While a number of B complex supplements are available at grocery stores, supplement stores, and online, not all of them contain the most absorbable forms of these nutrients.
Plus, most B complex vitamins contain folic acid, the synthetic form of the folate found in food. Folic acid differs structurally from folate and has different effects in the body.
Research has shown that high intake of folic acid can cause unmetabolized folic acid to accumulate in the blood, which has been associated with negative health outcomes, such as an increased risk of autism in offspring and accelerated mental decline (
For this reason, many experts suggest supplements containing 5-MTHF.
Plus, 5-MTHF is more appropriate for those who have genetic polymorphisms, such as methylenetetrahydrofolate reductase (MTHFR), that affect enzymes involved in folate metabolism (
When searching for a B complex vitamin, it's important to purchase products from trusted brands, such as the ones listed above. This can help ensure you're taking a high quality supplement that contains the readily absorbable forms of nutrients.
B vitamins are water soluble, and your body excretes whatever it doesn't need via urine. However, B vitamin toxicity can still occur.
This is why many people experience bright yellow urine after taking high dose B vitamins. While it may be surprising, it's a harmless side effect (
However, an excessively high intake of certain B vitamins, such as niacin (B3) and pyridoxine (B6), can lead to complications like nerve damage, vomiting, and even liver damage (
Even though these side effects are rare, it's important to follow the directions on the supplement bottle or the dosing instructions your doctor provides.
This is especially true when taking a multivitamin that contains fat-soluble vitamins, as these are not excreted by your body like water-soluble vitamins.
Many people, including older adults, those with anxiety or depression, and people taking common medications, such as birth control and antidiabetic medications, may benefit from a B complex supplement (
Your doctor can help you determine whether taking a B complex vitamin is the right choice for you and suggest the optimal dosage.
