ABSTRACT: Epigallocatechin-3-gallate (EGCG), a component extracted from green tea, has been proved to have multiple effects on human pathological and physiological processes, and its mechanisms are discrepant in cancer, vascularity, bone regeneration, and nervous system. This review focuses on effects of EGCG, including anti-cancer, antioxidant, anti-inflammatory, anticollagenase, and antifibrosis effects, to express the potential of EGCG and necessity of further studies in this field.
- Kishimoto Y et al. Pleiotropic preventive effects of dietary polyphenols in cardiovascular diseases. European Journal of Clinical Nutrition, vol. 67, no. 5, pp. 532–535, 2013. ABSTRACT: The purpose of this study was to review recent findings highlighting daily dietary polyphenol intake and the diverse function of polyphenols and their possible relationships to cardiovascular disease (CVD). their previous findings provide that Japanese people intake polyphenols mainly from beverages, especially coffee and green tea (in descending order of polyphenol content). Many kinds of polyphenols act as an antioxidant against low-density lipoprotein oxidation, which is known to promote atherosclerosis. Recent accumulating evidence suggests that dietary polyphenols could exert their cardioprotective actions through their potential to improve metabolic disorder and vascular inflammation. These findings raise the possibility that polyphenols have a wide variety of roles in the intestine, liver and vascular tissue.
- Qian Yi Eng et al. Molecular understanding of Epigallocatechin gallate (EGCG) in cardiovascular and metabolic diseases. Journal of Ethnopharmacology, Volume 210, 10 January, 2018, pp. 296-310. ABSTRACT: EGCG was found to exhibit a wide range of therapeutic properties including anti-atherosclerosis, anti-cardiac hypertrophy, anti-myocardial infarction, anti-diabetes, anti-inflammatory and antioxidant. These therapeutic effects are mainly associated with the inhibition of LDL cholesterol (anti-atherosclerosis), inhibition of NF-κB (anti-cardiac hypertrophy), inhibition of MPO activity (anti-myocardial infarction), reduction in plasma glucose and glycated haemoglobin level (anti-diabetes), reduction of inflammatory markers (anti-inflammatory) and the inhibition of ROS generation (antioxidant).
- Xu Y et al. Inhibition of Tobacco-specific Nitrosamine-induced Lung Tumorigenesis in A/J Mice by Green Tea and Its Major Polyphenol as Antioxidants. Cancer Research, Published July 1992. ABSTRACT: This study examined the effects of green tea and its major components, (-)-epigallocatechin gallate (EGCG) and caffeine, on the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced lung tumorigenesis in A/J mice. They also studied the effects of green tea and EGCG on O6-methylguanine and 8-hydroxydeoxyguanosine (8-OH-dGuo) formation in lung tissues caused by NNK treatment. Mice were given 2% tea, 560 ppm EGCG, or 1120 ppm caffeine in drinking water for 13 weeks. The inhibition of 8-OH-dGuo formation in lung DNA by green tea and EGCG is consistent with their ability to inhibit lung tumorigenesis by NNK.

British Journal of Cancer, vol. 84, no. 6, pp. 844–850, 2001. ABSTRACT: Catechins are key components of teas that have anti-proliferative properties. This study investigated the effects of green tea catechins on intracellular signaling and VEGF induction in vitro in serum-deprived HT29 human colon cancer cells and in vivo on the growth of HT29 cells in nude mice. In the in vitro studies, (-)-epigallocatechin gallate (EGCG), the most abundant catechin in green tea extract, inhibited Erk-1 and Erk-2 activation in a dose-dependent manner. Treatment with EGCG inhibited tumour growth (58%), microvessel density (30%), and tumor cell proliferation (27%) and increased tumor cell apoptosis (1.9-fold) and endothelial cell apoptosis (3-fold) relative to the control condition (P < 0.05 for all comparisons). EGCG may exert at least part of its anticancer effect by inhibiting angiogenesis through blocking the induction of VEGF.

