Pros:

Very potent

High purity

Enormous volume per package

Extremely popular

Cons:

Strong taste

Bulk Supplements lives up to its name by offering bulk quantities of various vitamins and minerals for a reasonable price. Their Vitamin C formula is no exception to this practice, offering a highly potent and extremely pure package that is overwhelmingly loved by customers.

Read more

Potency

The pure ascorbic acid used as the key ingredient in a Vitamin C supplement is at its most potent in this specific product’s powder. A perfect 1:1 ratio of Vitamin C to formula is tough to beat, and the benefit of the powder format makes it easy to measure out specific dosages.

Purity

The only ingredient you are going to find in this powder is ascorbic acid. No effort has been made to purify it, which does limit its total potency. However, this lack of additional chemicals such as sodium helps to keep the formula pure.

Taste

It’s true that the high concentration of acidic substances in this powder will have a strong sour taste. This taste will disgust the majority of individuals who take it, but it can be mitigated to a degree if you mix it with a strong-tasting liquid such as juice.

Cost and Value

This is the most expensive supplement on this list, which is bound to turn off many individuals who are just looking for a bit of extra Vitamin C to help them get through flu season. However, if you’re looking for enough Vitamin C to last you for the next few years, this is the package to buy.

Pros:

Extremely high potency

High volume per package

Pleasant taste

No acidity

Cons:

Mild salt content

As opposed to most low-cost Vitamin C supplements that simply use pure ascorbic acid, Nutribiotic’s supplement goes one step further for the benefit of the customer. The vitamins that are synthesized from this common method are filtered, resulting in a purer and tastier powder supplement.

Read more

Potency

With one-quarter of a teaspoon containing just over 1,100 mg of sodium ascorbate, this is an extremely potent Vitamin C formula. In fact, such a high potency can be negative, as it is much easier to take a considerably greater dosage than you may originally intend to.

Purity

Nutribiotic’s formula is made of Sodium Ascorbate, a substance derived from a combination of salt and ascorbic acid. Using the salt as a filtration method, this formula has extremely pure Vitamin C crystals packed in each serving. However, some residual salt is left in the formula to the detriment of its overall purity.

Taste

Since the ascorbic acid used to synthesize Vitamin C in this supplement was filtered, no bitter or tart taste is present when consuming this formula. Instead, there is a mild salty taste, which is due to the sodium filtration method used to get pure crystals. According to customers, this taste is considerably better than other supplements on the market.

Cost and Value

It’s true that this pack of supplements is on the more expensive side of the spectrum for Vitamin C prices. However, one year’s worth of servings are contained in just one bottle, thanks to the extremely high potency of this formula. Because of that, this ends up being one of the most inexpensive supplements once you account for volume.

Pros:

Unparalleled purity

No taste

Terrific price

Highly soluble powder-based form

Cons:

Not very popular

What’s most notable about this Vitamin C supplement from Twinlab is the source of its key ingredient. Since it comes in a pure crystallized form, the purity offered by this product is matched only by its high potency. It’s truly a shame that it isn’t as popular as many other brands, since it provides an excellent amount of Vitamin C in a fantastic package.

Read more

Potency

Twinlab’s supplement contains 1,000 mg of Vitamin C, as the name implies. The source of this nutrient is difficult to discern due to a lack of information offered on the back of the bottle or on the publisher’s website. All that is stated is that the capsules contain crystallized concentrations of the substance.

Purity

Regardless of where the Vitamin C is derived from in this supplement, the fact remains that it is highly pure. Some mild bonding agents are inactive ingredients used for the construction of the capsules that contain this supplement, but the only other ingredient present is pure crystallized Vitamin C.

Taste

Since no acid or citrus was used in the making of this formula, there isn’t any strong bitter or sour taste that accompanies it. However, it is still a good idea to take this pill without breaking the capsule in order to avoid choking. For the most part, there isn’t any significant taste to speak of.

Cost and Value

While a few other capsule-based supplements will offer a similar size and potency capsules for a better price, Twinlab’s Vitamin C supplement is still one of the most affordable ones available for purchase. It can be a greater value according to volume if you purchase a powder-based supplement, but this is the perfect compromise between a low initial price and a high volume.

