For decades it has been called the food of the future, and <strong>spirulina benefits<\/strong> are claimed for energy, immunity, weight loss and cholesterol. Many of these promises go further than the evidence. Here are 7 science-based facts about spirulina benefits, its research and its safety.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Protein_A_High_Percentage_but_a_Small_Amount\"><\/span>1. Protein: A High Percentage but a Small Amount<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Protein makes up more than half the weight of dried spirulina, which is why it is so famous. But a level teaspoon weighs 3.3 g and provides only 2 g of protein, roughly a third of an egg. A high percentage does not mean a large amount, and it will not cover the protein needs of an athlete or a vegan. This is the first thing to understand about spirulina benefits.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Spirulina_Benefits_From_Iron_and_GLA\"><\/span>2. Spirulina Benefits From Iron and GLA<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One teaspoon provides 1.6 mg of iron, about 8% of the daily value. That is a helpful contribution but not a treatment for anaemia. Anyone with confirmed iron deficiency needs a proper iron supplement at a dose set by a doctor; read about <a href=\"https:\/\/nostylelike.net\/en\/iron-bisglycinate\/\">iron bisglycinate<\/a>. Spirulina also naturally contains gamma-linolenic acid (GLA), an omega-6 fatty acid, but in small amounts.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Spirulina_Benefits_in_the_Studies\"><\/span>3. Spirulina Benefits in the Studies<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Blood lipids:<\/strong> small trials, some pooled in reviews, found moderate drops in LDL cholesterol and triglycerides, but study quality varies.<\/li>\n<li><strong>Blood sugar:<\/strong> a few studies in people with type 2 diabetes showed slight improvements, which do not replace medication.<\/li>\n<li><strong>Weight and seasonal allergies:<\/strong> limited data and inconclusive results.<\/li>\n<\/ul>\n<p>So spirulina benefits for lipids and blood sugar are possible, but larger and longer trials are needed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"4_Spirulina_Benefits_and_the_Vitamin_B12_Myth\"><\/span>4. Spirulina Benefits and the Vitamin B12 Myth<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spirulina contains compounds that resemble vitamin B12, called pseudo-B12 or B12 analogues. They are inactive in the human body and can even make a blood test look falsely reassuring. Vegans and vegetarians should not rely on spirulina for this vitamin; they need fortified foods or a real B12 supplement.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Who_Should_Avoid_Spirulina\"><\/span>5. Who Should Avoid Spirulina?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Phenylketonuria (PKU):<\/strong> spirulina contains phenylalanine, so people with PKU must avoid it completely.<\/li>\n<li><strong>Autoimmune diseases:<\/strong> such as lupus, multiple sclerosis and rheumatoid arthritis, because spirulina may stimulate the immune system; ask your doctor first.<\/li>\n<li><strong>Immunosuppressant medicines:<\/strong> after an organ transplant or for autoimmune disease, check with your doctor.<\/li>\n<li><strong>Pregnancy, breastfeeding and children:<\/strong> only on a doctor&#8217;s advice.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"6_Contamination_Risk_and_Why_Quality_Matters\"><\/span>6. Contamination Risk and Why Quality Matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spirulina harvested from polluted water can carry toxins called microcystins, made by other algae, or heavy metals, and these can harm the liver. Buy only tested spirulina from a well-known company and avoid powders of unknown origin; contamination can cancel spirulina benefits and turn them into harm. The product we stock is USDA certified organic.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"7_How_to_Take_It\"><\/span>7.
