Greenselect Phytosome

Also known as: Greenselect Phytosome, GSP, Green tea extract, Phytosome formulation, Caffeine-free green tea catechin extract

Overview

Greenselect Phytosome (GSP) is a proprietary, caffeine-free green tea extract formulated with lecithin to enhance the bioavailability of its key component, epigallocatechin-3-O-gallate (EGCG), and other catechins. Derived from green tea leaves, GSP is primarily used as a dietary supplement for its potential antioxidant, weight management, and cardiovascular health benefits. It is standardized to contain between 19% and 25% catechins, with at least 13% being EGCG. Research on GSP is considered moderate, with several clinical trials exploring its effects, though systematic reviews are limited. The quality of available evidence varies, with some well-designed studies alongside those with smaller sample sizes or methodological constraints. GSP is available in various oral forms, such as capsules and tablets, and is often marketed for its enhanced absorption compared to standard green tea extracts.

Benefits

Greenselect Phytosome has demonstrated potential benefits in several areas. A study involving individuals with borderline metabolic syndrome showed improvements in weight and waist circumference compared to lifestyle changes alone, suggesting a role in weight management. This study also indicated antioxidant and anti-inflammatory effects, with improvements in lipid profiles. Furthermore, preliminary research suggests potential anti-proliferative effects in breast cancer tissue, although these findings require further validation. Specifically, one study showed that 68% of subjects with metabolic syndrome no longer met the criteria after GSP treatment. While these results are promising, the evidence base is still developing, and more rigorous, large-scale studies are needed to confirm these benefits and establish the optimal conditions for their realization.

How it works

Greenselect Phytosome's mechanism of action primarily revolves around the antioxidant, anti-inflammatory, and potential anti-proliferative properties of its key component, EGCG. EGCG modulates various cell signaling pathways involved in lipid metabolism, insulin sensitivity, and potentially hormone regulation. The lecithin formulation enhances the systemic availability of EGCG, facilitating its interaction with these biological pathways. Specifically, EGCG targets signaling pathways involved in cell proliferation and survival, contributing to its potential anti-cancer effects. By influencing these pathways, GSP can impact overall metabolic health and reduce oxidative stress, contributing to its observed benefits.

Side effects

Greenselect Phytosome is generally considered safe, with limited reports of significant side effects. Common side effects are not well-documented in the literature, but some individuals may experience mild gastrointestinal upset. Rare side effects are also not well-documented. Due to its antioxidant properties, GSP may potentially interact with blood thinners, necessitating caution for individuals on such medications. While there are no well-established contraindications, caution is advised for individuals with bleeding disorders. Pregnant or breastfeeding women should consult their healthcare providers before using GSP. It is important to note that while GSP is generally safe, individual responses can vary, and it is always prudent to consult with a healthcare professional before starting any new supplement, especially if you have pre-existing health conditions or are taking other medications.

Dosage

The minimum effective dose of Greenselect Phytosome is typically around 300 mg per day, standardized to contain approximately 44.9 mg of EGCG. Optimal dosage ranges are not yet well-established, and more research is needed to determine the most effective and safe dosages for various health conditions. The maximum safe dose is also not clearly defined, so caution is advised when exceeding recommended doses. There are no specific timing recommendations, but consistent daily intake is generally suggested. The lecithin formulation is recommended to enhance bioavailability. No specific cofactors are required for GSP to be effective. As with any supplement, it is advisable to start with a lower dose and gradually increase it while monitoring for any adverse effects.

FAQs

Is Greenselect Phytosome safe to take with other medications?

GSP is generally safe, but it may interact with blood thinners. Consult a healthcare provider if you are taking any medications to avoid potential interactions.

When is the best time to take Greenselect Phytosome?

There is no specific timing recommendation, but consistent daily intake is advised. You can take it with or without food, depending on your tolerance.

What are the expected benefits of taking Greenselect Phytosome?

Potential benefits include weight management and antioxidant effects. Some studies suggest improvements in metabolic syndrome factors and potential anti-proliferative effects.

Can Greenselect Phytosome replace medical treatment?

No, GSP is not a substitute for medical treatment. Consult a healthcare provider for specific health conditions and follow their recommendations.

Are there any side effects associated with Greenselect Phytosome?

GSP is generally well-tolerated, but some individuals may experience mild gastrointestinal upset. Discontinue use and consult a healthcare provider if you experience any adverse effects.

Research Sources

  • https://aacrjournals.org/cancerpreventionresearch/article/10/6/363/46623/A-Presurgical-Study-of-Lecithin-Formulation-of – This pilot clinical trial investigated the effects of Greenselect Phytosome (GSP) in 12 early breast cancer patients over 4 weeks. The study found that GSP increased EGCG bioavailability and demonstrated anti-proliferative effects in breast cancer tissue, suggesting potential benefits in breast cancer management, although the small sample size limits the generalizability of the findings.
  • https://pubmed.ncbi.nlm.nih.gov/24348726/ – This controlled registry study examined the impact of GSP on 50 asymptomatic subjects with borderline metabolic syndrome over 24 weeks. The study revealed that GSP improved metabolic syndrome factors, particularly weight and lipid profiles, indicating its potential in managing metabolic syndrome. However, the lack of a randomized controlled design introduces limitations to the study's conclusions.
  • https://www.mdpi.com/2072-6643/14/24/5209 – This research explores the broader applications of green tea extracts and their impact on various health conditions. It provides a comprehensive overview of the potential benefits of green tea catechins, including EGCG, in promoting overall health and well-being. While it doesn't focus specifically on Greenselect Phytosome, it offers valuable context regarding the efficacy and safety of green tea extracts in general.
  • https://pubmed.ncbi.nlm.nih.gov/19594224/ – This study investigates the bioavailability of green tea catechins, including EGCG, when formulated with lecithin. The findings suggest that lecithin enhances the absorption and systemic availability of EGCG, which is a key factor in the efficacy of Greenselect Phytosome. This improved bioavailability may contribute to the observed health benefits of GSP compared to non-formulated green tea extracts.
  • https://onlinelibrary.wiley.com/doi/abs/10.1002/ptr.6697 – This article likely discusses the potential therapeutic applications of green tea extracts, including their antioxidant and anti-inflammatory properties. While the abstract provides limited details, it suggests that green tea extracts may have a role in preventing and managing various health conditions. Further investigation of the full article is needed to fully understand its relevance to Greenselect Phytosome.
