Greens First Review - Does This Supplement Work? Is the lack of an active weight loss ingredient a deal breaker?

Editor's Review: 4.2 / 5.0
Greens First Review

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.

EDITOR'S TIP: Combine Greens First with a proven fat burner such as Leptigen for better results.

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.

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 is Leptigen. 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 Leptigen want to encourage new customers to try the product with a special trial offer, which is a great sign.

Consumers everywhere perform research to find out what diet plans will work best for them in order to look and feel better for the Spring and Summer seasons. Greens First Meal offers a 12-week Challenge and gives itself credit for being able to help people lose up to 15 lbs in a 12 week time period. The Weight Loss to Wellness Kit includes a 30-day supply of Greens First, 30-day supply of Greens First Meal, Weight Loss to Wellness Book, and a snap-top shaker cup, and is priced at $107.93.

The challenge consists of using both Greens First and Greens First Meal in combination with proper diet and frequent exercise. Greens First are meal supplements that should be consumed twice a day. To lose weight you would substitute breakfast and either lunch or dinner with these nutritious shakes. If you are using Greens First for wellness and maintenance as opposed to weight loss you should only take one scoop of Greens First when you wake up, and drink one shake a day instead of two. The website stress the importance of drinking 6 oz of water after every Greens First Meal as it activates the natural ingredients and produces the best results.

List of Ingredients

The Greens First Meal Supplement includes the nutritional value of 10 servings of fruits and vegetables, important vitamins, an antioxidant and energy blend of various fruit powders, and only contains 45 calories per serving. Additional ingredients include pro-biotics and enzymes for good digestive health, and natural anti-inflammatory agents.

Product Features

Greens First’s official website claims the product will support immune function and increase resistance to infection, improve mental perception, strengthen memory, and prevent vision loss and blindness associated with getting older. This dietary supplement also mentioned that it will help remove toxins from the body system, and help you look and feel younger.

    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.

    I have personally found greens first to be the best product of its kind on the market. I have been trained as a nutritional therapist and have tried many products through the last 7 plus years. I don’t blame anyone who puts out a product like this to not have a money back guarantee. What a can of worms that would be to them. As far as the disclaimer goes and the FDA not approving…WHOCK? Everybody needs that stupid disclaimer these days in a sue-crazy society ! The FDA is so busy being in the pocket of corporate drug pushers in the name of medicine *&%$?! it is usually a better product that doesn’t carry the almighty FDA approval !!!

    I am in the restaurant business, and on my feet for 8-10 hours a day. With in the last tear I have discovered the I have RA and it has created a lot of fatigue and pain in my legs and joints over the last 8 months. A Doctor recommended Greens First to my Father that was going through Cancer treatments and that is how I found out about the product and the importance of our bodies PH. My Dad had that Grey Pasty look, and a month or so later after using Greens First looked fantastic. His energy level was up, his skin looked great and he felt better in General. I am now on my 2nd month and my Pain a swilling is gone, but I still have a lot of stiffness. All as I can say is I can hardly wait to see how I feel in another month. And yes my energy level is up and I have lost perhaps 6 lbs. I believe the Dutch Chocolate Boost will be my next purchase to see if it will help get rid of the stiffness and get back some real strength to my legs, Thank You Greens First. Oh, by the way my Mother had RA and she died at 64, and it was due to the medications that she was so easily able to get through our health system. That is why I know this problem needs to be addressed by diet and not pain killers that destroy our bodies.

    Stevia is an ingredient in Greens First. Is it safe for humans to consume? Not a food some of us would eat

    I’ve recently been started on the blood thinner coumadin. Is it alright to continue to drink Greens First? I don’t see how much vit K is in it per the label.

    HI am 25 lbs overweight, I am not comfortable with that and I also have High Blood Pressure. If I try this what is my guarantee that I will lose the extra 25 lbs. weight and lower my blood pressure to normal. I want to stop taking my prescription medication which is Micardis Plus. Can this help me? Do you have money back guarantee?
    please reply so I can place my order soon. thank you.



    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.
