3 min read

Over 57% of U.S. adults reported using a dietary supplement in a single recent month, with many seeking general health benefits. For those incorporating Athletic Greens' products, a common question arises: Can AG1 affect sleep? The answer lies in understanding that AG1 is formulated for morning energy, while the brand's separate product, AGZ, is specifically designed for nighttime rest.

Quick Summary

AG1 is a daily morning supplement for foundational nutrition and energy, not a sleep aid. It contains ingredients like B vitamins to support daytime vitality. The manufacturer created a distinct nighttime product, AGZ, featuring calming ingredients to promote a restful night's sleep. Taking AG1 in the morning and AGZ at night is designed to provide a complete day-and-night health routine.

Key Points

Morning Supplement: AG1 is designed for morning consumption to support energy, immunity, and gut health throughout the day.
Separate Sleep Product: The company offers a separate product, AGZ, which is specifically formulated with calming ingredients for nighttime rest.
Energy-Supporting Ingredients: AG1 contains B-vitamins and other components aimed at boosting energy metabolism, which is why it is recommended for morning use.
Sleep-Specific Formulation: AGZ includes magnesium L-threonate, ashwagandha, and L-theanine to promote relaxation and improve sleep quality.
Different Goals: AG1 is not a sleep aid; its purpose is foundational nutrition, while AGZ is tailored for those seeking sleep support.
Day-and-Night Strategy: For comprehensive support, users can incorporate AG1 into their morning routine and AGZ into their evening ritual.
Individual Responses: While most people experience no sleep issues with AG1, initial side effects like digestive upset could temporarily disrupt sleep for some.

AG1: A Morning Ritual for Daytime Energy

Athletic Greens’ AG1 is a foundational nutrition drink intended for daily morning consumption. Its blend of over 75 vitamins, minerals, and whole-food sourced ingredients supports various health aspects, including energy production, immune function, and gut health throughout the day. AG1 is designed to support daily vitality rather than aid sleep. While many users report feeling more energized, taking AG1 close to bedtime is not recommended and could potentially disrupt sleep.

How AG1's Ingredients Influence Your Day (Not Your Night)

AG1 contains ingredients focused on providing energy and managing stress during the day. Key components include B vitamins like B6, B12, and biotin, which support energy metabolism. Adaptogens such as Rhodiola are included to help the body manage stress. While better stress management can indirectly benefit sleep, the adaptogens in AG1 are for daytime resilience. Some individuals may experience temporary digestive upset from AG1, which could potentially interfere with sleep, but this is not a direct sleep-related effect of the product.

Introducing AGZ: The Complementary Nighttime Formula

The makers of AG1 developed AGZ as a separate product specifically for nighttime use, recognizing the importance of sleep. AGZ is a melatonin-free formula with ingredients chosen to support restful sleep. It's designed to be a nighttime ritual that complements the morning use of AG1.

Key Ingredients in AGZ for Restful Sleep

AGZ's ingredients are selected for their calming properties to help prepare the body for rest. Unlike AG1, AGZ is formulated to assist with relaxation. Its key ingredients include Magtein® Magnesium L-Threonate, shown to improve sleep quality and cognitive function. Ashwagandha, an adaptogen, helps manage stress and supports relaxation and sleep quality. L-Theanine promotes a calming effect, while Valerian and Saffron are known for supporting relaxation and sleep.

AG1 vs. AGZ: A Comparative Analysis

Here is a comparison of AG1 and AGZ to highlight their distinct roles:


Feature	AG1 (Greens Powder)	AGZ (Nighttime Formula)
Timing	Recommended for the morning on an empty stomach for optimal absorption.	Recommended nightly before bed to support winding down and restful sleep.
Primary Goal	Provides foundational nutrition and supports energy, immunity, and gut health throughout the day.	Specifically designed to aid in evening relaxation, restful sleep, and waking up refreshed.
Key Ingredients (Energy/Function)	B-vitamins, stress adaptogens, probiotics, whole-food sourced nutrients, enzymes.	Calming herbs, stress adaptogens, minerals (Magtein® magnesium L-threonate), and other targeted sleep nutrients.
Sleep-Specific Ingredients	None explicitly for sleep; general health benefits may indirectly support better sleep habits.	Ashwagandha, L-Theanine, Valerian, Saffron, Magtein® magnesium L-threonate.

Best Practices for a Complete Day-and-Night Routine

For comprehensive health support, including both daytime energy and nighttime recovery, it's recommended to use both products as intended. Start your day with AG1 to support energy and fill nutritional gaps. In the evening, take AGZ as part of your nighttime routine to promote relaxation and prepare for sleep. As with any supplement, consult a healthcare provider before starting, especially if you have existing conditions or take other medications.

Conclusion: Optimizing Your Wellness with a Day-and-Night Strategy

In conclusion, AG1 is not intended to affect sleep; it is designed for daytime energy and foundational nutrition. The company's separate product, AGZ, provides targeted sleep support with calming ingredients. By using AG1 in the morning and AGZ at night, consumers can support their health throughout the day and night.