Pros:

High potency

Additional natural ingredients

Very affordable

Vegetable coating for the capsules

Cons:

Slightly diminished potency

NOW’s Vitamin C supplement advertises the addition of natural ingredients to their potent formula. While it’s true that the meager amount of rose hip extract helps to bolster these pills’ Vitamin C content, the addition is too small to really call this product natural or organic. Regardless, it provides a high potency and purity, all for a very reasonable cost.

Read more

Potency

In addition to having the standard 1,000 mg of Vitamin C derived from ascorbic acid, this supplement also contains a small amount of rose hips powder. This is another common source of Vitamin C that is natural, but the amount contained is insignificant when compared to the acid-derived portions of the formula.

Purity

Other than the vegetable-based coating used for manufacturing the capsules, this supplement only carries ingredients that provide the body with Vitamin C. The purity of NOW’s formula is slightly weakened due to the addition of rosehips since it offers a less pure source of the nutrient.

Taste

The addition of rosehips to the formula gives these capsules a sour or tart taste. This difference is subtle, however, and easily overpowered by the bitter-tasting ascorbic acid. For the most part, you should be able to avoid tasting these supplements at all if you swallow them whole with the aid of some liquid.

Cost and Value

Despite containing a few extra ingredients, the affordability of these Vitamin C supplements are easily comparable to many simpler products on the market. In many cases, these are actually more affordable than most tablets or capsule-based formulas, since one bottle can last for several months if taken at the minimum dose.

Pros:

Adequate potency

Tasteless, making them easy to consume

Cons:

Less popular

There isn’t anything in particular that sets this Vitamin C supplement apart from any others available to purchase. However, Doctor’s Best offers a very high-quality formula for a reasonable price, making it ideal for those simply looking for a no-frills supplement.

Read more

Potency

1000 mg of ascorbic acid is used to supply the Vitamin C in this supplement. Some individuals may be turned off by the synthetic nature of this chemical, but the fact is that this is the purest and easiest method of supplying great deals of this nutrient to your body.

Purity

The only other ingredient present in the formula for this supplement is cellulose in order to form the outside of each capsule. This means that you will only be ingesting Vitamin C from an extremely pure, albeit synthetic, source. The only way this supplement could be purer is if it came in a powder.

Taste

Fortunately, the cellulose lining used to make the capsules for this supplement do not have any particular taste to them. This means that you can take these pills with water and experience no negative taste whatsoever. There isn’t even an aftertaste, which is something most Vitamin C powders can’t say.

Cost and Value

Thanks to its no-frills approach to supplying the body with Vitamin C, there isn’t a great deal of cost to the production of these capsules. This allows Doctor’s Best to sell them at a very competitive price, providing an extra benefit to the customer. One package costs half as much as many competing brands and offers nearly double the number of servings.

Pros:

Terrific value

Variable potency

Decent taste

No side effects

Cons:

Lackluster purity

With a small addition of Calcium to the formula, American Health’s brand of Vitamin C supplements offer some qualities similar to a multivitamin. This is an excellent value for a high volume of easily digested nutritional supplements.

Read more

Potency

While each capsule only contains 500 mg of Vitamin C, a comparable dose to most other formulas available for purchase can be achieved by simply doubling the dose. In fact, this seeming lack of potency can make it easier to fine-tune your dosing to fit specific dietary needs.

Purity

Instead of using the most common and most pure form of Vitamin C, ascorbic acid, American Health Ester-C uses a slight variation on this synthetic formula called Calcium Ascorbate. It’s very similar to ascorbic acid but also contains a small amount of calcium, which provides further nutritional value but does detract from the overall purity of this supplement.

Taste

The taste for this supplement isn’t as noticeable as most others since it comes in capsules instead of powders. However, people who have taken these capsules as intended say that the taste is decent, especially when compared to other formulas on the market. Grinding it up for whatever reason will result in a bitter taste.

Cost and Value

At roughly 7 cents a capsule, these are some of the most affordable supplements on the market, second only to bulk ascorbic acid powder bags. For the cost of one month’s supply for a competing brand, you can get enough American Health Ester-C to last you roughly 4 months.

Cons:

Disappointing purity

With an interesting method of delivery, Lypo-Spheric’s Vitamin C powder supplement sets itself apart from other products on the market. However, the compromises made on purity and price may end up turning some customers away.

Read more

Potency

In addition to containing 1,000 mg of Vitamin C, this powder supplement utilizes liposomal encapsulation and delivery technology to increase its potency. What those big words mean is that the manufacturers of this supplement used liposomes, or tiny spherical containers, to bypass the membrane layer and directly provide your bloodstream with Vitamin C.

