Are You Taking Vitamin B12 and D at the Right Time? Key Tips for Better Absorption

Water-soluble and fat-soluble vitamins should not be taken together.

Are you ensuring that you take Vitamin B12 and Vitamin D at the optimal times? Here are some tips to maximize the benefits of your vitamin supplements.

Vitamin B12 is a vital nutrient present in various foods, including meat, fish, and dairy products. It can also be synthesized in a laboratory setting and is frequently combined with other B vitamins in supplements. 

This vitamin plays a crucial role in the proper functioning and development of numerous body components, such as the brain, nervous system, and blood cells. The active form of vitamin B12 is known as methylcobalamin, while cyanocobalamin, the most prevalent form found in supplements, requires conversion by the body to become active.

Vitamin D is a fat-soluble vitamin that belongs to a group of compounds, which includes vitamins D1, D2, and D3.

Your body synthesizes vitamin D naturally when exposed to sunlight. Additionally, you can obtain vitamin D from specific foods and supplements to maintain sufficient levels in your bloodstream.

This vitamin plays several crucial roles, with the most significant being the regulation of calcium and phosphorus absorption and supporting various bodily functions. 

There are two categories of vitamins: water-soluble and fat-soluble, each requiring different methods for absorption.

Water-soluble vitamins, such as Vitamin B12, are not stored in the body and are quickly excreted. Therefore, it’s essential to consume plenty of water to facilitate their absorption. The optimal time to take these vitamins is on an empty stomach in the morning. If that’s not possible, the next best option is to take them one hour after breakfast, allowing sufficient time for the food to settle, which enhances the absorption of the vitamins along with the water you consume.

The suggested daily intake of vitamin B12 is 2.4 micrograms. If you are unable to meet this requirement due to health issues or dietary gaps, a supplement may be necessary. A typical supplement can contain as much as 1500 micrograms (mcg), which is considered high potency; however, the body can only absorb a small fraction, up to 4 percent, since it is water-soluble. Therefore, the timing of taking the supplement is crucial and should be done on an empty stomach to enhance absorption.

Fat-soluble vitamins require consumption alongside fatty foods to enhance their bioavailability and absorption. These vitamins include A, D, E, and K. If you’re using vitamin D in powder form, it’s advisable to take it with milk, as the fat in milk aids in absorption. While vitamin D powder is more economical than capsules, it may not be effective for individuals with gastrointestinal problems.

It is crucial to remember that you should not exceed 4,000 IU of vitamin D without consulting a doctor.

Water-soluble and fat-soluble vitamins should not be taken together. This is one of the reasons why multivitamin capsules can create issues. The optimal time to take them is shortly after meals, accompanied by water.

Numerous studies indicate that it is advisable to avoid taking vitamin C and B12 simultaneously, as vitamin C may hinder the absorption of B12. However, since both vitamins are water-soluble, it is acceptable to consume them together when your stomach is slightly empty.
