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.

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.

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.

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.

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

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.

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.

From purity in formulation to honesty in labeling, Bestvite continues to be guided by the same mission that started it all: to make supplements that reflect care in every capsule, every ingredient, and every decision.

Because when it comes to your health, the smallest details matter.
