What are Vitamins and What Role Do They Play in the Body?

Every living organism requires different vitamins. For instance, humans have to get vitamin C from the diet, whereas dogs can synthesize all the vitamin C they require. Most vitamins are necessitated by food because the body either does not synthesize them or synthesizes them in minimal amounts. Vitamin D is not adequately present in food for humans. The human body produces this vitamin when exposed to sunlight, and this is the best source of vitamin D. There are different vitamins with different functions in the body, and an individual needs each in different amounts to keep them healthy. In this article, Porfiro has explained what vitamins are, what they do, and from which foods a person can get them.

What is vitamin?

Vitamins are organic substances present in small quantities in nature in foods. Inadequate intake of any specific vitamin may lead to specific health disorders. A nutrient is organic; hence, a vitamin contains carbon. It is an organic substance the body gets from food. Presently, there are 13 recognized.

Fat-soluble and water-soluble vitamins

Vitamins are two kinds; soluble in fat or water. We explain both types below:

1. Fat-soluble vitamins: Vitamins A, D, E, and K are fat-soluble. The body stores fat-soluble vitamins in fatty tissue and the liver, and these stores can last for days and sometimes months. Dietary fats help the body absorb fat-soluble vitamins through the intestinal.
2. Water-soluble vitamins: Water-soluble vitamins do not linger in the body for a long period and are even excreted by the body’s urine. For this fact, people need to obtain a regular supply of water-soluble vitamins compared to the fat-soluble ones. All the B vitamins and Vitamin C is water-soluble.

13 Types of Vitamins

Below, you will learn about each of the currently known vitamins:

Vitamin A

• Chemical names: Retinol, retinal, and four carotenoids, including beta-carotene.

• Good sources: Natto, leafy greens, pumpkin, figs, and parsley.

Vitamin supplements

Many people worldwide take vitamins and other supplements, even though these supplements are not necessary or helpful. A well-balanced and varied diet with plenty of fruits and vegetables should provide all the necessary vitamins.

The Department of Health and Human Services updates its guidelines on the best ways to get sufficient nutrients from the diet. In some cases, this would involve fortified foods and supplements, which may be suitable for pregnant women, people on limited diets, and those with certain health conditions.

Additionally, any user of supplements should avoid ingesting a dose higher than the maximum dosage recommended; studies have proved that too much intake of any vitamin may cause problems. Secondly, some drugs have been found to interact with the vitamin supplements. Generally speaking, one must consult with their doctor before using any dietary supplement.

When should we take vitamins?

There is no scientific evidence indicating the best time of day to take vitamins. It is very important to consume them consistently. However, taking certain vitamins at a specific time may reduce the risk of side effects. For example, depending on the type of vitamin, taking the supplement with food can enhance its absorption in the body and improve its overall health effects. The following article explains the ideal conditions for taking various vitamins.

Is timing important for taking vitamins?

Different vitamins work in various ways. This means that some have specific considerations regarding how they should be taken and whether individuals can eat food with them. Although research provides several recommendations to avoid side effects, science generally does not support any specific advice for taking vitamins at certain times. More importantly, individuals should not interrupt their daily supplement intake, especially if they are managing a deficiency.

In general, it is better to avoid supplements and obtain sufficient nutrients from a balanced diet. However, when vitamin supplements are necessary, individuals should be able to incorporate them properly into their routine. The timing for taking supplements is largely flexible. The following sections discuss different types of vitamins and the best times to take them.

Timing for Taking Water-Soluble Vitamins

The human body does not naturally produce or store water-soluble vitamins. Therefore, people must obtain these vitamins from animal and plant sources, and sometimes supplements. Types of water-soluble vitamins include vitamin C and most B vitamins.

Optimal Time for Vitamin C Consumption

Taking the recommended amounts of vitamin C at any time of day is safe. It naturally occurs in various plant products, including orange juice, grapefruit, and lemon. Since the body does not store vitamin C, individuals should consume it daily, ideally in small doses throughout the day.

