How We Ranked the Top Vitamin C Supplements

The market offers a wide range of vitamin C supplements, each of which claims to use the most potent dosage of the vitamin combined with an exemplary delivery system. Sadly, not each product you find in the market lives up to the hype. However, our research and ranking were based on various crucial factors, which guided us in sifting the best formulas from the worst. These factors were as follows:

Vitamin C Dosage

The goal of taking a vitamin C supplement is to get as much vitamin C as possible. Therefore, we compared the vitamin C dosages in the available products to help us get the best. Vitamin C is water-soluble, meaning your body can absorb as much as possible without any safety concerns, and the excess can be removed through the urine. The best vitamin C supplements should give you between 500% and 1000% of your recommended dietary intake (RDI) or vitamin C daily value (DV).


Some supplement manufacturers ensure maximum absorption of their products by the human body. For instance, Zenith Labs uses nanotechnology to shrink its vitamin C participles. This significantly boosts its absorbability.

Purality Health utilizes micelle liposomal technology to wrap vitamin C in a fat molecule, another technique for increasing its absorbability. While every manufacturer adds vitamin C to their formula, very few invest in unique delivery technology to guarantee users maximum absorption.

Doctor Formulated

Like most other supplements, the best vitamin C formulas are developed by registered dieticians (RDs) and medical doctors (MDs). For this reason, we considered the supplements created by the stated professionals instead of those created by marketing teams, among other unqualified developers. Moreover, DOs, PhDs, and authentic, experienced professionals make the best vitamin C formulas.

Manufacturer Reputation & Transparency

Some manufacturers have been in the market for many years, in which they have built an incredible reputation for creating high-quality products. However, some companies don’t pay attention to delivering quality products. Therefore, we paid more attention to the former and, further, those who were transparent about the sources of their ingredients.

Moneyback or Satisfaction Guarantee

Some manufacturers are confident with their products, which explains why they offer their consumers a moneyback or satisfaction guarantee. However, this is not the case with every manufacturer, which gives the former a competitive edge over their competitors. Providing a generous and honest refund policy indicates effective products, so our rank list comprises companies that offer them.

Complementary Ingredients

Besides the vitamin C dosage, we also ranked the formulas on our list based on the complementary ingredients used. To enhance the effectiveness of vitamin C in the body, some manufacturers included powerful additional antioxidants, vitamins, and minerals, making their products more powerful and effective.

Price and Value

Vitamin C is not rare, making it easy for anyone to create its supplements, especially with the proper knowledge, skills, experience, and resources. Therefore, it is unreasonable to price your products too high compared to your competitors when creating them is not as costly as what you charge your clients.

Besides, if you are charging a premium price, you should ensure premium products accompany it to match the two. As a buyer, you shouldn’t compromise quality when buying these products, whether on discount or when considering cheaper options.

Advertised Health Benefits

According to the FDA regulations, supplement manufacturers shouldn’t advertise their products as a preventative measure, treatment, or cure. However, some shady companies still fail to uphold this principle by claiming that their products can heal health conditions, eliminate them, and help you lose as much as 50lbs in seven days. Such claims are dishonest and misleading, which explains why we preferred open and honest manufacturers in their marketing and advertising claims.

The Top 10 Benefits of Vitamin C

People take vitamin C supplements for different reasons. Here are some of the perks of these supplements:

Boosts Immunity

One of the most popular and crucial benefits of vitamin C supplements is boosting immunity. The human immune system performs better with vitamin C, with studies showing that the supplements enhance white blood cells’ production and performance.

May Reduce Risk of Chronic Disease

Vitamin C is a powerful antioxidant, and antioxidants strengthen your body’s natural defenses, one of them being the immune system. Taking these supplements improves your immunity, which protects you from the risk of chronic diseases, among other health conditions.

May Help with High Blood Pressure

Millions of people worldwide suffer from high blood pressure today, making them susceptible to the risk of heart diseases. The latter is a leading cause of death, prompting the world to find an immediate solution. Studies show that vitamin C supplements are capable of helping your blood vessels relax, which reduces your blood pressure and eventually keeps the risk of heart disease a few steps away.

May Lower the Risk of Heart Disease

Heart disease is a leading cause of death globally. Fortunately, there is some proof that vitamin C supplements can lower the risk of the condition by lowering blood pressure, which is a common cause of the former. One study that involved about 300000 people, each taking 700mg of vitamin C daily, showed that the supplement could lower the risk of heart disease by up to 25% over ten years.

