Sufficient-C For Better Vitamin C

by Carly Neubert, BA, NC on April 22, 2020

Vitamin C deficiency can be a difficult thing to avoid. Getting enough vitamin C through sources like your food, especially when you're sick or recovering from an illness, is almost impossible. This is why a drink like Sufficient-C is so important. Sufficient-C is a highly concentrated vitamin drink specifically designed for making vitamin C maintenance as easy and as tasty as possible.

Scurvy & The Body's Need for Vitamin C

During the age of sail, when half the world was yet undiscovered, agricultural production grew to a point that sailors were able to store food for long periods of time and subsequently take it on lengthy voyages across the sea. Oftentimes, however, fresh fruit and vegetables were not readily available, especially on voyages that took months, or even years.

Think about a bunch of bananas sitting on your kitchen counter. After about a week’s time, they’re nearly inedible (unless you like brown and squishy fruit). It would be almost impossible to store fresh food for even 1 month, especially at a more primitive time in our history. As a result of their nutritional deficiencies, sailors suffered from and often lost their lives to a deadly disease known as scurvy.

It wasn’t until midway through the 18th century that scurvy became recognized in the British medical community as being caused by a dietary deficiency, and not caused by consuming eels or something of the like. Scottish physician James Lynd was an essential part in discovering the restorative and healing effects of citrus fruits for naval soldiers.

It was by Lynd's recommendation that lime juice was taken and stored on all voyages, and eventually, this led to the eradication of scurvy from within the entire British fleet. Much later, Albert Szent-Gyorgyi, a Hungarian researcher, would be awarded a Nobel Prize in Medicine for his discoveries about vitamin C, ascorbic acid, and their attendant effects on the body.

In modern times, we’ve learned that scurvy is only an extreme byproduct of vitamin C deficiency. The vitamin plays a vital role in your bodily function, and we need it more than we think.  

What is Vitamin C?

As defined by the National Institutes of Health, “vitamin C is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C...so it is an essential dietary component.” Vitamin C is also well-known as L-ascorbic acid. Because of its high antioxidant properties, vitamin C is absolutely essential for many functions in your body.

Collagen production requires vitamin C, as do certain neurotransmitters and connective tissues (think: wound healing). Scurvy is completely characterized by extreme weaknesses in the connective tissues in the body, so this makes sense.

As research is beginning to prove, vitamin C may help delay or prevent totally the onset of certain cancers, heart disease, or other diseases. This is because the antioxidant content in vitamin C helps to eliminate free radicals in the body, thus reducing oxidative stress. Most importantly, however, vitamin C is known for its immune ability, whether that be fortifying your immune system or nourishing it back to functional health.

How Much Vitamin C Do You Need?

Did you know that you can get your total RDA (Recommended Daily Allowance) of vitamin C by eating just one large orange or sweet red bell pepper? Doesn't that sound easy and super convenient? See, the RDA for vitamin C is only 70 milligrams. But those 70 milligrams will only keep you from dying of scurvy. If you want to thrive and live at optimal energy levels, then you probably need more vitamin C than just 70 milligrams!

The Vitamin C Foundation recommends 3000 mg per day for maintenance of healthy adults and the Linus Pauling Institute advocates for 6000-18,000 milligrams per day. For illnesses and injury, both groups suggest 20,000 milligrams (20 grams) or more per day.

Plus, history and science have proven that the higher, effective doses of vitamin C are what the immune system needs to lower vulnerability to viruses and bacteria. Vitamin C in the higher doses acts as a natural antibiotic, natural antiviral, natural anti-inflammatory, and even natural antihistamine, but the key for these therapeutic effects requires that a sufficient amount be consumed throughout the day. It is pretty difficult and may even be impossible to get those doses from food sources, and this is where the Sufficient-C supplement comes in.

