc, since too much of one can deplete the other. The National Research Council's authoritative guidelines on canine nutrition highlight copper's essential role while stressing that controlled amounts are key (NRC 2006).

We include just the right amount to complement zinc without tipping the balance.
