About the Test
The High Fat Diet Vitamin Deficiency Panel measures the levels of the following 8 vitamins and minerals in your blood: vitamin B1, vitamin B6, vitamin B7, vitamin B12, calcium, iron, magnesium, and phosphorus.
Identifying and correcting nutritional deficiencies is an important step toward better health. Your body does not produce most vitamins and minerals, so you must get them through food or supplements. How nutrients work in your body is influenced by more than just what you eat. These factors include genetics, age, health conditions, medications, metabolism, and how well your body absorbs nutrients.
Dietary restrictions may make it difficult to get the nutrients your body needs. Having these nutrients tested helps you and your doctor decide if you need to modify or supplement your diet.

FAQs
No. Both low-carb and high fat diets (like keto) limit carbohydrates like grains and starchy vegetables. Keto diets allow very few carbs, and you may have to eat fewer fruits and vegetables. Keto diets require a lot of fat, which makes your body use fat for energy instead of carbs (a process known as ketosis).
Not necessarily. Many of the micronutrients in this panel are mainly found in carbohydrate-rich foods avoided on a high fat diet. However, if you consume enough healthy proteins, nutrient-rich vegetables, nuts, and seeds, you may not have all or any micronutrient deficiencies. It’s important to get tested so you know which nutrients you are not getting enough of in your diet. Then, you can talk with your doctor about what changes to make to your diet or what supplements to take.
It’s important to get tested for any deficiencies before starting on a high fat/low-carb diet This is to identify if you are already deficient in any of these nutrients, as you could become more deficient and further impair your health when you eliminate certain foods from your diet. Addressing any deficiencies and discussing them with a doctor may help you make the transition to a high fat/low-carb diet more successful.
The best way to get essential vitamins and minerals is from food because they are in their natural form. However, if your body cannot absorb certain nutrients properly, or you are not able to get enough of them through your diet, then you may consider taking a supplement for that nutrient.
While it is unlikely to get too much of a micronutrient if you are taking a supplement, getting too much, known as vitamin toxicity, is possible. It's recommended to confirm a deficiency through testing and talk with your doctor prior to taking supplements.
Water-soluble and fat-soluble vitamins differ in how they are absorbed by the human body.
A water-soluble vitamin dissolves in water and is easily absorbed by the body. Your body does not store these vitamins for long, so any extra will be eliminated in your urine. Because of this, it's important to consume them every day.
A fat-soluble vitamin dissolves in fats and oils and is absorbed with the fats you eat. Your body stores any extra in your liver or fatty tissues. Because of this, you don't need to consume them every day.
Antioxidants are substances that can prevent or slow damage to cells caused by oxidative stress. They interact with toxins called free radicals, to minimize their damage. Antioxidants can help prevent diseases like cancer and reduce your risk of heart disease.
An enzyme is a protein that helps to start, or speed up, a reaction in the body. A coenzyme is a non-protein molecule that helps an enzyme to perform that reaction.
