Niteworks affects circulatory – vessel dilation and elasticity, blend with water or juice for a refreshing lemon-flavor drink. Niteworks is formulated and based on the research of a Nobel Laureate Louis Ignarro.
Niteworks ingredients trigger the production of Nitric Oxide, an important biological messenger that creates a cascade of benefits which can improve the flow of blood to all organs while improving the circulatory and immune-system functions. Herbalife Niteworks is meant to be taken at night, when your body’s Nitric Oxide production is naturally at its lowest.*
Usage: Two scoops (two teaspoons or about 10 grams) in 8 oz. of cold water. May also be mixed with sparkling water or juice. Drink at night or before bedtime.

Herbalife Niteworks Q&A
Why is Nitric-Oxide important to my health? The circulation of blood via arteries delivers oxygen and nutrients to every cell throughout your body, allowing optimum function, including repair and replication. It is understood through the work of many scientists, including Dr. Ignarro, that Nitric-Oxide production is a key component of assuring normal circulatory function and that the production of Nitric Oxide declines with age. By supplying the body with our proprietary Niteworks blend of amino acids, it can stimulate the production of Nitric Oxide, which can help keep blood vessels toned and flexible.
Why do I take Herbalife Niteworks at night? Nitric-Oxide production declines at night. With supplementation of a potent amount of L-Arginine and L-Citrulline from Niteworks, your body can boost its natural production of Nitric Oxide. With better circulation, your body’s natural processes may be enhanced.
What if I forget to take it at night? Can I take it more than once? You can take Niteworks at anytime, although with Lemon Balm’s restful qualities, optimally you will want to take it at night. We recommend that you take it only once per day. Additionally, during the day you are getting Nitric Oxide production from exercise and diet.
Does Niteworks have any special restrictions for use? Yes. Niteworks is not recommended for use by children, pregnant or lactating women and people with high blood pressure or cardiovascular disease. It is advisable for individuals with high blood pressure or cardiovascular disease to consult a physician before using this product.
What is the general news media saying about Herbalife Niteworks? The Washington Post published a news article titled “Nitric Oxide Now — Ask Me How“.
Niteworks Nitric-Oxide benefits: Through vascular nutrition, you can increase the production of Nitric Oxide, which “exercises” or expands your vessels, increasing their youthful elasticity. In addition, Nitric Oxide triggered by Niteworks is an important biological messenger that causes a cascade of benefits at the cellular level, which can improve circulatory, immune and nervous-system function. Nitric Oxide influences the functioning of virtually every organ in the body, including the lungs, liver, kidneys, stomach, brain and, of course, the heart.
Nutrition that counts: Exercise and certain foods promote the production of Nitric-Oxide in your body. Niteworks is designed for nighttime consumption when your body is producing the least amount of Nitric Oxide from food and exercise. However, Niteworks can also be used during the day. Regardless, it would be difficult to ingest the same amount of L-Arginine from foods as your body gets from this product.
Key Niteworks Ingredients:
L-Arginine: A naturally occurring amino acid found in food proteins that the body uses to make Nitric Oxide. It’s difficult to consume enough L-Arginine through food to get the same Nitric-Oxide boost without Niteworks.
L-Citrulline: An amino acid in melons that stimulates the body to produce more L-Arginine, which in turn produces more Nitric Oxide.
D-Alpha Tocopherol (natural Vitamin E): This preeminent fat soluble antioxidant in Niteworks can penetrate the cell membrane to neutralize free radicals and promote cell health. Vitamin E supports the activity of Nitric Oxide and improves endothelium (vessel lining) health.
Ascorbic Acid (Vitamin C): A water-soluble vitamin. Studies suggest that the combination of vitamin C, vitamin E and L-Arginine work to enhance Nitric-Oxide production.
Alpha Lipoic Acid: A co-factor in vital energy-producing reactions in the body. Assists in dilation or expansion of vessels. Also enhances antioxidant activity. Helps protect Nitric Oxide in the body.
Folic Acid: For protection of the vascular system.
Calcium Folinate: Source of folinic acid.
Lemon Balm: Perennial herb in the mint family with a history dating back 2,000 years. Helps provide a calming feeling, so you can sleep better and can awaken feeling rejuvenated.
