According to AG1's own clinical research, a significant percentage of users report increased energy levels, with 85% of participants in one study feeling more energized after one month. This energy-boosting effect is a primary consideration when evaluating whether you should drink AG1 at night, as its formulation is best suited for starting your day rather than ending it.

Quick Summary

The question of consuming AG1 before bed is common, but its formula contains B-vitamins and energizing adaptogens that are counterproductive for rest. For optimal absorption and energy benefits, morning consumption is advised, while the company offers a separate product, AGZ, for nighttime use.

Key Points

Morning is Best: AG1 is primarily an energy-boosting supplement best consumed in the morning on an empty stomach for optimal absorption.
Energizing Ingredients: The high concentration of B-vitamins and adaptogens like rhodiola in AG1 can interfere with sleep patterns if taken at night.
AGZ for Nighttime: Athletic Greens offers a separate product called AGZ, which is specifically formulated with relaxing ingredients like magnesium and saffron to support restful sleep.
Consistency Matters: While morning is ideal, consistency is most important. Find a time that works for your routine, but be mindful of potential sleep disruption if taking it in the evening.
Consider the Alternatives: If you seek a supplement specifically for nighttime wellness, AGZ or other sleep-focused alternatives are more appropriate than AG1.
Not a Replacement for Food: AG1 should supplement a balanced diet, not replace whole fruits and vegetables, which provide many nutrients for overall health.

Why Morning is the Recommended Time for AG1

Athletic Greens officially recommends taking AG1 first thing in the morning on an empty stomach for optimal absorption and to capitalize on its energy-supporting benefits. While consistency is the most important factor in a supplement routine, the blend of active ingredients in AG1 is specifically formulated to help you start your day feeling your best. The body is primed in the morning to process nutrients effectively, especially on an empty stomach, which allows for maximum utilization of the broad spectrum of vitamins, minerals, probiotics, and superfoods contained in each scoop.

AG1's Energizing Ingredients and Their Effect on Sleep

The primary reason against consuming AG1 in the evening is its concentration of energizing and stress-modulating ingredients that can interfere with the body's natural wind-down process before sleep. The formula is packed with a high dose of B-complex vitamins, which play a crucial role in converting food into energy.

High Potency B-Vitamins: AG1 contains exceptionally high percentages of the daily value for various B-vitamins, including B12 (917% DV) and biotin (1,100% DV). B-vitamins are essential for metabolism and energy production, and consuming them late in the day can over-stimulate your system, making it difficult to fall asleep.
Adaptogens: The formula includes adaptogenic herbs such as ashwagandha and rhodiola. While ashwagandha can help manage stress, rhodiola is noted for supporting mental clarity and focus. For most people, these are effects best utilized during the daytime to manage daily stressors and maintain concentration, not for winding down at night.
Matcha and Cocoa Extracts: AG1 contains trace amounts of caffeine from matcha green tea leaf powder and cocoa extract. Though the amount is small, for individuals sensitive to stimulants, even a minimal dose can disrupt sleep patterns, especially when taken in the hours leading up to bedtime.

The Dedicated Nighttime Alternative: AGZ

Recognizing the need for a separate product tailored for rest, Athletic Greens developed AGZ as a nighttime complement to AG1. This product is specifically formulated to support restful, restorative sleep, without melatonin and without causing morning grogginess. Its ingredients are chosen for their calming properties, directly contrasting the energizing components of AG1.

Key ingredients in AGZ include:

Magtein® magnesium L-threonate: A clinically tested form of magnesium shown to improve sleep quality and support cognitive function.
Saffron: Demonstrated in clinical trials to enhance sleep quality and support a healthy mood.
Ashwagandha: An adaptogenic herb used to help the body manage stress and support relaxation.
L-Theanine: An amino acid with a calming effect on the nervous system.

For those seeking comprehensive daily health support, using both products as intended offers a balanced approach. Below is a comparison table to help illustrate the difference and guide your routine.

The Takeaway: Prioritize Your Body's Natural Rhythm

Ultimately, deciding when to take a supplement depends on its intended effect and your body's natural rhythms. AG1 is formulated to support energy and vitality, making it an excellent start to the day. The presence of high-dose B-vitamins and stimulating adaptogens can be counterproductive to a good night's sleep if taken in the evening. For those who want to integrate a supplement into their nighttime routine, AGZ is the targeted solution from the same brand, specifically designed with relaxing and sleep-supporting ingredients.

While personal experience can vary, and some people may not notice an effect, most will benefit from adhering to the morning recommendation for AG1. This approach aligns with the product's purpose and allows your body to get the right support at the right time. For optimal results, use AG1 in the morning and AGZ in the evening, as recommended by the company. Always consult a healthcare professional before adding any new supplement to your routine, especially if you have existing health conditions or take other medications.

Conclusion

In conclusion, while AG1 can be taken at any time, its formulation, rich in B-vitamins and energy-supporting compounds, makes it far better suited for morning consumption. Taking it at night could potentially interfere with sleep for many individuals due to these stimulating ingredients. For a balanced approach that supports both daily energy and nightly rest, consider using AG1 in the morning and its dedicated nighttime counterpart, AGZ, in the evening, following the manufacturer's recommendations.
