Ginseng (Panax ginseng C.A. Meyer) has been used for millennia in traditional Korean medicine for its tonic and adaptogenic properties. However, unprocessed classic ginseng has a major drawback: its actives, the ginsenosides, are large molecules the body absorbs with difficulty. To address this, IL HWA developed the Ginst15 process. Whole mature red Korean ginseng roots, grown for six years under controlled conditions, are first extracted using a traditional aqueous process, then fermented by specific enzymes and microorganisms over a precisely calibrated duration. The result is a concentrated extract whose ginsenoside profile has been radically transformed: the large ginsenosides are converted into directly assimilable active metabolites, then packaged into individual soluble tea sachets, each containing the recommended daily dose.

Research conducted by IL HWA and independent laboratories shows that the bioavailability of Ginst15’s ginsenosides is significantly higher than that of an unfermented ginseng extract. Fermentation increases the concentration of Compound K, a metabolite normally produced only in small quantities by the gut flora when digesting classic ginseng. With Ginst15, the body receives these active metabolites directly, which explains the rapid results reported by many users.

Several ginseng species exist worldwide (American, Siberian, Japanese), but Korean Panax ginseng is considered the richest in ginsenosides and the most scientifically studied. South Korea’s soil and climate conditions, combined with centuries of ginseng-growing tradition, produce roots of exceptional quality. IL HWA uses exclusively Korean ginseng for Ginst15.

Ginseng is classed among the adaptogenic plants — it is traditionally understood to help support the body’s capacity to adapt to different forms of stress, whether physical, mental or environmental. Ginst15’s optimised bioavailability allows for full benefit from these adaptogenic properties. For energy and vitality, fermented ginseng offers daily support for tired, overworked or convalescent people. Unlike classic stimulants such as caffeine, ginseng works more deeply on cellular energy mechanisms without causing an excitement spike followed by a crash — its action is gradual and sustained, making it well suited to long-term use. Fermented ginseng is also traditionally associated with supporting the body’s immune defences, and with maintaining cognitive capacities — concentration, memory and mental clarity — particularly during exam periods, intense intellectual work, or simply to accompany natural cognitive ageing.

Dissolve 1 sachet a day in a cup of hot or cold water, as preferred. Ginst15 has a characteristic ginseng taste, slightly bitter and earthy, with a sweet note from fermentation. Best consumed in the morning or early afternoon to avoid disrupting sleep in sensitive individuals. A 1-3 month course is recommended for optimal results, renewable after a break of a few weeks. Ginst15 combines well with other adaptogens such as ashwagandha, rhodiola or reishi.

Do not exceed the recommended daily dose. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children. If in doubt, consult a healthcare professional.

What is the difference between classic ginseng and fermented Ginst15?

The main difference lies in the bioavailability of the actives. Classic ginseng contains large ginsenosides that the body must transform before use, a process that’s often incomplete. Ginst15 undergoes patented fermentation that carries out this transformation beforehand, delivering active metabolites like Compound K directly, for significantly higher absorption and effectiveness.

Does Ginst15 contain caffeine?

No, Ginst15 contains no caffeine. Although presented as a tea to dissolve, it is a fermented ginseng extract rather than a classic tea from Camellia sinensis. Ginst15’s energising effect comes exclusively from ginsenosides and their metabolites, without the side effects associated with caffeine (jitteriness, palpitations, tolerance build-up).
