What’s the best time to take greens powder?

Greens powder fits easily into a daily routine, but meals, workouts, and fasting windows can make the timing less clear. Here, we break down the best time to take greens powder so it fits the way you eat, train, and fast.

Understanding greens powder

AG1 is a daily Foundational Nutrition supplement that supports whole-body health.* AG1 complements a healthy diet and doesn't replace whole foods. While only 12.3% of US adults met fruit intake recommendations in 2019, and 10.0% met vegetable intake recommendations,¹ AG1 is designed to support your nutrition, not substitute for eating fruits and vegetables. A greens powder can be taken at any time of day, though we recommend first thing in the morning.²

Best time of day to take greens powder

Morning is often the best time of day to take greens supplement powders, but the best time of day is the one you'll repeat tomorrow and the day after. The best time is whichever slot works for you, whether that's before breakfast, mid-morning, or when you get home.

A morning habit gives you a baseline of nutrients and a routine that's easy to remember, which makes determining the best time to take super greens powder more about a pattern you can repeat.² As with any nutrition program, consistency is key.²

Should you take greens powder with food or on an empty stomach?

We recommend taking AG1 Next Gen on an empty stomach, ideally before breakfast, and mixing it with just water. If that doesn't fit your routine, taking AG1 later in the day still beats skipping it!

Can you take greens powder at night on an empty stomach?

Yes, you can take greens powder at night on an empty stomach. We recommend mornings, but an evening habit you'll keep beats a morning habit you'll skip.

Is it better to take greens powder before or after a meal?

Before a meal is better, since we recommend taking our greens powder on an empty stomach. Many people make it the first step of the morning, before breakfast or coffee.

Should you take greens powder before or after a workout?

There's no required workout window, so choose the time you'll repeat. AG1 is NSF Certified for Sport®, which means it's third-party tested for banned substances.⁴

Does taking greens powder with food affect how well it works?

Some foods can help improve the absorption of certain nutrients. Vitamin E is fat-soluble, and in one study of healthy adults, more vitamin E was absorbed after a higher-fat meal than after a low-fat meal or plain water.³ If you blend greens powder into a smoothie or have it with a meal, adding healthy fats such as avocado, seeds, or nut butter helps your body absorb fat-soluble vitamins.²

Factors to consider for timing

Your schedule, meals, and fasting approach may shape your timing. Think about when you eat your first meal, when you train, and which time slot feels easiest to repeat. If you prefer a smoothie, combine it with a healthy fat so you get the absorption benefit described above.²

Can you take greens powder while fasting? Does greens powder break a fast?

One serving of AG1 Next Gen has 40 calories.⁴ A strict fast that excludes all calories would treat it as eating, while a plan built around a daily eating window may treat the timing differently.

Since the term ‘intermittent fasting’ covers several approaches, including alternate-day fasting, 5:2 fasting, and daily time-restricted eating,⁵ greens powder may or may not “count” depending on which approach you follow and why you're fasting. If you fast and have questions about fitting a supplement into your plan, ask your healthcare provider.

Personalizing your greens powder routine

Build your routine around three questions: when do you eat, when do you train, and when will you remember? Start with the answer to the last question, because the best time is the one you'll repeat day after day.

AG1 Next Gen includes B vitamins: B1, B2, B3, B5, B6, Biotin (B7), Folate ( B9), and B12—cofactors that help your body unlock energy from the food you eat—alongside 75+ vitamins, minerals, and whole-food-sourced ingredients, including beetroot, acerola cherry, papaya, pineapple, and matcha.* AG1 Next Gen isn't recommended for pregnant women or anyone under 18, and a healthcare provider can help you decide whether a supplement fits your plan.
