Spirulina is a blue-green algae from the genus Arthrospira (“arthro” roughly which means “joint,” and “spira” which means “spiral”). It has been utilized by the Aztecs in Mexico and by folks dwelling within the Lake Chad space in Africa for hundreds of years. Spirulina’s normally cultivated from our bodies of water like lakes or farmed in ponds.
Spirulina comprises a number of vitamins, together with fat-soluble nutritional vitamins (A, E, and Okay), fatty acids (DHA, EPA), beta carotene and minerals. It is also a supply of protein, however it lacks excessive sufficient ranges of a number of the amino acids that your physique must operate at its finest (except you’ve gotten a medical situation the place it’s essential to keep away from particular amino acids, like with phenylketonuria or “PKU”). Since spirulina comes from micro organism (particularly “cyanobacteria”), it could be thought of as a protein supply for vegans.
It is also necessary to notice that the B12 in spirulina is in a unique kind as “pseudovitamin B12” than the sort that is usually absorbable by your physique. You will doubtless must look elsewhere to your B12 wants, particularly in the event you observe a vegetarian or vegan manner of consuming which could be low in B12. Decrease ranges of B12 are additionally present in adults over the age of 60 years. And why’s B12 necessary? As a result of your physique wants B12 to make crimson blood cells and it is also essential for mind and nerve cell improvement. Not getting sufficient B12 may cause tiredness, reminiscence loss, despair, and even various kinds of anemia. However we digress.
This text takes a better have a look at the potential makes use of of spirulina. It additionally covers dangers related to its use.
Dietary dietary supplements aren’t regulated in the USA, which means the FDA doesn’t approve them for security and effectiveness earlier than merchandise are marketed. When potential, select a complement that has been examined by a trusted third occasion, equivalent to USP, ConsumerLabs, or NSF. Nevertheless, even when dietary supplements are third-party examined, that doesn’t imply that they’re essentially secure for all or efficient on the whole. You will need to speak to your healthcare supplier about any dietary supplements you intend to take and to test in about any potential interactions with different dietary supplements or drugs.

Makes use of of Spirulina
Complement use ought to be individualized and vetted by a healthcare skilled, equivalent to a registered dietitian nutritionist (RD/RDN), pharmacist, or physician. No complement is meant to deal with, remedy, or forestall a illness.
Spirulina has fat-soluble nutritional vitamins (like A, E and Okay), beta carotene and minerals, protein, and phycocyanins (pigments that produce a blue shade and which have proven antioxidant results). Phycocyanins have been used as a dye in lots of industries, together with pharmacy, culinary, and even cosmetics.
Scientists have studied – however not essentially confirmed – spirulina’s affect on completely different areas of well being, together with however not restricted to:
We’ll discover what the science says about spirulina’s effectiveness for these well being outcomes.
In keeping with a meta-analysis (a set of analysis research) of 9 research with a complete of 415 folks, spirulina elevated superoxide dismutase (SOD) and whole antioxidant capability (TAC). The research used wherever from one to eight grams of spirulina per day, a fairly large vary. Most of the research had a fairly small variety of folks in them, which means they won’t have the ability to inform us very a lot. The energy of the consequences weren’t earth-shattering, and had been usually stronger when folks took 5 grams of spirulina per day or extra.
The conclusion? Getting antioxidants from the meals that we eat might help cut back a number of the irritation in our our bodies. To amp up antioxidants in your weight loss plan, attempt together with a wide range of probably the most nutrient-dense meals which you could supply and afford – and so they do not must be natural – like entire grains, fruit, and greens to assist improve your physique’s antioxidant capability and to scale back irritation in your physique. Simply do not depend on spirulina alone.
Scientists did a meta-analysis (a set of a number of analysis research on a subject) of 5 randomized managed trials that included 230 folks to test spirulina’s results on blood strain. The folks within the completely different research took wherever from one to eight grams a day of spirulina (a fairly large vary). The lengths of the research had been wherever from two to 12 weeks. And lots of the research had been fairly small, which means they actually may not have the ability to inform us very a lot.
When the information was “pooled” (put collectively) and analyzed from these research, the scientists stated that the spirulina lowered systolic blood strain by about 4.59 mmHg and in addition diastolic blood strain by 7.02 mmHg. Systolic strain (prime quantity) measures the strain in your arteries when your coronary heart beats. Diastolic strain (backside quantity) measures the strain your arteries expertise between every coronary heart beat. The largest blood pressure-lowering within the research was seen in individuals who had hypertension already. Is smart.
The scientists additionally stated extra, prime quality research are wanted earlier than we will begin recommending that everybody with hypertension wants to begin consuming spirulina. Honest sufficient. Subsequent!
Blood sugar management
Have you ever ever gotten a jittery feeling after consuming a number of sugary meals? That normally means your blood sugar’s spiking. And this example could be notably severe for folks dealing with situations like sort I or sort II diabetes, disordered consuming together with diabulimia, and extra.
Over time, blood sugar spikes which are left uncontrolled can truly result in injury to your physique. Worst case, in sure situations like diabetes, that may seem like having to surgically take away elements of your physique (amputation), coronary heart assaults, kidney failure, or stroke which may result in paralysis of elements of your physique. Whereas spirulina actually would unlikely have the ability to the proper extreme injury from uncontrolled blood sugar over time by itself, it has lowered blood sugar ranges in human research. And why? It might be its protein and fiber content material, or maybe it’s phycocyanin’s means to assist with irritation. Scientists are nonetheless figuring it out.
