Pills, powders and potions: the reality of taking supplements while fasting

One question which persistently recurs on waterfasting.org is whether or not you should take supplements while water fasting. The majority of people want to know about vitamin supplements and, occasionally, even protein supplements. In this article I’ll deal with both, as well as other kinds of pills, powders and potions…

There are some people who take a hardline approach to water fasting – in other words water, water, only water. Personally, I do drink only water when I’m fasting, but I believe that everyone needs to find their own solutions, depending on the reasons that they’re fasting. This may include drinking herbal or green teas, or perhaps adding a slice of lemon to their water.

Taking supplements, though, is another step removed from the simple purity of drinking only water.

Vitamin supplements

Many people believe that they need to take vitamin supplements in order to live a healthy life. When it comes to fasting, this belief often takes on an added urgency. The logic – at least on the surface level – is sound, and goes something like this: ‘If I need to take vitamin supplements when I’m eating normally, then surely I need them even more when I’m not eating anything at all!’

Yes, in one sense the logic is sound. The only problem is that it’s based on the logic of your everyday working digestive metabolism and not the healing metabolism of ketosis, which takes over during a water fast and works completely differently.

I would suggest taking another approach – one which instead follows the logic of your healing metabolism:

So long as things are going into your body, toxins can’t come out of your body.

Whenever possible, it’s best just to get out of the way, and let your body get on with the business of cleansing and detox.

Okay, it’s true: toxins can’t come out of your body while food and calories are going in. It’s equally true that most vitamin supplements don’t contain calories. They won’t affect ketosis or radically change the biology of your fast. And so, in this sense, there’s nothing wrong with taking them.

Nevertheless, even if taking vitamin supplements doesn’t adversely affect ketosis, what good does it do to the fast? The truth is: little or none. They only distract your body and get in the way of natural cleansing and detox.

I’ll come out with it plain and simple: so long as you’re healthy, there’s no need to take vitamin supplements while fasting, and this is certainly the case if you don’t normally take supplements in everyday life. It’s also the case if you’re considering an extended healing fast and are worried about chronic vitamin depletion. No-one has ever died from vitamin deficiencies while fasting!

Instead, try to trust your body. It really does know best.

Humankind has been fasting for thousands of years, well before modern science came on the scene with ideas about vitamin supplements :-). I doubt our ancestors on the African savannah or in ancient India worried about it. They just got on with their fasts, trusting that their bodies would get on with the business of cleansing and detox.

It simply wasn’t a problem.

There are those who rightly say that the nutritional content of food is much lower nowadays than before monoculture (mass cultivation of one particular crop) revolutionised agriculture after World War II. This also means specifically that the vitamin content of what we eat nowadays is much lower than in the past.

Sad but true. Nevertheless, vitamin content hasn’t decreased to the point that it affects fasting. While fasting, the body conserves its essential reserves, and this includes vitamins.

If you’re worried about vitamins, a much better solution would be to eat organic in everyday life than take vitamin supplements while fasting.

Vitamin supplements for health issues

Okay, so if you’re healthy there’s no need to take supplements, but what if you already have a chronic vitamin deficiency?

This implies that you’ve already discussed the matter with your doctor. My advice, therefore, would be to return to your doctor and ask if it’s okay to stop taking vitamins temporarily: for a few days or whatever the duration is of your planned fast. If you have no other underlying health issues, there’s no need even to mention the word ‘fast’ if you feel that your doctor might panic or throw a temper tantrum – because it’s certainly true that the majority of MDs still don’t understand fasting or the benefits of fasting. Most likely, they’ll simply oppose the idea point blank. However, the reality is that in most cases skipping your vitamins for a few days won’t be a problem. Why? Because if it’s a chronic deficiency to begin with, you’ll probably need at least several weeks to regain healthy levels anyway, which means that only a few days without vitamin supplements won’t impact significantly on the long-term effect. Even so, do check with your doctor, especially if you’re planning a longer fast.

If you do have other underlying health issues which require you to take vitamin supplements, my advice would be to find a doctor who does understand fasting and discuss the particulars of your case.

