Why Citric Acid Is Used in NAD+ Dissolvable Strips

Citric Acid plays an important behind-the-scenes role in NAD+ dissolvable strips by helping maintain stability, balance flavor, and support smooth dissolution in the mouth. In a buccal delivery format, where the strip dissolves directly against the oral lining, even small formulation details can influence how consistently and comfortably NAD+ is delivered. Citric Acid helps create the right conditions for this process to work effectively.

In products like Recharge NAD+ Buccal Strips, Citric Acid is included deliberately to support both product performance and user experience.

What Is Citric Acid?

Citric Acid is a naturally occurring organic acid found in citrus fruits such as lemons and oranges. It is widely used in food, supplements, and pharmaceutical formulations because it:

• helps regulate acidity (pH)
• improves stability of sensitive ingredients
• enhances flavor balance
• supports consistent dissolution

Because it is well understood and gentle, Citric Acid is commonly used in oral and dissolvable delivery systems.

Why pH Balance Matters in NAD+ Buccal Strips

NAD+ is a sensitive molecule. Its stability and performance depend heavily on the environment in which it is delivered.

In dissolvable strips:

• overly alkaline conditions can reduce stability
• overly acidic conditions can cause irritation
• balanced pH supports smooth dissolution and absorption

Citric Acid helps maintain this balance, creating an environment where NAD+ can remain stable while the strip dissolves at the intended rate.

How Citric Acid Supports NAD+ Delivery

1. Helps Stabilize NAD+ During Storage

Moisture, air, and pH fluctuations can affect sensitive compounds like NAD+.
Citric Acid helps:

• regulate internal acidity of the strip
• reduce degradation risk
• support longer shelf stability

This ensures that each strip remains consistent from the first use to the last.

2. Supports Predictable Dissolution in the Mouth

A dissolvable strip must hydrate and dissolve evenly once placed in the cheek.

Citric Acid contributes to:

• uniform hydration
• controlled breakdown of the film
• smoother activation of the strip

This helps NAD+ release consistently during the dissolve phase.

3. Enhances Flavor Balance Without Excess Sweetness

Citric Acid provides a mild, clean tartness that:

• balances sweeteners like sucralose
• complements natural flavors such as lemon oil
• prevents flat or artificial taste profiles

This makes the strip more pleasant to use while avoiding excess sweetness.

4. Supports Saliva Activation

Mild acidity can gently stimulate saliva flow.
This helps:

• activate the strip faster
• improve hydration of the film
• support consistent buccal contact

While subtle, this effect contributes to smoother NAD+ delivery.

Why Citric Acid Is Especially Useful in Buccal Strips

Citric Acid is far more functional in oral dissolving formats than in traditional capsules.

The Role of Citric Acid in Recharge NAD+ Buccal Strips

Recharge NAD+ uses Citric Acid to:

✓ Maintain optimal pH for stability

Protects NAD+ throughout the product’s shelf life.

✓ Support smooth, even dissolution

Ensures the strip dissolves consistently in the mouth.

✓ Improve flavor clarity

Balances tartness, sweetness, and citrus notes.

✓ Enhance overall usability

Encourages full dissolve time for effective delivery.

Citric Acid works alongside DL-Malic Acid, Lemon Oil, Vegetable Glycerin, Pullulan, and HPMC to create a well-balanced delivery system.

Is Citric Acid Safe in Dissolvable Strips?

Yes. Citric Acid is widely used in:

• food products
• oral supplements
• dissolvable films
• pharmaceuticals

When used in controlled amounts, it is gentle, well-tolerated, and suitable for daily use.

Final Thoughts

Citric Acid may be a small component of NAD+ dissolvable strips, but its role is essential. By helping regulate pH, supporting stability, improving flavor balance, and encouraging smooth dissolution, it helps ensure that NAD+ is delivered efficiently and comfortably.

In Recharge NAD+ Buccal Strips, Citric Acid supports a clean, reliable, and user-friendly delivery system — proving that effective NAD+ supplementation depends as much on formulation precision as it does on the active ingredient itself.