Purity

Although the majority of this powder formula is made from ascorbic acid, an incredibly pure synthetic source of Vitamin C, there are a few other ingredients added that dilute the purity of this product. One additional element that is prominently featured is soy lecithin, the source of the lipids used to facilitate the liposomal delivery technology.

Taste

Some customers have noticed no taste when taking this formula, while others have noticed a strong unappealing taste. In any case, you shouldn’t expect this powder to taste good. One recommendation to dilute this strong taste is to mix this formula in with a tastier liquid such as orange juice.

Cost and Value

This container of Vitamin C comes at a higher cost than many others of its kind, and it doesn’t balance out when looking at the volume per container either. However, the increased price is justified due to the liposomal delivery technology that was implemented in this formula. This ensures that all of the Vitamin C becomes absorbed in your body, as opposed to other highly-concentrated supplements that your body will usually filter out.

Pros:

Easily mixable powder form

Cons:

Bitter taste

It doesn’t get any simpler than this. Bronson Nutrition’s line of Vitamin C powder is the easiest way to get your daily dose of this essential nutrient. Enough Ascorbic acid is present in each package to last you for years if taken sparingly.

Read more

Potency

Containing 1,000 mg of Vitamin C in roughly a quarter of a teaspoon, Bronson’s Vitamin C powder supplement is extremely potent. This ensures that each package contains a high volume and offers a good value, but it also increases the risk of developing adverse effects from ingesting too much.

Purity

This supplement is made solely of Ascorbic acid, a chemical that is used to synthesize Vitamin C. Adding the fact that it comes in powder form and thus doesn’t require gelatin or rice flour to contain it, this is one of the purest sources of Vitamin C you can buy.

Taste

The unfortunate downside of this supplement being incredibly pure is that nothing has been added to make the taste more appealing. Expect a very bitter taste when mixing this solution with water. Because of this, you may want to mix it with a tastier liquid or add some sugar.

Cost and Value

The base price for this powder supplement is pretty high when compared to many others listed here, but this evens out once you account for the volume factor. If you’re looking for a supply of Vitamin C that will last you for months, this is the absolute best value for your money.

Pros:

Easy dosing

Tolerable taste

Fairly priced

Cons:

Diminished potency

As its name may imply, the major selling point of this Vitamin C powder-based supplement is its all-natural ingredients. While many other supplements use synthetically-derived sources of Vitamin C, the components used in this formula are derived from fruit. While this sounds appealing to some customers, others may be surprised at the lessened potency that comes with this manufacturing decision.

Read more

Potency

This Vitamin C powder doesn’t have the same potency per serving as some other powders. This is because it derives its key ingredient from natural fruit-based sources instead of Ascorbic acid, which is the most common source. Despite this diminished potency, more Vitamin C can be added easily and safely by doubling the dosage.

Purity

Some individuals may see the fact that the Vitamin C in this supplement is derived from multiple sources as a lack of purity. However, the fact that Nature’s Way uses goji and kiwi fruit extract instead of the standard Ascorbic acid, this lack of purity is made up for with the quality of its ingredients.

Taste

Despite the composition of this supplement being derived mostly from sweet fruits, the taste of this Vitamin C powder more closely resembles chili powder, according to one online reviewer. It’s not the most unpleasant-tasting powder on the market, but the taste can take you by surprise if you aren’t careful.

Cost and Value

The cost for one package of this powder is low, but this initial affordability doesn’t stack up when accounting for volume. One package contains enough servings for roughly a month, but when you consider the diminished potency, this really translates to two weeks of double servings. However, if you’re interested in a more natural supplement and don’t need 1000 mg with each serving, this is a fine price.

Pros:

Excellent skin care properties

High effectiveness

Substantial popularity

Fairly priced

Cons:

No nutritional value

A far cry from the other supplements on this list, the Serumologie Vitamin C Serum utilizes this nutrient for completely different health concerns. It’s true that this supplement doesn’t supply the same nutritional value as a capsule or powder, but the positive effects it can have on your skin make it worth considering for the treatment of these symptoms.

Read more

Potency

It’s difficult to determine exactly how potent this Vitamin C product is, since it is administered in a very different way than all other products on this list. As a topical serum, five to seven drops are rubbed into the skin, purportedly helping to promote healthier and clearer skin. It won’t fulfill the nutritional requirements that other Vitamin C supplements will, but it does provide some nutritional value.