Timing for Various B Vitamins

People tend to take B vitamins to boost energy and reduce stress. There are eight different B vitamins, each with a distinct role in the body. The types of B vitamins mentioned earlier include:

• Thiamine
• Riboflavin
• Vitamin B-6
• Niacin
• Biotin
• Vitamin B-12
• Folic Acid
• Pantothenic Acid

Generally, taking multiple B vitamins together is safe. Some companies also offer vitamin complexes that combine the daily amounts of each B vitamin. Due to their energy-boosting capabilities, the best time to take B vitamins is after waking up. Additionally, recent research suggests that vitamin B-6 may potentially interfere with sleep and cause vivid dreams. To avoid this adverse effect, individuals may want to take them earlier in the day. While B vitamin supplements can be safe for consumption, obtaining these nutrients from food sources is highly beneficial.

Timing for Taking Fat-Soluble Vitamins

Fat-soluble vitamins are essential in small doses. However, consuming high doses of fat-soluble vitamins can be harmful or toxic to an individual’s body. Cooking food does not eliminate fat-soluble vitamins. Typically, a person receives all the fat-soluble vitamins they need through their diet and does not require supplementation. Some examples of fat-soluble vitamins include:

• A
• D
• E
• K

Fat-soluble vitamins dissolve in oil. Therefore, individuals who need to supplement fat-soluble vitamins should take them alongside meals to enhance absorption. However, most people who consume a balanced range of nutrients obtain sufficient fat-soluble vitamins from their regular diet and likely do not need to take supplements separately.

Vitamins During Pregnancy

Pregnancy vitamins are fully packed with nutrients required during pregnancy. Individual needs vary, so the best vitamins taken during pregnancy will differ for different women. Prenatal vitamins will ensure that your body receives all necessary vitamins and minerals to ensure a healthy pregnancy. They support the growth and development of the fetus and inhibit nutritional deficiencies in both the fetus and the pregnant person. Most prenatal vitamins give a combination of vitamins and minerals including:

Vitamin B12:

• It is an essential vitamin which prevents neural tube defects such as:
• Spina bifida: incomplete closure of the infant’s spinal cord
• Anencephaly: a birth defect in which the infant is born without portions of its brain and skull
• Encephalocele: is the condition in which membrane containing part of the brain protrudes through an opening in the skull.

Vitamin B9 or Folic Acid:

This vitamin also prevents NTDs. Medical experts suggest 400 micrograms of folic acid every day before pregnancy and at least through the first trimester. A 2019 study has suggested a possible link between continued folic acid supplementation during pregnancy with healthy cognitive development in infants. The U.S. Preventive Services Task Force recommends that women of child-bearing age considering pregnancy take 0.4 to 0.8 mg of folic acid each day before conception.

In a similar way, the National Institute of Child Health and Human Development recommends that women take prenatal vitamins daily, especially with folic acid. Such prenatal vitamins combine folic acid with another nutrient such as iron or calcium, and persons in this situation should be put on these under medical supervision.

Iron:

This mineral is essential, especially during pregnancy, to avoid the state of fatigue or even anemia. Your doctor may recommend iron supplement medication to pregnant women who are anemic or carrying twins.

Calcium:

This nutrient plays an important role in keeping your bones and teeth healthy-carrying out the correct nutrition in dental care-in particular, during the different periods of life.

Vitamin D:

Regulation of calcium and phosphate levels makes sure your teeth, bones, and muscles are healthy.

Vitamin C:

This vitamin protects the body’s cells from damage.

Considerations:

A 2019 review shows that taking some prenatal vitamins on an empty stomach can cause indigestion and nausea. If a prenatal vitamin makes feelings of nausea worse, the mother may take it with a small amount of food. Although the review stated that this often does not happen, taking prenatal supplements with food can lower the risk for nausea. There are various types of prenatal vitamins, and a woman should be cautious while selecting the type of vitamin during pregnancy.

Although many are alike, each can have different levels of nutrients and ingredients and the FDA does not monitor supplements. It is important for women to speak with their doctor prior to initiating prenatal vitamins for recommendations and guidance. High levels of vitamins can be toxic to either mom or her fetus. And most importantly, women should not take two different types of prenatal vitamins together.

When to See a Doctor

An individual may want to seek professional advice before purchasing prenatal vitamins. According to a 2016 study, 25 top prenatal vitamins available over-the-counter in the United States did not contain the required daily amount of choline. A healthcare professional can explain what a supplement should contain to ensure that each individual meets their dietary recommendations during pregnancy. Additionally, if any side effects occur while taking the supplement, the individual should consult their doctor. A common side effect of prenatal supplements is constipation. Some prenatal vitamins contain non-constipating iron to address this issue. Other potential side effects of supplements include:

• Abdominal cramps
• Bloating
• Gas
• Delayed bowel movements
• Hair loss
• Itching or peeling skin

What is the Most Effective Prenatal Vitamin?