The reality of taking protein supplements while fasting

This one is really easy. The answer is no, no, no!

Protein contain calories – 4 kcal/g to be exact. This is, in fact, exactly the same energy content of carbohydrates, which likewise contain 4 kcal/g.

In other words, if you’re taking protein supplements, you’re not fasting!

Why are we obsessed by the idea of taking supplements?

What causes so many of us to agonise over protein and vitamin supplements while fasting?

If you really think about it, the whole idea is crazy. Fasting means not eating. Taking supplements is its own form of eating. The two are totally contradictory.

Americans, in particular, worry about protein intake, despite the fact that the average American consumes more protein than anyone else on the face of the planet! Isn’t this also totally contradictory?

When people think and act in a contradictory manner, invariably a strong emotion is directing the decision-making process.

Nine times out of ten, fear is the driving motivation behind the belief that you ‘need’ to take supplements while fasting.

Why? Because big business has a lot of money invested in protein and vitamin supplements. Which means they have a lot of money invested in you buying their products. They want to convince you that you ‘need’ them.

How? By implanting fear: fear that without vitamin and protein supplements, you won’t make it through the day.

It’s no wonder these vested interests succeed in brainwashing so many people. Of all emotions, nothing is stronger than fear in influencing our behaviour. And given the consumer messages constantly bombarding us from ‘Big Food’, of course eventually we take the bait.

According to a recent article in the New York Times, Americans spend $30 billion dollars annually on vitamins, minerals and herbal supplements.* If protein powders are included, this constitutes as big a market as the entire organic food industry. In fact, pills, powders and other magic potions make up 5% of all grocery sales in the United States. Isn’t that crazy too?

Deeper fears

This isn’t the end of the story quite yet. Another issue attracts us to the idea of taking supplements while fasting.

The fears instilled by big business work in perfect harmony with and intensify the deeper fears already present in fasting.

It’s totally natural to feel a little fear when fasting. Going beyond your comfort zone in not eating begs the subconscious to carry this through to its logical end, which means playing with the idea of starvation and, ultimately, fear of survival and death (discussed further in my article Facing your Ego).

Even if it’s suppressed in your subconscious, the natural existential fear of fasting – that you won’t make it through the day – resonates perfectly with the fears instilled by Big Food, which likewise infer that you won’t make it through the day without spending lots of money on daily vitamin, mineral and protein supplements.

Supplements, therefore, feel like a way to cheat death. I know this may sound a little extreme, but it’s true. At the very least, anyone considering vitamin supplements while fasting does so because they fear for their health – which, in turn, is only one step away from fearing for their life. After, a total lack of health leads to a total lack of life. In other words, you fear death. Like it or not, the logic is plain and simple.

Water, pure water…

Whenever you’re water fasting and you find yourself seeking alternatives to drinking pure-and-simple water, it’s important to try and understand the reasons. This includes protein and vitamin supplements, but it also includes anything else, such as drinking herbal teas or lemon water.

There can be completely rational reasons for finding excuses not to drink water. For instance, if you have a caffeine addiction, you may find yourself attracted to the idea of green teas, as a means to prevent headaches from caffeine withdrawal symptoms. If you’re fasting for purely physical reasons, there’s nothing wrong with doing what you need to do in order to maximise the chances of finishing your fast. However, if you’re at all interested in what makes you tick, if you’re interested in understanding your subconscious and deeper levels of self, if you’re interested in trying to lead a conscious life, then you should know that usually the reason we look to alternatives besides water has nothing to do with clear logic and rationality.

We may try to justify supplements and teas through logical argument (and most of the time this isn’t too hard!), but deep down inside, there’s usually a deep dark emotion driving us instead. In order to truly make a rational decision about whether or not to take supplements, the best thing we can do is try to dig out those irrational forces inside us, bring them to light, and, making sense of them, act more consciously.

The vast majority of the time, pure-and-simple water really isn’t so bad.
In fact, it’s what we’re made of.

