How Vegetable Glycerin Supports Moisture, Flexibility, and Smooth Delivery in NAD+ Dissolvable Strips

Vegetable Glycerin might look like a simple supporting ingredient, but in dissolvable NAD+ strips it plays a crucial role in how the strip feels, dissolves, and delivers its active compounds. As a natural humectant, it helps keep the strip moist, flexible, and comfortable in the mouth, which directly affects how easily Recharge NAD+ Buccal Strips activate and absorb.

This ingredient is essential for creating a smooth, user-friendly experience while also enhancing the overall effectiveness of buccal delivery.

What Is Vegetable Glycerin?

Vegetable Glycerin (also called glycerol) is a plant-derived compound made from natural oils like coconut, soy, or palm. It is known for:

  • its ability to attract and retain moisture
  • a mildly sweet taste
  • its smooth, syrup-like texture
  • excellent stability in oral and topical products

Because it is gentle, safe, and highly compatible with the body, it is widely used in:

  • dissolvable films
  • oral strips
  • supplements
  • skincare products
  • syrups
  • pharmaceuticals

In NAD+ strips, Vegetable Glycerin is one of the ingredients that determines how pleasant — and effective, the strip feels.

How Vegetable Glycerin Supports NAD+ Delivery

1. Keeps the Strip Moist, Flexible, and Easy to Handle

A dissolvable strip must be:

  • flexible (not brittle)
  • stable in room-temperature storage
  • comfortable to place on the buccal lining
  • able to maintain its structure

Vegetable Glycerin provides the ideal moisture content, ensuring the strip:

  • does not crack
  • stays smooth and flexible
  • holds together while being applied
  • dissolves evenly once inside the mouth

This is essential to delivering NAD+ consistently.

2. Supports Smooth and Even Dissolution in the Mouth

Once placed between the cheek and gum, the strip must melt at the right speed, not too fast, not too slow.

Vegetable Glycerin helps regulate:

  • hydration speed
  • mouthfeel
  • the melt profile of the strip

This gives users a smoother experience and creates a stable environment for NAD+ to enter the bloodstream.

3. Enhances Mouthfeel and Comfort

Some delivery systems feel chalky, dry, or sticky.
Vegetable Glycerin prevents that.

It provides:

  • a soft texture
  • gentle sweetness
  • a smooth dissolve
  • a pleasant feel on the oral mucosa

This improves compliance, users are more likely to use the product regularly if it feels good.

4. Helps Protect NAD+ From Dryness-Related Degradation

If a film becomes too dry, the structure can crack and expose NAD+ to air or moisture fluctuations.

Vegetable Glycerin stabilizes the film by:

  • maintaining ideal moisture levels
  • preventing brittleness
  • reducing oxidation risk
  • supporting ingredient integrity

This helps NAD+ remain potent and evenly distributed.

Why Vegetable Glycerin Is So Important for Buccal Delivery

In oral capsules, glycerin has minimal effect.

But in dissolvable buccal strips, it is essential:

Role Capsules Dissolvable Strips
Moisture retention Not needed Critical
Film flexibility Irrelevant Essential
Influence on absorption None Indirect but meaningful
Texture / taste Not applicable Very important
Stability benefits Minimal High

Vegetable Glycerin is practically a foundation ingredient for dissolvable film performance.

Benefits of Vegetable Glycerin in Recharge NAD+ Buccal Strips

The formulation used in Recharge NAD+ relies on Vegetable Glycerin to:

✓ Maintain softness and smooth texture

Users experience a comfortable, easy-to-place strip.

✓ Support optimal dissolve rate

The strip melts clearly and predictably inside the mouth.

✓ Improve taste and overall mouthfeel

Helps balance the tartness provided by DL-Malic Acid.

✓ Preserve structural integrity

Prevents cracking and keeps NAD+ evenly distributed.

✓ Enhance product stability

Supports the performance of other film-forming agents like Pullulan and HPMC.

Together, these improvements allow NAD+ to activate efficiently once the strip contacts the buccal membrane.

Is Vegetable Glycerin Safe?

Yes — it is widely recognized as safe and well-tolerated.
It is commonly used in:

  • oral medications
  • dissolving films
  • cough syrups
  • herbal supplements
  • food products
  • cosmetics

It is gentle, plant-based, and suitable for daily use.

Final Thoughts

Vegetable Glycerin is far more than a humectant.
It shapes how the NAD+ strip feels, how it dissolves, and how consistently it delivers its active ingredients. By keeping the strip moist, flexible, and stable, it ensures that Recharge NAD+ Buccal Strips perform smoothly from the moment a user applies them.

When paired with supporting ingredients like Pullulan, HPMC, Sunflower Lecithin, and Beta Cyclodextrin, Vegetable Glycerin helps create a modern, clean, and efficient NAD+ delivery system.
