What’s Really in Your Supplements? Your Guide to Finding Clean Formulas

Look on the back of almost any supplement bottle and you’ll find a list most people skip: Other Ingredients.

It’s small, easy to overlook, and often printed in a faint font. But despite how insignificant it seems, this part of the label can be just as important to product quality as anything on the front.

Every ingredient listed serves a purpose in manufacturing: helping powders flow smoothly, fill capsules evenly, or hold together so each dose is consistent. From fillers to flow agents to binders and manufacturing lubricants, supplements often contain far more additional ingredients than people realize. Most manufacturers simply follow the status quo and rarely look for better alternatives, and because these materials are rarely explained, most consumers don’t understand why they’re included at all.

Understanding what goes into your supplements should be part of choosing one. This article explains why additional ingredients exist and how they can help you decide whether a supplement is made with care and integrity.

Capsules Versus Tablets: Why the Format Matters

Powder supplements are typically made as either tablets or capsules, and while both formats use similar supporting ingredients, the way they are manufactured is very different. So why choose one over the other?

Tablets: More Structure Means More Additives

Tablets are extremely common in the industry and are created by pressing powder into solid shapes. However, the compression process requires several supporting ingredients to help the powder bind together, which is simply not required in capsule formulas. Tablets also often receive an outer coating to make them smoother and easier to swallow, which naturally leads to a longer list of “Other Ingredients.”

Capsules: Less Compression, Fewer Extras

Capsule-based products are simply shells filled with powder. Because the capsule itself provides the structure, the formula inside typically doesn’t require binding agents, resulting in fewer additional ingredients overall. The main additives used in capsules are focused on flowability, ensuring the powder fills evenly and each capsule is consistent and accurately dosed.

Why This Matters

Once you understand how each format is made, it becomes clear why tablets almost always require more added ingredients, while capsules allow for cleaner, more streamlined formulations. For anyone seeking to minimize extras, the format alone can be a meaningful part of the decision.

Why Capsule Size Can Be Misleading

It’s a common misconception that when two supplements list the same strength, the larger capsule must contain more of the main ingredient.

When brands work with contract manufacturers, they often have limited influence over the manufacturing choices being made. Many facilities rely on standardized production methods designed for speed and efficiency, processes that tend to run best with larger capsules and formulas containing more supporting ingredients to help powders move smoothly through equipment.

So when you’re comparing two supplements with the same strength, a noticeably larger capsule almost always contains more added material, not “more of the good stuff.” And in many cases, a smaller capsule reflects a cleaner, more streamlined formula.

Why the Shortest ‘Other Ingredients’ List Usually Wins

Want a quick shortcut for spotting a cleaner supplement?

Skip the front label and go straight to the tiny Other Ingredients section.

You don’t need a science background.

You don’t need to memorize every additive.

Just look at how long the list is.

Most of the time, the shorter the list, the cleaner the formula.

Why fewer extras are usually better

A short list, often just one or two supporting materials, suggests that:

• The formula isn’t padded with unnecessary bulking agents
• The ingredient naturally runs well on manufacturing equipment
• The manufacturer isn’t relying on excessive processing aids
• Each capsule is primarily filled with what you intended to buy

A clean formula is simple on purpose. If you’re taking a single-ingredient supplement, the Other Ingredients list shouldn’t read like a paragraph.

Some powders genuinely need help.

Not all powders behave the same. Some are sticky, some have very low density, and others simply don’t move smoothly through manufacturing equipment. In those cases, a small amount of supporting material helps the powder settle evenly and ensures each capsule receives the correct amount.

So yes, sometimes added ingredients are necessary.

But necessary is not the same as excessive.

When a long list becomes a red flag

If two brands are selling the same ingredient and one bottle has:

1–2 other ingredients
and the other has
5–7 other ingredients

That’s when it’s worth asking why.

More About Bestvite: A Commitment to Purity, Transparency, and Purpose

Over 15 years ago, Bestvite was founded after a conversation between two brothers, a doctor and a pharmacist, who shared a simple but powerful goal: to create supplements they could wholeheartedly stand behind.

At the time, growing research and industry discussion raised questions about common additives like magnesium stearate, used by many brands to speed up manufacturing rather than improve product quality. The brothers knew there had to be a better way, and that belief became the foundation of Bestvite.

Unlike most supplement brands, which rely entirely on contract manufacturers to develop and produce their formulas, Bestvite manufactures its own products, giving the company full control over ingredients, quality, and formulation decisions, a rare advantage in the supplement industry. This independence allowed Bestvite to challenge what had long been considered “normal” in capsule production and pursue cleaner, more intentional standards from the very beginning. You’ll notice this reflected on the label, with Bestvite products often having unusually short Other Ingredients lists and, when possible, smaller capsule sizes.

If an ingredient doesn’t serve your health, it doesn’t belong in your supplement.

This philosophy of avoiding shortcuts, including only what is necessary, and prioritizing ingredient integrity continues to guide every product Bestvite makes. It is the reason customers can trust exactly what they are putting into their bodies, and just as importantly, what they are not.

And when a minor supporting ingredient is needed to ensure consistency, Bestvite uses only straightforward, familiar components rather than taking shortcuts. Every product is then encapsulated in an NSF GMP–certified facility in the United States, where it is independently verified to meet FDA-compliant standards for safety, cleanliness, and quality control.

What began as a small idea discussed around the family dinner table has grown into a line of more than 140 products, all crafted with the same principles the company started with: clean formulations, thoughtful sourcing, complete transparency, and affordable prices. And despite the expansion, every ingredient is still carefully selected, every batch is tested, and every capsule reflects the dedication to purity that has defined Bestvite from the beginning.
