Intravenous vitamin formulations:
It
 is a method of giving high concentrations of vitamins and minerals 
directly into the bloodstream, allowing rapid absorption of higher doses
 thereof than if a person obtained them through food or nutritional 
supplements. It has spread widely in the recent period and its types 
have varied.
The Mechanism:
These
 formulations are given through a small tube inserted into a vein, and 
are called a “vitamin cocktail.” The types and proportions of vitamins 
in these formulations vary depending on their purpose.
Efficacy of intravenous vitamin formulations:
It
 is commonly used intravenously for people who cannot get enough 
vitamins and minerals, either because they cannot eat enough food, or 
because they have a medical condition that impedes the absorption of 
nutrients within the body, but:
- Few studies have been 
conducted testing the effectiveness of these formulations in people who 
do not have vitamin or mineral deficiencies, and none have confirmed the
 effectiveness of these formulations.
- The evidence for the use 
of these formulations in the treatment of patients with malabsorption 
problems, burns, or serious infectious diseases is unclear.
Accordingly,
 the effectiveness of these formulations is based on rumors and people's
 individual stories, which is not considered strong evidence for its 
use.
Possible side effects of intravenous vitamin formulations:
- It can make the body more susceptible to infection and can cause blood clots and burning at the injection site.
- Exposing
 the liver and kidneys to large amounts of vitamins can put them under 
great pressure, leading to problems and disruption of their functions.
- Injecting
 a high dose of the vitamin with nutrients can increase the fluid load 
in the blood in patients with high blood pressure or heart disease; 
Which exposes them to temporary and sometimes permanent kidney or heart 
damage.
- Giving these combinations too quickly may result in low blood pressure, dizziness, and fainting.
- Taking high doses of some vitamins and minerals has negative side effects and increases the risk of developing some conditions.
Recommendations:
Vitamins
 and minerals are nutrients that the body needs in small quantities to 
function properly and remain healthy. They are found naturally in 
various foods, so it is recommended that most people get all the 
nutrients they need by following a varied and balanced diet. Eating a 
wide range of healthy foods helps meet nutritional needs, and also 
provides additional benefits (such as: dietary fiber and antioxidants).
Current
 scientific evidence has not confirmed the health effects of using 
intravenous vitamin formulations in healthy people, and the safety of 
their use is unclear.
Examples of some foods that enhance the body's need for certain vitamins and minerals:
- Vitamin E: found in nuts, green leafy vegetables, and fortified grains.
- Folic acid: found in spinach, lettuce, broccoli, peanuts, avocados, enriched grain products, and fortified breakfast cereals.
- Vitamin B6: Found in bananas, beef, fish, chicken, fortified cereals, whole grains, nuts, and beans.
- Vitamin B12: Found abundantly in milk, dairy products, meat, fish (especially salmon), poultry, and eggs.
- A
 form of vitamin A, known as beta-carotene, found in yellow and orange 
fruits (such as cantaloupe and mango), and green leafy vegetables (such 
as spinach).
- Iron: It is found in red meat (such as: beef and 
chicken), seafood such as fatty fish, oysters, and eggs, and in beans, 
and dark green leafy vegetables (such as: spinach).