The best brand of prenatal vitamins depends on individual needs. Someone with existing health conditions or a restricted diet may have specific nutritional requirements. An individual should be able to take their vitamins easily. Gummies and soft gels may be easier for those who have difficulty swallowing large pills. A pregnant individual can ask their healthcare provider for suitable recommendations.

What key nutrients should prenatal vitamins contain?

Generally, a doctor may advise taking one or multiple prenatal vitamins, but an individual brand is not usually recommended unless a person has certain nutritional needs. Though most prenatal vitamins contain three necessary nutrients such as iron, iodine, and folic acid, different prenatal vitamins may have different amounts of the rest of the nutrients. Such diversities in the content make some brands of prenatal vitamins more suitable for some individuals compared to others. A doctor can recommend a certain type of prenatal vitamin depending on one’s needs.

What Prenatal Vitamins Do Doctors Prescribe?

The general view of the doctors concerning the matter is that they don’t actually recommend any brand of vitamins. However, some great nutrients to have in these supplements include:

• Vitamin C
• Vitamin D
• Vitamin K
• Thiamine (Vitamin B1)
• Vitamin B6
• Folate (Vitamin B9)

What are the Best Prenatal Vitamins for Those Suffering from Recurrent Miscarriages?

It was concluded from studies that the consumption of any form of vitamin before or during pregnancy did not reduce the rate of miscarriage, which, in other words, means vitamins are not very significant in this regard. However, there is some evidence that multivitamins containing iron and folate may reduce the risk of stillbirth. This issue can be brought into consideration by a healthcare provider for the pregnant individual.

What You Should Know About Fertility Supplements

Treating infertility can be challenging. Modern medical techniques can sometimes be effective, but they may be costly, and success rates can vary. Some individuals dealing with infertility seek alternatives to medical intervention to help them conceive. They may try to use supplements that claim to enhance fertility in men, women, or both.

While there are numerous claims about the benefits of such supplements, it is essential to remember that the U.S. Food and Drug Administration (FDA) has not reviewed most supplements for their effectiveness in clinical studies, and even if a study has been conducted, it has often been small in scale. This article will further explain fertility supplements, including their potential risks, as fertility issues are currently a significant concern and hold special importance.

However, PORFIRO reiterate that the content of this article is intended solely for informational purposes and does not constitute any recommendations, diagnoses, or treatment methods for any case. This must necessarily be done by a qualified physician, but being informed about the conditions is very important, and this is the goal of our platform—to empower our audience with knowledge and awareness.

Types of Fertility Supplements

Common types of fertility supplements include:

• Acetyl L-Carnitine (ALC): This is an antioxidant. In a scientific study conducted in 2018, researchers aimed to find out the effect of ALC on issues affecting women’s fertility, such as polycystic ovary syndrome, or PCOS, endometriosis, and amenorrhea or pain during intercourse. The review showed that ALC is promising in supporting the medical treatment of women’s fertility problems. A more recent study, on the other hand, looked into the role of antioxidants, among them ALC, in sperm quality. The authors were able to confirm the action of antioxidants on sperm motility.
• Vitamin E: Vitamin E, by virtue of its antioxidant action, might increase sperm motility, according to a study conducted in 2018, and hence is able to improve male fertility. However, there is very little research into the possible benefits of vitamin E supplementation in women with fertility problems.
• Folic Acid: According to researchers, folic acid may help women conceive and sustain pregnancy. The authors noted that further research was needed to determine the magnitude of the effects of folic acid and other nutrients as treatments for women’s fertility. For men, a 2017 review of previous studies found that folic acid combined with zinc improves sperm quality.
• Coenzyme Q10: This helps in energy production in human cells. Recent researches related to this enzyme for treating infertility have also been quite encouraging. A 2018 study reported that CoQ10 could improve ovarian response to stimulation in women undergoing in vitro fertilization (IVF). The pregnancy rate in women taking CoQ10 was more than in the control group, although the difference did not attain statistical significance. The researchers concluded that CoQ10 had promise but more studies were needed to determine its efficacy.
• Vitamin C: This might help in male fertility. A 2016 study showed overweight men taking Vitamin C improved their sperm count and motility.

