Best Dog Antioxidant Supplements Buying Guide
1. Glucosamine: This is an amino sugar which is found in cartilage. A dog’s cartilage is in charge of supporting its joints and ligaments. It also aids in absorption of nutrients in the body.
Glucosamine can reduce the rate at which cartilage is broken down in the body. This is important because a faster breakdown of cartilage can lead to its reduced production and the onset of osteoarthritis.
The glucosamine supplement will increase the production of collagen which is the major component of cartilage. It also helps repair damaged cartilage and also reduces inflammation.
2. Chondroitin: This is another amino sugar which is found in cartilage. It works in a similar manner as glucosamine. It reduces the rate of cartilage breakdown and also inhibits enzymes that break down the cartilage.
This supplement also attracts water to the cartilage which makes it swell and become more resistant to damage.
3. Omega-3 fatty acids: Omega-3 fatty acids are essential fatty acids which are not produced by the body but are essential for the body to function properly.
They help improve the health of the cardiovascular system and also reduce inflammation in the joints.
4. Silica: This is an essential mineral which is used by the body to produce collagen. Collagen is an important component of cartilage.
Silica helps maintain the strength of the tissues and supports the immune system. It also reduces inflammation in the joints and muscles.
5. Turmeric: Turmeric is a spice which is used in Indian cuisine. It contains a compound called curcumin which has powerful antioxidant properties.
It helps relieve pain and inflammation in the joints and also improves their function. Turmeric also helps maintain the strength of the connective tissues and improves their elasticity.
6. Vitamin C: Vitamin C is a powerful antioxidant which helps neutralize free radicals in the body. Free radicals cause damage to the body and can lead to the onset of diseases like heart disease and cancer.
This vitamin is also important for the production of collagen which is an important component of cartilage.
