Taking Vitamin C is a Skill

by

“Take enough C to be symptom free, whatever the amount might be.” — Dr. Andew Saul

One of the most interesting things I learned from Dr. Andrew Saul is that taking vitamin C is a skill.

It’s not about swallowing a daily dose and moving on.

It’s about understanding your body’s unique needs and how they change daily.

At first, I thought I had it figured out. My dad rarely got sick, and his secret seemed simple—2 grams of Vitamin C a day, which felt groundbreaking at the time. Then I learned that professional athletes, like the Seattle Seahawks, used 10-gram IV doses to recover faster and perform better.

That blew my mind.

But when I came across the science of mega-dosing—using 30, 50, even 100 grams of Vitamin C to fight illness and improve recovery—everything changed. It reshaped my understanding of health and taught me that Vitamin C is more than a supplement.

It’s a tool, and using it effectively requires learning and practice.

Key Takeaways

  • Dynamic Demand vs. Static Dosing: Your body’s need for Vitamin C isn’t fixed; it fluctuates based on stress, toxins, and internal “fires.” Mastering this skill allows you to match your intake to your real-time physiological requirements.

  • Precision Over IVs: While IVs provide high doses, they are often a “static” snapshot. Learning Bowel Tolerance gives you a personalized, daily feedback loop that even an expensive clinic can’t replicate.

  • The S-Curve of Absorption: Vitamin C isn’t absorbed linearly. Higher doses actually reduce bioavailability, making Pulse Dosing the superior strategy for cellular saturation.

  • Steady-State is the Goal: Because Vitamin C has a short half-life, the “skill” is maintaining a constant level in your plasma rather than one large morning spike.

  • The Osmotic Connection: High-dose Vitamin C requires proper hydration. Using the Water Cures Protocol ensures your “inner ocean” can transport these electrons effectively.

Overview Summary

Many people treat Vitamin C as a “check-the-box” daily chore.

This “standard dose” approach fails because it ignores the Dehydration of the Immune System.

Your body’s demand for Vitamin C is dynamic.  It fluctuates based on stress, toxins, and internal “fires.”

To master Vitamin C, you must move from supplementing to practicing.

While many turn to expensive IV treatments for a “boost,” those are often static solutions that don’t account for your shifting daily needs.

By leveraging the Bowel Tolerance Method and the science of the S-Curve, you can find your personal saturation point in real-time.

This article breaks down how to use Pulse Dosing and Liposomal delivery to transform Vitamin C from a simple nutrient into a high-performance tool for recovery, structural integrity (collagen), and total-body antioxidant defense.

A Note on Performance Safety

Taking Vitamin C in high doses is a potent strategy for health, but it’s a protocol that requires personal responsibility.

While Vitamin C is remarkably safe, even at mega-doses, everyone’s biological baseline is different.

If you have a history of kidney stones, G6PD deficiency, or are taking prescription medications, check with a health professional first.

The goal is to find your optimal “saturation point” safely and effectively.

Introduction: Why Vitamin C Changed Everything for Me

Vitamin C completely transformed how I think about health and healing.

I used to believe there was a standard dose—something you could just check off like a daily chore.

But over time, I realized that this approach was far too simplistic.

Your body’s needs are dynamic, and learning to adapt your Vitamin C intake to match those needs is an essential skill.

From my dad’s modest 2 grams a day to the Seahawks’ IV doses, and finally to the cutting-edge research on mega-dosing, my journey with Vitamin C has been one of constant discovery.

It’s taught me to see health not as a fixed routine but as a practice that requires awareness, experimentation, and adaptability.

Start by Learning About Vitamin C

There is an incredible wealth of knowledge on Vitamin C, but I found these two resources to be a great starting point:

  1. What has Vitamin C Already Been Proven to Do: Explore the extensive benefits of Vitamin C in boosting immunity, combating oxidative stress, detoxifying the body, and accelerating healing, as backed by decades of research.
  2. Vitamin C FAQ: A concise guide answering common questions about dosing, forms, and therapeutic uses of Vitamin C, including how to apply the bowel tolerance method to find your optimal dose.

These resources provide actionable insights to help you understand how Vitamin C can be used effectively for health and healing.

Whether you’re curious about its everyday benefits or therapeutic potential, this is the perfect foundation to get started.

Orthomolecular Medicine

Orthomolecular medicine, a concept pioneered by Nobel laureate Linus Pauling, emphasizes the use of optimal doses of natural substances—like vitamins and minerals—to support the body’s ability to heal itself.

