    What does it do?

    Have you ever thought if there is an easy way, other than a lab test, to tell whether our body might carry too much sugar? Probably not. Amazingly, back in the ancient time, Chinese doctors have already recognized the existence of high blood sugar levels with a simple test, that is, peeing on a rock to see if ants were attracted to feed on sweetness. Not only that, Chinese doctors also noticed thirst as an accompanying sign and thus named the symptoms together as Xiao Ke (wasting and thirsting) syndrome.

    From the perspective of TCM, most Xiao Ke cases manifest the characteristic of the deficiency of both Yin and Qi energies. For example, thirst is an outcome of Yin energy insuffiently balancing out Yang energy. That is as if not enough water cools out fire so the heat becomes excessive.

    Extensive studies have been carried out to understand the basis of glucose metabolism in the TCM term and many Chinese medicine have been developed. One common strategy emerges is to nourish Yin, tonify Qi, generate body fluids, and clear heat. GlucoAssure™ is our signature formula that follows the principle and may provide the dietary support to maintain blood sugar levels that are already in a normal range.

    Ren Shen (Ginseng root): As one of the most known Chinese herbs, Ginseng is a powerful Qi tonic. It tonifies Qi and generates fluids.

    Huang Qi (Astragalus root): Astragalus is also a very known Chinese herb that tonifies Qi and supports immune function.

    Fu Ling (Poria), Bai Zhu (Atractylodes rhizome) and Gan Cao (Licorice root): Poria, Atractylodes, and Licorice strengthen the digestive function and replenish Qi.

    Huang Jing (Solomon Seal rhizome): Solomon Seal tonifies the Kidneys, nourishes Yin, and moistens the Lung.

    Mai Dong (Ophiopogon tuber): Ophiopogon nourishes Yin, generates fluids, and quenches thirst.

    Ge Gen (Kudzu root, Pueraria root): Pueraria generates fluids and quenches thirst.

    Wu Wei Zi (Schisandra fruit): Schisandra fruits tonifies Kidneys, nourishes Qi, and generates fluids among other functions.

    Huang Lian (Coptis rhizome): Coptis clears heat and relieves toxicity.

    Da Huang (Rhubarb): Rhubarb also clears heat and relieves toxicity.

    Does research support GlucoAssure?

    Many Chinese herbs in GlucoAssure are shown in biomedical studies beneficial at regulating glucose metabolism. For example, a meta-analysis of clinical trials recently concluded that Ginseng may modestly yet significantly improve fasting blood glucose in people.1 From Astragalus, components like polysaccharides, saponins, and flavonoidshave have been isolated that may play various roles in immunoprotection, insulin resistance, and glucose metabolism.2 A water extract of Solomon Seal is shown to lower fasting blood glucose and glycosylated hemoglobin (GHb), and to improve the glucose tolerance in diabetic mice model.3

    Similarly, oligosaccharides of Ophiopogon may reduce fasting blood glucose level and improve oral glucose tolerance in diabetic rats.4 A dietary supplementation of kudzu root extract has been found to reduce fasting plasma glucose and improve insulin tolerance in obese mice.5 Berberine from Coptis may improve fasting blood glucose by directly inhibitiing gluconeogenesis in liver of diabetic rats.6

The dose may be doubled for a quicker and stronger response as needed (e. g., in an acute phase). Consult your practitioner for precise dosage recommendations based on body weight and other factors.

    Rated 5 out of 5 by from Energy, BG and weight are great! About 4 years ago I stared having issues with after meal blood spikes. I took hundreds of dollars worth of supplements leaving me fealing dependent, stuck with managing the symptoms and broke every month. I knew there was something out there for my particular condition. I tried Yinvive. It worked at lowering my blood sugar but I still had excessive hunger, thirst and put on about 10 lbs, thus my blood sugar came back up. I was afraid to to take GlucoAssure because I have always had a bad experience with licorice. But at this point I was willing to try anything. I started out at a small dose in the morning (less than have the dose recommendend) and was astonished at how well it curved my hunger, thirst and lethargy. I droppped off the 10 lbs and kept my blood sugar in the range I like to keep it. No negative side effects from the licorice.

    Product Q&A

    glucosasure is out of stock, but I am placing an order and want to know if I can include it, and have it on back order, so I won't have to pay a shipping fee. It seems I cannot do that on the website.