ABSTRACT: Previous studies have shown that some polyphenol compounds from green tea possess anticancer activities. In this study, they determined the cancer chemopreventive potentials of 10 representative polyphenols. Among the 10 polyphenols, EGCG showed the most potent antiproliferative effects, and significantly induced cell cycle arrest in the G1 phase and cell apoptosis.
- Mandel S et al. Multifunctional Activities of Green Tea Catechins in Neuroprotection. Neurosignals. 2005;14(1-2):46-60. DOI: 10.1159/000085385. ABSTRACT: Many lines of evidence suggest that oxidative stress resulting in reactive oxygen species (ROS) generation and inflammation play a pivotal role in the age-associated cognitive decline and neuronal loss in neurodegenerative diseases including Alzheimer's (AD), Parkinson's (PD) and Huntington's diseases. One cardinal chemical pathology observed in these disorders is the accumulation of iron at sites where the neurons die. The buildup of an iron gradient in conjunction with ROS (superoxide, hydroxyl radical and nitric oxide) are thought to constitute a major trigger in neuronal toxicity and demise in all these diseases. Thus, promising future treatment of neurodegenerative diseases and aging depends on availability of effective brain permeable, iron-chelatable/radical scavenger neuroprotective drugs that would prevent the progression of neurodegeneration. Tea flavonoids (catechins) have been reported to possess potent iron-chelating, radical-scavenging and anti-inflammatory activities and to protect neuronal death in a wide array of cellular and animal models of neurological diseases. Recent studies have indicated that in addition to the known antioxidant activity of catechins, other mechanisms such as modulation of signal transduction pathways, cell survival/death genes and mitochondrial function, contribute significantly to the induction of cell viability. This review will focus on the multifunctional properties of green tea and its major component (-)-epigallocatechin-3-gallate (EGCG) and their ability to induce neuroprotection and neurorescue in vitro and in vivo. In particular, their transitional metal (iron and copper) chelating property and inhibition of oxidative stress.
- Biasibetti R et al. Green tea (-)epigallocatechin-3-gallate reverses oxidative stress and reduces acetylcholinesterase activity in a streptozotocin-induced model of dementia. Behav Brain Res. 2013 Jan 1. DOI: 10.1016/j.bbr.2012.08.039. ABSTRACT: Alzheimer's disease (AD) is the most prevalent form of dementia. Intracerebroventricular (ICV) infusion of streptozotocin (STZ) provides a relevant animal model of chronic brain dysfunction that is characterized by long-term and progressive deficits in learning, memory, and cognitive behavior, along with a permanent and ongoing cerebral energy deficit. Numerous studies on green tea epigallocatechin gallate (EGCG) demonstrate its beneficial effects on cognition and memory. As such, this study evaluated, for the first time, the effects of sub-chronic EGCG treatment in rats that were submitted to ICV infusion of STZ (3mg/kg). Male Wistar rats were divided into sham, STZ, sham+EGCG and STZ+EGCG groups. EGCG was administered at a dose of 10mg/kg/day for 4 weeks per gavage. Learning and memory was evaluated using Morris' Water Maze. Oxidative stress markers and involvement of the nitric oxide (NO) system, acetylcholinesterase activity (AChE) and glucose uptake were evaluated as well as glial parameters including S100B content and secretion and GFAP content. Our results show that EGCG was not able to modify glucose uptake and glutathione content, although cognitive deficit, S100B content and secretion, AChE activity, glutathione peroxidase activity, NO metabolites, and reactive oxygen species content were completely reversed by EGCG administration, confirming the neuroprotective potential of this compound. These findings contribute to the understanding of diseases accompanied by cognitive deficits and the STZ-model of dementia.
- Rasoolijazi H et al. The Beneficial Effect of (-)-Epigallocatechin-3-Gallate in an Experimental Model of Alzheimer’s Disease in Rat: a Behavioral Analysis. Iranian Biomedical Journal. October 2007. ABSTRACT: rogressive cognitive decline is one of the hallmark symptoms of Alzheimer’s disease (AD) which can be modeled by β-amyloid injection into specific regions of brain. Since epigallocatechin-3-gallate (EGCG) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether EGCG administration protects against β-amyloid-induced memory and coordination impairment in rats. Methods: Animals (male Wistar rats) were divided into four groups: sham operated, EGCG-pretreated sham operated (sham + EGCG), untreated lesion (lesion), and EGCG-pretreated lesion (lesion + EGCG). Animals in lesion, lesion + EGCG, and sham + EGCG groups received sterile saline or saline plus EGCG (10 mg/kg) intraperitoneally one day pre-surgery and every other day for three weeks. The lesion was induced one day after EGCG pretreatment by injection of 4 μl of sterile saline or water containing 2 nmol/μl β-amyloid (1-40) into the hippocampal fissure. For behavioral analysis, psychomotor coordination (PMC) index and spontaneous alternation behavior were assessed using Rota-rod Treadmill and Y-maze, respectively at the third week post-lesion. Results: We found that β-amyloid (1-40) injection into hippocampus can decrease these behavioral indexes in lesion group in comparison with sham group which is similar to behavioral changes in AD. On the other hand, pretreatment with EGCG can improve the PMC index and spatial Y-maze alternation in the lesion + EGCG group in comparison with lesion group. Conclusion: We concluded that EGCG can be effective in restoring β-amyloid-induced behavioral derangements in rats regarding coordination and memory abilities.

