Japan Sun Chlorella®

A Brand you can trust

Since 1969, our mission has been simple: to bring the health supporting, nourishing nutrition of chlorella to as many people as possible.

Our founder, Mr. Hideo Nakayama, was suffering from post-World War II health complications. At only fifty-one years old, doctors gave him a few years to live. Mr. Nakayama had almost succumbed to his conditions until a friend introduced him to chlorella.

Full of gratitude, Mr. Nakayama decided to devote the rest of his life to the research and the spread of chlorella’s wonderful benefits to all over the world.

Sun Chlorella pioneered a unique process that pulverized chlorella’s tough outer cell wall, ensuring maximum digestibility and nutrients - a process that has made Sun Chlorella one of the most digestible chlorella on the market.

Today Sun Chlorella has been the leading premier chlorella brand winning prestigious awards for its quality and commitment to education and research. Our mission continues to be carried on all over the world. Sun Chlorella is family owned with Mr. Nakayama’s grandson, Mr. Futoshi Nakayama as the President of Sun Chlorella.

The immune system protects human's body from outside invaders, such as bacteria, viruses, fungi, and toxins (chemicals produced by microbes). It is made up of different organs, cells, and proteins that work together. Today's major health problems are the result of disorders with our cells. Healthy cell metabolism and renewal are dependent on proper nutritional balance and DNA and RNA. No vitamins or minerals can replace the value of whole foods.

Chlorella is a natural whole food that contains one of the highest natural sources of DNA and RNA, provides more than 20 different vitamins and minerals, fiber, an abundance of naturally occurring Beta Carotene (Provitamin A), B12 as well as 19 amino acids, including all of the essential amino and fatty acids(including omega 3). It is particularly rich in lysine which is often lacking in our diet.

Chlorella has been proven effective at removing heavy metals from the body in multiple animal studies. It has been found to weaken heavy metal toxicity in the liver, brain, and kidneys.

Active B12 is mostly found in animal products- however, chlorella has been proven to be one of the rare plant foods to contain active B12, which makes it an excellent food for vegans and vegetarians to prevent B12 deficiency.

In fact, chlorella is the richest source of chlorophyll, compared to any other plant food. Chlorella contains 20 times the chlorophyll of alfalfa, nearly 10 times of spirulina, 8 times that of wheat grass and 10 times that of barley grass.

What's more, each of Sun Chlorella's cells is a self sufficient organism with all of the plant's life function taking place inside the cell that results in an unusually high concentration of nutrients in the chlorella plant (sun chlorella is 60% protein compared to rice; 7%, and soybean; 39%).

Additionally, Sun chlorella contains a variety of minerals like iron and iodine as well as zinc. As a nutritionally balanced whole food, Sun chlorella is the perfect complement to any supplement.

Young again~ Chlorella Growth Factor

Chlorella contains a special substance called Chlorella Growth Factor (CGF), a unique nucleotide-peptide complex (DNA & RNA) which is called plant hormone. It can promote cell renewal, activate and repair damaged cells. C.G.F. can stimulate T cells, enhance the ability to fight viruses, effectively fight viruses, and resist aging. C.G.F. reduces the loss of collagen and strengthens proliferation. Therefore, it can keep the skin elastic and shiny. C.G.F. in Chlorella after wall breakage can increase the regeneration capacity of normal cells by more than 25%, produce better quality cells, and regenerate cells, tissues and organs. Therefore, it helps to strengthen the curative effect during illness and speed up recovery after illness.

CGF can only be found in the chlorella algae. Researchers have discovered that CGF is produced by chlorella during the intense photosynthesis that enables chlorella to grow so rapidly. In fact, it actually gives the chlorella cell the ability to quadruple itself every 20 to 24 hours, which explains why it has been on planet earth for over 540 million years.


There are many species of chlorella, and the C.G.F. content entirely varies depends on species and culture method. Chlorella pyrenoidosa has the largest amount of C.G.F. than other species and we only can found “Sporopollein” in this species. Sun Chlorella is using outdoor cultivation to culture Chlorella pyrenoidosa. The chlorella cultured outside under full exposure to sunlight has larger amount of C.G.F. than one cultured in tank from the aspect of culture method.

DYNO ®-MILL Process:

Chlorella’s cell wall has protected it for millions of years, allowing chlorella to flourish as one of the oldest forms of life still on earth. Numerous studies show that chlorella’s fibrous cell wall can bind to harmful elements, such as pesticides and heavy metals, and then safely remove them from the body. Sun Chlorella has a special patented process, called, "Dyno Mill" that breaks the cell wall naturally. Other brands use heat-treated processes, chemicals and enzymes which are less effective in breaking cell walls and end up damaging many of the important nutrients and resulting in an inferior product.

Sun Chlorella's special patented broken cell wall process ensures up to 90-95 percent absorbtion and digestion. This means you get more chlorella nutrition with Sun Chlorella than any other chlorella or green food product. And the broken cell wall provides a natural source of fiber - ideal for health-conscious individuals demanding whole foods that assist with the elimination of the body's waste and toxins, an important key to a clean and healthy colon.

Heavy Metal

Only Sun Chlorella can remove heavy metal

Everywhere we go toxic chemicals attacks us, even where we least expect them: the carpets we walk on, the shampoos and toothpastes we use, the pots we cook in and the dental fillings in our mouths. The sad truth is that modern life is an uncontrolled experiment in toxic bombardment.

Did you know that each of these toxins acts like a time-bomb, tick, tick, ticking, in the body until one day they explode and send your good health down the drain? Toxins are a cause of many healthy concerns. Lead in drinking shown to blood pressure, and trihalomethane found in public water supplies can compromise good bladder health. We all need protection from these damaging chemicals. Sun Chlorella does an outstanding job keeping our bodies clean.

“Nothing is a better detoxifier than Sun Chlorella. It safely eliminates toxic elements that have built up in your body. It revitalizes your cells and supports your body’s own natural detoxifying process.” Michael E. Rosenbaum, M.D, he is one of America’s most respected expects in natural healing.

Clinical studies show Sun Chlorella’s Remarkable Detoxifying Power

Clinical Research has documented chlorella’s ability to remove toxins stored in body tissues and to help stop new toxins from being absorbed.


A landmark study published in the Journal of Medicinal Food showed how chlorella reduced the dioxins in breast milk. “Dioxin” is the name generally given to a class of super-toxics chemicals. Their toxicity is second only to radioactive waste.


Studies at the school of Medicine, West Virginia University, demonstrated that chlorella helped remove poisonous poly-chlorinated by phenols (PCBs), (a major toxic pollutant found in pesticides and herbicides).


In other studies, chlorella was equally effective in eliminating heavy metals such as copper, and cadmium.


Reseach shows that chlorella effectively sweeps out mercury from the bowel and cells of the body.

The German medical community discovered that the cell membrane of Chlorella contains the special substance "Sporopollenin", but it only exists in the Chlorella Pyrenoidosa species. This substance not only has the function of confirming poisons, but also has the characteristics of combining with various toxins without reversing. It can excrete various toxins, heavy metals and stubborn substances from the body together to purify the body. Chlorella has been found to be the only one in the world to have its unique detox function towards Dioxin.
