What Happens When You Start Taking Greens Powder?

When you consume greens powder drinks, your digestive system breaks down the powder just like other foods. The nutrients in the greens powder are absorbed by the digestive tract and used to fuel the body.

The nutritional content can vary, but the best green powder supplements contain a wealth of important vitamins and nutrients. One serving of greens powder, like Rewind Greens powder mixes, provides:

  • Essential vitamins like A and C 
  • Minerals like calcium, iron, and potassium 
  • Protein 
  • B vitamins 
  • Probiotics for digestive support 

When you start taking greens powder, you are essentially providing a better-rounded level of nutrition. Therefore, most people start to notice a difference in how they feel, their energy levels, or even their appetite levels.

Does Greens Powder Have Side Effects?

In general, most people do not experience side effects from super greens powders, especially if they select a trustworthy brand. Nevertheless, there are a few side effects that could occur. These side effects are simply due to the change in your diet or perhaps sensitivities to certain ingredients. Take a closer look at all you need to know below. 

Digestive Discomfort 

One of the most common issues people report when taking super greens powder is digestive discomfort. This discomfort may include side effects like: 

  • Bloating 
  • Gas 
  • Diarrhea
  • Nausea 
  • Constipation 

Most of the digestive symptoms associated with greens powders can be associated with the ingredients. And symptoms do vary by person. For example, some individuals experience gas and bloating when they consume cruciferous vegetables like broccoli or leafy greens like kale. 

Issues with constipation, diarrhea, or nausea may be related to sensitivity to certain food-based ingredients as well. For instance, a higher intake of fiber—which is natural in greens powders—could be associated with constipation. Likewise, some individuals may be sensitive to probiotics, which could lead to nausea or diarrhea. 

Medication Interactions 

While rare, medication interactions with the ingredients in greens powder could lead to side effects. The combination of many food-based ingredients can elevate the volume of nutrients you consume at once. In most regards, this is a good thing. However, there can be some potential for ill effects for specific individuals due to medication interactions. 

For example, some individuals have to monitor their vitamin K intake because it can interact with certain medications. Green powders can have higher levels of vitamin K. Medications that can be influenced by vitamin K include weight-loss medication, antibiotics, anticoagulants (blood thinners), and cholesterol medications.

Allergic Reactions 

Allergic reactions to ingredients in greens powders cannot be ruled out. Oftentimes, individuals that experience side effects of greens powders are actually allergic to one of the ingredients. For example, if you are allergic to green tea or wheatgrass, you could experience effects related to an allergic reaction. 

What to Avoid in Green Powder to Reduce Side Effects 

Side effects are possible for some people with even the best super greens. However, choosing the best product makes a difference. Therefore, there are key factors to look for in products to lower the chances that you face issues with digestion or otherwise. 

Avoid Low-Quality Ingredients and Sketchy Manufacturers  

Top-quality super greens powders are made with quality ingredients. They will not include any fillers, additives, or artificial sweeteners. The ingredient list will be clearly available on the website and product label.

Additionally, well-made products tend to have additional ingredients included that can support digestion. Probiotics or digestive enzymes like bromelain are good examples. Low-quality brands don't always have these agents because they heighten manufacturing costs. 

Finally, look for information about the manufacturer and its quality-control processes. For instance, Rewind Greens are made in a GMP-rated facility that is FDA-approved and located in the U.S. Further, each batch of super greens is tested by a third-party lab for contaminants like heavy metals. 

Avoid Consuming Super Greens Made with Sugar Alcohol  

Sugar alcohol shows up in some low-quality super greens drink mixes due to the presence of artificial sweeteners. Well-made super greens powders will not contain sugar alcohol because this ingredient can be a major culprit behind digestive upset. 

It is important to note, super greens that have been carefully formulated in a way that they taste good will not need artificial sweeteners. Instead, manufacturers rely on the flavors of the food-based ingredients. The natural sweetness of these ingredients creates an enjoyable mix. 

Avoid Food Ingredients That Could Cause a Reaction 

Quite a few types of food are highly associated with adverse reactions and food sensitivities. A few examples are dairy, nuts, eggs, soy, and gluten. If you are prone to food sensitivities, pay close attention to the ingredients in any super greens product. 

