These are all common dog supplement additives, especially those involving skin and coat health. Knowing a little more about them can allow you to do what I did: either buy the human versions and make my own or make sure the supplements I look at contain a high enough amount of quality sourced ingredients to make them worth buying. It’s also just good to know what to look for in a supplement.
BREWERS DRIED YEAST is rich in Mega fatty acids, B vitamins and antioxidants. It enhances health, aids with flea control and improves the immune system. Improving skin health and coat shine, while reducing itchy dry skin helps minimize shedding due to inadequate nutrition. The B vitamins help with nerve function and stress management, reducing anxiety and balancing hormones including those related to adrenaline and epinephrine.
FLAXSEED meal provides Omega 3 and Omega 6 fatty acids, necessary for good skin and coat health. It aids in making the coat softer and shinier, with healthier skin underneath, while providing dietary fiber. In addition to the omega fatty acids, it contains alpha-linoleic acid, which offers benefits to the immune system. Alpha-linoleic acid also has an anti-inflammatory effect which may help if there are any joint problems. Lignans in Flaxseed contain antioxidants.
(Flaxseed oil or meal is not high enough in these omegas to replace Fish oil.)
FISH OIL with OMEGA 3 & 6 (dogs can’t use 9) EPA DHA
Fish oil can greatly improve skin, coat, joint, kidneys, heart, and immune system health. Fish oil contains two essential fatty acids: EPA and DHA. Both are Omega-3 fatty acids that can only be made in a limited capacity in dogs.
EPA acts as an anti-inflmmatory. It will help with any condition that cause inflammation of the heart, kidneys, skin and joints. It will ease inflammation due to allergies, and reduce itchy skin and dandruff and is used to treat hot spots. It promotes a shiny, healthy coat and reduces shedding.
DHA is important in brain, eye and neuron development. This fatty acids affects cell permeability and the growth of nerve cells which is important for optimal development.
Both EPA and DHA are important components of cell membranes. These unique fatty acids act as signals in cells to decrease inflammation. Less inflammation leads to less pain, redness and swelling in the skin, joints and other organs.
Source matters here because fish oil can contain mercury and other toxins that are much more dangerous for dogs than they are for people.
BIOTIN is a water soluble B vitamin that is essential for protein and fatty acid metabolism. Some common names for biotin include vitamin B-7, Vitamin H and coenzyme R. Biotin supports a healthy nervous system, skin and coat.
We only use Biotin every day.