May Prevent Gout

Gout occurs because of uric acid buildup in the body. This common form of arthritis affects millions of people globally, but research shows that vitamin C supplements can help eliminate the uric acid buildup, thereby preventing the occurrence of gout.

Helps with Iron Absorption

Vitamin C supplements can also help people suffering from iron deficiency. The supplements can help boost your body’s iron absorbability levels by converting iron challenging to absorb into a more manageable form, such as plant-based iron. Eventually, your body absorbs more iron, killing your odds of suffering iron absorption.

Helps with Cognition

Other people also take vitamin C supplements to enhance their brain health and cognition. Vitamin C is famous for its excellent antioxidant properties, with studies showing that the latter can boost cognition and memory by targeting inflammation and toxins in the brain. Further research indicates that these supplements can help with degenerative brain conditions such as dementia.

May Reduce the Risk of Cancer

There is ample anecdotal proof that people who use vitamin C supplements have a lower cancer risk. However, scientific evidence is mixed.

Protect Against Eye Disease and Support Vision

While it may not be as proven as the benefits above, vitamin C supplements can protect you against eye disease and support vision, among other related perks. Other studies link the supplements to lower macular degeneration and the risk of cataracts.

Support Anti-Aging and Skin Health

People ingest vitamin C supplements by either oral means or by applying them directly to the skin to counter the aging effects. Studies show that these supplements enhance the skin’s health and support anti-aging impacts, making you look younger and vibrant. Like most antioxidants, vitamin C supplements help inflammation, which helps clear up skin issues.

Vitamin C is also vital for collagen production, one of the most abundant proteins in the body. The latter prevents the formation of wrinkles by supporting skin elasticity, thereby reducing the physical effects of aging. These supplements are excellent for anyone trying to look younger or reduce their risk of diseases.

The Recommended Dosage of Vitamin C

It is recommended for adults to take between 65mg to 90mg of vitamin C daily or roughly the amount of vitamin C in a cup of pineapple or a single large orange. The vitamin C tolerable upper limit (UL) is approximately 2000mg, even though exceeding the dosage is not harmful to the body. The National Institutes of Health recommends vitamin C dietary allowance (Recommended Dietary Allowances, RDAs) as follows:

  • 0 to 6 Months: 40mg
  • 7 to 12 Months: 50mg
  • 1 to 3 Years: 15mg
  • 4 to 8 Years: 25mg
  • 9 to 13 Years: 45mg
  • 14 to 18 Years: 75mg for boys, 65mg for girls (80mg and 115mg pregnant and lactating)
  • 19+ Years: 90mg for men, 75mg for women (85mg and 120mg for pregnant and lactating)
  • Smokers need 35mg more vitamin C per day than non-smokers.

The Best Food Sources of Vitamin C

The human body doesn’t make vitamin C by itself. To meet the vitamin C dietary demands, you should consume either vitamin C-rich foods or supplements. The National Institutes of Health identifies the following sources as the best options:

  • Red Pepper: 95mg, 106% DV per 1/2 serving
  • Orange Juice: 93mg, 103% DV per 3/4 serving
  • Orange: 70mg, 78% DV in medium-sized orange

  • Green Pepper: 60mg, or 67% DV in 1/2 cup serving
  • Broccoli: 51mg, or 57% DV in cooked broccoli; 39mg or 43% DV in 1/2 cup of raw broccoli
  • Strawberries: 49mg, or 54% DV in 1/2 cup of sliced strawberries
  • Brussels Sprouts: 48mg, or 53% DV in 1/2 cup of Brussels sprouts
  • Grapefruit: 39mg, or 43% DV in 1/2 of a medium-sized grapefruit
  • Tomato Juice: 33mg, or 37% DV in 3/4 cup of tomato juice
  • Cantaloupe: 29mg, or 32% DV in 1/2 cup of cantaloupe

  • Spinach: 9mg, or 10% DV in 1/2 cup of cooked, raw spinach
  • Green Peas: 8mg, or 9% DV in 1/2 cup of cooked or frozen peas

Studies show that the body can’t distinguish between vitamin C from food sources and supplements. However, the above food sources offer additional benefits sic as minerals and vitamins, but you can benefit by getting equivalent doses from quality supplements.