  1. Thank God for this site. I recently completed a 14 day water fast for my first time. It was amazing. I passed a parasite on the eighth day!!! Yes, I’m excited. hahahaha My question is now about viral diseases. I recently contracted hsv 2. have you heard of anyone eradicating this virus? I figure a cancer cell is a lot tougher than a virus. So if water fasting can take care of cancer, I’m assuming it can take care of this virus. I’m gonna shoot for another water fast but this time I’m shooting for 21 days. What are your thoughts on this virus or any viral disease that’s deemed incurable by Western Medicine.

    1. Hi Mike,
      Thanks for writing.
      To cut straight to the chase, no I don’t know anyone who has used fasting to eradicate hsv2 – whether successfully or unsuccessfully. I like your logic though:-). Unfortunately, the way a cancer cell works IS a little different from how a virus does.
      To be honest, I simply have no idea in this particular case how effective fasting will be, but do keep us posted because I’m really curious about the outcome.

      I hope you manage to beat the virus here, and a 21 day fast sounds like a good way to go. In the worst case, even if the virus persists in your body, I suspect the fast will still produce beneficial results by boosting your immune system and reducing symptoms in the process.

      Best of luck to you,

  2. Dr. Mercola says in an article that during his five-day monthly water fasts he takes in salt five or six times a day. He puts a bit of it on the palm of his hand and licks it off! The article of his which I read was more on salt use in daily life than on water fasting but do you think it holds good for water fasting too? He prefers pink Himalayan salt.

    1. My question is: taking salt five or six times a day???!!!! That seems rather excessive, don’t you think? Unless he’s sweating copiously and in danger of depleting his NaCl, I can’t imagine why anyone would do that. But I also don’t understand why anyone would be sweating to such an extent while fasting. Hmm. Do you have a reference on that article, so I can check it out and find out why on earth he’d do that?

      1. Please go to http://www.mercola.com, click on “Health” and under it “Health Articles” and enter the following in the “Search” box on top: “Why a Low-Sodium Diet Might Wreck Your Health”. The relevant paragraph is titled “The Importance of Salt When Fasting and Exercising”. I was intrigued by the whole article but nevertheless took it with a pinch of salt!

        1. Haha: a pinch of salt! Well, seeing is believing, and I just don’t understand it. Mercola is absolutely right about salt not being the only factor in causing high blood pressure. Rightfully so, much more important to health is the ratio between potassium and sodium. I’m sure he’s also right about people 500 years ago ingesting even higher levels of salt than today. For me, though, that isn’t quite convincing, because homo sapiens have been around on this planet for many tens of thousands of years, and there’s no evidence that for the vast majority of this time we ate or needed added salt in our diet.

          This applies to fasting too. Of course, you can take added salt while water fasting, but the reality is that you’re going to have to drink more water to compensate for the added salt. There IS an argument to be made for drinking only what you really need while water fasting, because whenever you put ANYTHING into your digestive system – even including water – you stimulate your digestion to some degree. Case in point:

          This last week I finished a four-day dry fast (no eating or drinking of any kind). The point is that, in my experience, dry fasts switch off your digestion much faster than water fasts – precisely because absolutely nothing is going into your body – and doing so consequently accelerates and intensifies your healing metabolism.

          The biggest reason I can see that people would take salt while fasting is addiction. Salt is clearly addictive, and most people are clearly addicted to added salt. For many people, therefore, adding salt during a fast can make you feel more grounded and secure. But it’s not going to help the fast!

          1. I am generally a bit chary of the pendulum swinging to the other extreme these days in almost every thing to with health – diets, diabetes, blood pressure, salt intake, lipid levels etc. For a couple of decades coconut oil was a villain and now it has turned hero – for someone from Kerala, India where the coconut tree is in our genes this is an awesome turnaround! Similarly fats are now laid on thick! Statins are out. Eggs are back in fashion yolk and all.

            The only sure thing I can trust seems to be fasting of various kinds which brings in varying results and for me the most suitable seems to be water fasts.

            With all the authority of a single 7-day water fast I can say that I did not need any extra reinforcements of any kind in the form of salt or coffee. I stopped taking green tea too on fast days though I do take it on other days when I feel like it, not regularly.

            I use water from a well at home – we have been using this well for three generations – boiled with a few herbs and cooled but more of that another day.