One of the most well-known nutrients in this field is Vitamin C, often used in high doses to boost immunity, combat disease, and restore balance in the body.

In fact, much of what I’ve learned about Vitamin C aligns with the principles of orthomolecular medicine.

Whether it’s using mega-doses to fight illness or adjusting intake based on daily needs, this approach highlights how powerful and versatile Vitamin C can be.

It’s not just about taking a supplement—it’s about understanding how your body works and giving it exactly what it needs to thrive.

By exploring orthomolecular medicine, I’ve come to see Vitamin C not just as a nutrient but as a tool for achieving optimal health.

That’s why I’ve dedicated this article to unpacking its potential and teaching others how to harness it effectively.

Why is Taking Vitamin C a Skill?

Taking Vitamin C is a Skill because it’s not just about popping a pill—it’s about understanding how to use it effectively for your health.

I had to dive deep into research, experiment with different kinds and brands, and practice increasing my tolerance to mega-dosing.

For example, I learned that at higher doses—beyond 30+ grams a day—Vitamin C can reach antimicrobial levels, providing powerful support for fighting infections and boosting immunity.

It’s not something you can jump into immediately.  You need to learn things like bowel intolerance.

Over time, I’ve developed the skill of fine-tuning my intake to maximize its benefits, whether for daily wellness or addressing specific health needs.

The Science of the “S-Curve”: Why Vitamin C is a Skill

Unlike many nutrients, Vitamin C (ascorbic acid) has a unique tightly controlled absorption limit. Your body doesn’t just absorb more because you swallow more. To master the dose, you have to understand the S-Curve of Saturation.

1. The Absorption Ceiling (Bioavailability)

Your gut uses specific transporters (SVCT1) to pull Vitamin C into the bloodstream. These transporters get saturated quickly.

  • Small Doses (200mg): Nearly 100% absorption.

  • Moderate Doses (500mg): Roughly 70–80% absorption.

  • Large Doses (1,250mg+): Absorption drops to less than 50%. Any “excess” Vitamin C that isn’t absorbed stays in the gut, where it pulls in water—this is what causes the “bowel tolerance” limit.

2. The Half-Life Challenge

Vitamin C is water-soluble and has a short half-life in the blood (roughly 30 minutes to a few hours). If you take 2,000mg at 8:00 AM, your levels will spike and then plummet by lunch.

  • The High-Performance Fix: “Pulse Dosing.” Taking smaller amounts (250–500mg) several times throughout the day maintains a steady-state concentration in your plasma, ensuring your immune cells always have a full tank.

3. The Collagen & Electron Connection

Vitamin C isn’t just an “immune booster”; it is a premier electron donor.

  • Collagen Synthesis: It acts as the essential co-factor for the enzymes (prolyl hydroxylase) that knit collagen fibers together. Without it, your “structural glue” fails.

  • Antioxidant Recycling: It “recharges” Vitamin E and other antioxidants after they’ve been used up, making your entire defense system more efficient.

Your Vitamin C Needs Change Every Day

The idea that “Your Vitamin C Needs Change Every Day” reflects the dynamic nature of your body’s requirements for nutrients.

This idea completely transformed how I approach taking Vitamin C.

I used to believe there was a standard recommendation—something simple and fixed I could follow, like “take X milligrams a day and you’re good.” But I quickly learned that Vitamin C isn’t one-size-fits-all, and figuring out what my body actually needs each day became a skill I had to develop.

Your body’s demand for Vitamin C fluctuates constantly. Stress, illness, activity levels, and even your diet can dramatically change how much Vitamin C you need to stay healthy. Realizing this was a game-changer for me. It wasn’t about taking a vitamin.  It was about learning to listen to my body and adjust my intake dynamically.

Why This Shift Matters

  • It shattered the idea that a single daily recommendation works for everyone, every day.
  • It taught me to see nutrition as flexible and personal, not rigid.
  • Most importantly, it gave me the tools to take control of my health, knowing that I could adapt to whatever life throws at me.

Taking Vitamin C became more than a routine—it became an essential skill for supporting my well-being. It’s not just about the vitamin itself; it’s about learning how to use it effectively, based on what your body is telling you in the moment.