Do These Supplements Work?

Some research suggests that fertility supplements can be helpful, but other research does not show any effect. Some studies indicate that excessive use of therapeutic antioxidants by men actually reduces their fertility. Much more research is needed to understand which fertility supplements really work.
For some, the addition of supplements may be added to lifestyle changes such as weight loss, reduction of alcohol and smoking that may enhance their likelihood of conceiving. The use of supplements alone is not a guarantee to succeeding in pregnancy.

Risks

Some fertility supplements can also interact with other medications a person is currently taking. For example, folic acid can interfere with anti-seizure drugs and those treating parasitic infections, while taking vitamin E with anticoagulants, weight loss drugs, and bile acids soothing medications can lead to toxic side effects. High dosages of supplements may also be a cause for side effects, which include the following:

• Nausea and vomiting
• Hives
• Blurred vision
• Increases the danger of cardiovascular disorders while consuming folic acid
• Increases the danger of tumorigenesis while using folic acid
• Headache
• Necrotizing enterocolitis: an often-fatal birth defect

Questions to the Doctor?

People should not take supplements to enhance fertility without consulting a doctor about possible risks and benefits. The doctor should be aware of the medical history and previous conditions, if any, that the person has had. Questions to be asked include whether the supplement interacts with other medications and whether there is a risk of overdose.

Other Supplements

The human body requires both vitamins and minerals to operate. Like vitamins, minerals are available as supplements. There are many claims about the health benefits of mineral supplements. Some examples of minerals include:

• Iron
• Calcium
• Magnesium
• Zinc

Mineral supplements should be taken with caution, always bearing in mind their pros, especially when the individual may have a deficiency, and that most basic studies on supplements have been observational and much laboratory work has been very unreliable. Secondly, one can easily overdose on one type of mineral. A person with these needs should take in minerals daily through the consumption of food. People who are taking supplement minerals without any food will face some possible side effects of stomach aches due to the drugs.

What are the symptoms of vitamin deficiency?

Vitamins help in body growth and ensure that all its systems work properly. However, when vitamins are not taken in adequate amounts or when the body cannot absorb them, there is a deficiency. The deficiency can manifest through a number of symptoms that may range from mild to severe. This section can present the common deficiencies of each vitamin, symptoms and signs of each deficiency, how to diagnose and treat these deficiencies, and when to consult a doctor about such deficiencies. Many of the symptoms above have already been discussed, but all those are very crucial to get much attention.

Symptoms of Vitamin A Deficiency

According to the 2022 review, vitamin A deficiency is relatively widespread in developing countries and is one of the leading causes of eye pathologies. The clinical symptoms of vitamin A deficiency can be manifested by the following:

• Dry eyes and eye dryness
• Bitot spots and conjunctival dryness
• Night blindness
• Keratomalacia-clouding of the cornea-and permanent blindness

The following conditions are at risk for vitamin A deficiency:

• Inflammatory bowel disease
• Chronic gastrointestinal infections
• Cirrhosis
• Pancreatic insufficiency

Thiamine (B1) Deficiency

Early symptoms of B1 deficiency may include:

• Loss of appetite
• Irritability
• Short-term memory problems

Thiamine deficiency can affect the cardiovascular, nervous, and immune systems, such as:

• Wet beriberi, which impacts the cardiovascular system
• Dry beriberi, which affects the nerves
• Wernicke-Korsakoff syndrome, where walking, mental status, vision, and eye health change

With prolonged deficiency of this vitamin, individuals may experience:

• Loss of sensation in limbs
• Symptoms of heart failure, including swelling in the hands or feet
• Chest pain related to ischemia
• Feelings of dizziness
• Double vision

• Peripheral neuropathy

Severe deficiency may present with seborrheic dermatitis and anemia. However, these symptoms may also be seen in other health conditions; hence, the diagnosis of vitamin B6 deficiency is quite difficult for clinicians.

Biotin (B7) Deficiency

Biotin deficiency presents with a series of signs and symptoms that include neurological and cutaneous changes. Neurological manifestations may include:

• Hypotonia
• Seizures
• Ataxia
• Paresthesia of limbs
• Delayed growth in children
• Optic atrophy
• Sensorineural hearing loss

It also causes gastrointestinal manifestations, which include:

• Nausea
• Vomiting
• Loss of appetite

Among the other results of the lack of biotin within an organism’s system are ketoacidosis, lactic acidosis, and organic aciduria.

