Try to avoid taking your vitamins with coffee or tea Caffeine also increases urination, which can decrease the concentration of water-soluble vitamins (B-complex and C). So, wait an hour after your morning brew to take supplements.
Furthermore, caffeine interferes with the metabolism of certain B vitamins, including thiamine. However, because caffeine increases stomach acid secretion, it actually boosts the absorption of vitamin B12.
Taking vitamin B-12 with vitamin C might reduce the available amount of vitamin B-12 in your body. To avoid this interaction, take vitamin C two or more hours after taking a vitamin B-12 supplement.
Caffeine has a mild diuretic effect, which leads to an increase in urination. As a result, water-soluble vitamins, such as B-vitamins and vitamin C can be depleted due to fluid loss. Research also demonstrated that the higher the level of caffeine, the more it interfered with vitamin D absorption.
It's usually best to take the tablets on an empty stomach. This means at least 2 hours after a meal or snack and at least 30 minutes before you eat again.
Vitamin C and vitamin B12 are water-soluble vitamins, which means you need water to absorb them. “Take water-soluble vitamins on an empty stomach with a glass of water,” recommends Dr. Perez-Gallardo.
Some beverages, including coffee, contain substances that could interfere with the absorption of some of the nutrients in your vitamin. It's better to drink your coffee about 15 minutes before or a few hours after you take your vitamin.
Caffeine can interfere with the absorption of certain minerals, including magnesium, calcium, and iron, but the loss is minimal.
Foods that you should not eat at the same time as you take your iron include: High fiber foods, such as whole grains, raw vegetables, and bran. Foods or drinks with caffeine.
Due to its special role, vitamin B12 aids in the prevention of anemia, which mostly leads to fatigue. Even though the research available about the relationship between vitamin B12 and insomnia remains unclear, some studies² show that elevated levels of vitamin B12 do cause sleeplessness.
Some research indicates that higher amounts of vitamin B12 link to shorter sleep duration and a higher risk of insomnia. A 2007 study suggests it may also affect the 24-hour biological processes that help a person go from wakefulness through drowsiness to sleep.
Vitamin B12, for example, should definitely be taken in the morning. This is because it is important for energy metabolism, which may interrupt your sleep if taken at night.
Coffee also seems to impact on the metabolism of some B vitamins like thiamine. Vitamin B12, though, looks like being a possible exception – indeed, caffeine's stimulation of stomach acid production may actually assist, instead of compromise, your body's B12 absorption.
Vitamin B12 (also called methylcobalamin) isn't a stimulant like caffeine. However, maintaining optimum B12 levels plays a key role in preventing you from feeling tired and weak.
How do coffee and alcohol affect Magnesium? Because coffee is a diuretic, it causes your body to flush out magnesium quickly, meaning that your body doesn't have enough time to properly break down the mineral and make the most of it.
Heat is known to destroy nutrients, so the hot water in your tea and coffee should be a no-go when it comes to taking your vitamin tablets. Tannins and caffeine can interfere with the absorption of some vitamins and minerals especially, Iron and Vitamin D as it is thought to reduce the expression of receptors.
Answer : In general, theres no need to be concerned about tea blocking the absorption of vitamins or other nutrients, according to Jeffrey B. Blumberg, PhD, director of the Antioxidants Research Laboratory at Tufts Jean Mayer USDA Human Nutrition Research Center on Aging, who has studied tea at length.

So, wait an hour after your morning brew to take supplements. Caffeine-free herbal tea, on the other hand, contains fewer tannins than regular tea.
However, once again, coffee's tannins may interfere with this process by binding to the medications and limiting how much the body can absorb. Health experts advise avoiding coffee within 1-2 hours of taking tricyclic antidepressants in order to ensure their efficacy.
Water pills (Diuretic drugs) interacts with CAFFEINE
Caffeine can decrease potassium levels. "Water pills" can also decrease potassium levels. Taking caffeine along with "water pills" might make potassium levels drop too low.
Take this medication by mouth with or without food as directed by your doctor or the product package, usually once daily. Use this product regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Normally, vitamin B12 is readily absorbed in the last part of the small intestine (ileum), which leads to the large intestine. However, to be absorbed, the vitamin must combine with intrinsic factor, a protein produced in the stomach.
In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form. From there, vitamin B12 combines with a protein called intrinsic factor so that it can be absorbed further down in the small intestine. Supplements and fortified foods contain B12 in its free form, so they may be more easily absorbed.
