Although it is now cultivated in many Asian countries, it is widely acknowledged that the best and most effective jiaogulan grows in the forests and foothills of its original home in China.

The exact amount of jiaogulan, or of the other supernutrients contained in Jule, is not disclosed. This is considered one of the company's greatest intellectual assets. However, rest assured that each serving contains a highly efficacious amount of active ingredients specifically formulated to deliver maximum nutritional benefits.

Saponins are a diverse group of chemicals found throughout the plant kingdom, and many have been studied for their health benefits. Jiaogulan contains an elite subgroup of saponins called gypenosides, which may prove to exert the most profound influence on human health. Their structure is similar to the chemical structure of key hormones, and although gypenosides do not function as hormones, they have a remarkable ability to influence the body to produce a healthy balance of its own hormones. Jiaogulan contains more saponins than any other plant, and its bioactive gypenosides are not found in any other species.

No. It is not the purpose of a natural product such as Jule to treat, cure, or prevent disease; the FDA only approves drugs to offer these benefits.

There is no official approval process or certificate issued by the FDA to approve the sale of any food or dietary supplement. The Food and Drug Administration has established stringent regulations, called Good Manufacturing Practices (GMP), to ensure the safety and manufacturing of foods sold in the United States. Jule is manufactured in a GMP-compliant facility.

Jule is guaranteed to be fully potent for two years from the manufacturing date when kept unopened under cool and dry conditions. Product must be refrigerated upon opening and should be used within 30 days of opening.

Jule is extremely safe and jiaogulan has been consumed in Asia for thousands of years. However, if you are pregnant or nursing, please seek out the advice of a nutritionally oriented medical practitioner before using

The daily dosage is flexible, depending upon one’s needs. We recommend starting with 1-2 ounces twice daily. The bioactive gypenoside saponins have a slightly bitter flavor, which is balanced out by Jiaogulan’s natural flavor system. Because of this, some people may prefer to mix Jule with the beverage of their choice. This is perfectly fine and all the benefits of Jule can still be enjoyed.

Yes, children of all ages can enjoy Jule, but the dosage can be reduced to ½-1 ounce once to twice daily for children under age 15.

Jule is manufactured under Federal Good Manufacturing Practices at an FDA-compliant facility in the United States from highest-quality ingredients that are sourced from reputable vendors around the world.

As the name suggests, plants known as adaptogens help the body to adapt. Whether it’s to physical, emotional, or chemical stresses, these special herbs help your body cope better, allowing it to return to a state of balance (homeostasis). Adaptogens also help to maintain the strength and immune resistance of the entire organism.

Antioxidants are nutrients that protect the cells in your body from oxidative damage. As the body uses oxygen, there are by-products known as "free radicals" that can cause damage to cells. Antioxidants are known to denature these free radicals, and high antioxidant status in the body is associated with a decreased risk of many chronic diseases. Many fruits and vegetables have high antioxidant capacity, and Jule is outstanding in this regard. It provides the antioxidant capacity of 15 servings of fruits and vegetables in just 4 ounces.

Preservatives help maintain a product’s freshness. Sodium benzoate, the sodium salt of benzoic acid, can prevent the growth of almost all microorganisms (e.g., yeast, bacteria, and fungi). Benzoic acid is found naturally in tea, anise, most berries, cultured dairy products and cheese, cherry bark, and cassia bark. As a result of extensive safety data and long years of widespread use, the United States government has determined sodium benzoate to be generally recognized as safe (GRAS). Jule contains less than one-tenth of one percent sodium benzoate, which is just the right amount to keep harmful microbes from growing.

Potassium sorbate is a potassium salt version of sorbic acid, a polyunsaturated fat used to inhibit mold growth. Sorbic acid has been repeatedly tested for safety and efficacy, and today stands as one of the most thoroughly tested food additives in history.

People in China have been drinking herbal tonics and remedies for generations, but for those outside of Asia, they may be an “acquired taste.” High-quality jiaogulan is somewhat bitter by nature so Jule is blended together with a small amount of organic cane juice, natural fruit juice, and natural flavor. Some people may prefer to mix Jule with the beverage of their choice. This is perfectly fine and all the benefits of Jule can still be enjoyed.
