Quick Summary

Natrol's fast-dissolve melatonin tablets typically contain no calories per serving, relying on minimal amounts of sugar alcohols and natural flavors for palatability.

Key Points

Zero Calories: Natrol Fast Dissolve tablets contain no calories per serving, making them suitable for calorie-conscious diets.
Minimal Ingredients: The calorie-free nature is due to the very small amounts of sweeteners and binders used in the formulation.
Not a Fast-Breaker: The minuscule amount of sugar alcohols used is unlikely to significantly impact blood sugar or break an intermittent fast.
Gummies Are Different: In contrast to the tablets, Natrol's melatonin gummies contain added sugars and have a caloric value (10-15 calories per serving).
Check Ingredients: While most fast-dissolve versions are zero-calorie, always check the product label for specific sweeteners and ingredients.
Sleep Aid with no Costly Additives: The formulation is designed for sleep support, not for added nutrition or caloric intake.
Flavor without the Guilt: The flavor comes from natural agents and minimal sweeteners, ensuring a pleasant taste without added calories.

Natrol Fast Dissolve: A Calorie-Free Choice

For many individuals tracking their daily nutrition, knowing the caloric content of everything they consume is crucial. When it comes to dietary supplements like melatonin, the question of calories, especially from additives, is common. Natrol's Fast Dissolve line of melatonin tablets is specifically formulated to be a virtually calorie-free product, appealing to those following strict diets or intermittent fasting plans.

The Zero-Calorie Count Explained by Ingredients

The reason Natrol Fast Dissolve tablets can list their calories as zero is due to the specific ingredients and their very small quantities. The main functional ingredient, melatonin, is not a significant source of calories. The other ingredients, primarily sweeteners and binders, are used sparingly to create the fast-dissolving tablet form while providing flavor. The key components include:

Sweeteners: Xylitol and Sucralose are often used. Xylitol is a sugar alcohol that, while technically containing calories, is used in such a small amount per tablet that it is nutritionally insignificant and allows for a "zero calorie" claim. Sucralose is an artificial sweetener with no calories.
Binders and Fillers: Ingredients like Maltodextrin, Dextrose, and Cellulose Gum are used to hold the tablet together and create its quick-dissolving texture. Although these are carbohydrates, the total amount per tablet is negligible, resulting in a rounded-down calorie count of zero.
Natural Flavors and Colors: Flavoring agents and colorants like Beet Root Extract are also added but contribute no meaningful caloric value.

Comparison: Natrol Fast Dissolve vs. Melatonin Gummies

The calorie-free nature of the fast-dissolve tablets stands in stark contrast to other forms of melatonin supplements, particularly gummies. The added sugars required to create a chewy, palatable gummy make them a caloric source that dieters need to account for. Here is a comparison to highlight the difference:


Feature	Natrol Fast Dissolve Tablets	Natrol Melatonin Gummies (Typical)
Caloric Content	0 calories per tablet	10-15 calories per serving (2 gummies)
Primary Sweetener	Sugar alcohols (Xylitol) or artificial sweeteners (Sucralose)	Added Sugars (e.g., Corn Syrup)
Form	Fast-dissolving tablet	Soft, chewy gummy
Speed of Absorption	Rapidly dissolves in the mouth	Chewed and swallowed
Target Audience	Calorie-conscious, fasting individuals	Users prioritizing taste and convenience

Common Ingredients in Natrol Fast Dissolve

The ingredients listed on the packaging help confirm the minimal caloric impact of the tablets. For example, a typical ingredient list includes:

Melatonin
Xylitol
Cellulose Gum
Maltodextrin
Dextrose
Crospovidone
Modified Food Starch
Malic Acid
Natural Flavor
Stearic Acid
Beet Root Extract (Color)
Magnesium Stearate
Citric Acid

The formulation may vary slightly between products or flavors, but the consistent theme is the absence of significant caloric sources like sugar.

Impact on Fasting and Blood Sugar

For those engaging in intermittent fasting, a zero-calorie supplement is highly desirable. Natrol Fast Dissolve tablets fit this requirement. While a supplement containing sweeteners like Xylitol could theoretically have a minor effect on blood sugar, the quantity is so minuscule that it is unlikely to have a practical impact or break a fast. In contrast, gummies with their higher sugar content would certainly break a fast. It is always wise for individuals with diabetes or concerns about insulin resistance to check with their healthcare provider, but for most, the fast-dissolve tablets are considered safe from a caloric standpoint during a fasting window. More information on melatonin's potential effects on glucose metabolism can be found from studies indexed by institutions like the National Institutes of Health.

Conclusion

For anyone concerned about adding unnecessary calories to their diet, Natrol Melatonin Fast Dissolve tablets are a reliable and well-documented choice. With a negligible caloric footprint, they provide a sleep aid without impacting your diet or fasting goals. The calorie content is zero, a fact that is consistently reported across product listings and nutritional databases. Users can take this supplement with confidence, knowing they are consuming a product that prioritizes sleep support without added sugars and significant calories.
