Short answer: yes, but the effect is probably not enough to concern most people.
There is some evidence that tea can inhibit the absorption of iron, by certain chemicals in the tea binding to iron in other foods. This binding only happens for non-heme iron, such as iron from plant and dairy sources. Iron in red meat, poultry, and fish is unaffected by tea consumption.
The studies that have examined tea consumption on a large scale found that this effect is not large enough to be a matter of concern. It is mitigated by consuming foods rich in Vitamin C with a meal, as Vitamin C improves iron absorption. Concerned people can drink tea between, rather than with meals, to minimize this effect as well.

Does vitamin c impair iron absorption?
NO
Is a block of iron element compound or a mixture?
Yes. Pure iron is an element.
What iron salts have higher GI absorption?
Ferrous sulfate (FeSO4)
How do you test iron ions?
There are lots of ways. Atomic absorption spectroscopy comes to mind.
Which nutrients enhances iron absorption from the intestinal tract?
Vitamin C
Substance in coffee and tea that reduces iron absorption?
phytates
Does caffeine affect iron absorption?
No, caffeine directly affect the absorption of iron. It is the polyphenol compounds in coffee and tea that negatively affect iron absorption. Drinks containing polyphenol compounds should be avoided at least an hour prior to, and and hour after taking iron supplements or eating foods that contain iron to ensure they do not interfere with iron absorption.
What factors reduce iron absorption?
The foods which decrease iron absorption are some soy-based foods, calcium foods, beverages containing caffeine and tannin (do not take within 2 hours of taking iron). Do not use allspice and bayberry spices.
Does green tea raise hemoglobin?
Yes, it lowers non-heme iron, which is iron found in vegetables. Heme iron, iron found in meat, it generally unaffected by the tannis found in tea. If you eat meat or are not anemic, then you can drink all the tea you want. You can mitigate this effect by eating foods rich in Vitamin C, like fresh fruits and vegetables, with your meal, as they boost absorption of non-heme iron. You can also drink tea between, rather than with meals.
How do you improve the absorption of iron from supplements when taking them with something.?
tea. b. meat. c. milk. d. whole-grain bread
Is a whole glass of lemon good for you?
Yes. Green tea is known to be healthy, and lemon adds vitamin C. There are additional benefits of the combination: tea can inhibit iron absorption, but vitamin C improves iron absorption, counteracting this effect. The vitamin C in the lemon may also improve absorption of some of the antioxidants in the tea. It can also be healthy to drink green tea blended with various lemon-scented herbs, such as lemongrass, lemon balm, lemon verbena, or lemon myrtle, as these herbs also have many positive effects on health.
What foods to eat when you have high iron?
Some compounds are found naturally in foods that will limit iron absorption. The following foods, when eaten in large quantity, may prevent iron from being absorbed from the foods you eat.When you eat foods that contain more vitamin C - like those below, you will increase the body's absorption of iron from foods.Whole grain cereals and breads - the phytates and fibers may block absorptionMilk and dairy products - the calcium and phosphorus may block absorptionTeas and coffee - Tannic acid found in tea / coffee may prevent iron absorption
Is it a low water content of a body absorbs iron completely?
you need water to get things runing orange juice (as a source of vitamin C) increase iron absorption by 85 percent. green tea instead of water, iron absorption reduced by 62 percent Coffee reduce iron absorption by 35 percent. The iron in meat is about 40 percent heme and 60 percent non-heme. non-heme form found in plant sources such as grain products, fruits, vegetables, and in iron fortified foods.
How far apart should you take calcium with vitamin d and iron?
Take the Calcium and Vit D at least 3-4 hours apart from your iron supplement. Take your iron with vitamin C for best absorption and avoid black tea with your iron too. :-)
How do you get iron supplement?
Spinach is a source of iron as is liver or apricots. Don't drink tea with a meal as it prevents the absorption of iron. Citrus juice such as OJ with your meal is a way to enhance iron absorption from food.
How do you make a golum in minecraft?

What is a feature of iron absorption?
Your body automatically increases iron absorption when you have an increased physiological need for iron, for example, in children during rapid growth periods and during pregnancy and lactation. Iron absorption is decreased in people with low stomach acid (hypochlorhydria), a condition that is common in the elderly and those who use antacids frequently. In addition, iron absorption can be decreased by caffeine and by tannins found in coffee and tea. People with healthy iron status need not worry about the impact of tea tannins on their iron absorption. People who are iron deficient, however, should wait at least one hour after a meal before drinking green or black tea. Phosphates found in carbonated soft drinks can also decrease iron absorption. The best way to increase your absorption of iron is to ensure that you consume sufficient vitamin C. A meal that contains about 25 milligrams of vitamin C may as much as double your absorption of iron from that meal. Your body uses copper to help transport iron around your body, and iron-deficiency anemia may sometimes reflect the more basic underlying problem of copper deficiency. Vitamin A may also help improve iron status, and perhaps because of their relationship to stomach acidity levels, so might amino acids and organic acids (like citric acid or malic acid). You may have trouble absorbing iron in the presence of too much calcium (300 milligrams or more). People with high iron requirements might want to avoid taking calcium supplements with meals. Other nutrients that can lower absorption of plant iron include polyphenols (like tannins) and soy proteins. Phytates, found in whole grains, legumes and other seeds, may also decrease iron absorption by forming compounds with the mineral that cannot be absorbed through your digestive tract. Soaking seeds overnight can reduce the phytates in food and increase the absorption of iron. Oxalates, found in spinach and chocolate, may also decrease iron absorption. However, you are still able to absorb helpful amounts of iron from plant foods that contain any or several of these nutrients, and foods like spinach, whole wheat, whole grain rice, soybeans, and other legumes are still very much worth eating, even when iron absorption from these foods is less than 100%. Much of the iron in whole grains is found in the bran and germ. As a result, the milling of grain, which removes the bran and germ, eliminates about 75% of the naturally occurring iron in whole grains. Refined grains are often fortified with iron, but the added iron is less absorbable than the iron that naturally occurs in the grain. Cooking with iron cookware will also add iron to food.
