Are you looking for a way to kick your metabolism up a notch? From vitamin B12 to vitamin D, many vitamins can help promote a healthier metabolism. 

This blog will explore six vitamins essential for metabolic wellness and how they can improve your overall health. We’ll also discuss the differences between oral supplements and IV vitamin treatments.

Vitamin B12

A water-soluble vitamin, B12 plays a vital role in maintaining metabolic health by assisting in regulated red blood cell production, nerve function, the production of DNA, and the breakdown of fats and carbohydrates.

Vitamins of animal origin, like those found in fish, meat, poultry, eggs, and dairy, can efficiently restore B12 levels. Those following a vegan diet may be at risk for vitamin B12 deficiency since this diet does not include any animal products. Additionally, individuals with absorption issues may not be able to obtain enough vitamin B12 from food alone, requiring supplementation to meet their needs.

Vitamin D

Vitamin D plays an essential role in many body processes. It helps your body absorb and process calcium, which contributes to strong bones and teeth. This vitamin may also help reduce the risk of certain types of cancers and autoimmune diseases.

Getting enough vitamin D1 is essential for people of all ages, with direct exposure to sunlight remaining the most straightforward method to provide your body with vitamin D. However, this is only sometimes possible, depending on the time of year or where you live. Getting enough vitamin D from food sources or supplements is vital.

Foods like fatty fish, eggs, fortified milk, orange juice, and mushrooms are all great sources of vitamin D. If you cannot get enough vitamin D from food sources alone, consider taking a supplement.

Riboflavin2 is an essential vitamin for maintaining a healthy metabolism. This vitamin, also known as vitamin B2, helps to convert food into energy. B2 is plentiful in beef liver, almonds, and spinach. A riboflavin supplement can help support your body’s ability to turn food into energy.

Vitamin B6

B6 is an essential vitamin for metabolism and maintaining optimum health, necessary for the proper functioning of over 100 enzymes that aid in the breakdown of proteins, fats, and carbohydrates. B6 also helps to produce hemoglobin, the oxygen-carrying pigment in red blood cells. The body also needs vitamin B6 to synthesize neurotransmitters and hormones and regulate homocysteine levels, an amino acid linked to heart disease.

Good sources of vitamin B6 include fortified cereal, beef liver, salmon, bananas, spinach, potatoes, and chickpeas.


Niacin, or vitamin B3, is a crucial vitamin that helps to keep our metabolism functioning properly.3 Influential in energy production, niacin helps break down carbohydrates, proteins, and fats in the body. It is also critical for healthy nerve and skin function and hormone production.


Vitamin B1, also known as thiamine, is directly involved in energy production4 and aids in the breakdown of carbohydrates, fatty acids, and amino acids, making it necessary for cellular metabolism. Additionally, thiamine is essential for proper brain and nerve function.

Oral Supplements vs. IV Treatments

Oral supplements, such as pills and capsules, are typically more affordable and easier to take regularly. Many brands and formulations are available today for those who prefer to take supplements orally. Supplements also have the advantage of being available without a prescription.

However, IV treatments are more effective in delivering the vitamins directly into the bloodstream for immediate use. Rapid absorption into the body can be an excellent option for those who need quick relief from vitamin deficiencies or require higher doses of specific vitamins than with oral supplementation.


Overall, oral supplements and IV treatments can effectively deliver vitamins to the body to help improve your metabolism. Always consult your doctor before taking any supplements or beginning an IV treatment. You can discuss this with your doctor to determine which option is right for you based on your health and lifestyle.

Vitamin D Shots - Frequently Asked Questions

Can you take too much vitamin D?

Yes, it is possible to take too much vitamin D. Vitamin D is a fat-soluble vitamin, which means that it can build up in the body and potentially lead to toxic levels if it is consumed in large amounts. Vitamin D toxicity can cause hypercalcemia, a buildup of calcium in your blood. This condition can cause symptoms such as weakness, nausea, vomiting, frequent urination, kidney problems, and more.

How often do you need vitamin D shots?

Frequency of treatment depends on individual circumstances such as the severity of vitamin D deficiency, medical history, and other factors. However, most people may receive 1 – 3 shots over the course of a year.

Are vitamin D shots better than oral supplements?

Yes. Because vitamin D shots are given intramuscularly, the ingredients bypass your digestive system so that the full dose is available to your body for maximum benefits. Vitamin D shots are rapidly available for your cells to use.

What happens if you don’t treat vitamin D deficiency?

Not treating vitamin D deficiency can cause rickets, a rare but treatable condition that causes fatigue, frequent illnesses, depression, and impacts bone and muscle health. In children, vitamin D deficiency can impact normal growth and development.
