Are you getting your 9 servings of fruits and vegetables a day, as recommended by doctors? Who is, right? By taking our all-natural Earthrise Spirulina Natural every day, you will get your recommended intake of protein, beta carotene, vitamins, and minerals all in one dose. That's why it's called a natural superfood powder. Earthrise's California-grown spirulina is one of the most nutrient-dense foods on the planet; here is why: This spirulina powder has more iron and phytonutrient levels than spinach and blueberries, more beta carotene than carrots, more calcium than whole milk, and more protein than tofu. Just 3 grams of spirulina powder has more antioxidant activity than 4 servings of fruits and vegetables. Scientific studies show Spirulina protects the heart and brain from oxidative stress while supporting a healthy immune system. This green superfood powder promotes immune health and protects the heart and brain from oxidative stress through powerful antioxidant protection. And with its high beta-carotene content, it promotes eye health too. (take from the Earthrise website) We have been producing and cultivating our spirulina since 1976.
