Other Vitamins and Minerals Caffeine may reduce the absorption of manganese, zinc and copper. It also increases the excretion of the minerals magnesium, potassium, sodium and phosphate. There is also evidence that caffeine interferes with the action of vitamin A.

Does caffeine inhibit vitamin absorption?
Any beverage or food containing caffeine such as coffee, tea, chocolate and some sodas can inhibit the absorption of vitamins and minerals and increase their excretion from the body.
What does caffeine stop the absorption of?
Caffeinated drinks like coffee and tea have been shown to inhibit iron absorption. However, this is more likely due to their polyphenol contents, not caffeine itself. Caffeinated foods and drinks are not associated with iron deficiency in healthy people, as iron absorption is affected by many other dietary factors.
Does caffeine affect vitamin B12 absorption?
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.
Is it bad to take vitamins with coffee?
Try to avoid taking your vitamins with coffee or tea The tannins and caffeine can interfere with the absorption of many vitamins and minerals, especially iron. Caffeine also increases urination, which can decrease the concentration of water-soluble vitamins (B-complex and C).
Does caffeine affect Omega 3 absorption?
The caffeine in coffee or tea can speed up the digestive process, increasing the contractions that force food through your digestive tract. When omega-3 is moved more quickly through the digestive system, there will be less time for you to absorb all those lovely essential fatty acids.
Does caffeine deplete zinc?
Zinc Concerns Phytates, an antioxidant in coffee, may inhibit absorption of zinc. Coffee has been found to affect the bio-availability of zinc, in lab tests, by up to 21 percent or 32 percent. The recommended daily intakes of zinc for men is 11 milligrams each day and 8 milligrams for women.
Does caffeine deplete vitamin B1?
Coffee can deplete us of nutrients. Heavy coffee consumption can cause a deficiency in B vitamins, and specifically B1, thiamine. This can make us feel fatigued, nervous and achy, and not provide any headache relief.
Does caffeine affect vitamin C?
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.
Does caffeine destroy collagen?
“It’s worth remembering that coffee doesn’t destroy collagen, it inhibits its production,” says nutritional therapist at the Pulse Light Clinic, Lisa Borg.
Does caffeine prevent calcium absorption?
Caffeine may very modestly reduce calcium absorption (by about 4 mg of calcium per cup of coffee), but this can be offset completely by adding 1–2 tablespoons of milk to your coffee.
Is it OK to take vitamin B12 with coffee?
No interactions were found between caffeine and Vitamin B12.
Does coffee affect vitamin C absorption?
However, did you know that caffeine interferes with the absorption of vitamin C, meaning that you might not be getting the full benefits of your healthy diet if you regularly drink coffee, tea or other caffeinated beverages alongside meals?
Can I take zinc with coffee?
Dr. Christian Goldsmith from Auburn University, Alabama, USA, have discovered that zinc can protect against the superoxide responsible for oxidative stress when taken together with a component found in foodstuffs such as wine, coffee, tea and chocolate.
How long after vitamins Can I drink caffeine?
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.
Does caffeine deplete magnesium?
Common substances — such as sugar and caffeine — deplete the body’s magnesium levels.
Does green tea block vitamin absorption?
Drinking green tea does interfere with nutrient absorption. Anti-oxidants such as polyphenols in green tea can bind iron, inhibiting its intestinal absorption. You may also have trouble absorbing vitamin B12.
Does caffeine affect folic acid absorption?
Caffeine is responsible for the homocysteine-increasing effects of coffee. These data suggest that a high caffeine intake would affect the bioavailability of folic acid and reduce serum folic acid levels.
Can I drink tea after taking vitamin D?
Vitamin D supplements should be taken along with the major meal of the day then whether it’s breakfast, lunch, or dinner. Taking it with a fruit, tea, coffee, or in-between meals won’t let the absorption happen,” she says.
Does caffeine deplete electrolytes?
It’s really quite simple… Caffeine does not cause dehydration, nor does it deplete the human body of electrolytes. That is, if you don’t over-consume caffeinated drinks.
Does oatmeal block nutrient absorption?
1) Soak your oats Grains contain phytic acid, which, when untreated, combines with calcium, magnesium, copper, iron and zinc within the intestinal track. This results in the blocking of the absorption of these minerals.
Does caffeine deplete potassium?
Taking an excess amount of caffeine (e.g. overdrinking caffeinated beverages) sometimes causes hypokalaemia. Although the detailed mechanism has not been clarified yet, an increased loss of potassium via the urine stream caused by the diuretic action of caffeine is proposed as one of the possibilities.
Does coffee cause vitamin B deficiency?
Conclusions: Coffee consumption was associated with reduced circulating B-vitamin concentrations. The observed effect profiles indicated that coffee consumption preferentially affected the upper, but not the lower, part of the B-vitamin concentration distributions.
Does tea affect vitamin absorption?
Unfortunately, tannins can also bind easily with some minerals such as iron, zinc and to a lesser extent calcium, and this can interfere with their absorption. It’s best to leave a 30-minute gap between eating a meal and drinking tea to make sure you have the best chance to absorb these minerals.
Does coffee inhibit protein absorption?
Does Coffee Reduce Protein Absorption? Again, no. While there are not many studies and research into the subject matter, coffee (or caffeine, to be precise) does not seem to negatively affect the body’s ability to absorb protein.
