Spirulina and Chlorella are considered to be two of the most potent green superfoods on the market today – containing a plethora of proteins, vitamins and minerals that are not readily available in a plant-based diet. Onnit’s Spirulina and Chlorella pills are the ideal way to inject some of these much-needed nutrients into your daily diet, without having to consume tons and tons of green vegetables. They also form a vital part of Onnit’s Total Human complete vitamin supplement pack – appearing in both the Day and Night packs and guaranteeing that your body gets all the vital proteins, minerals and vitamins that it needs, when it needs them.

What really sets Spirulina and Chlorella out from the ‘superfood crowd’ is the efficiency with which they give our bodies the nutrients that they need – with a single gram of them estimated by some experts to deliver, up to 1000-times more nutrients than a serving of average fruit and vegetables. To put this in context, this means that a 1 gram serving of Onnit’s Spirulina and Chlorella has the potential to be equivalent to a kilogram of normal fruits and vegetables. It is also almost impossible to consume Spirulina and Chlorella within a traditional diet – as they are blue/green algae, a food category that humans tend not to eat.

Furthermore, Spirulina and Chlorella, are also one of the most environmentally friendly foods on offer – with a recent study by the University of Oxford, suggesting that they were the most ecologically efficient way of producing protein for human consumption. Unlike, vast herds of cattle that pump unfriendly greenhouse gasses into our atmosphere, Spirulina and Chlorella, require the least amount of land to produce a unit of protein that is ready for human consumption. This all adds up to an incontestable argument in favour of Onnit’s Spirulina and Chlorella supplement – they have a very high micro-nutritional value, are good for the planet as a whole and also provide a large range of nutrients that we need during our daily lives.

If you are looking for a high-quality green supplement, then Onnit’s Spirulina and Chlorella is the one for you. It works well as a standalone product, however, many people find that the results are better, when it is used as a part of Onnit’s Total Human complete vitamin supplement packs – a complex blend of nutrients that give your body the things it needs when it needs them. Whatever route you choose, don’t miss out on the chance to add this amazing green superfood into your diet!

Onnit’s Spirulina and Chlorella Ingredients

Onnit’s Spirulina and Chlorella capsules are an organic source of a variety of vitamins, minerals and proteins that have undergone limited processing. Chlorella has a rigid cell wall that our bodies are unable to break down by themselves, meaning that to gain the many nutritional benefits that it offers, this cell wall must be broken. Apart from that, Onnit’s Spirulina and Chlorella are totally organic, making them a great addition to a healthy and balanced diet.

Organic Spirulina (whole) – Spirulina is a blue-green alga that rose to fame, after it was successfully used by NASA as a dietary supplement for astronauts in space (P. D. Karkos, 2011), before this it was consumed by Aztec tribes for many centuries. There are numerous unsubstantiated health claims made about Spirulina, including that it can aid our metabolisms, help our cardiovascular systems, aid in weight loss, help diabetes and reduce cholesterol. With others saying that it has the potential to reduce stress, depression and ADHD. However, what cannot be questioned is its incredible nutritional value, with it known to contain large amounts of calcium, niacin, potassium, magnesium, B vitamins and iron (Gutiérrez-Salmeán, 2015). It also contains a large number of essential amino acids that out bodies cannot synthesise naturally, and studies have shown that proteins make up to 70% of its dry weight (Gutiérrez-Salmeán, 2015). Although science has not yet been able to either confirm or disprove the health benefits of Spirulina, its nutritional benefits cannot be questioned – providing our bodies with a plethora of the things that it needs to survive and thrive. Onnit’s Spirulina and Chlorella Capsules contain organic spirulina, allowing you to enjoy the many amazing nutritional benefits that it offers. It can also be taken as part of Onnit’s Total Human complete vitamin supplement pack – an innovative blend of nutrients that gives your body what it needs, at the times that it needs it.

Organic Chlorella

(whole, broken cell wall)

Chlorella is a single-celled alga that is found in Taiwan and Japan, which is renowned for its high nutritional value. Chlorella has a tough cell wall that is indigestible in its natural form (Guangwen Tang, 2011) – meaning that it has to be processed and the cell wall broken before it is possible to gain the many amazing nutrients that it contains. Scientific analysis of Chlorella has shown that in contains many essential amino acids, vitamin B12, iron and is around 60% protein, making it an excellent nutritional source of the vitamins, minerals and proteins that our bodies need to survive and thrive.

There have also been several studies into various the various health benefits of Chlorella and it has been demonstrated to improve the immune systems of lab mice (K Tanaka). Similar studies have been conducted on humans, with the results suggesting that chlorella may also boost the human immune system, although the academics who carried out the research felt more was required before they could state it with certainty. All of this and more ensures that Onnit’s Spirulina and Chlorella capsules are an excellent addition to any healthy diet and work even better when used as part of the Onnit Total Human complete supplement pack.

Environmental Sustainability

Spirulina and Chlorella are also one of the most efficient ways to produce protein (TUOMISTO) – a profound problem that our planet is likely to face in the 21st century. Many traditional protein sources, such as livestock, require oxygen, which they then replace with large amounts of greenhouse gasses that they pump into the atmosphere. As plants, Spirulina and Chlorella, utilise carbon dioxide during photosynthesis, meaning that they reduce the amount of carbon in our atmosphere. This coupled with the fact that they need less land and energy to produce protein, than livestock, (TUOMISTO) – ensures that they are one of the more environmentally friendly sources of protein that it is currently available. This makes Onnit’s Spirulina and Chlorella capsules an excellent choice for anyone who wants to consume protein from more environmentally friendly sources.

A Space age superfood?

If I were going to Mars, Spirulina and Chlorella would be at the top of the list of foods I would bring.” – Onnit’s founder, Aubrey Marcus, suggests that Spirulina and Chlorella would be at the very top of the list of foods that he would take to Mars, due to their high nutritional content and their simplicity. He is not alone in this opinion and spirulina became famous, when NASA utilised it as a supplement for astronauts (P. D. Karkos, 2011). Clearly, we are only just beginning to investigate the full benefits of these incredible algae – but the evidence all points to them being some of the most nutritional foods that it is impossible to consume. Onnit’s Spirulina and Chlorella capsules are the ideal way to enjoy the many nutritional benefits that they have to offer, although many people get better results, when used in conjunction with other supplements as a part of Onnit’s Total Human Complete Supplement Pack. Whatever way you choose to use them, don’t miss out on the chance to utilise these incredible superfoods!
