Greens First Review - Does This Supplement Work?


We are big fans of all natural products. We also love to see people improving their overall health with the use of fruits and vegetables, so we were doubly excited to begin researching the Greens First Plan. We looked at the information provided by the company’s website, as well as expert reviews to formulate our opinion.

What You Need to Know

Greens First is a 12 week program that claims to help individuals lose as much as 15 pounds in the 12 week challenge period. The Weight Loss to Wellness Kit includes a 30 day supply of Greens First Meals, a 30 day supply of Greens First, a wellness book, and a shaker cup for $107.93. It is important to note that this is only a four week supply, and two more months of products will need to be purchased to complete the 12 week program as intended. This substantially raises the cost from the initial price.

The manufacturer’s claim that in addition to promoting weight loss, the product will also boost the immune system, enhance memory and mental cognition, and reduce the risk of vision impairments commonaly associated with aging, but read on…

How Does it Work?

The program consists of two products, Greens First and Greens First Meal, along with exercise and a proper diet. The Greens First product is a meal replacement that should be taken twice a day, with a full glass of water.

Our research editor had one concern, “The advertised rate of weight loss is not any more substantial than what can be found with moderate diet changes and exercise. Nothing in the promotional materials indicates a reason to add this to such a regimen.”


Specific ingredients are not provided, however, the products include the equivalent of 10 servings of vegetables and fruits, antioxidants, pro-biotics, and enzymes.

The Science

Greens First does not offer any scientific evidence to support that their formula is in any way superior to other meal replacements. While increased consumption of fruits and vegetables is known to help facilitate weight loss and improved health, these are not whole fruits and vegetables.

What Users Are Saying

"”Great taste! I have tried other “Green” drinks and supplements and I don’t end up using them because of the taste. I love the minty light taste. Thank you kindly!”"

"”It’s very sweet and the mint is overpowering. It’s tolerable alone in water but impossible to add to a smoothie (tastes like you’re drinking spearmint gum). Would LOVE to see a non-sweetened version. Otherwise, it’s a great travel aid….tough to get enough plants when I’m on the road, so this will help.”"

"”It was o.k. doesn’t taste very good. But it is supposed to be veggies. Has not given me noticeable energy yet. Just not sure if it is working yet. Maybe too early to tell.”"

The Bottom Line

There are no money back guarantees, and no documentation that supports the claims of the product. While the taste of the meal replacement shakes has overwhelmingly positive reviews, there is little evidence that they are anything more than a tasty meal replacement.

While the program may enhance overall health, those interested in facilitating weight loss may need to look for a product that has been specifically designed to promote weight loss.

One of the best weight loss products we’ve seen this year is Dietspotlight Burn. It’s made with ingredients that are well known for their ability to facilitate weight loss. Our research indicates that not only are the ingredients well tested, but consumer are also pleased with their results.

The makers of Dietspotlight Burn want to encourage new customers to try the product with a special trial offer, which is a great sign.

    • Debbie

      I have a bachelor’s in Nutrition and read labels like crazy Marivic. I have used this drink in the morning before breakfast. I don’t use it for weight loss so to speak. I use it to balance my PH levels and take advantage of all the nutrients it includes. My thought is it won’t make you lose weight. BUT, the nutrients in it, along with a balanced diet AND exercise is going to help you lose weight.

    • Maribel (Editor)

      Hello Marivic. All users are different and can experience different weight-loss results. Please make sure to consult with your physician before starting a new product.

Please respond back at the email address given Thank You. I already use this product but am concerned now what I’ve learned about what some one with Thyroid problems shouldn’t eat a lot of.
    Thank You Carol

  • What is the cause it?
    kscarpella (Verified User)

    I have been using Greens First and vanilla boost for just three days and I have had really bad gas with this product. What could be causing this and will it get better with continued use?

    • Liz Berry

      I imagine it contains a great deal of fiber. Make sure to drink more than 6 ounces of water after using and drink lots of water during the day. Also check to see if the product has psyllium (spelling?) which can cause gas.

    Decaffeinated green tea…..how does this affect the nutritional value of the green tea constituents?