Purity

Being designed primarily to aid in repairing damaged skin, this serum is mixed with several other chemicals intended for this purpose. Because of this, the purity of this product is low, but it still manages to accomplish the task it sets out to with the aid of these additions. In addition, this serum is vegan, despite these extra chemicals.

Taste

Since this product isn’t taken orally, taste shouldn’t be an issue. In order to achieve the highest effectiveness, you should avoid putting any of this substance in your mouth and instead put in on your skin. However, some customers have noticed a strange metallic taste in their mouths as a side effect, so be wary of this possibility.

Cost and Value

When compared to other skin care products and topical creams, this Vitamin C supplement is quite affordable. However, when compared to the multitudes of oral Vitamin C supplements that aren’t intended for skin care, these cost a great deal more than most. However, the specific features offered by this package make them worth this higher price.

Criteria Used for Evaluation

Potency

When picking out any supplement, the first thing to look out for is how much of the key ingredient is present in each supplement. The majority of these products have around 1,000 milligrams of Vitamin C in each serving, but serving sizes can vary. This determining factor evaluates how potent one serving is in order to find the supplements that require the least volume in order to consume the required nutrients for proper bodily health.

Product Purity

Some supplements are marketed as multivitamins, containing multiple different nutrients in one serving. These can be helpful for some individuals who wish to further supplement their diet while taking fewer pills, but that is not the focus of this buying guide. In the case of Vitamin C supplements, any additional ingredients that aren’t sources of Vitamin C are considered superfluous and take away from the product’s purity. In order to judge the purity of each project, the amount of active ingredients is weighed against any extra chemicals.

Effectiveness

Whether it’s taken in a powder or a pill, supplements can have a particular taste and effectiveness to them. They are often intended to be taken with water, which can serve to either enhance or dull the overall taste. In any case, the taste of a supplement can often be disgusting to an individual if it is too strong. This category determines the taste of each product based on the form it is administered as well as the general consensus of customers who have tried it.

Brand

It can be scary taking a new medicine or supplement. It is always a good idea to consult a doctor or medical professional before taking any new medication in order to make sure that it is safe for consumption. However, another good way of determining the effectiveness of a supplement is to seek out the opinions of those who have already tried it. This section evaluates how many customers have tried each product, whether their experience with it was positive or negative, and what particular aspects of the product stood out to them.

Value

When taking into account how affordable each product on this list is, more than just the base price was considered. One product could cost less than another but end up having a less potent formula and fewer total servings. This is why the total volume and number of servings were evaluated while determining this important factor.

Frequently Asked Questions

q: Can I take these supplements instead of food?
a:

You cannot eat nutritional supplements and multivitamins in place of regular food and maintain proper bodily health. The body requires a certain amount of calories to function properly which cannot be provided by simply taking vitamin supplements. In addition, healthy foods offer high concentrations of other important nutrients, such as fiber and protein, that are very difficult to replace with the aid of supplements.

q: Can I overdose on Vitamin C?
a:

It is physically impossible for a human to take a lethal dose of Vitamin C due to the sheer amount they would have to take in order to reach it. However, negative effects can occur in the body if you take too much of it. Some minor overdose symptoms include nausea and digestive issues such as diarrhea, and more severe symptoms include the development of kidney stones.

q: How much Vitamin C should I take every day?
a:

The daily recommended dose of Vitamin C as prescribed by nutritionists is around 75 milligrams. However, it is safe to take much higher amounts than this daily, and many individuals have noticed positive health benefits to their skin and immune system when taken in higher dosages. 1,000 milligrams is a common serving size, but you can take up to 2,000 a day before experiencing negative effects.

q: Will Vitamin C cure a cold?
a:

Since Vitamin C has properties which help to boost the body’s immune system, it can protect you from the onset of sicknesses such as the common cold or the flu. In some cases, individuals have been able to reduce the amount of time a cold has affected them by taking high doses of Vitamin C. However, there is no scientific evidence at this time that taking Vitamin C will cure a common cold.

q: Will Vitamin C keep me awake?
a:

Vitamin C is not a stimulant and will not keep you awake, even if you take it right before going to sleep. On the other hand, correcting a Vitamin C deficiency by taking it regularly can help you achieve longer periods of restful sleep at night.
