Macaws or cockatoos are among the longest-lived parrot species. And just like us, their healthcare needs change as they age, especially their nutritional requirements. With Senior bird nutri-berries, we've created a diet to give your bird all the nutrients he needs during his golden years without having to sacrificing taste or texture. We added herbs like milk thistle for its anti-inflammatory and anti-arthritic effect, as well as dandelion to support bone health and improve liver function. We included ginger a powerful anti-inflammatory herb to help ease tendonitis, lower cholesterol and blood pressure and to help prevent blood clots. We also combined the joint-health supplements glucosamine, to combat osteoarthritis and chondroitin, to ease joint pain and swelling. Senior bird nutri-berries are also packed with real pieces of age-defying fruits plums, which provide dietary fiber and are high in vitamins A, C, K, potassium, fluoride and beta-carotene, cranberries, which are full of antioxidants that strengthen the immune system by flushing out harmful toxins and dates, which are iron-rich fruits that contain flavonoid polyphenolic antioxidants known as tannins that possess anti-infective, anti-inflammatory and anti-hemorrhagic properties.