Some super greens contain a lot of gluten, for example, because it is used in wheat-based fillers. The best super greens supplements are created in a way that is mindful of food sensitivities. Rewind Greens are made with none of the aforementioned foods that are considered risky when it comes to food sensitivities. 

How to Deal with Greens Powder Side Effects 

Side effects of super greens powder are not all that common. However, if you do experience side effects, it is important to know what you can or should do. Take a closer look at what to do if you experience some of the most common side effects. 

How to Handle Super Greens Upset Stomach 

If the super greens product you are taking is causing nausea, gurgling, or even diarrhea, evaluate the ingredients first. Make sure you don't see artificial sweeteners on the label or food ingredients that could cause sensitivities like soy or dairy.

If you are consuming a high-quality product like Rewind, you may simply need to adjust how much you are consuming. For example, instead of using a full scoop of powder, use only a half scoop. It can also be helpful to try consuming the drink on an empty stomach. 

In some cases, people have issues with an upset stomach simply because their bodies are not accustomed to the new foods. Therefore, it is completely possible to experience some level of digestive upset during the first few days of consumption. However, these symptoms can subside soon after with continued use. 

How to Handle Super Greens Bloating and Gas 

Bloating and gas are often caused by the food ingredients in the mix. As noted earlier, leafy green vegetables like kale or spinach can be associated with gas. Likewise, cruciferous vegetables like broccoli can cause gas. 

Picking a product with digestive enzymes can help deter issues if you experience bloating or gas. However, it is also a good idea to try adjusting the timing of consumption. For example, if you have your drink at night, try switching to morning when you are going to be most active. The digestive process can be faster earlier in the day. 

You can also try adjusting your super greens dose if problems persist with gas and bloating. Also, be sure to consume your greens on an empty stomach and wait a few hours before eating to make sure the issue is coming from the greens and not something else in your diet. 

How to Handle a Suspected Allergic Reaction 

Food allergies can be characterized by everything from gastrointestinal to respiratory reactions. Therefore, watch for symptoms like: 

  • Rashes on the skin 
  • Upset stomach 
  • Sore throat or difficulty breathing 
  • Facial swelling 

If you experience any of these symptoms, discontinue your use of super greens and consult a physician. Severe allergic reactions may require immediate attention. 

Super Greens Powder Side Effects FAQs 

Are there more side effects with green powder vs multivitamin products?

The side effects you could experience will vary depending on the ingredients in each product. Multivitamins tend to only contain isolated vitamins and minerals, while greens powder contains both vitamins/minerals and plant compounds. Therefore, it may be more likely to experience side effects with consuming greens powders, but not always.  

Is it true that some people take greens powder for bloating?

While gas and/or bloating may be a potential side effect of greens powder drink mixes, some people do take greens powders for digestion support. Particularly, greens products that contain probiotics are thought to deter issues with bloating and constipation. 

Well-formulated greens powders also contain digestive enzymes that can aid in digestion and reduce bloat. A few could include lipase, amylase, and lipase. These enzymes do their job by helping the digestive tract break down proteins, fats, and carbs. However, they may also support the absorption of nutrients.

Are there any benefits of drinking greens in the morning to avoid side effects?

There can be quite a few benefits to taking your greens powder in the morning. However, doing so is primarily a matter of preference for most people.

Greens drinks usually provide a bit of an energy boost. So, they are a good way to get the day started off on the right foot with enough energy to get you going. Likewise, some say that taking the greens on an empty stomach seems to help the body absorb the nutrients faster. 

One caveat when it comes to the time of day to drink your greens drink is digestion. When you go to sleep at night, the rate of digestion slows. Therefore, if you drink a super greens drink just before bed, you may be more likely to experience digestive discomfort.

Can greens powder make you sick?

Can greens supplement upset your stomach? Yes, even though these side effects can be avoided with a good-quality product. However, a super greens powder should never make you sick unless the product is poor quality or contaminated. 

As long as you choose the best possible super greens supplement, you are not likely to have any issues. Always pay close attention to the shelf life or expiration date of the product and purchase from a brand that conducts quality assurance. 

If a super greens product seems to make you ill, you could be dealing with ingredient sensitivities or allergies. Therefore, it would be best to discontinue use.
