Vitamins and minerals are inherently pure compounds and, therefore, should not interfere with ketosis. It's completely safe to take vitamins while following a ketogenic diet without getting kicked out of ketosis. Vitamins alone don't alter ketosis, unless they contain a lot of added sugars, such as those found in vitamin gummies or flavored vitamin supplements. However, the effect is not as clear as it seems.
It's not uncommon for some people to experience digestive discomfort or allergic reactions when taking vitamin supplements. However, taking a multivitamin supplement involves taking synthetic nutrients, which is not the same as having a healthy balance that you get from a few naturally occurring nutrients. You don't have to worry about multivitamins having too many net carbs and getting you out of ketosis. Just because you eat fewer carbohydrates than before doesn't mean you're automatically lacking in vitamins and minerals.
Therefore, it is always advisable to take a vitamin in pill or capsule form or, at the very least, to make sure that it does not contain added sugars on the nutrition label. Most of the essential vitamins and minerals you buy in pill form are pure compounds and don't alter ketosis. However, other ingredients added to a mineral or multivitamin supplement can affect blood glucose levels. Although it's rare to be deficient in this vitamin, an insufficient intake can increase the risk of heart disease and osteoporosis.
A ketogenic diet won't necessarily result in vitamin D deficiency, but because vitamin D deficiency is so common, vitamin D supplementation probably won't harm you. This is a list of vitamins that will keep you healthy on a low-carb diet, in addition to the foods that contain them. First of all, let me tell you that vitamins and supplements should complement and support a balanced diet. What most people don't know is that vitamin D is a steroid hormone that is produced from cholesterol when the skin is exposed to the sun.
Remember that they are eliminated at a greater rate by the kidneys as insulin levels drop when starting the diet, so electrolytes are especially important for beginners to the ketogenic diet (or for those who resume it after a break). That said, many of the vitamins available at your local store often use fillers that may contain trace amounts of carbohydrates.
