Tablet, Capsule, Liquid Or Powder: Does Your Supplement Format Matter?
One of the questions I am asked most often is whether liquids are better than capsules.
The honest answer is that no format wins outright. What matters is whether the format suits the ingredient sitting inside it. A tablet is the right call for one nutrient and the wrong call for another, and the same is true of everything else on my shelves.
Dr Edward Group at Global Healing has just published a piece on what makes a supplement highly absorbable, and it made me want to write about the part of a supplement most of us never think about. Not what is in the bottle. How it gets out of the bottle and into you.
Four things have to happen first
Before a nutrient can do anything for you, Global Healing set out four steps it has to clear. It has to be released from the supplement. It has to survive digestion. It has to cross the intestinal wall. And then it has to be in a form your body can actually put to work.
A number on a label tells you what went in. It tells you nothing about how many of those four steps the nutrient will get through. That is the whole reason delivery exists.
The formats, and what each one is good for
Tablets. Compressed, dense and stable. They suit ingredients tough enough to come through digestion without special protection, and they hold a lot in a small space. The trade-off is that the tablet has to break apart before anything can be absorbed, which is the slowest start of any format here.
Capsules. Best when you want the contents released into the digestive tract reasonably quickly. Stomach acid breaks down the shell and the powder inside is free to dissolve. Plenty of the Global Healing range works this way, including Oxy-Powder, Ultimate Enzymes and the Organic Multivitamin With Minerals.
Enteric-coated capsules and tablets. The coating is built to resist stomach acid and dissolve further along the tract instead. It is used for ingredients that stomach acid would otherwise damage, and for anything meant to be released in the intestines rather than the stomach. Certain probiotic strains are the usual example.
Liquids. The ingredients are already dissolved or dispersed, so there is no shell and no tablet to break down first. Nothing has to disintegrate before absorption can begin. This is why so much of the Global Healing range is liquid - Vitamin B12, Vitamin D3, Vitamin C, Zinc and the whole Raw Herbal Extract range. Liquids are also the easiest format for anyone who struggles to swallow capsules, which is a bigger group than people realise.
Powders. Not on Global Healing's list, but worth adding because so many of us use them. A powder gives you the volume you simply cannot fit into capsules, which is why wholefood products like Organic Super Greens and Organic Wheatgrass come this way. The trade-off is that you have to actually like drinking it.
Lipid-based delivery. Here the nutrient is carried inside a fat structure, which is there to shield it on the way through and help it cross into the body at the other end. This is what Global Healing's MicroSomal system is doing, and you will find it behind their Glutathione, Paratrex 2 and Glucose Oxidase. It is the part of a supplement you cannot see on the label at all, and it is the part Global Healing have spent the longest on.
The bit almost nobody looks at: what else is in the formula
This is the part I had not given enough thought to until I read Dr Group's piece.
Some nutrients are only useful to you when another nutrient is there alongside them. Those partners are called cofactors, and they take part in the processes that let your body activate and use what it has absorbed. Without enough of the cofactor, you can absorb a nutrient perfectly well and still be limited in what your body does with it.
Global Healing use calcium and magnesium as their example. Calcium is the one everybody knows for bones, but it does not work on its own. Magnesium is involved in regulating calcium balance and in the processes behind healthy bone mineralisation, so having enough magnesium is part of what lets the body use calcium appropriately once it is in. Which is exactly why their Calcium & Magnesium is one product and not two.
Once you start looking for it, you see the same thinking across the range. CoQ10 & BiOPQQ puts three things in one capsule on purpose, not to make the label look impressive. And the cayenne extract in their Oregano Oil is there specifically to support absorption of what is alongside it.
So when you are comparing two supplements, the extra ingredients are not automatically padding. Sometimes they are the reason the main ingredient works.
And then, plainly, how much is in there
A supplement can have the best form of a nutrient in the cleverest delivery system ever built, and none of that rescues a formula that contains barely any of it.
Three things worth doing with a Supplement Facts panel:
- Read the amount, not just the ingredient name. You should be able to see how much of each key active you are getting.
- Compare that amount against what has actually been studied in people, rather than against the other bottle on the shelf.
- Do not assume more is better. Global Healing make this point and I think it is the important one - the goal is an appropriate amount, and with some nutrients, too much brings problems of its own.
Four questions, before you buy anything
You do not need to understand the biochemistry to ask better questions. Global Healing boil it down to four, and I think they are good ones for any brand, mine included:
- Delivery. How does this product actually get its ingredients into me?
- Form. Which form of each nutrient is it, not just how many milligrams?
- Formula. Have the cofactors been thought about?
- Amount. Is there a meaningful quantity of the thing I am buying it for?
If you want the longer version of the form question, and why "vitamin B12" can mean four different compounds, I wrote about that here.
An honest note to finish
None of this makes format a ranking. A liquid is not automatically better than a capsule, and a lipid-based anything is not automatically better than a plain powder. The question is always whether the format fits the ingredient and fits you. If you will not take it, the most sophisticated delivery system in the world is worth nothing.
And supplements still will not dig anyone out of a poor diet. Wholefood first, always. Then, when you do supplement, buy from people who have thought about all four of those questions before you had to.
