Herbalife Niteworks is a nutritional supplement formulated to boost the body's natural production of nitric oxide, a molecule that plays a key role in blood vessel dilation and overall cardiovascular health. The product, developed with the help of a Nobel Laureate, uses a combination of amino acids and essential vitamins to achieve its intended effects, particularly during the night when nitric oxide levels are naturally lower.
Key Active Ingredients
L-Arginine
L-arginine is a semi-essential amino acid that serves as a direct precursor to nitric oxide (NO) in the body. The body uses an enzyme called nitric oxide synthase to convert L-arginine into NO. This conversion process is vital for vasodilation, the relaxation and widening of blood vessels, which in turn improves blood flow throughout the body. Adequate blood flow is crucial for delivering oxygen and nutrients to tissues and organs, supporting overall cardiovascular health.
L-Citrulline
Often paired with L-arginine, L-citrulline is another non-essential amino acid that can be converted into L-arginine within the body. This process is beneficial because supplementing with L-citrulline can lead to more sustained increases in L-arginine levels in the blood compared to supplementing with L-arginine alone. By providing a steady supply of L-arginine, L-citrulline helps ensure continuous nitric oxide production. It is also known to help reduce muscle fatigue and enhance exercise capacity.
L-Taurine
L-taurine is an amino acid found abundantly in muscle and nerve tissues. While its role in the Niteworks formula is part of a proprietary blend, taurine is known for its role in supporting various metabolic processes. It is often included in energy drinks and sports supplements, and research has investigated its potential benefits for cardiovascular function and metabolism. Its inclusion complements the other amino acids in supporting the supplement's overall health-promoting goals.
Lemon Balm Extract (Melissa officinalis L.)
Lemon balm, derived from the plant Melissa officinalis, is included in Niteworks for its soothing and flavor-enhancing properties. This herb is traditionally used to promote calmness and support restful sleep, making it a suitable addition for a nighttime supplement. Additionally, lemon balm contains antioxidant compounds that help protect cells from oxidative stress.
Supporting Vitamins and Antioxidants
Vitamin C and Vitamin E
These two vitamins are powerful antioxidants that protect the body's cells from damage caused by free radicals. In the context of cardiovascular health, oxidative stress can harm blood vessels. By combating free radicals, vitamins C and E help preserve the integrity of blood vessels and support overall circulatory health.
- Vitamin C (Calcium-L-ascorbate): This water-soluble vitamin is essential for immune function and acts as an antioxidant.
- Vitamin E (DL-alpha-tocopheryl acetate): This fat-soluble vitamin primarily functions as an antioxidant, scavenging free radicals and protecting fats from oxidation.
Folic Acid
Folic acid (Pteroylmonoglutamic acid) is a B vitamin that is crucial for creating and maintaining new cells. Niteworks is a rich source of folic acid, which may help to improve and support the bioavailability of nitric oxide. Adequate folic acid intake is also associated with maintaining healthy blood pressure levels.
Comparison Table: Niteworks Ingredients at a Glance
| Ingredient | Primary Function | Key Benefit |
|---|---|---|
| L-Arginine | Precursor to nitric oxide | Promotes vasodilation and improves blood flow |
| L-Citrulline | Converts to L-arginine | Sustains nitric oxide production over time |
| L-Taurine | Amino acid for metabolism | Supports metabolic processes and nerve function |
| Vitamin C & E | Powerful antioxidants | Protects cells from oxidative damage |
| Folic Acid | B vitamin, cell growth | Supports nitric oxide bioavailability |
| Lemon Balm | Herbal extract | Promotes relaxation and provides antioxidants |
Inactive and Supporting Ingredients
Beyond the primary active components, Niteworks includes several inactive ingredients to create the powdered drink mix. These typically include:
- Flavour enhancer (Citric acid): Provides the citrus flavor and acts as a preservative.
- Maltodextrin: A carbohydrate used as a thickener and filler.
- Flavoring: Added for taste.
- Sweetener (Sucralose): Provides a sweet taste without calories.
- Anti-caking agent (Silicon dioxide): Prevents the powder from clumping together.
How to Use Niteworks Safely
For most products, the recommended use is to mix two scoops (10 g) of Niteworks powder with 250ml of cold water or juice. It is specifically marketed as a night-time supplement to be taken before bed, allowing the amino acids to get to work while you rest. It is crucial to follow the dosage instructions on the product label and to not exceed the daily recommended amount.
Important Warnings:
- Medical Consultation: Always consult a healthcare provider or pharmacist before starting any new food supplement, especially if you are pregnant, nursing, taking medications, or have a pre-existing medical condition.
- Not for Everyone: Niteworks is not intended for use by children, pregnant, or lactating women.
- Supplement, Not Replacement: Remember that supplements are intended to support a varied and balanced diet and should not be used as a substitute for a healthy lifestyle.
Conclusion
Herbalife's Niteworks supplement is formulated with a strategic blend of amino acids—L-arginine, L-citrulline, and L-taurine—along with key antioxidant vitamins C and E, and folic acid. The combination is designed to support the body's natural production of nitric oxide, which promotes healthy blood vessel tone and blood flow. The inclusion of lemon balm extract also adds a calming element suitable for a nighttime routine. While the supplement offers a targeted approach to cardiovascular support, it should always be used as part of a healthy lifestyle and with consideration of individual health status by consulting a healthcare professional.
