Grapefruit juice increases estrogen?




A lot of people don’t realize how damaging excessive estrogen is. It’s damaging to both men and women.

In this study, they tested the effects of grapefruit juice on getting rid of estrogens in the body.

It’s long been known that grapefruit juice contains chemical compounds that slow down the body’s ability to get rid of estrogen.

The most potent form of estrogen is estradiol. And the scientists here used women that had no ovaries, so that they could give these women a single dose of oral estradiol and observe the effects of grapefruit juice without worrying about the ovaries’ effects of adding more estrogen.

Grapefruit juice had a stunning effect. It delayed the body’s ability to get rid of estrogen.

This is a great argument for not drinking grapefruit juice or eating grapefruits.

Estrogens effects include increasing cell division, increasing inflammation, increasing water retention. These are useful things in moderation.

But most men and women today have excessively high estrogen already. The last thing they need is grapefruit juice.

Could it be the quercetin?

Querecetin along with Naringenin and kaempferol are thought to be responsible chemicals in grapefruit juice. As the same researchers found: “At the highest concentrations tested of the respective flavonoid, there was approximately 75-85% inhibition of estriol formation.”

This may be a powerful argument to avoid supplementing with quercetin.

1. How are grapefruit and estrogen related?
Though grapefruit is considered a high source of Vitamins, it has a powerful effect on estrogen levels in the body. It is known that grapefruits have very important ingredients like Vitamin C, antioxidants and phytonutrients which are essential for the human body. Grapefruit consists of compounds that can greatly reduce the risk of cholesterol and can effectively lower blood pressure levels. It also consists of many other nutrients like Calcium, Vitamin E, niacin, folate, potassium, phosphorus, manganese, and zinc. Grapefruit does also have many heart benefits and has also been found extremely beneficial in promoting a healthy triglyceride to HDL ratio in the blood. Some research papers show that Grapefruit consumption can lead to an increase in the Estrogen levels in the body thus leading to Breast Cancer in women. However, the effect of grapefruit consumption on Men may not be as complex. Though grapefruit has been connected to the increase in the estrogen levels in the body, for men whose testosterone and estrogen levels are normal, it might have no harmful effects.
Grapefruit itself is not high in estrogens but it contains certain compounds which block the natural breakdown of the estrogens in the body. This usually leads to the increase of the estrogen levels in the body. Men’s body does contain some level of estrogens which is naturally occurring, in addition to testosterone. Likewise, the female bodies also contain some levels of Testosterone.
Grapefruit consumption can be harmful only for those who already have a higher than normal estrogen level in their body. In such a case it can cause physical symptoms like “Man boobs” Also grapefruit consumptions can boost the production of aromatase, often considered the enzyme which converts testosterone to estrogen. The best way to prevent any adverse health conditions is to have grapefruits in moderation. 

2. Does grapefruit increase estrogen? 
Estrogen though commonly referred as a female hormone, is found naturally in the male body and is very beneficial for a robust health. Estrogen is important to keeping the bones strong and supple, it boosts the elasticity of the skin, and also protects against diseases like arteriosclerosis. Though Grapefruit itself may not contain compounds which boost or increases Estrogen, it certainly contains compounds that can hinder the natural breakdown of estrogen in the body. This leads to the increase in the existing estrogen levels in the body.
The consumption of grapefruit actually affects aromatase which is an enzyme found both in male and female bodies. The function of Aromatase is to produce female sex hormones or estrogens and in a male body, this happens by the natural conversion of testosterone to estrogen. Grapefruit consumption may not affect those who have a fairly balanced level of estrogen that is natural, but for those who may have an estrogen imbalance, it can cause specific physical disorders. One such example is the growth of the mammary glands among men or “Man boobs”. The high levels of estrogens can also cause other health problems like sudden and severe vomiting, vision problems, pain in the chest, memory problems, lumps or changes in the breast and in major cases can cause nipple secretions.

3. Does grapefruit juice increase testosterone?
The nutritional benefits of the grapefruit have made it an interesting find for many health-conscious American folks. But beyond its health benefits, grapefruit juices might not be the right food for those who are interested in improving their male hormone levels.
Grapefruit has been found to be rich in antioxidants and is Vitamin C which is adequate for the body's immune and health system. According to the Journal of Agricultural and Food chemistry, drinking grapefruit juice has been found to lower the triglyceride levels. In addition, it helps to balance the cholesterol levels in the body.
So does Grapefruit juice increase testosterone?
The research results are interesting. According to some research experts, Grapefruit juice has been found to increase the effectiveness when taken with supplements like prohormones. These prohormones are usually found to increase the level of testosterone, estrogen, and progesterone in the body. Consuming grapefruit juices with prohormone supplements can increase sex drive and aggression, which are normally testosterone enhancing indicators. But it can also cause side effects. Perhaps this is because Grapefruit juices along with supplementation or if taken with medications can provide a mixed bag of results.
Consuming grapefruit juice along with prohormones can also lead to an increase in weight gain. This is because of the increase in the levels of estrogen as well. This may lead to high blood pressure levels and in many cases has been found to cause liver damage as well.
But Avoid Grapefruit, if you are looking to boost your testosterone levels naturally!
This is because Grapefruit acts as a sort of catalyst for the body’s aromatase enzyme which happens to convert testosterone into estrogen. This can be counterproductive.
The best way to increase your testosterone levels is by increasing your intake of foods that are rich in zinc, Vitamin D and naturally occurring foods that improve testosterone levels naturally. High protein-rich foods have been found to play a vital role in the improvement of testosterone levels and thus can be a staple food diet when focussed on improving testosterone levels.
Some herbs like Ginger has been proven by medical research to improve fertility and increase testosterone levels. Zinc-rich foods like oysters, red meat, poultry, beans, nuts and shellfish are great sources of zinc which can help increase testosterone levels.
Did you know that pomegranates are known as aphrodisiacs because of its natural ability to improve libido and increase testosterone levels?
Vitamin D that is availed naturally, especially through good natural sunlight is a great way to improve the testosterone levels in the body. Unknown to many, dark green leafed vegetables are rich in magnesium which has been seen to boost testosterone levels naturally.
It is prudent to lose weight and stick to a daily regimen of exercise since that has been found to help boost testosterone levels naturally. Try to reduce stress and follow alternative practices like yoga and meditation. Those who exercise regularly do have high testosterone levels. Vitamin supplements are a great approach too.
But grapefruits juice as an alternative for improving testosterone levels is a topic that still needs a lot of research. Taken with supplements, Grapefruit juice can increase the effectiveness of the supplements but by itself, it is a big no-no when it comes to boosting testosterone levels naturally.
