Woman taking a probiotic or prebiotic supplement capsule

The human digestive system is a complex mechanism, responsible for the absorption of nutrients, the removal of toxins, and fighting off certain ailments. In addition to having a healthy diet of leafy greens and other fibrous foods, one of the best ways to ensure that your digestive tract remains healthy and functional is to take a prebiotic, probiotic, or postbiotics supplement.

But, what exactly does a prebiotic, probiotic, and postbiotic do for your body? In this article, we are going to go over some of the most frequently asked questions about prebiotics, probiotics, and postbiotics in relation to gastrointestinal health.

Frequently Asked Questions (FAQs): Prebiotics, Probiotics, and Postbiotics

Prebiotics, probiotics, and postbiotics are a powerful trio when it comes to health and wellness. Here’s what you need to know to make the most of them.

Q. What are they?

Microbes inhabit our bodies, and many of them are beneficial to our health. Understanding the difference between probiotics, prebiotics, and postbiotics can help you understand how they impact your overall digestive health.

In short, prebiotics, probiotics, and postbiotics are types of beneficial bacteria that help us maintain a healthy intestinal microbiome.

If we eat processed foods, get stressed out often, and don’t take care of ourselves properly, our intestinal microbiome can become imbalanced. This can lead to a whole bunch of unpleasant symptoms later down the road.

However, if we eat a balanced diet, take probiotics and other supplements (preferably natural), and try to minimize stress in our lives as much as possible, then chances are that we’ll be able to keep our intestinal microbiome healthy.

Here are the differences between prebiotics, probiotics, and postbiotics:

  • Prebiotics – Prebiotics are food for probiotics, and there are many foods that have prebiotics in them. Prebiotics help the probiotics grow within your gut, so there is no way to have one without the other. Some examples of prebiotic foods include asparagus, bananas, barley, onions, artichoke, garlic, and oats.
  • Probiotics – Probiotics are living organisms that stay in your gut. There are roughly 39-300 trillion of them! Probiotics help your digestive system by breaking down food and absorbing nutrients.
  • Postbiotics – Postbiotics are the byproduct of probiotic bacteria when they die off or break down in your gut. They help with digestion by aiding in the absorption of vitamins and minerals. Postbiotics also help fight bad bacteria in your body before it becomes a problem.

Functions of Prebiotics Functions of Probiotics

Q. When should you use them?

Prebiotics, probiotics, and postbiotics should be taken daily! If we didn’t have the recommended amount of prebiotics, probiotics, and postbiotics in our system, we would have a problem digesting non-fibrous foods. This can lead to bloat, constipation, and Irritable Bowel Syndrome (IBS).

Q. How do they work?

Each of us has our own unique microbiome, which is shaped by factors like genetics, diet, and lifestyle. Recently, scientists have learned that the gut microbiome can be affected (in a good way) by taking either prebiotics or probiotics.

But, how do they work?

Prebiotics, probiotics, and postbiotics work in unison to give you healthy digestion. Probiotics are live microorganisms that live in the gut, and prebiotics are what feed them. Postbiotics are the remains of those probiotics after they’ve done their jobs, and they’re known to help with everything from weight management to healthy skin to diarrhea.

Q. What natural foods are they found in?

Prebiotic and Probiotic foods

Some of the most popular foods that contain probiotics are yogurt, kefir, kombucha, and sauerkraut. Food with prebiotics includes garlic, onions, artichokes, asparagus, cabbage, bananas, and, lentils. Foods known to have probiotics and prebiotics are needed in order to promote the growth of good, digestive bacteria in your gut.

All in all, consuming vegetables, lentils, fruit, and fermented foods is the way to go if you are looking to have a happy digestive system!

Q. Do supplements work?

Yes! Unfortunately, many of us have a less-than-perfect gut microbiome due to the modern diet (lots of refined foods and artificial ingredients, not enough fiber), environmental toxins, and stress.

Although probiotics and prebiotics can be found in certain foods, it can be difficult to get enough of them through diet alone. A supplement can help ensure you get enough to keep your gut bacteria happy and healthy.

Q. Should you take them with food or without food?

Some manufacturers say to take prebiotics or probiotics on an empty stomach, but some research shows that it doesn’t really matter. Do whatever the manufacturer says because the manufacturer may have optimized the supplement to work in a certain way. However, taking it with or without food is better than not taking it at all.

Q. Are there medications or foods you should avoid when taking pre or probiotics?

If you are wanting to start taking a prebiotic, probiotic, or postbiotic supplement, you should avoid taking it with antibiotics. The reason is that antibiotics can hinder the supplement from optimally working in your digestive system.

If prescribed an antibiotic by a doctor, try taking your supplement about 2-3 hours before or after the antibiotic.

Capsule manufacturing requires precision and a bit of science if the final product is to be effective. The size of a supplement’s capsule is determined by the density of ingredients it contains, but there are some other general rules of thumb to follow as well.

In this article, we are going to go over the key differences between capsule sizes, the most comfortable capsule size for your end consumer, and more.

