Can Dosage Form Design Solve Your Supplement Formulation Challenges?

A Chew That Does More: start with the formula, not just the format

Dosage form isn't just about what the finished product looks like. It also shapes how much of an ingredient a product can carry, how it tastes, what processing it has to survive and how well it holds up over time. Consider it alongside the formula, and you can address dose, taste and stability together instead of one by one.

Ever had a formula that looked perfect on paper, then tasted metallic, smelled like fish oil or needed six capsules a day to hit its dose?

Those aren't finishing touches. They're early design questions.

That's why we develop Burst Chews, our dual-layer, central-filled chewables, by starting with the formula and then asking whether the format helps.

What does it mean to treat dosage form as part of the formulation?

It means treating format as a formulation variable, like ingredient and dose, and deciding it at the design stage rather than after the formula is set. In practice, as you choose ingredients and set doses, you're also asking: Will it fit? Will it taste right? Will it survive processing? Can we verify the finished product?

A 2026 peer-reviewed perspective by scientists from FDA's Human Foods Program shows the same tension in gummies. Consumers seem to want convenient, enjoyable, palatable alternatives to tablets and capsules, but the format also brings challenges in formulation, manufacturing and analytical testing.[2]

That's why choosing a format can't rest on what consumers like alone. It has to go back to the formula and ask whether the idea is technically doable.

Why does the experience of taking a supplement matter?

Because for many consumers, taking supplements is already a daily habit, and a new product usually has to fit into an existing routine. In the US, 60.2% of adults aged 20 and older used a dietary supplement in the past 30 days, and 38.7% used two or more. These CDC figures come from 4,775 adults in a nationally representative NHANES sample (August 2021 to August 2023).[1]

These numbers show supplement use, not format preference. So a few practical questions belong in your development brief:

• How many pieces make up one serving?
• Does it need water or preparation?
• Does the taste and texture suit the moment it will be taken?

For an on-the-go product, even something as simple as not needing water can shape the choice of format.[14] Whether a pleasant experience also improves long-term use is a separate question, and only consumer research on your product can answer it.

Which formulation challenges does dosage form affect?

Different ingredients have different weak spots: some come down to taste, others are sensitive to heat, oxygen or moisture. The table below shows four common examples and why format and process choices belong in the picture from the start.

What does a process feature actually prove?

A process feature tells you how a product is made. Testing tells you whether the finished product meets its specifications, and still does at the end of its shelf life. That's why low temperature, vacuum and central filling are tools, not conclusions.

In the US, dietary supplement CGMP rules require manufacturers to set specifications for each finished batch (identity, purity, strength and composition) and verify the product meets them. An expiration or best-by date isn't required, but if you print one, you should have data to back it up.[3]

Stability testing tells you how a specific formula holds up in its intended package. If the formula or the package changes, it's worth checking whether the results still apply.

Take a probiotic. The question isn't only how many live cells go in. It's how many are still viable at the end of shelf life, and only stability testing of the finished product can show that.

These checks may seem unrelated to dosage form, but they're tied together: the same ingredient can behave differently in a different format, process or package.

How do common supplement formats compare?

No format wins every brief, so treat the table as a starting guide, not a ranking.

When choosing a format, the real question isn't "which is best?" but "which fits this formula best?"

What are Burst Chews, and where do they fit?

Burst Chews are Boncha Bio's central-filled, dual-layer chewable format, known in Chinese as 咀嚼粒. A chewy outer layer surrounds a central filling.[8] Having two parts gives formulators separate spaces to work on flavor, texture and ingredient placement.

We use a low-temperature, vacuum-based process. Our technical white paper cites roughly 40°C (about 104°F), with vacuum filling designed to reduce oxygen exposure.[9] Exact conditions vary by formulation and step.

What the dual-layer design makes possible

The outer layer and central filling give formulators two distinct regions for placing ingredients with different formulation needs. That flexibility can help when exploring combinations that are hard to manage in a single, uniform matrix. Placement isn't isolation, though: moisture and oxygen can still move between layers, so each combination needs its own stability testing.

Pairing lutein with algal oil in the same chew is one example. Our current concepts show others:

For us, this is a mature part of Burst Chew development, and the format is already commercialized in the US, Taiwan, South Korea, Southeast Asia and Europe.[8]

A concept example: iron

Remember iron's metallic taste from the challenge table? Our Hero Gentle Iron Brownie Burst Chew concept tackles it by pairing a cocoa-inspired outer layer with an iron-containing central core, designed to help mask metallic notes.

The key word is designed. You still need to define the iron source, the target elemental iron per serving and the taste goal, and only sensory testing of the finished formula can show whether the design works.

Where Burst Chews may not be the right answer

Not every ingredient belongs in a Burst Chew. Some doses suit powders or liquids better, and others raise taste-masking, stability or processing questions you'll need to solve during development. The goal isn't to replace every format. It's to add one more option, used when the brief calls for it.

How should a brand start a Burst Chew development brief?

If you already have an ingredient or product concept in mind, start with the formulation constraint and then see whether Burst Chews fit, rather than rushing to decide what format the product should take. These five questions keep things concrete:

1. Target active. Which ingredient, in what form, and for which market?
2. Serving. How much of the specified active must each serving deliver to support your intended claim? Count the active itself, not the ingredient weight: 500 mg of a standardized extract isn't 500 mg of its marker compound.
3. Main constraint. Is the hardest part taste, dose, heat or oxygen sensitivity, or the daily experience?
4. Fit. Does a dual-layer, central-filled chew help with that constraint?
5. Evidence. What finished-product testing will show the product meets its specifications and shelf-life target?

You don't need full answers in the first conversation, but the earlier you clarify them, the less back-and-forth you'll face later.

FAQ

Q1: Is a chewable supplement better than a capsule or a gummy?

A: Not always. It depends on your ingredient, dose per serving, taste challenge and stability needs. Chewables can suit products where experience and flavor matter, while capsules, powders or liquids may suit larger or simpler doses.

Q2: What are Burst Chews?

A: Burst Chews are Boncha Bio's central-filled, dual-layer chewable supplements: a chewy outer layer around a central filling, so formulators can work on ingredient placement, flavor and texture separately. One chew can also place ingredients with different formulation needs, such as fat- and water-soluble vitamins, in different regions.

Q3: Does a chewable format improve adherence or repeat purchase?

A: Format alone can't promise either. Preferences vary by consumer group and product, so treat adherence and repeat purchase as outcomes to measure, backed by research on your specific product.

Q4: Can any ingredient be made into a Burst Chew?

A: No. Very large doses, or ingredients that clash with the process or the filling, may suit other formats better. A quick feasibility review of the target amount comes first.

Conclusion: understand the formula, then choose the format

Dosage form is part of formulation science, not a decoration added at the end. Ingredient, serving, taste, process and finished-product evidence all deserve a seat at the same table.
