Why Do Multivitamins Matter on a Carnivore Diet?

Generally, it’s not necessary to have a multivitamin on the Carnivore Diet since animal foods provide the most necessary nutrients. Still, certain groups like professional athletes or older adults may need to have multivitamins and supplements on this diet for the following reasons:

Filling Nutritional Gaps for Certain Individuals

Sensitive individuals like pregnant women need more folate and iron to support fetal development and prevent anemia, and older adults need more vitamin D and calcium for bone health.

These extra vitamins may not be sourced from regular food intake, so taking multivitamin pills can help these individuals meet their nutrient needs.

Pregnant women and older adults may also experience lower appetites that make it hard to consume enough food. Again, in this case, consuming multivitamins can help fill the nutrient gaps [19] [20].

Supporting Overall Health

When you switch to the Carnivore Diet, your body needs time to adjust. At first, you might have some issues like constipation, which is normal. But multivitamins and other supplements can help you boost nutrient absorption and support gut health [21].

If you think your body lacks certain vitamins, like vitamin D, which is common these days, you can get a test to be sure. Then, you can start adding multivitamins to your Carnivore meal plan after consulting a healthcare professional.

If you’re prescribed multivitamins, these 5 brands can be good options for including a multivitamin on Carnivore Diet.

NHANES Report on Vitamin D Deficiency

According to data from the National Health and Nutrition Examination Survey (NHANES), approximately 41.6% of adults in the United States are vitamin D deficient.