Fourteen research with 510 folks with metabolic syndrome – a set of signs like excessive blood sugar, hypertension, excessive triglycerides, low HDL (“good ldl cholesterol”), and excessive waist circumference which all collectively can create extra severe well being issues – had been included in a meta-analysis of spirulina’s results on blood sugar and different outcomes. And a number of these research did not have many individuals in them (they’d “decrease statistical energy”). Individuals took wherever from one to eight grams of spirulina per day (once more, that is a fairly large vary). Blood sugar and insulin ranges had been decreased in a number of the research after taking particular quantities of spirulina. Extra, prime quality research are wanted earlier than we will suggest spirulina for decreasing blood sugar and insulin ranges.
Usually, working with a crew that features a registered dietitian nutritionist (RD or RDN) – and notably one which’s a Licensed Diabetes Care and Schooling Specialist (CDCES) – might help you discover your consuming, motion, treatment habits and extra. RDs/RDNs might help you construct your toolkit and your capability to keep away from spikes in your blood sugar. That might provide help to really feel higher. Managing blood sugar could be difficult and we do not have to do it alone!
Sorry of us, there’re only a few, well-conducted human research which have checked out spirulina’s results on most cancers. There’ve been a number of research in check tube cells or in animals that are not people. Whereas that is actually attention-grabbing “preliminary” info (a spot to begin), if there aren’t well-constructed research its results in people, we won’t actually make any assumptions about its results on our species.
Levels of cholesterol
Scientists carried out a meta-analysis of spirulina’s results on levels of cholesterol that had seven managed trials for a complete of 522 whole folks. They discovered that spirulina decreased: whole ldl cholesterol (by 46.76 mg/dL), low density lipoprotein (“LDL” by 41.32 mg/dL), and triglycerides (by 44.23 mg/dL). It additionally elevated the “good” ldl cholesterol or excessive density lipoprotein (“HDL” by 6.06 mg/dL). Once more, why did spirulina do that? We’re unsure, however scientists assume it could be resulting from its dietary profile (fiber, fatty acids like DHA and EPA), its antioxidant capability, or a mixture of those.
Whereas we won’t suggest spirulina for decreasing your ldl cholesterol, we will counsel working with a crew that features a registered dietitian nutritionist (RD or RDN) that may provide help to discover your patterns of consuming, motion and extra. Registered dietitian nutritionists might help you construct your toolkit and your capability. Once more, you are not alone!
Liver well being
Spirulina has been studied for its results on liver well being in folks with nonalcoholic fatty liver illness (NAFLD). The research, nonetheless, was very small (solely 13 folks) so we actually cannot draw any conclusions about spirulina for NAFLD till bigger and higher research are carried out.
Scientists have studied spirulina’s results on metabolic syndrome. Metabolic syndrome occurs when you’ve gotten hypertension, excessive blood sugar, excessive ldl cholesterol, and extra fats round your waist (extra stomach fats). Metabolic syndrome can wreak havoc along with your well being, and will increase your odds of getting a coronary heart assault, stroke, and sort two diabetes. One in every of metabolic syndrome’s primary causes is considered weight problems. Weight problems, nonetheless, may also be related to a number of different social, financial, and environmental causes (aka, “determinants of well being”). Moreover, its definition relies on a metric that is considered flawed (Physique Mass Index, or BMI). It is necessary to notice that BMI doesn’t essentially consider necessary physique composition components like body dimension and muscle mass.
One spirulina meta-analysis pulled collectively knowledge from 18 research. It steered that spirulina may assist with decreasing hypertension, excessive blood sugar, and excessive ldl cholesterol – all elements of metabolic syndrome. It is necessary to notice that whereas spirulina might have an effect on these outcomes, a very powerful challenge can be working in your present manner of consuming, your motion (train), and different equally necessary points like addressing your emotional well being. Spirulina cannot remedy all of those severe points by itself.
Think about working with a crew that features a registered dietitian nutritionist (RD or RDN) – and maybe one which’s a Board Licensed Specialist in Weight problems and Weight Administration (CSOWM). RDs/RDNs might help you discover your consuming, motion, treatment habits and extra. They might help you construct your toolkit and your capability that can assist you really feel higher. Typically it may be difficult to provide your self permission to ask for and settle for assist. However you’ve got received this. And you do not have to go at it alone.
In a meta-analysis of 5 research, scientists checked out spirulina’s results on weight administration in folks dealing with weight problems. Whereas spirulina did lower weight in folks with weight problems by 4.55 kilos (2.06 Kg) and in individuals who had been chubby by 2.82 kilos (1.28 kg), clinically talking, this isn’t sufficient to make a stable advice to be used of spirulina for weight problems remedy.
As talked about beforehand, it is necessary to notice that weight problems may also be related to a number of different social, financial, and environmental causes (aka, “determinants of well being”). Moreover, its definition relies on a metric that is considered flawed (Physique Mass Index, or BMI). It is necessary to notice that BMI doesn’t essentially consider necessary physique composition components like body dimension and muscle mass. And BMI undoubtedly doesn’t give the total image of a person’s wellbeing. Think about requesting a physique composition check (for instance, skin-fold measurements, or a DEXA Physique Composition scan) out of your healthcare supplier along with different parameters that they could measure.
As talked about above, think about working with a crew that features a registered dietitian nutritionist (RD or RDN) – and ideally one which’s a Board Licensed Specialist in Weight problems and Weight Administration (CSOWM). CSOWM RDs/RDNs might help you discover your consuming, motion, treatment habits and extra. They might help you construct your toolkit, your capability, and provide help to really feel higher. You have received this.
