Japan Algae Spirulina — 8 g a Day, and the Honest Version of What That Gives You Overview Spirulina is a filamentous cyanobacterium — a blue-green microalga in everyday language — grown in alkaline water and dried into a dense green powder that is then pressed into tablets. It is genuinely nutrient-dense: roughly 55 to 65 per cent protein by weight, with iron, carotenoids, gamma-linolenic acid and the blue pigment phycocyanin. That density is why it turns up in every 'superfood' list published since the 1970s.This is the Japanese-grown version in tablet form: 2,400 tablets of 200 mg, which at the manufacturer's full daily amount of 40 tablets works out at 8 g a day and 60 days per pack.One thing has to be said before anything else, because it is the single most common reason people buy spirulina and the single most common way it lets them down: the B12 in spirulina is not the B12 your body can use. If you are vegan and buying this as your B12 source, please read that section below before you order.Browse more from the same shelf: Japanese supplements, Japanese mineral supplements, Japanese vitamin supplements, Japanese health products.

Not verified against manufacturer data, so not stated here Sold by Tsujimoto Market, Kobe, Japan Who Is This For? Adults who want a whole-food source of plant protein, iron and carotenoids rather than isolated vitamins Vegans and vegetarians — with the B12 caveat below understood, not skipped People who would rather swallow tablets than deal with the taste of spirulina powder NOT for you if you have phenylketonuria: spirulina is protein-dense and therefore phenylalanine-dense NOT for you if you have an autoimmune condition, take an immunosuppressant, have gout or high uric acid, or have haemochromatosis or another iron-overload condition How to Use Start at 5 tablets a day for the first week, as the manufacturer suggests. Build up gradually towards 20–40 tablets a day, split across two or three servings. Take them with plenty of water, with or after food. Do not add spirulina to anything hot — heat degrades the pigments the tablets are valued for. If you take a prescribed medicine, leave at least two hours between it and the tablets: 8 g of algal matter is a real meal's worth of fibre and minerals. Frequency: Daily, split into 2–3 servings. Full amount is 40 tablets; build up to it, do not start there. Full Ingredients Ingredients: spirulina (Arthrospira platensis). That is the entire list — no binder, filler, sweetener or coating is declared.Declared per 8 g daily amount: spirulina 8,000 mg, of which protein 4.5 g; chlorophyll approximately 180 mg; iron; carotenoids; gamma-linolenic acid; and a vitamin B12 fraction.About that B12 fraction. Spirulina does contain corrinoid compounds that a laboratory assay will read as vitamin B12. The great majority of them are pseudo-B12: analogues that human B12 metabolism cannot use, and which may compete with real B12 for absorption. Spirulina is therefore not a reliable B12 source for anyone on a vegan diet. If you need B12, take a cyanocobalamin or methylcobalamin supplement, or ask your doctor for a blood test. We would rather lose the sale than have you find this out from a blood result.Composition as declared by the manufacturer. Always read the panel printed on the pack you receive. Cautions Phenylketonuria: do not take this. Spirulina is around 60 per cent protein, so 8 g a day is a meaningful phenylalanine load. Autoimmune conditions and immunosuppressant therapy. Spirulina has immune-stimulating activity in laboratory work. If you have an autoimmune diagnosis or take a drug that deliberately suppresses immunity, this is a conversation for your specialist before you order. Gout or raised uric acid. Spirulina is high in purines, which the body converts to uric acid. Iron-overload conditions such as haemochromatosis. Spirulina supplies iron, and 8 g a day supplies it repeatedly. Anyone on warfarin or another vitamin-K-sensitive anticoagulant should ask their doctor first — green algae carry vitamin K. The full daily amount is 40 tablets. That is a real pill burden, and a realistic reason to stay at a lower amount if swallowing tablets is difficult for you. Green stools and darker urine are expected with spirulina at this dose and are not a cause for alarm; digestive upset in the first week is common and usually settles if you build up more slowly. Stop taking it and consult a doctor if you develop stomach upset, rash, unusual tiredness, muscle pain or dark urine. If you are pregnant, breastfeeding, taking any prescribed medication or under medical care, ask your doctor before starting this supplement. Do not exceed the stated daily amount. More is not better with any of these ingredients. Store in a cool, dry place away from direct sunlight. Keep out of reach of children. This is a food supplement, not a medicine. It is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for prescribed treatment.

No, and this is the most important sentence on the page. The B12-like compounds in spirulina are overwhelmingly corrinoid analogues — pseudo-B12 — which human B12 metabolism cannot use and which may even compete with real B12 for uptake. A laboratory assay will report them as B12, which is how the myth survives. If you are vegan, use a cyanocobalamin or methylcobalamin supplement for B12 and treat spirulina as a protein and mineral food, which is what it is. Does spirulina detox heavy metals? We are not going to say that it does. Spirulina is widely marketed as "cleansing heavy metals from the body"; that is not a claim we will repeat. What is fair to say is that spirulina is a food, that the human body clears metals through the liver and kidneys, and that if you have a genuine concern about metal exposure the right step is a doctor and a test, not a supplement bought online. Forty tablets a day sounds like a lot. Is that really necessary? It is the manufacturer's full amount, and it is a lot — that is why the manufacturer itself starts you at five and tells you to build. Many people settle at 20 tablets rather than 40 and are perfectly content there. Nothing in the product requires you to reach the top of the range, and if swallowing tablets is difficult for you, a smaller daily amount taken consistently beats a large one abandoned in week two. Is Japanese spirulina safer than cheaper spirulina? It is produced under Japanese food-hygiene rules, which is a real difference from unregulated pond-grown material — the documented risks with poorly sourced spirulina are microcystin contamination from co-growing cyanobacteria and heavy-metal uptake from the growing water. What we cannot do is show you a batch certificate we have not seen. We can tell you the origin and let you weigh it. Why do my stools turn green? Because you are eating eight grams of concentrated chlorophyll a day. It is harmless and it stops when you stop. Digestive upset during the first week is also common — it is usually a sign you increased the amount faster than your gut wanted, and going back a step for a few days generally fixes it. Show more
