Vitamin C Product Buyer’s Guide (updated May 2024)

Information About Vitamin C

Vitamin C is an essential, water-soluble vitamin which the human body needs but is unable to produce on its own. Therefore, it must be ingested from external sources, and while food contains a certain amount of Vitamin C, it is not so easily absorbed by the body and isn’t always enough to meet individual needs and provide all the benefits. Vitamin C functions in the body as an antioxidant, meaning it fights harmful molecules called free radicals to help reduce oxidative stress and provide cellular protection. It also helps to support the immune system, and it is necessary for the production of collagen (a vital protein). In addition, it has been shown to provide many more benefits such as promoting cardiovascular and cognitive health, improving iron absorption, and fighting allergy symptoms.

Vitamin C can provide all these benefits when taken as a supplement. The most common type of Vitamin C used in supplements is ascorbic acid. The problem is that when given in large doses (which are needed to support optimal results), ascorbic acid may cause gastrointestinal distress due to its acidic nature and low absorption rate in the body. Therefore, when looking for a quality supplement, it is important that the product that you choose is formulated correctly to address these problems. 

The solutions to these issues are really quite simple. Unfortunately, most Vitamin C manufacturers don’t bother addressing them and use low quality ingredients in their formula, meaning that not only are their supplements ineffective, but they might also cause you great discomfort while using them!

Given the right formula, from a quality manufacturer that has based their product upon scientific research and clinical data, there are Vitamin C supplements out there that will do exactly what they say they will, with many people experiencing incredible results. Our research has shown that given the correct dosage and potency of 1000mg liposomal Vitamin C – you can achieve the results that you want.

Key points to consider when choosing a Vitamin C supplement

Of course, you will be dubious, so were we. Many manufacturers of health care supplements make grand promises of renewed health, only for the consumer to find out a month later that there is no real change and they are left with an empty bottle, empty purse, and empty promises. Don’t be dismayed – there are some that really do work! You just need to find a genuine product.

When choosing a Vitamin C supplement, you should look for a company with a strong reputation that sells a wide range of nutritional natural dietary health supplements manufactured in a GMP certified and FDA licensed laboratory. An effective supplement will be formulated using high-quality liposomal Vitamin C that has been proven effective in clinical trials.

Should you decide that a Vitamin C supplement is for you, and you would like to try a top-quality product, check out our reviews for a number of Vitamin C supplements that are currently available on the market. We examined numerous products for their ingredients, consumer feedback, business reputation and much more to help you discover which supplements are the real deal! You no longer need to search Google for your answers! No more guesswork – we have done all the hard work for you.

What makes a Vitamin C supplement effective?

There are several key elements which make a highly effective, top-quality Vitamin C supplement that is easily absorbed and causes zero stomach discomfort. Firstly, it is vital that you only buy liposomal Vitamin C. Since Vitamin C is a water-soluble vitamin, it is poorly absorbed by the cells in your body. Enter phospholipids – compounds that are both water-soluble and fat-soluble. The phospholipids surround the Vitamin C, forming liposomes – which have a fat-soluble outer layer – making it possible for the vitamin to be easily absorbed by the cells. 

Secondly, in order to avoid the stomach discomfort Vitamin C can cause due to its acidity, it is recommended that the supplement you choose include a buffered form of Vitamin C. Simply put, ‘buffered’ means that these vitamins include minerals that neutralize them, making them less acidic and hence gentler on the stomach. So, for example, the supplement you choose could include sodium ascorbate or calcium ascorbate, which are both buffered forms of Vitamin C.

Two more key ingredients to look for in any Vitamin C supplement are quercetin and piperine. Quercetin provides impressive antioxidant and anti-inflammatory properties, and also enhances the antiviral and antioxidant properties found in Vitamin C. Piperine is an enhancer which improves the absorption of Vitamin C even further. 

Using the correct dosage and potency of clinically-proven key ingredients will help achieve results like nothing else. Also be on the lookout for third-party certifications for purity and safety.

Our recommended choice stands above and beyond the competition, we think you will agree. The company’s excellent reputation, high-quality product, external independent monitoring and testing, coupled with an incredible money-back guarantee policy, makes this a formula that you are going to want to take a closer look at.

California Gold Nutrition Liposomal Vitamin C

Promoted as a health supplement to help boost antioxidant and immune system support, California Gold Nutrition Liposomal Vitamin C is our next product up for review. This product contains 1000mg liposomal Vitamin C and 500mg phospholipids, but is that enough to make it a successful product? 

When reviewing this product, we were pleased to see a price tag that suggests quality – not cheap, but definitely affordable. We appreciated that this product is formulated with buffered liposomal Vitamin C as it is backed by clinical studies. However, it is unclear to us if this formula will actually be effective. Without quercetin or piperine to increase absorption, it is doubtful if the efficacy of this product can compete with that of our Editor’s Choice. 

Additionally, the individual packaging intended as a convenience to preserve freshness and provide precise portions seems unnecessary and wasteful, and some consumers found the natural orange flavor of this liquid Vitamin C to be unappealing. This product contains soy, so it is not suitable for individuals with allergies. If consumers would like to try this product, they should be aware that the return policy is for 60 days but does not include a money-back guarantee. Continue reading our review to see if this product is worth your time and money.

BioAbsorb Nutraceuticals Liposomal C1000

BioAbsorb Nutraceuticals Liposomal C1000 claims to be an effective Vitamin C supplement that boosts the immune system and aids collagen production. It is vegan and GMP certified. The dose contained is 1000mg of liposomal Vitamin C which is more than found in many brands but still slightly less than the amount found in our Editor’s Choice product. 

The main issue with this product is that it doesn’t stipulate the amount of phospholipids used in its formula, which is one of the first things we look for when reviewing liposomal Vitamin C. It also doesn’t contain quercetin or piperine, which puts into question the efficacy of this product.

Another aspect we researched is the flavor of this supplement as well as the preservatives added to it. We did appreciate the fact that it doesn’t include soy as the source for phospholipids. Additionally, this product comes with a solid money-back guarantee. Continue reading our full review to see what this product has to offer.
