Gingko biloba GK501 & Panax ginseng G115
Jump To:

The Ingredients

In Gincosan®, two specific standardised extracts from the roots of Panax ginseng C.A. Meyer and the leaves of Ginkgo biloba, have been combined to create a unique patented formulation of GK105 (ginkgo) and G115 (ginseng).

Discover more about the G115 and GK105 extracts used by SFI Health, how they work together, and the key studies that support their benefits when used in Gincosan.

Always read the label. Follow the directions for use. Contains lactose. 

Ginkgo biloba and Panax ginseng in history

Ginkgo biloba L. belongs to the family of Ginkgoaceae, and is believed to be the oldest living tree. Extracts and infusions from the leaves of Ginkgo have been used in history for thousands of years.

More about Ginkgo and Ginseng in history

Panax ginseng is a perennial shrub, native to north-eastern China, Korea and Russia. Panax ginseng was first recorded in Chinese medicine over 2000 years ago, and was already the subject of over 600 published books and papers before the year 2000.

The specific extract combination used by SFI Health: GK501 & G115

GK501 is the specific extract of Ginkgo biloba used in Gincosan. It is obtained from the dried leaves of the plant and is extracted and processed according to a similar principle as for G115. This ensures that the ‘standardised extract’ contains a consistent content of active ingredients; 24.5% ginkgoflavon glycosides and 6% terpenes (ginkgolides, bilobalide).

G115 is the specific extract of Panax ginseng used in Gincosan. Its first mention goes back to 1960, and it has over 35 years of research supporting it as an individual extract.9

More about the benefits of GK501 & G115

The extract G115 is produced from the roots of Panax ginseng C.A. Meyer. This is where most of the important ingredients lie, including the active ingredient – the ‘ginsenosides’. It takes up to five years, and involves multiple steps for a Panax ginseng root to become G115, ensuring that there is an optimal concentration of the active therapeutic components. Thanks to a complex process, the G115 extract in Ginsana®, contains a consistent content of ginsenosides – 4% to be exact.

Because the GK501 and G115 extracts are specific and standardized, it is possible to investigate their effects on cognitive function in clinical trials.

The beneficial effect of GK501 and G115 in Gincosan is based on numerous clinical trials in humans. Results from these clinical studies1-8 suggest that this patented combination can:

  • Support concentration
  • Improve mental alertness
  • Support healthy blood circulation
  • Maintain mental clarity
  • Enhance cognitive performance

How GK501 & G115 works

The physiology of cognitive performance is a complex process, so the use of a combination of extracts that can act in multiple ways can be useful to support the processes involved. G115 and GK501 are combined in Gincosan to help improve cognitive function.

More about how GK501 & G115 works

Gincosan does this by helping to:

  • support and maintain healthy blood circulation including to the peripheral areas of the body
  • maintain brain function by acting as an antioxidant: helping to reduce free radical formation and damage to body cells

GK105 and G115 in clinical trials

The specific extracts used in Gincosan – known as GK105 and G115 – have been researched together over 20 years, in more than 7 clinical trials1-8, with a demonstrated good tolerability profile.

SFI Health Difference

What makes Gincosan simply different?

Medicines with naturally sourced active ingredients can vary considerably depending on the species of plant chosen, the way it’s grown, harvested, and produced. Therefore, it’s essential to ensure the active ingredient in your product is the same type, and in the same quantity, as the one tested in clinical trials.

In Gincosan, we take care to use the same specific Ginkgo biloba and Panax ginseng extracts (combination of GK501 and G115) with the same specifications that have been researched in clinical studies to aid cognitive function and mental performance.1-6  That’s why you can be confident that Gincosan can offer the benefits demonstrated in the research.rocess with careful consideration and control at every stage of creation.
