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.
Caffeine will increase the excretion of your B12 and other B vitamins.
Your intestines absorb vitamin B12 from food. A protein your stomach makes called “intrinsic factor” helps your body absorb it.
Vitamin B12 is a key nutrient that your body needs for many essential functions. It's found in large amounts in animal products, fortified foods, and dietary supplements. Some of the richest sources are liver, beef, sardines, clams, and dairy products.

Vitamin B12 is a water-soluble vitamin. Water-soluble vitamins dissolve in water. After the body uses these vitamins, leftover amounts leave the body through the urine. The body can store vitamin B12 for years in the liver.
Reasons for Insufficient Vitamin B-12 Absorption
People who can't absorb vitamin B-12 have either low levels of stomach acid, which your body needs to separate bound vitamin B-12 that occurs naturally in foods, or cannot produce a protein called intrinsic factor.
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.
Long-term vitamin B12 deficiency can cause nerve damage. This may be permanent if you do not start treatment within 6 months of when your symptoms begin.

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.
As summarized in the table provided, vitamin B12 (cobalamin) absorption and utilization by the body can be compromised with the chronic use of certain medications which include: colchicine, chloramphenicol, ethanol, histamine 2 receptor antagonists (H2RA), metformin, and proton pump inhibitors (PPI).
