Dosage Recommendations. When Should I Take EGCG?
Although EGCG is a natural compound found in green tea and other foods, there is no specific time of the day recommended for taking it.
But to avoid digestive disturbances, some people prefer to consume their supplements either in the morning or with a meal.
Despite being diligently studied for many years, the effects of EGCG vary greatly.
It is thought that this could be due to its susceptibility to oxygen breakdown as well as absorption difficulties within the digestive system.
Though the exact cause of this phenomenon is yet to be fully understood, it may originate from EGCG’s swift transition through the small intestine, thereby leading to degradation by bacteria in the large intestine.
This has left us at a loss in regard to what exact dosages we should be recommending.
An 8-ounce cup of brewed green tea is estimated to contain 50–100 milligrams of EGCG, though dosages commonly used in the analysis are often much higher. The quantity has not been precisely regulated, however.
According to analysis, a daily intake of 800 mg or more of epigallocatechin 3-gallate can elevate the levels of transaminases in your bloodstream, which is an indicator of potential liver damage.
To reduce this risk and ensure safety when taking solid supplemental forms of epigallocatechin 3-gallate, it has been suggested that individuals should limit their intakes to no more than 338mg per day.
How Much EGCG is Safe Daily?
In light of current research, an Observed Safe Level of 704 mg EGCG/day for adults consuming GTEs in beverage form can be considered. As for a bolus dose, the recommended safe intake level is 338 mg EGCG/day.
EGCG Side Effects and Risks
It is imperative to recognize that supplements may bring serious side effects, and they are not guaranteed to be 100% safe, such as:
- liver and kidney failure
- dizziness
- low blood sugar
- anemia
While some professionals speculate that these damaging results may be due to the toxins present in supplements rather than epigallocatechin 3-gallate itself, one should always use caution when deciding to take this particular supplement.
If you are expecting, supplemental doses of EGCG should be avoided as it could affect the body’s metabolism of folate–a B vitamin that is crucial for your baby’s growth and development.
Without proper levels of folate, there may be an increased risk of birth defects such as spina bifida.
To ensure the safety of breastfeeding women and their babies, it is best to avoid taking supplements until further research can be conducted.
Additionally, caution should be taken as there have been reports that epigallocatechin 3-gallate could interfere with the absorption of certain medications like cholesterol-lowering drugs and antipsychotics.
To promote your safety and well-being, always speak to a healthcare professional prior to beginning any new dietary supplement.
