Volumes of studies back Spirulina’s powerful health impact

Spirulina is well known as one of the richest sources of vitamins and minerals that nature has to offer. Now, it’s its potential therapeutic effects are backed by scores of studies and volumes of research.

Spirulina has been used for centuries to boost immunity and energy, support skin, eye and bone health and for overall good health and, Marcus Rohrer Spirulina has been proven to be among the purest and most nutrient rich Spirulina in the world.

Spirulina has been endorsed by the United Nations World Food Conference as “one of the best foods for the future¹”.

Widely dubbed as a “superfood”, Spirulina has also been declared by Nasa as en excellent, compact space food for astronauts².

The World Health Organisation has described Spirulina as a “very suitable food³” noting that it is rich in iron and protein and can be administered to children without any risk.

It is commonly accepted that Spirulina contains the most remarkable concentration of nutrients known in any plant?, notably:

      It comprises 60% vegetable and complete protein – vastly superior to other typical plant protein.
      Vitamins – it contains more carotenoids than any other wholefood.


  • It is the richest vegetable source of bioactive vitamin B12, vitamin K1 & K2 among others.
  • It contains 96 minerals and trace elements.
  • It is packed with chlorophyll.
  • It contains high levels of phycocyanin, a special phytonutrient and strong antioxidant.
  • It contains various enzymes including SOD.
  • It’s the richest natural source of gamma linolenic acid (GLA).

Three grams of Marcus Rohrer Spirulina provides?:

  • 10.000 IU of vitamin A (= 200 % RDA*)
  • 9 mcg of vitamin B12 (= 150 % RDA*)
  • 60 mcg of vitamin K (= 75 % RDA*)
  • 6,5 mg of iron (= 65 % RDA*)
  • 0,4 mg of manganese (= 20 %RDA*)

RDA = Recommended Daily Allowance (EFSA, European Food Safety Authority)


Studies have shown that Spiruilna is exceptionally nutrient dense.

Note the nutrient profile of Spirulina below vs other foods (compared per weight):

• 180% more calcium than whole milk

• 670% more protein than tofu

• 3100% more beta carotene than carrots

• 5100% more iron than spinach

• more antioxidant and anti-inflammatory activity in 3 g of Spirulina than in five servings of fruits and vegetables


In addition, Spriulina is easily digested and absorbed – it does not have a hard cell wall like other plants but a cellulose free, soft cell wall, making it easily digested and absorbed. This makes it suitable for people with a weak digestive system, poor absorption due to gut problems and the elderly and chronically ill.


It is also strongly alkalising, helping restore the body’s ph balance, and has an extremely high anti-oxidant capacity through the following:

  • Beta Carotene: carotenoid for skin, eyes, mucous membranes, immune system & safe source of vitamin A
  • Zeaxanthin: special carotenoid, fights free radical damage with specific benefits for eye health and brain health (crosses blood brain barrier)
  • Phycocyanin: photosynthetic pigment, strong antioxidant, promotes liver and kidney health, rarely found in foods
  • Super Oxide Dismutase (SOD): excellent free radical scavenger, helps to repair cells, slows down age related degeneration
  • Manganese: needed to form body own SOD
  • Tocopherols: (vit E) – B1 – B5 – B12 – zinc – selenium


The following are recognised potential therapeutic applications of Spirulina

  • Prevention of infections ???
  • Inhibition of HIV ¹??²²
  • Prevention of cancer ²³?²?
  • Prevention of cardiovascular disease²??³¹
  • Better management of type 2 diabetes³²
  • Prevention of neurodegenerative diseases ³³?³?
  • Prevention of Age Related Macular Disease³?
  • Prevention of liver disease and NASH³????
  • Anemia ?????
  • Allergies?????
  • Heavy metal removal – Prevention of kidney disease