History of Sufficient-C

Sufficient-C is a highly concentrated vitamin drink formulated for optimal immune support. Its substantial vitamin C content makes it an easy way to actually fuel your body with the high amount of vitamin C it needs to function. Vitamin C is naturally water soluble, and Sufficient-C was formulated with that in mind. Rather than downing dozens of pills, Sufficient-C simplified the process by creating a 100% water-soluble drink mix that makes it easy and refreshing to obtain the year-round immune support you need and the sweet, satisfying flavor you crave.

Sufficient-C’s founder and CEO has shared her story and related how its personal nature drove her to create such a wonderful and effective product. She tells,

“When my mother was diagnosed with lung cancer, she struggled with both the physical effects of her disease as well as her chosen conventional cancer treatment. I was struggling with both tremendous concern for her health and that same treatment. Knowing that the body's need for vitamin C is increased when stressed with illness, it was clear to me that my mother was not getting nearly enough.

As a very persistent daughter, I think it is fair to say that she was getting tired of my mantra of immune supportive recommendations that always included high-dosed-vitamin C-supplementation. As a result, my mother grew tired of what she felt was a tirade of suggestions. She even professed that she was unwilling to add yet a ‘single other vitamin supplement’ to her daily routine.”

This became the turning point. Rather than going down the road of creating a traditional nutritional supplement, the creator of Sufficient-C strove to create a great tasting, refreshing vitamin C drink with a highly concentrated dose of the antioxidant itself that would compel “frequent hydration and vitamin C fortification.” She says again,

“Sufficient-C offers one-of-a-kind, flavor with function in the form of a hydrating, satisfying immune supportive drink mix. It is a refreshing, seamless solution for those that are tired of swallowing many pills and capsules and simply need and want more vitamin C, but we didn’t stop there. Sufficient-C also contains generous doses of L-lysine, bromelain and a 94% pure, patented, caffeine-free green tea extract too for outstanding immune and inflammation support like never before!”

Sufficient-C's Clean Ingredients

Because Sufficient-C was created in an effort to complement and aid cancer treatment, it’s a remarkably clean product. Sufficient-C is certified gluten-free, sugar-free, caffeine-free, kosher, 100% vegan, and non-GMO. If you taste Sufficient-C, you may not believe it’s sugar-free. Many nutritional, vitamin, or supplement drinks use large amounts of sugar to disguise the taste of the vitamins, but Sufficient-C is just about the opposite.

The product’s creator knew from a holistic approach that in many cases sugar can aggravate the effects of cancer, and so with her mother in mind, she used an all-natural alternative: stevia.

Stevia is a calorie-free sugar substitute 100% derived from the leaves of the stevia plant. In addition to it containing zero calories, in the same concentration as sugar, stevia is nearly 200 times sweeter. What’s not to like? Back to Sufficient-C and the effort to create an all-natural vitamin C supplement product, stevia fits right into the mix (literally).

Interestingly enough, sugar actually impedes the absorption of vitamin C in the body, thus stevia was the only sweetener that would work. And work it does. Due to stevia and the other natural, plant-based fruit extracts in the drink mix, Sufficient-C has a great, satisfyingly-sweet taste without all the bad stuff.

To top it off, Sufficient-C uses a premium, non-GMO ascorbic acid in its blend.

Endorsed by Riordan Clinic

To add to this products impressive list of pro’s, Sufficient-C is also endorsed by the Riordan Clinic. The Riordan Clinic is a nonprofit nutrition-based health facility with a goal to discover the root cause of diseases, rather than focusing on managing symptoms alone. They say,

“simply put, we aren’t just looking to label what is wrong with you – we want to find out why the disease occurred in the first place and then to address those causes. We have over four decades of experience in successfully treating a wide variety of sustained illnesses including Cancer, Lyme Disease, Heart Disease, Chronic Fatigue Syndrome, Fibromyalgia, Diabetes, Autoimmune Disorders, Gut Issues, Food Sensitivities, and more.”

