The Best Vitamin C Supplements in 2021

We have already covered our criteria in the previous section. It is now time to find out more about the vitamin. Here are some details about the benefits of vitamin C, recognising it, what signs you need, best forms and other important aspects.

Vitamin C

Vitamin C, also known as ascorbic acid, is one of the most well-known vitamins. Vitamin C is an essential nutrient that can repair body tissues, develop immunity, and protect neuronal tissue.

James Lind, a Scottish doctor, was the first to recognize the effects of organic vitamin A. He discovered that citrus fruits could be used in treating scurvy (a common condition among sailors at the time). The compound's name was not known at the time. It was discovered by Dr. Albert Szent-Gyorgyi in 1928. He named it hexuronic acids. Walter Haworth changed the name to ascorbic acid in 1932.

What is Vitamin C?

In a vitamin C definition, it is important to mention that it is water-soluble, meaning it dissolves when it is liquid. These compounds are easy to excrete through the urine if consumed in excess. This is why vitamin C overdoses are very rare.

The body can only store 300mg to 2,000mg of vitamin C for a short time. Red blood cells, saliva and plasma, contain lower levels of vitamin C.

Vitamin C Functions

Most people are familiar with vitamin C's antioxidant properties since the supplement market advertised all top-rated products. The vitamin's main function is to protect and stabilize the body tissue.

Here are the main functions and benefits of vitamin C, without going into too many details:

L-carnitine synthesis: This compound is crucial in L-carnitine manufacturing. This amino acid plays a crucial role in the burning of fat and converting it to energy.

Neural protection: Mature neurons require a lot of the compound to protect themselves against the stress caused by their activity.

Cutaneous enzyme defence: It works in conjunction with vitamin E to capture and eliminate free radicals. Your skin will appear younger for longer.

Vitamin C can be used to increase intercellular matter production. Regular consumption of vitamin C tablets can improve tissue binding and stability.

Ascorbic acid can absorb iron. It is well-known for its ability to bind iron molecules and aid the body in absorption.

Vitamin C helps to inhibit the growth of age spots and skin chloasma.

Protecting the cardiac system: Some data suggest that vitamin C could have an antioxidant effect against bad cholesterol, preventing it from building up in the arteries.

The formation of collagen: By supplementing with different forms of vitamin A, you can increase your body's production and regulation of collagen (the compound that affects hair, joints, and skin health). Ascorbic acid is a cofactor in this situation since it stabilizes the amino compounds necessary for collagen synthesis.

Research suggests that to develop a healthy brain, you need a lot of vitamin C.

Experts are still investigating the compound's potential functions in other areas.

Dosages

Knowing the best way to consume vitamin C is only part of the equation. It is important to remember the recommended daily intake of vitamin C.

Over the years, the RDA for this compound has changed. The original recommendation was to take 10 mg daily to prevent scurvy symptoms. The RDA is between 65 and 100mg per day to reap the full benefits of ascorbic acids. However, the current average dosages are close to ten times greater.

Professionals are still struggling to determine the best dosage for everyone.

They all agree that fresh fruits and vegetables are the best way to get vitamin C. People who eat healthily are likely to consume between 200 and 250 mg of vitamin C per day. These people may also live longer and have fewer cardiovascular problems.

Absorption

Vitamin C can be administered intravenously. However, it is more commonly consumed as a food or oral supplementation. The absorption rate for Vitamin C is high, mostly in the intestinal tract, and can reach 90% when taken in small quantities throughout the day.

High-concentration supplements can be less effective because, when taken in higher amounts (between 1,000 and 2,000 mg), the absorption rates drop to around 40%, and excess urine will likely be excreted within a few hours. The best vitamin C pills won't have the highest concentration.

Vitamin C Deficiency, Groups at Risk

Vitamin C deficiencies can occur in two phases. The first stage is often described as fatigue and then followed by metabolic imbalances, which may cause weight gain or obesity.

Even though it's rare in the US, the second stage can prove to be deadly. This condition is most common in people suffering from extreme malnutrition. It usually comes with the following symptoms:

Psychiatric disorders or problems: Your neuronal health may deteriorate when you don't eat enough vitamin C-rich foods and vitamin C capsules. This can lead to neurological problems ranging from paranoia to hypochondria to apathy.

Serious infections: Ascorbic acid plays an important role in the creation of enzyme compounds that fight infection. The lack of vitamin C can significantly increase your risk of getting different illnesses and infections.

Poor ascorbic acid supplementation may also cause dental problems. This can lead to weakening intercellular joints, which can cause teeth to fall out or gum inflammation.

People with vitamin C deficiencies are often weak and have difficulty gaining energy. This can lead to fatigue.