Vitamin C Dosing

Vitamin C dosing is not a “one-size-fits-all” approach. Your needs can vary dramatically depending on your health, stress levels, and whether you’re dealing with illness. Understanding how to adjust your intake based on your body’s signals is crucial for maximizing its benefits.

Here’s a quick guide to help you navigate Vitamin C dosing effectively:

  • Daily Maintenance: 2,000–10,000 mg/day for healthy individuals, adjusted based on needs.
  • Illness Treatment: Doses of 25,000–150,000 mg/day may be needed for serious conditions, administered in divided doses or via IV.
  • Supportive Practices: Combine with a healthy diet, hydration, and other supplements (e.g., magnesium) for optimal results.

From the Vitamin C FAQ:

“How much vitamin C should I take?
Your optimal dose of vitamin C depends on one thing: you. Are you healthy? Stressed? Sick? In sickness it was observed by Robert F. Cathcart, III, MD, that, “The amount of oral ascorbic acid (vitamin C) tolerated by a patient without producing diarrhea (loose bowels) increases somewhat proportionately to the stress or toxicity of his disease” and “[s]tressful conditions of any kind greatly increase utilization of vitamin C.”

In other words, the sicker or more stressed you are, the more vitamin C you will “hold” before getting to saturation (bowel tolerance). Bowel tolerance is indicated by gas, a rumbling stomach, or slightly loose stool. If you take way too much C, very loose stool will result, but this goes away once dosages are reduced.

When bowel tolerance is reached, this is a sign to back off the extra C. We continue to take C, but we take less and less often. It may take days to resolve illness (it depends how sick we are) but when healthy, the body needs less and “holds” less C.”

The Hydration Factor:

High-dose Vitamin C increases metabolic turnover.

To ensure these electrons reach your cells effectively, you must maintain proper osmotic pressure.

I use the Water Cures Protocol (1/8 tsp Celtic Sea Salt per 16 oz water) to ensure my “inner ocean” is primed for nutrient transport.

Take Enough C to be Symptom Free

As Dr. Andrew Saul puts it, his full recommendation goes like this:

“Take enough C to be symptom free, whatever the amount might be… but stay a few thousand milligrams under the amount that would cause loose bowels.” — Dr. Andrew Saul

This really shifted how I think about Vitamin C. It’s not about following a fixed number or a label on a bottle—it’s about learning to listen to your body.

If you’re stressed, sick, or fighting off an infection, your body’s needs might skyrocket. The idea is to take just enough to ease your symptoms without pushing it too far.

For me, this approach turned Vitamin C into something much more dynamic. It’s no longer just a routine; it’s a tool I use to support my health every single day.

Whether it’s keeping colds at bay or bouncing back faster from a tough week, the magic is in finding what works for you—and it’s always changing.

What Higher Doses of Vitamin C Looks Like

I never imagined what higher doses of Vitamin C could look like.

I later learned how doctors treating serious illness would use mega-dosing of Vitamin C, upwards of 30 grams, 50 grams and even 100 to 200 grams a day.

But the dosing varies by the individual and what they are treating.

What this made me realize is that when I thought I was taking high doses of Vitamin C, I was nowhere near what was being used in top clinics.

Nobody Can Tell You How Much Vitamin C You Need

The amount of Vitamin C you need is highly individual and depends on factors like your health, stress levels, and illness.

There’s no universal dosage because your body’s requirements change daily, influenced by physical and emotional demands.

The best way to determine your optimal dose is to use the Bowel Intolerance Method, where you gradually increase your intake until you experience mild gastrointestinal symptoms, then reduce slightly.

This personalized approach ensures your body gets the maximum benefit without exceeding what it can handle.

What is the Bowel Intolerance Method with Vitamin C

Bowel intolerance refers to the point at which your gastrointestinal system shows signs of being unable to absorb any more Vitamin C.

I first learned about the Bowel Intolerance method with vitamin C from one of my doctors.

She said that when you take Vitamin C your body will let you know.

Symptoms typically include:

  1. Gas or Bloating: Initial signs of mild intolerance.
  2. Rumblings in the Stomach: An indicator that the dose is approaching your limit.
  3. Loose Stools or Diarrhea: The clearest sign that you’ve exceeded your bowel tolerance.

This response occurs because unabsorbed Vitamin C draws water into the intestines, leading to these symptoms. It’s temporary and resolves when you reduce the dosage.

This threshold varies based on individual health, stress levels, and illness severity.

The Osmotic Signal:

Bowel tolerance isn’t just a “stomachache.”