Average Capsule Size Chart: Length & Diameter

When looking at the capsule size, we take a few things into consideration including length, diameter, capacity, mass, and powder density. In Exhibit 1, you will see how to configure the length and diameter of your capsule. This will help you effectively use the length and diameter capsule size chart.

Capsule manufacturing dimensions

Exhibit 1 – Capsule length and diameter

After you have an understanding of how the capsule is measured, you can then use Exhibits 2 and 3 to help you determine the size of the capsule you need. The higher the number the smaller the capsule, so size 3 is much smaller than the capsule size 000.

Keep in mind that the wider the diameter and the longer the pill the harder it will be for your end consumer to swallow it. This is why selecting an optimal capsule size is crucial for the success of your supplement business.

Average Capsule Size Chart: Capacity & Mass

Not only is it important to consider length and diameter before manufacturing supplement capsules, but you will also want to keep capsule capacity and mass in mind as well.

What is capacity exactly? To simplify it, your capacity addresses how much product your capsule can hold.

Although it would be ideal to select a smaller capsule for your end consumer, you may need to select a larger capsule to manufacture if the product going into the capsule exceeds your desired capsule size.

Another factor to consider is powder density. Powder density is exactly what the name suggests: it indicates how dense (or compact) your powder is. Exhibit 5 is a great representation of the different levels of supplement density.

After finding out how dense your powder is, you can use Exhibit 6 to help you further select a capsule size that’s right for your end product.

Why Size 00 Capsules?

In capsule manufacturing, sizes 00 and 0 are the most common capsule sizes because they are large enough to fit the product but also easy for individuals to swallow. As mentioned earlier, a smaller capsule is ideal, but too small and the product may not fit proportionally. We commonly use size 00 capsules because they allow several ingredients in one easy-to-take capsule.

Capsules and tablets in wooden spoon next to fruite

If you’ve been in the supplement industry for any length of time, you’ve probably encountered both capsules and tablets. But, if you’re new to the industry, it is likely that you aren’t always clear on what makes each one different. Here is a short run-down of their key characteristics to help you better understand the difference between capsules and tablets.

Supplement Capsules vs. Tablets: How They Differ

Supplements come in both the form of a tablet or capsule. Many of us take supplements in capsule form and think they are the same thing as their tablet counterparts because they look similar. Although they have commonalities, there is a distinct difference between the two. Let’s dive in.

What is a Capsule?

A capsule is an enclosed hard or soft-soluble container made up of gelatin, cellulose, or other materials that are easy to digest. The main difference between capsules vs. tablets is the way your supplement ingredients are “housed”. A capsule houses the ingredients in an exterior casing while a tablet does not.

With supplements, two types of capsules are common in the industry: hard-shelled capsules and soft-gel capsules.

Capsule Types: Hard-Shelled Capsules

Hard-shelled capsules

A hard-shelled capsule consists of two halves to create a soluble casing. These two halves are called the body and the cap. These two pieces to the capsule fit into each other seamlessly—encasing the ingredients of the supplement. Hard-shelled capsules are a great option for dual-action or extended-release formulas.

Capsule Types: Soft-Gel Capsules

soft-gel capsule

A soft-gel capsule looks similar to hard-shelled capsules, but this type of capsule contains ingredients suspended in gelatin or other similar mediums. It is quick to release and absorb supplement ingredients.

Pros of Capsules

So, why do supplement companies choose capsules? Some of the pros of capsules include:

  • Higher Bioavailability – Capsules are fast-acting and absorb in the body quicker than tablets
  • No Taste – With capsules, you won’t be left with a bad taste in your mouth after taking it
  • Tamper-Proof – Capsules can’t be altered like tablets can be

Now that we went over everything you need to know about capsules, let’s talk about tablets.

What is a Tablet?

Tablets are another common way to house supplements. Tablets are made by compressing the powdered ingredients with a binding agent to form a solid pill. Some of the most common binding agents include starch, cellulose, or methocel.

Pros of Tablets

What are the biggest pros of selecting tablets over capsules? Tablets have many advantages such as:

  • They can be formulated in a variety of shapes (flat, round, or oval)
  • They’re inexpensive compared to capsules
  • Tablets can easily be split down the middle (if needed)
  • They have a longer shelf-life

After learning about both the specifics of capsules and tablets, you are probably curious about the manufacturing process. As a premier supplement manufacturer, we are the perfect source to walk you through it.

How It’s Made: Supplement Capsules

There are many steps that we undergo to ensure that we provide you with quality capsules. To simplify it, we’ve broken the process down into these 3 steps:

Step 1: The first step in the manufacturing process is to create the shell for the capsule. A machine drops the mixture into individual molds. The mixture hardens and takes the form of a capsule. It is then sent through a machine that removes any air bubbles from the capsules.

Step 2: Once the empty shells are created, they are filled with ingredients. They enter a machine that carefully fills each capsule with its contents. Afterward, they are sent through another machine that seals the capsule shut.

Step 3: At this point, it’s time for quality control. A random sample of finished products is tested to make sure they meet label requirements and contain no contaminants or microbes that could harm consumers. If they pass inspection, they are released to be packaged and sold.