Vitamin B9

Vitamin B9 deficiency can cause a lot of problems, including the following:

• Fatigue

• Fatigue
• Palpitation
• Pale skin
• Loss of weight
• Numbness and tingling of the limbs

Symptoms of Vitamin C Deficiency

General signs of deficiency of vitamin C may include:

• Gingivitis, a form of gum inflammation and bleeding
• Periodontal disease, or gum disease
• Loss of teeth
• Petechiae of skin
• Ecchymosis or skin bruises
• Hyperkeratosis, or thickened skin
• Alopecia, or hair loss
• Corkscrew hair, due to twisted hair shaft caused by impaired collagen production

Hair changes may present as swan neck hairs, which are hair shafts that bend at several points due to weakened hair follicles. Follicular bleeding is bleeding from the tissues surrounding hair follicles. The nail changes include koilonychia and splinter hemorrhages.
If any of the above symptoms are present, one should seek a doctor’s opinion. The doctor will be able to say whether the symptoms are because of vitamin C deficiency or other causes. Lack of enough vitamin C intake is also called scurvy. It is a very rare disease. It is curable with timely treatment. The symptoms and signs of scurvy may include those previously discussed, as well as:

• Joint ache
• Muscle ache
• Hemarthrosis or bleeding in joints
• Muscle hemorrhages
• Bone bruising

Symptoms of Vitamin D Deficiency

Most individuals with vitamin D deficiency do not have any symptoms. Their deficiency is mild and has been there for several years, presenting them only with the following issues:

• Low levels of calcium, also known as hypocalcemia
• Hyperparathyroidism or high parathyroid hormones leading to the increased risk of:
• Osteoporosis
• Fractures

Chronic and Severe vitamin D deficiency leads to:

1. Secondary hyperparathyroidism, including the following: Fatigue/ Muscle cramps/ Weakness/ Osteoporosis, leading to bone fractures
2. Children with vitamin D deficiency may experience: Irritability/ Lethargy/ Growth delays/ Bone changes/ Fractures

It is at this point that the caregiver must seek advice from the doctor if any of the symptoms are identified in a child for diagnosis and effective treatment.

Symptoms of Vitamin E Deficiency

Possible symptoms of vitamin E deficiency include:

• Ataxia
• Difficulty looking upward
• Hyporeflexia, which is the loss of skeletal muscle reflexes

Severe symptoms may include:

• Blindness
• Dementia
• Cardiac arrhythmias

Less common symptoms include muscle weakness and contraction of the visual field.

Symptoms of Vitamin K Deficiency

Lack of vitamin K may lead to:

• Bleeding disorders
• Impaired bone growth
• Cardiovascular diseases

Vitamin K deficiency can cause bleeding at injection sites. Newborns with low levels of vitamin K who do not receive prompt treatment are at risk for bleeding due to vitamin K deficiency, which can lead to excessive bleeding. Individuals should consult a healthcare professional if they observe any of these symptoms. The doctor can help prevent potential complications from vitamin K deficiency.

Diagnosis

Since the symptoms of vitamin deficiency may overlap with other conditions, it is important to obtain an accurate diagnosis from a doctor rather than relying on self-diagnosis. To diagnose a vitamin deficiency, the doctor considers the individual’s symptoms and signs during a physical examination. In most cases, a blood test is ordered to measure the individual’s vitamin levels. Not all vitamin levels can be easily tested in standard clinical settings. In some cases, the doctor may refer the individual to a specialist.

When to Contact a Doctor

If an individual experiences any of the symptoms mentioned above, it is advisable to contact a doctor. If left untreated, some deficiencies can lead to long-term complications. Timely diagnosis and treatment can help prevent serious complications.

Finally, Porfiro in this article aimed to provide a comprehensive overview of the essential vitamins necessary for the body. Since the body is one of the most precise systems in the universe, any imbalance in even a small component can ultimately have a significant impact on the functioning of this system. It is reiterated that any specific recommendations, interventions, identifications, or prescriptions for balancing vitamin levels in the body should fundamentally and necessarily be conducted by a specialist physician. What has been mentioned in this article serves only as informative guidance for Porfiro’s valuable audience so that if they encounter any specific condition, they know that thorough follow-ups are necessary for maintaining their health.