It’s a precise biological signal.

When your transporters are saturated, the unabsorbed Vitamin C stays in the colon.

Because Vitamin C is an acid, it creates an osmotic pull, drawing water into the bowel.

This is your body’s way of saying, “Internal tanks are full; stop sending more.”

How To Use the Bowel Intolerance Method

The Bowel Intolerance Method with Vitamin C is a way to determine your optimal dosage based on your body’s tolerance.

Here’s how it works:

  1. Start with a Small Dose: Take Vitamin C in divided doses throughout the day.
  2. Gradually Increase: Increase the amount until you experience mild gastrointestinal symptoms like gas or loose stools—this is your bowel tolerance level.
  3. Adjust and Maintain: Once symptoms appear, slightly reduce the dose to a level your body can comfortably handle.

This method helps tailor Vitamin C intake for maximum absorption, especially during illness or stress when your body may require more.

Example Schedule of Vitamin C with the Bowel Intolerance Method

Here’s an example schedule for using the Bowel Intolerance Method to determine your optimal Vitamin C dose:

Day 1: Start Small

  • 8:00 AM: 1,000 mg
  • 12:00 PM: 1,000 mg
  • 4:00 PM: 1,000 mg
  • 8:00 PM: 1,000 mg
    (Total: 4,000 mg)

Day 2: Gradually Increase

  • 8:00 AM: 2,000 mg
  • 12:00 PM: 2,000 mg
  • 4:00 PM: 2,000 mg
  • 8:00 PM: 2,000 mg
    (Total: 8,000 mg)

Day 3: Continue Increasing

  • 8:00 AM: 3,000 mg
  • 12:00 PM: 3,000 mg
  • 4:00 PM: 3,000 mg
  • 8:00 PM: 3,000 mg
    (Total: 12,000 mg)

Adjust Based on Symptoms

  1. Continue increasing daily doses in 1,000–2,000 mg increments per session.
  2. Stop increasing once you experience mild bowel intolerance symptoms (e.g., gas, bloating, loose stools).
  3. Reduce your intake slightly and maintain that dose throughout the day until your symptoms improve.

For example, if you reach bowel tolerance at 16,000 mg/day, adjust to 12,000–14,000 mg/day and divide the dose evenly across the day.

Why Your Vitamin C Needs Aren’t Static

Your body’s demand for Vitamin C changes constantly because it’s water-soluble and can’t be stored for later use.

Stress, illness, activity levels, and even your diet influence how much you need every day.

  • Stress and Illness: Physical or emotional stress and infections deplete Vitamin C faster, requiring higher doses.
  • Activity Levels: Intense exercise produces free radicals, which Vitamin C helps neutralize.
  • Diet: A nutrient-rich diet with Vitamin C-packed foods (like citrus or berries) may lower your supplementation needs temporarily, while poor diets increase them.
  • Environmental Exposure: Pollution, smoking, or extreme weather also raise your Vitamin C requirements.

The takeaway?

Your needs aren’t fixed. Adjust your intake based on how you feel, what you’re dealing with, and your lifestyle.

What Has Vitamin C Already Been Proven to Do?

“The effects of this substance (vitamin C) when used in adequate amounts markedly alters the course of many diseases.” –Dr. Cathcart

Vitamin C is both versatile and safe, making it a powerful tool for preventing and treating various health conditions.

This is a pretty profound roundup of the kinds of things Vitamin C has already been proven to do:

What Has Vitamin C Already Been Proven to Do?

Based on the research from the PDF by Dr. Thomas Levy, Vitamin C has been proven to do the following:

  • Boosts Immunity: Strengthens white blood cells, reduces the severity and duration of infections (viral, bacterial, and fungal).
  • Combats Oxidative Stress: Neutralizes free radicals, protecting cells and tissues from damage caused by toxins and inflammation.
  • Treats Severe Infections: High doses help fight conditions like sepsis, pneumonia, and chronic diseases such as cardiovascular issues and cancer.
  • Detoxifies the Body: Chelates heavy metals (e.g., lead, mercury) and helps eliminate harmful toxins.
  • Accelerates Healing: Speeds up recovery from injuries and surgeries by promoting collagen production and tissue repair.
  • Acts as a Natural Antimicrobial: Provides antibiotic-like effects and functions as an antiviral and antifungal agent.

Vitamin C’s track record as a therapeutic powerhouse makes it a cornerstone for health and recovery.