J Agric Food Chem. 2010 Feb 24;58(4):2095-9. doi: 10.1021/jf9024807. ABSTRACT: Curcumin is the lipid-soluble antioxidant compound obtained from the rhizome of Curcuma longa Linn, also known as turmeric. Curcumin targets multiple chemotherapeutic and inflammatory pathways and has demonstrated safety and tolerability in humans, supporting its potential as a therapeutic agent; however, the clinical literature lacks conclusive evidence supporting its use as a therapeutic agent due to its low bioavailability in humans. The purpose of this study was to quantify plasma levels of free curcumin after dosing of a solid lipid curcumin particle (SLCP) formulation versus unformulated curcumin in healthy volunteers and to determine its tolerability and dose-plasma concentration relationship in late-stage osteosarcoma patients. Doses of 2, 3, and 4 g of SLCP were evaluated in 11 patients with osteosarcoma. Plasma curcumin levels were measured using a validated high-performance liquid chromatography method. The limit of detection of the assay was 1 ng/mL of curcumin. In healthy subjects, the mean peak concentration of curcumin achieved from dosing 650 mg of SLCP was 22.43 ng/mL, whereas plasma curcumin from dosing an equal quantity of unformulated 95% curcuminoids extract was not detected. In both healthy individuals and osteosarcoma patients, high interindividual variability in pharmacokinetics and nonlinear dose dependency was observed, suggesting potentially complex absorption kinetics. Overall, good tolerability was noted in both healthy and osteosarcoma groups.

- Aranow C. Vitamin D and the Immune System. J Investigative Medicine, 2011 Aug;59(6):881-886. ABSTRACT: Quote: "It is now clear that vitamin D has important roles in addition to its classic effects on calcium and bone homeostasis. As the vitamin D receptor is expressed on immune cells (B cells, T cells and antigen presenting cells) and these immunologic cells are all are capable of synthesizing the active vitamin D metabolite, vitamin D has the capability of acting in an autocrine manner in a local immunologic milieu. Vitamin D can modulate the innate and adaptive immune responses. Deficiency in vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection. As immune cells in autoimmune diseases are responsive to the ameliorative effects of vitamin D, the beneficial effects of supplementing vitamin D deficient individuals with autoimmune disease may extend beyond the effects on bone and calcium homeostasis."
- Autier P, Gandini S. Vitamin D Supplementation and Total Mortality: A Meta-analysis of Randomized Controlled Trials. Arch Intern Med. Sept. 10, 2007;167(16):1730-1737. ABSTRACT: This study identified 18 independent randomized controlled trials, including 57 311 participants. A total of 4777 deaths from any cause occurred during a trial size-adjusted mean of 5.7 years. Daily doses of vitamin D supplements varied from 300 to 2000 IU. The trial size-adjusted mean daily vitamin D dose was 528 IU. In 9 trials, there was a 1.4- to 5.2-fold difference in serum 25-hydroxyvitamin D between the intervention and control groups. Intake of ordinary doses of vitamin D supplements seems to be associated with decreases in total mortality rates.

The analysis adjusted for demographics and clinical factors (season, body mass index, smoking history, asthma, and chronic obstructive pulmonary disease). Serum 25(OH)D levels were inversely associated with recent upper respiratory tract infections.

ABSTRACT: This randomized, double-blind, placebo-controlled trial compared vitamin D(3) supplements (1200 IU/d) with placebo in schoolchildren. The results suggested that vitamin D(3) supplementation during the winter may reduce the incidence of influenza A, especially in specific subgroups of schoolchildren.

ABSTRACT: The results of this study suggest that the oral vitamin D supplement vehicle has an impact on its bioavailability, thus it is important to take into account how much of the supplied vitamin D will be absorbed. To maximize the full exploit of supplement, the best delivery strategy should be employed. In this study, the microencapsulated form of vitamin D was the most bioavailable.

Since iWell, I haven’t even had a cold!
As both a discerning consumer and a healthcare professional deeply involved in wellness, I've made Biotest's Vitamin D supplement a cornerstone of my health regimen. Trust is paramount when it comes to supplements, and this company has earned mine without a shadow of a doubt. With Vitamin D increasingly spotlighted in research for its role in bolstering immunity, this product's formulation shines as both top-quality and efficacious. I appreciate the additional enhancements they've included alongside the vitamin D, enhancing its benefits. Consequently, I wholeheartedly recommend this supplement to all my patients. Over the past two years, many have come to rely on it as a crucial component of their wellness strategy. Kudos to Biotest for consistently delivering products that not only meet but exceed quality expectations. Unlike many competitors, Biotest genuinely commits to the integrity and efficacy of their offerings. For that, I am truly grateful.


Keeps me going
Great product which keeps me running and lifting. Would not be where I am today without it.


Staying well and keeping well with iWell
My wife and I started on this product as soon as it came out. We were interested in staying in optimal health in light of the world health issues we have all been dealing with. We were also big Curcumin fans, so when this product combining both and other immune-boosting elements came out, we were stoked. It's been great, and many of my patients are taking it. I highly recommend it! Great product.


Seems good
This seems like a good product; however, I have to take it at night because it make you bloated AF. Also I am surprised that there is no Vitamin Ks, beta carotene, or liposomal Vitamin C.




Customer service
Excellent, more so because I received a part of my order damaged and BioTest responded immediately and remedied the issue satisfactorily.