Some People Have Higher Risk of Vitamin C Deficiency than Others

Most adults do not meet their daily recommended intake of vitamin C. However, the following categories of people have a higher risk of suffering vitamin C deficiency and should be more cautious:

Smokers and Passive Smokers

Smoking increases oxidative stress, which increases your need for vitamin C. The average smoker needs 35mg more than an average person, between 50% and 100% more than the daily recommended. Passive smokers are not an exception to the increased vitamin C daily intake for smokers – second-hand smokers.

Infants Taking Evaporated or Boiled Milk

Breast milk and infant formula provide infants with adequate amounts of vitamin C. Children taking boiled cow’s milk or evaporated milk need an additional source of vitamin C.

People with Unhealthy or Imbalanced Diets

People on a poorly balanced diet or who don’t take good fruits are highly susceptible to vitamin C deficiency. Unfortunately, the latter occurs unknowingly to most people, especially those following a fad diet – poorly balanced.

Scientific Evidence for Vitamin C Supplements

People take vitamin C supplements for many reasons, from enhancing their general health and wellness to counteracting the aging effects. Most of these perks are scientifically proven.

Vitamin C supplements are proven to boost the immune system. The element is a powerful antioxidant, and antioxidants are popular for tremendously boosting immunity. Studies show that daily consumption of vitamin C supplements can immensely raise your antioxidant levels in your body by up to 30%, thereby restoring your body’s natural defenses against inflammation. A body with healthy levels of inflammation has a stronger immunity.

Researchers believe that vitamin C enhances your immunity by promoting the production of white blood cells. In this study, researchers ascertained that vitamin C supplements raise the levels of phagocytes and lymphocytes, which are two types of white blood cells that protect the body against disease-causing microorganisms.

Vitamin C supplementation also enhances and nourishes your skin, which is the body’s most robust natural defense mechanism. Research shows that vitamin C is vital for promoting the skin’s defense system, as shown in this study. Your body transports vitamin C to all parts, including the skin, through the bloodstream.

Being a powerful antioxidant, vitamin C strengthens the skin barriers while boosting the body’s ability to fight against invaders. Another study showed that vitamin C reduces the healing times of wounds, making it easier for the body to recover from physical injuries.

Vitamin C supplements may also help reduce blood pressure and promote heart health. For instance, in this study, researchers found out these supplementations help relax the blood vessels carrying blood from the heart, reducing blood pressure. A review of 29 human studies found that the supplements immensely reduce the systolic and diastolic blood pressure by 3.8 mmHg and 1.5 mmHg on average.

A separate study showed that people who take at least 700mg of vitamin C daily across ten years reduce their risk of heart disease by up to 25% compared to those who don’t take the supplementation. The study involved 293172 people. Moreover, vitamin C also helps with cholesterol, as shown in this study in which the participants recorded an LDL cholesterol drop of 7.9 mg/dL and blood triglycerides by 20.1mg/dL.

Other people also take vitamin C supplements to support their memory, cognition, and brain health. Most degenerative brain conditions are linked to oxidative stress and inflammation within the brain. This study identified a link between vitamin C deficiency and an impaired ability to think and remedy. A separate study similarly found that most people with dementia have low vitamin C levels.

Other people take vitamin C supplementation for their purportedly anti-cancer properties. There is some proof that vitamin C supplements can help fight cancer, even though the claims haven’t been proven. For instance, researchers in this review study found that vitamin C doesn’t lower or raise the chances of developing cancer.

Other people take vitamin C supplements to help improve their eye health and vision. This study, however, found no connection between the supplements and eye health even though the former had no harm to the eyes – but did not improve eye health either.

Vitamin C supplements are easily absorbed into the body, making them popular. Unlike vitamin E supplements that use a different vitamin E form from what you get from food sources, vitamin C formulas contain the same version, ascorbic acid, which is easy to absorb. Besides, the body can access the same, whether through formula or food sources.

Vitamin C supplements are generally science-backed and linked to anti-aging, improved immunity, and better health and wellness, among related effects.

Vitamin C Supplements Side Effects

Vitamin C supplements are not linked to any severe side effects when used by healthy adults as recommended. Even in excessive dosages, the element is not harmful to your body or health. However, some people may record the following side effects because of vitamin C overdoses:

  • Upset stomach
  • Indigestion
  • Nausea
  • Headaches

Notably, these side effects are rare, but if you experience them, you should reduce your vitamin C supplementation intake and stop if it becomes severe. It is also vital to talk to your doctor before taking these supplements if you have an underlying condition or ongoing medication.