Mega-Dosing with Vitamin C

Mega-dosing involves taking very high doses of Vitamin C—often far beyond the daily recommended allowance (RDA)—to achieve therapeutic effects.

It’s used to treat illness, manage chronic conditions, and support overall health by leveraging Vitamin C’s powerful antioxidant and immune-boosting properties.

How It Works

  • Doses: Typically ranges from 10,000 mg/day to 100,000+ mg/day, depending on individual needs.
  • Methods: Can be taken orally in divided doses or intravenously (IV) for more severe conditions like sepsis or cancer.
  • Bowel Tolerance: Gradually increase your intake until you reach bowel tolerance (mild gas or loose stools), then adjust slightly downward for optimal results.

Key Benefits

  • Boosts immunity and fights infections (antiviral, antibacterial, and antifungal effects).
  • Reduces oxidative stress and inflammation, supporting recovery from chronic conditions.
  • Speeds up wound healing and tissue repair.
  • Detoxifies the body by neutralizing toxins and heavy metals.

Safety

  • Vitamin C is generally safe, as excess amounts are excreted in urine.
  • The main side effect is temporary loose stools, which resolve when the dose is adjusted.
  • Those with kidney issues or certain health conditions should consult a healthcare provider before mega-dosing.

Mega-dosing is a powerful strategy for targeted health benefits, but it’s important to find the right dose for your body and needs.

How Dr. Andrew Saul Mega-Doses with Vitamin C

Dr. Andrew Sual writes:

“I take 8,000-10,000 milligrams (mg) of vitamin C orally a day when I am healthy. I take far more when I am under stress. If I am really sick, I may take up to 100,000 mg of vitamin C a day.

Two-time Nobel Prize winner Linus Pauling took 18,000 mg of vitamin C a day, and he recommended taking 6,000 to 18,000 mg per day.

For healthy children, Frederick R. Klenner, MD, recommended 1,000 mg per day per year of age, leveling off at 10,000 mg per day when the child reaches ten years of age. He recommended far more during illness.

For example, in good health, my five-year-old gets 5,000 mg of vitamin C a day and perhaps 25,000 mg per day when sick. We always divide our doses of vitamin C and take it throughout the day.”

Why Take Liposomal Vitamin C?

Liposomal Vitamin C is a breakthrough form of Vitamin C that’s designed for better absorption and effectiveness.

Unlike traditional Vitamin C, which can cause digestive discomfort at high doses, liposomal Vitamin C is encapsulated in fat-soluble particles (liposomes) that help it bypass the digestive system and deliver more directly to your cells.

Here’s why it stands out:

  • Better Absorption: Liposomes protect Vitamin C from being broken down in the stomach, resulting in higher blood levels with smaller doses.
  • Gentle on the Stomach: Ideal for those who experience bloating or diarrhea with regular Vitamin C.
  • Perfect for High Doses: Delivers near-IV-level benefits without requiring injections, making it great for chronic illness or recovery.
  • Targeted Benefits: Boosts immunity, supports collagen production, and enhances antioxidant activity efficiently.

Liposomal Vitamin C is a game-changer, especially if you need higher doses or struggle with traditional forms.

Bypassing the Transporters:

Liposomal Vitamin C is encapsulated in a phospholipid bilayer (fat).

This allows it to be absorbed via the lymphatic system, bypassing the “S-Curve” transporters in the gut.

This is why it can reach “near-IV” levels in the blood without triggering bowel intolerance.

Which Vitamin C Do I Take?

After testing numerous brands and forms of Vitamin C, I’ve narrowed it down to two favorites that suit different needs:

Liposomal Vitamin C by Core Med Science

Vitamin C

Trusted by doctors and professional athletes, this liposomal form ensures excellent absorption and gentle stomach tolerance, perfect for daily use.

Liposomal Vitamin C by NutriFlair

Vitamin C

My choice for mega-dosing, with fewer capsules required and consistent quality, making it ideal during illness or periods of high stress.

Final Thoughts: Mastering Vitamin C as a Lifelong Skill

Taking Vitamin C isn’t just about following rules.

It’s a skill you can master.

By understanding your body’s unique needs and adjusting your intake dynamically, you unlock its full potential for health and healing.

Whether you start small or dive into mega-dosing, the journey is yours to explore.

With experimentation and patience, Vitamin C could transform your health, just as it did for me.

Start today and you might be surprised by what it can do.