Anemia: The body may not absorb enough iron if it does not consume enough vitamin C. Vitamin C aids in absorbing iron.

Slowly healing wounds: Different types of vitamin C are necessary for the healing process. Ascorbic acid is a key component in collagen synthesis. It is important because, without it, wounds might not heal at all or heal very slowly.

While most Americans consume sufficient vitamin C not to suffer the above symptoms, certain groups are more susceptible to hypovitaminosis.

They are:

People with eating disorders: Those who have a poor self-image and don't supplement their diets with high-quality vitamin C tablets may be at risk.

People with restricted diets: These people can't eat certain foods and must follow a low-variety diet (particularly low in fruits and vegetables). Hypovitaminosis C may also be present.

Alcoholics: Excessive alcohol consumption has been linked with several nutritional deficiencies, including vitamin C deficiency.

Smokers: People who smoke regularly are 18% more likely to experience the side effects of low vitamin C.

Oral contraceptives are often used by women who have lower levels of vitamin C.

Interactions between Prescription Medicines and Other Drugs/Treatments

It is important to understand how prescription drugs and ascorbic acid can interact with each other to determine the best vitamin C supplement.

Vitamin C, for example, can increase the body's aluminium absorption when it comes in contact with aluminium-containing antacids.

The body's estrogenic activity increases in the case of estrogen-based contraceptives. Vitamin C may be able to decrease the presence of some antipsychotics. Ascorbic acid may also be able to decrease the side effects of chemotherapy in certain cases.

However, even the most effective vitamin C products can slow down eliminating certain drugs, such as paracetamol and aspirin.

Although this might be true, the effects shouldn't be too severe or pose a threat to your health.

Interactions with other types of supplementation

Most vitamin C products can be combined with other supplemental substances to enhance their effectiveness. You will get different results from different combinations. Here are some of the most popular combinations you should be aware of:

Combining vitamin E with vitamin A can increase antioxidant capacity and decrease cardiovascular risks like atheroma plaque oxidation.

Combining vitamin D with it: Apart from its increased antioxidant power, it can also promote tissue regeneration, improve bone health, and lower cardiovascular risk.

Vitamin C products combined with magnesium can improve collagen synthesis, enhance the appearance of the skin, and even prevent the skin from aging. You can improve your skin's health by looking for the best vitamin supplements for your skin.

Combination with L-carnitine: In this instance, vitamin C can boost the body's level of L-carnitine overall. This can help increase energy and increase your chances of losing weight.

Combining selenium with it: This combination increases ossification and can be used to prevent liver damage.

Many of the best vitamin C brands make products that can be combined with these combinations. This allows users to kill two birds in one. People are advised to purchase separate supplements to meet their individual needs, as the final results can be more or less identical.

Vitamin C-rich Foods -- The Best Source for Vitamin C

Although supplementation is always a good idea for most people, whole foods are still the best option as they contain many other vital nutrients in addition to ascorbic acid.

Side Effects and Benefits of Vitamin C

Consuming a diet rich in this compound will preserve your body's internal balance. It will also provide all of the benefits associated with regular consumption.

Vitamin C can be found in the body and:

  • Provide better cutaneous protection
  • You can heal wounds quicker

Negative effects aside, it is difficult to overdose on ascorbic acid in healthy individuals with functioning kidneys. All excess ascorbic acids are excreted during urination.

Although this is true, it is still not advised to consume more than 2,000 mg per day. Intestinal discomforts can occur if vitamin C pills are taken in excess. These could include:

  • Vomiting
  • Diarrhea
  • Difficult digestion
  • Stomach pain
  • Gastroesophageal reflux

People with kidney problems should consult their healthcare provider before taking ascorbic acid supplements.

Vitamin C Supplementation for Certain Groups

Although most people are fine with supplementing their diets with vitamin C, some precautions should be taken.

Before taking high-potency vitamin C products, the following groups should consult their doctors:

  • People suffering from certain enzyme or endocrine disorders
  • High levels of oxalate in the urine of people with high blood pressure
  • High iron levels in the blood of people with high iron levels

Supplementation may be beneficial for pregnant (and nursing) women. A physician should monitor Supplementation and give caution, even if the product is of high-quality vitamin C.

Vitamin C Supplements for People Who Need It

Although it is best to eat plenty of vitamin C, all people can take ascorbic acid supplements.

A good vitamin C supplement will be a huge help to smokers and people trying to lose weight. These supplements are recommended for people with anemia.

A positive relationship was found between vitamin C supplementation, lower blood pressure, and other scientific findings. This makes vitamin C a great option for people with hypertension.
