Meet the secret behind the Okinawan Diet

Meet the secret behind the Okinawan Diet

Experts have agreed that one of the key factors leading to the longevity of the Okinawan population is the fact that their diet centers around fresh, colorful, nutrient-rich fruits and vegetables. And there’s one fruit in particular that’s been a staple in the Okinawan diet for hundreds of years. Bitter melon, or goya in traditional Okinawan, is a complex plant with a long tradition of use in both culinary and medicinal practices.

An ordinary plant with extraordinary health benefits

Medicinal use of bitter melon dates back to the 14th century, where it was used to help ease indigestion and stomach aches, as well as treat respiratory infections and skin wounds. In recent years it’s been the subject of hundreds of clinical studies, and research has shown it to contain at least 32 phytonutrients and bioactive compounds, many of which have been determined to have antidiabetic, antiviral, antibacterial, anti-inflammatory, and cholesterol lowering effects.

Why choose Goyamin?


We source our bitter melon from small, local Okinawan farms, we source our water directly from the melted snows of Mt. Fuji, and we use a specially developed, patented extraction process to ensure that the phytonutrients we obtain have the highest level of both potency and purity. Goyamin has been clinically tested and proven to decrease LDL cholesterol by an average of 4%.

Japan has more centenarians than anywhere else in the world, and there is now an increasing amount of evidence to suggest that a healthy diet is a significant factor in the number of people reaching this ripe old age.

Clinical trial

Clinically proven to lower LDL Cholesterol levels by 4%

Dyslipidemia, and especially high levels of low-density lipoprotein cholesterol (LDL-C), is a risk factor for cardiovascular disease and a target for related therapy. Several studies have suggested that bitter melon (Momordica charantia) improves lipid metabolism in animal models of dyslipidemia and diabetes. This study aimed to determine if a 30-day treatment using bitter melon extract could affect lipid metabolism in humans.​

Clinical trial methodology
This randomized, double-blind, placebo-controlled trial included 43 healthy adults 25 who received either 100 mg of bitter melon extract (n=23) or a placebo (n=20) in capsules three 26 times per day for 30 days. Weight, blood pressure, and levels of LDL-C and other blood 27 parameters were measured before and after the study period.


Results: Compared to the control group, the intervention group exhibited significantly lower LDL-C levels (P<0.01). There were no significant changes in either group in terms of body weight, body mass index, systolic pressure, diastolic pressure, total cholesterol, high-density lipoprotein cholesterol, triglycerides, or blood glucose.

Conclusions: Bitter melon extract in capsule form decreased LDL-C levels in humans.
