Why take a greens powder?

According to the Dietary Guidelines for Americans, adults should consume 2 cups of fruit and 2.5 cups of vegetables daily (based on a 2000 calorie diet, which isn’t appropriate for all people).1 Greens and green leafy vegetables are an important component of those recommendations.

It’s no secret that whole fruits and vegetables are a vital part of a well-balanced diet, yet only 12% of adults meet fruit recommendations, and just 10% of adults meet vegetable recommendations.2 Maybe it’s a matter of taste preferences, or perhaps life gets so busy that we just overlook adding some color to our plates. Regardless of the reason, many of us are missing out on our recommended greens, fruit and vegetable intake like leafy greens.

While dietitians value the importance of meeting your needs through whole foods, we also like to keep it real. Sure, eating a variety of fresh fruits and vegetables each day provides you with a plethora of nutrients and high-quality dietary fiber. Still, we’d be setting pretty steep expectations if we said you have to meet 100% of your needs through whole foods alone every single day. Enter: greens powders.

What are greens powders supplements good for?

Consumption of green foods such as kale, collard greens, bok choy, and spirulina (you can read more about the benefits of spirulina), among many others, has been linked to a reduced risk of colorectal cancer, heart disease, and type II diabetes.3,4,5 Greens are rich in antioxidants, essential vitamins, minerals, and fiber (fiber is very important to gut health), but if we fall short of our recommended intake, we’re missing out on all their impressive benefits.6

Taking a greens powder can supplement the nutrients we’re missing in our diet. Consumer Lab’s 2022 product review shows that greens and whole food powders contain multiple nutrients, including carotenoids, antioxidants, amino acids, enzymes, nucleic acids, fiber, vitamins, and minerals.7 These essential nutrients are critical to many biological functions, including disease protection, energy production, and digestion support, gut health and digestive health.

What is the best organic greens powder?

Consumer Labs tested 20 greens powder products for levels of arsenic, cadmium, lead, and mercury, as well as pesticides and microbes. Of the 20 products tested, 16 met their quality criteria. Several greens powders, four, failed to meet Consumer Labs’ standards either contained significant levels of heavy metals or failed the disintegration test.

We compared Consumer Labs’ extensive research against our standards for our Organic Authority Approved Seal to narrow down the list and provide you with three of the best organic greens powders on the market.

Advice From a Registered Dietitian

Although greens powders are concentrated versions of fruits and vegetables like leafy green vegetables, they should not replace the colorful portions of your meals. Greens powder can be a beneficial supplement in your routine, but it should not replace whole foods. (Read: eat your salad!)

Aim to meet your nutrition needs through whole food sources first, and if you need a little extra support, go for the greens. If you’re crunched for time, mix greens powders into your morning smoothie is a great way to pack your on-the-go meal with quality nutrition. You can even use the supplement to give your baked goods a boost of vitamins and minerals.

Also, it’s extremely important to discuss new supplements with your doctor or registered dietitian. Most important to note, the vitamin content in greens powders may affect certain medications. 

Frequently Asked Questions

Is taking a greens powder supplement worth it?

Adding a greens supplement to your wellness routine can provide many health benefits, but it’s important to remember that your nutrition needs are unique to you. Talk to your doctor or registered dietitian to determine the impact of greens powders on your health.

In general, some potential health benefits of greens powder can include:

Immune System Support

Greens powders are packed with vitamins and minerals that support a healthy immune system. For example, many greens supplements contain selenium which can help your immune system fight infection.14

Chronic Disease Prevention

Specific vitamins have been shown to have antioxidant properties. Vitamins C and K, found in many greens powders, can help prevent cell damage from free radicals.10,6 If left unchecked, this cell damage can lead to chronic diseases such as heart disease and diabetes.15,16

The health benefits of chlorella, a blue-green algae that’s found in many greens powders, has shown beneficial effects against chronic diseases such as hypertension, hyperlipidemia, and diabetes.11 You may notice a decrease in your triglycerides and total cholesterol if you include greens powders in your routine.

Eye and Cognitive Health

Nutrients found in green leafy vegetables have been shown to play a significant role in eye health, especially for age-related eye disease.12 Furthermore, research has shown that just one serving of green leafy vegetables daily can help slow cognitive decline with aging.13

Can greens powders help with weight loss?

Greens powders can help promote weight loss, but not in a magical way by any means. Instead, greens powders can help support a healthy digestive system, which has been shown to influence weight.

Recent research examined the relationship between the gut microbiome (gut health) and body weight and found that using dietary agents (prebiotics/probiotics/synbiotics) reduced body mass index (BMI).8

Some greens powder supplements include prebiotics, probiotics and digestive enzymes in their ingredients, helping to support a healthy gut. Add that to their vitamin and fiber content, and you have a recipe for gut health success.

Do greens powders help with IBS?

Speaking of gut health, some companies claim that greens powder can help symptoms of irritable bowel syndrome (IBS). In reality, many greens powders contain fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs), which can worsen IBS symptoms.9

Some people with IBS even have difficulty with prebiotics, probiotics and digestive enzymes. If you have digestive problems, it’s important to read the ingredients thoroughly and discuss any potential contraindications with your doctor.

Can greens powders supplements alkalize my system?

Many companies claim that greens powders have an alkalizing effect on the body by adjusting your blood’s pH level. However, there is no evidence that supports the idea that an acid-producing diet leads to chronic illness, or that food in general can easily change the pH of your blood.10

In fact, the human body tightly regulates the pH of its blood between 7.35 and 7.45 using a complex system of checks and balances. The foods you consume will briefly increase or decrease the pH of your urine or saliva but will not affect the pH of your blood.7
