What Are the Benefits of Green Powders (If Any)?

OK, so. I have a guilty pleasure: watching vlogs.

Y’know, “influencers” or even random people documenting their daily lives — some might use the word “vapid” to describe the content (my brother does 🥹), but I don’t know. There’s just something about seeing someone live their life.

*ahem* Right. There’s a point to this article. And it’s this: recently, I’ve started noticing the same formulaic introductions in, like, 95% of the vlogs. It goes a little like this:

“Good morning! I’m starting my day off with [INSERT GREEN POWDERS BRAND]. Since I did, I’ve just felt so energized, and my bloating issues have gotten soOOoo much better!”

I mean. I wouldn’t call myself easily influenced, but my curiosity was piqued by the 10th video (yes, I know, I might be watching way too many vlogs). Which explains this article.

What are green powders?

Before diving into the most important question weighing on our minds (i.e., are the supposed benefits of green powders supported by research?), let’s first cover what green powders are.

Green powders are a blend of dehydrated fruits, vegetables, herbs, and sometimes pre-and probiotics, alongside other nutrients.

Depending on the brand and company, green powders can contain anywhere from 25 to 40 different ingredients — spirulina, apple, beet, broccoli, carrot, spinach, pineapple, and rose hips.

They are generally designed to be mixed with water or another liquid.

The main selling point of green powders? They’re meant to help people easily reach their recommended daily vegetable and fruit intake in just 1 serving.

FYI, according to the CDC, only about 11% of American adults eat the recommended amount of fruits and vegetables … so if green powders truly count toward a person’s daily vegetable and fruit intake, they’ll be very helpful.

How Many Fruits and Vegetables a Day (Fewer Than You Think!)
“Eat your fruits and vegetables!” Yeah, OK but how many fruits and vegetables a day, exactly? And how does it help our health? Find answers here.

But do they actually? Spoiler alert: they don’t. More below.

A skeptical look at the benefits of green powders 🧐

Let’s bust through the supposed benefits of green powders, one at a time:

🥗
Counts towards your daily fruit and vegetable intake?

Green powders are not a replacement for the intake of fruits and vegetables because, during processing, important nutritional content like fiber and certain micronutrients are lost.
🤰
Helps with healthy digestion?

Many green powders contain digestive enzymes. Athletic Greens’ formulation, for example, includes bromelain, a plant-based digestive enzyme from pineapple that breaks down protein.

But here’s the thing:

1️⃣ Unlike pharmaceutical or prescriptive-grade digestive enzymes, you can never be sure that supplemental ones 1) contain an efficacious dose, 2) can survive the stomach’s harsh acidic environment, and 3) will help with your specific digestive distress (what if your trouble is with carbohydrates, instead of protein?).

2️⃣ Besides, if you’re healthy, your body should produce sufficient digestive enzyme levels to break down foods (even if it’s a heavy meal).
Supports gut health?

One of the best ways to support your gut health is by eating a varied diet of high-fiber foods (reminder: green powders contain very little fiber) — from legumes and whole grains to vegetables and nuts.

Downsides of green powders

OK, so there’s that for the benefits of green powders.

But what about seeing them as a nice little treat in the morning? Welllll. Here’s what you need to know:

  1. They are very expensive for what they are: A single serving of Athletic Greens powder costs $2.63, and it doesn’t even count toward your vegetable and fruit intake 🥴. For a top-up of $0.36, you could get 1.36 kg (3 lb.) of fresh mandarins from Aldi. IDK about you, but the choice seems clear here.
  2. You can overdo it on certain nutrients: For example, excess amounts of niacin (vitamin B3) may cause skin flushing and dizziness.
  3. Risk of toxicity: In 2016, Consumer Labs found trace amounts of lead and arsenic in several green powders. Note that studies show even low-level exposure to contaminant metals contributes to the development of cardiovascular disease, especially heart attacks and strokes.
  4. Potential interference with medications: Common “superfoods” found in green powders, including chlorella and spirulina, provide high vitamin K levels, which help blood clot. This can be dangerous for those taking blood-thinning medications.

Are green powders a waste of money?

Given everything we’ve discussed, the answer seems clear: yes.

But let’s not jump to conclusions.

There are some instances in which green powders make sense. Case in point: if you’re traveling and do not have access to fresh fruits and vegetables, green powders will be your next best alternative.

Now, if you are interested in trying out green powders, here are a few tips:

🧑‍⚕️
Speak with your healthcare provider first: Before you start taking green powders (or any dietary supplement, for that matter), consult your healthcare professional. This can help determine if your allergies or medications — if any —may interact negatively with green powders.
👀
Look for products with third-party certification: Third-party testing ensures ingredients' purity, potency, and identity (remember the deleterious health effects of heavy metals?). Ideally, look for stamps of approval from ConsumerLab.com, NSF International, or the U.S. Pharmacopeia.
🔍
Read the label and ingredients: Some powders may contain added sugar, artificial additives, caffeine, or other ingredients you may not want in your green powder.

How else can you support your health?

You know what has a larger body of evidence supporting its health benefits, from mental clarity to gut health? Actual fruits and vegetables, yes (oOOOooh, burn!)

But also exercise. Cardio and strength training.
