Drinking Lots of Green Tea Could Wreak Havoc on Your Fertility

December 16, 2015 2 min read

Green tea is loaded with a bunch of potential health benefits! It tastes delicious, is loaded with antioxidants, gives a nice energy boost and keeps your metabolism humming along. However, it could be negatively affecting something else. A study that is being published in the January 2016 issue of the Journal of Functional Food, has found that drinking too much green tea can have a negative impact on not only your fertility, but that of your fella's as well. For the purposes of the study, researchers exposed 48 Dropsophilia melanogaster fruit flies to various doses of the antioxidants, known as green tea polyphenols (GTP), that are found in your favourite warm beverage. They gave six flies of each sex four different amounts of GTP: zero, two and a half, five, and 10 milligrams. After, the flies were dissected and the water, lipid, and protein levels of the flies' reproductive organs were examined for toxicity.   [bctt tweet="Drinking Lots of Green Tea Could Wreak Havoc on Your Fertility"] They discovered that the female fruit flies given 10 milligrams of GTP had a "significant reduction in reproduction." The offspring of the flies given the highest doses were smaller as adults compared to the control group. These baby flies also had genital abnormalities. The males had testicle atrophy and the females had smaller ovarian structures and fewer mature eggs. Overall, the researchers said the effects of GTP were more noticeable in the female flies. So if you are looking to start a family, should you be worried? Well, it is important to take a moment and note that this study was done on a ridiculously small number of fruit flies and not on humans. However, the authors of the study say, "considering the highly conserved pathways between fruit fly and mammalian reproductive systems, the fruit fly is considered an excellent model system for the evaluation of drug toxicities." They are certainly used in a great deal of biomedical research. Basically, if you are pregnant or looking to become pregnant in the near future, it is always best to consult your ob-gyn on what foods are safe for you to consume. The good news is, if you are an occasional or moderate drinker of green tea, you are likely safe. Just like everything else, moderation appears to be the key. Are you a big green tea drinker? Are you a little concerned by these findings? Source: Women's Health

Shipping & Delivery

Due to COVID-19, shipping systems the world over are experiencing abnormal delays. There is an enormous demand on postal and delivery services as online shopping has skyrocketed, due to store closures and stay-at-home mandates. This is an unprecedented situation, and we are working around the clock to fulfill your orders as quickly as possible. To be clear, we are filling orders in 4-6 days, and we are shipping immediately after that. Once shipped, our shipping partner, UPS, will get your order out to you as quickly as possible. Thanks for your support and understanding.

Are you in Canada? Specifically, are you outside of a metropolitan centre? We need to alert you to a disruption in shipping due to COVID-19. Our preferred shipping provider, UPS, has informed us that they cannot guarantee express shipping for many locations. We have also seen that packages delivered to Toronto, Ottawa, Vancouver, etc, are not waylaid, but packages delivered to areas just outside of these cities are being held in transit for days or even weeks. UPS has discontinued their guarantee of 1-4 day delivery, which you can read more about here. Therefore, we can guarantee early fulfillment but not early delivery of our goods from our warehouse to your door at this time.


We want you to start your fitness journey with us as quickly as possible, that’s why we send every package to the USA & Canada via expedited or standard shipping with our partners at UPS. Once your order is received and processed, it typically takes 2-4 days to get to you once it leaves our warehouse. That’s our commitment and we stand by it.

We ship within Canada and the United States via UPS with Standard & Expedited shipping (whichever is faster)

For locations outside of the US and Canada, we ship using FedEx International (EUROPE and Other Nations), which is usually in transit for 7-10 business days, depending on location.

We ship all of our physical products with UPS, from our warehouse location in Kingston, Ontario, Canada. Delays caused due to custom withholds are not included in these estimated delivery times.

Returns & Exchanges

BodyRock Equipment

We offer a 30-day return policy, as long as: it is not more than 30 days past the date of delivery; and your item is in its original condition and packaging with the original order number. Refunds will be issued when the equipment is received back to the BodyRock warehouse, minus the original cost of shipping, and the customer is responsible for the costs of return shipping. To request a refund on physical product purchases, please contact us.

Digital Products

We cannot issue refunds on digital goods such as e-books or videos, as these are non-tangible goods that are irrevocable once the order is placed.