You will see this endorsement proudly displayed on their product label. Erin Manning, MBA, Director of Marketing at the Riordan Clinic says,

“In the three years that the Riordan Clinic has carried Sufficient-C in our Nutrient Store, we continue to be surprised with just how popular it is with our patients. Being well known for our work with Vitamin C we have a whole lineup of Vitamin C options. Sufficient C has quickly risen to be one of our top selling products - not just for Vitamin C but in general! We have samples at each of our water stations and get such positive feedback on the flavor as well as efficacy. We are proud of the partnership between the Riordan Clinic and Sufficient-C. We are proud to partner with Caralyn and the Sufficient-C brand for a great product, a trustworthy business relationship, and unprecedented customer service.”

Sufficient-C get’s such positive feedback from everyone who uses it because it really is as effective as it claims to be.

Sufficient-C and Viral Immune Health

Sufficient C isn’t just powdered vitamin C. It is a complete wellness formula that contains immune-boosting L-lysine, Bromelain, and EGCG (green tea extract) and, of course, vitamin C. You may not think about your immune system until the dreaded cold and flu season arrives. Then, you are counting on your immune system to protect you against viruses of all strains.

Vitamin C

Vitamin C has over 64,000 published medical studies and has been tested against many viruses including SARS coronavirus and herpes simplex. An analysis of 148 different studies concluded “vitamin C may alleviate or prevent infections caused by bacteria, viruses, and protozoa.” 

Vitamin C works on several levels to help you fight a virus. 

  1. It stimulates the activity of some of your immune cells called Natural Killer cells. These are the soldier cells that kill cells affected by viruses.
  2. Vitamin C slows the replication of a virus.
  3. It protects lung tissue by slowing inflammatory cytokine release.
  4. Vitamin C helps grow/mature T-Lymphocytes which protect your body from infections (viruses, parasites, bacteria).
  5. It helps with the absorption of iron which can be depleted by viral infections. 
  6. Vitamin C acts as an antioxidant for damaged cells.

L-lysine is an amino acid. You probably don’t think of amino acids for bolstering your immune system, but that is one of its most important responsibilities in your body. Lysine molecules are necessary for you to produce antibodies. These protein molecules attach to enemies (think virus, bacteria, or other pathogen), and label them as invaders. Once an invader is tagged with an antibody, your other immune cells know which cells are safe, and which are foreign. Without lysine, your body can’t make antibodies.

EGCG (Epigallocatechin Gallate)

Like vitamin C, EGCG (epigallocatechin gallate) is also an antioxidant. EGCG is an extract taken from green tea. It is the main catechin (plant nutrient) that gives green tea its’ long-standing reputation as being a healthier option to coffee or energy drinks. In 20082013, and 2018 green tea extract EGCG was tested against the prevalent influenza virus strains. All experiments showed EGCG is capable of slowing the multiplication of the virus.


Bromelain is a well-known anti-inflammatory enzyme used for digestion and arthritic aches. A lesser-known function is bromelain’s ability to stimulate immune cell activity. Bromelain acts as a warning bell to alert immune cells to invading viruses or other pathogens. After the immune cells take over, excess bromelain is used to reduce inflammation caused by invading pathogens. 

Sufficient C is a full spectrum high-powered immune system support formula. It is fortified with top anti-viral nutrients to support your immune cells.


Though we no longer live in the days of transcontinental voyages and scurvy, it’s more important than ever to get more vitamin C in our bodies than we have currently. It’s one of the foundational vitamins because it helps make everything in your body work, and scurvy is an awesome example of what happens to your body when you go without it.

With Sufficient-C, you can enjoy the ease of healthy hydration and knowing you’re getting the vitamin C you need, rather than experience the daunting task of swallowing many pills and capsules. Flavor with function doesn't get sweeter than this!

Sufficient-C offers a refreshing combination of real plant-based flavors with a premium blend of 4,000 mg. of non-GMO vitamin C, L-lysine, Bromelain and a 94% pure green tea extract in a satisfying, thirst-quenching drink mix. Nothing about Sufficient-C is hard to swallow. Try it today!
