Did you drink coffee after your meal? If so, take your supplements now.

If you take vitamin or mineral supplements within two hours of drinking coffee, you may not experience their full effects. This is especially true for supplements containing vitamin D and iron.

 

The reason is the caffeine found in coffee, black tea, and green tea. Caffeine interferes with the absorption of vitamin D and iron in the stomach. Vitamin D absorption receptors are secreted in the small intestine, and caffeine functions to block this process. Because iron binds well to caffeine, if it encounters caffeine before being absorbed in the stomach, they stick together and are excreted in the urine. Caffeine reduces the absorption rate of iron by up to 80%.

 

Water-soluble vitamins, such as Vitamins B and C, also require caution. This is because they are affected by the diuretic effect of caffeine. Water-soluble vitamins are excreted in urine, leaving only the amount necessary for the body.

 

The diuretic effect of caffeine can increase the amount of water-soluble vitamins excreted in urine. Since minerals such as calcium are also nutrients excreted in urine, their consumption with caffeine should be avoided.

It takes about two hours for caffeine to be eliminated from the body. If you plan to take vitamin or mineral supplements, it is best to wait at least two hours after drinking coffee.

 

============

About 30 minutes to an hour after taking the medicine

I'm drinking coffee.

 

Conversely, if you drink coffee

I should remember that it's after 2 hours.

 

I thought it was almost 30 minutes.
