What is Herbalife Niteworks® and what does it do? Herbalife Niteworks® is an advanced nighttime cardiovascular dietary supplement developed in scientific collaboration with Dr. Louis Ignarro, Nobel* Laureate in Medicine. Formulated with a synergistic blend of L-Arginine and L-Citrulline, it stimulates the body's natural production of Nitric Oxide (NO)—a vital signaling molecule that helps blood vessels stay flexible, elastic, and relaxed.* Because bodily nitric oxide levels naturally plunge to their lowest point during the night, taking Niteworks® before bedtime supports uninterrupted vascular dilation, healthy blood circulation to the heart, brain, and organs, and restful sleep with calming Lemon Balm extract.*
The Nobel Prize Discovery That Changed Cardiovascular Science
In 1998, the Nobel Prize in Physiology or Medicine was awarded to pharmacologist Dr. Louis Ignarro (along with Robert F. Furchgott and Ferid Murad) for an extraordinary scientific breakthrough: discovering that a simple, fleeting gas—Nitric Oxide (NO)—acts as a fundamental signaling molecule in the human cardiovascular system.
Until that discovery, scientists believed nitric oxide was merely an environmental byproduct. Dr. Ignarro demonstrated that the smooth endothelial cells lining the inside of our blood vessels naturally produce nitric oxide to command surrounding arterial smooth muscle to relax, expand, and allow oxygen-rich blood to flow unimpeded.
Dr. Ignarro subsequently joined the Herbalife Nutrition Advisory Board and collaborated exclusively with Herbalife's research and development team to create Niteworks®: a clinically formulated powdered dietary supplement designed to nourish and sustain the body's natural nitric oxide synthesis.*

Why Nitric Oxide Declines as We Age: The Endothelial Reality
When you are young, your blood vessels are remarkably pliable, elastic, and smooth—much like flexible silicone tubing. The endothelial lining produces abundant nitric oxide on demand, keeping blood pressure within normal ranges and delivering vibrant energy to every organ.
However, as part of the natural biological aging process:
- By age 40: The body's endothelial nitric oxide synthase (eNOS) activity drops by an estimated 30% to 35%.
- By age 50 to 60: Endogenous nitric oxide bioavailability can decline by over 50% compared to your twenties.
- Accelerating Factors: Sedentary lifestyles, modern processed American diets high in refined sugars, chronic stress, and environmental free radical damage deplete nitric oxide reserves even faster.
When nitric oxide drops, arteries become stiffer and less responsive to changes in blood volume. Supporting your body's natural NO production helps preserve arterial elasticity, maintain healthy microcirculation, and ensure adequate oxygen delivery throughout the entire vascular tree.*
Herbalife Niteworks® Lemon (10.6 oz / 300g)
The premier 30-serving monthly supply. Delivers an exclusive amino acid blend of L-Arginine and L-Citrulline combined with antioxidant Vitamins C and E, Alpha-Lipoic Acid, and calming Lemon Balm to support heart, brain, and circulatory wellness while you sleep.*
Why Take Niteworks® at Night? The Circadian Protection Window
One of the most frequent questions from consumers is: "Why is Niteworks® formulated as a nighttime supplement rather than taken with breakfast?"
The answer lies in chronobiology—the study of biological rhythms. Medical research confirms that the body's internal synthesis of nitric oxide is not uniform throughout 24 hours. In fact:
- The Overnight Dip: Endothelial production of nitric oxide drops to its lowest biological level while you are asleep, reaching a critical low during the early morning hours (between 4:00 AM and 8:00 AM).
- The Morning Vulnerability Window: Statistically, the early morning hours represent the highest period of cardiovascular stress, as blood pressure and heart rate naturally surge to wake the body up, precisely when nitric oxide levels are at their nadir.
- Sustained Overnight Replenishment: By drinking Niteworks® 30 to 60 minutes before bed, you flood your bloodstream with L-Arginine and L-Citrulline, ensuring a continuous substrate supply for nighttime nitric oxide synthesis while your cardiovascular system rests and repairs.*
- Restorative Sleep Synergy: Herbalife also infused Niteworks® with natural Lemon Balm extract (Melissa officinalis), a botanical traditionally prized for calming the nervous system, quieting restless thoughts, and facilitating deep, rejuvenating sleep.
Inside the Formula: The Synergistic Active Ingredients
Niteworks® is not just a generic L-Arginine powder. Its biological efficacy stems from a precision-engineered cascade of complementary ingredients designed to overcome the natural chemical instability of nitric oxide:
L-Arginine
The essential direct precursor amino acid utilized by vascular endothelial cells to produce nitric oxide gas, facilitating prompt arterial relaxation and vasodilation.*
L-Citrulline
A secondary amino acid that bypasses hepatic metabolism and recycles back into L-Arginine, creating a sustained-release nitric oxide cycle that lasts through the entire night.*
Vitamins C & E
Nitric oxide is destroyed in fractions of a second by oxidative free radicals. Potent antioxidant Vitamins C and E neutralize free radicals and preserve nitric oxide's biological lifespan.*
Alpha-Lipoic Acid (ALA)
A universal lipid- and water-soluble antioxidant that rejuvenates Vitamins C and E, supporting vascular endothelial health and energy production.*
Lemon Balm Extract
A soothing European botanical (Melissa officinalis) that calms the mind, encourages peaceful relaxation, and promotes high-quality, undisturbed sleep.
Folic Acid (Vitamin B9)
Crucial B-vitamin cofactor that aids in maintaining healthy homocysteine levels already within normal range, preserving vascular elasticity.*

Frequently Asked Questions About Herbalife Niteworks®
1. Does Herbalife Niteworks® contain caffeine or stimulants?
No, Niteworks® is 100% caffeine-free and stimulant-free. It will not keep you awake or cause jitters. In fact, it contains Lemon Balm extract, a natural botanical known for its calming, relaxing properties that encourage restful, restorative sleep.
2. Who can benefit most from taking Niteworks®?
Niteworks® is ideal for adults aged 30 and older seeking proactive cardiovascular wellness, individuals looking to maintain arterial flexibility and healthy circulation, masters athletes wanting enhanced blood flow and stamina, and anyone looking to optimize nighttime recovery and cellular vitality.*
3. Can athletes take Niteworks® before working out?
Yes! While originally formulated for nighttime cardiovascular support, many endurance athletes, marathoners, and cyclists take 1 serving 30 to 45 minutes prior to aerobic exercise to support muscle oxygenation, vascular blood flow, and endurance performance.*
4. What is the difference between the 5.3 oz and 10.6 oz canisters?
The formula and ingredients are identical. The 10.6 oz (300g) canister provides 30 full servings (a complete 1-month supply), whereas the 5.3 oz (150g) canister provides 15 servings, designed as an introductory trial or a compact travel container.
5. Why are both L-Arginine and L-Citrulline needed together?
L-Arginine directly produces nitric oxide, but enzymes in the liver and digestive tract break down free arginine relatively quickly. L-Citrulline bypasses liver breakdown and recycles back into L-Arginine in the kidneys, extending the biological duration of nitric oxide synthesis throughout the 7 to 8 hours you sleep.*
6. How fast will my order ship from My Level Up Nutrition?
All orders placed on My Level Up Nutrition are dispatched directly from official Herbalife regional distribution warehouses in the United States with expedited tracked shipping (typically arriving in 2 to 4 business days) and backed by the 30-day Herbalife Gold Standard Money-Back Guarantee.
