What Exactly is Soylent?

Soylent is a meal replacement product that has been around since 2014. It combines essential ingredients and compounds that are necessary for daily nutritional requirements and adds some flavor for taste and ease-of-consumption. This results in a powder that is mixed into a drink format that can totally replace any of your meals at any point during the day. 

Soylent can be purchased in drink-ready format or in powdered format to be added to your own liquid at your convenience. Let’s find out how Soylent compares to other supplement drinks.


What’s Inside a Bottle of Soylent?

Soylent drinks all have the same major ingredients with only minor variations depending on the exact flavor that you purchase. These ingredients are:

  • Water
  • Maltodextrin
  • Soy protein isolate- this provides much of the protein in the meal replacement and has a neutral taste. This protein source comes from a plant, so Soylent products are vegan.
  • Canola oil
  • Algal oil- this fat source is free of harmful trans-fats.
  • Rice starch
  • Boat fiber
  • Isomaltulose– this sugar is designed to replace harmful table sugars but still provide the energy your body needs.

The ingredients above contain amounts of fiber, carbohydrates, fat, and protein so that each bottle has enough of the major macromolecules necessary for proper nutrition. A standard Soylent meal replacement bottle is 14 ounces and contains enough drink to replace one full adult meal.

Five Soylent drinks per day give about 2000 calories and 100% of all the daily recommended essential micronutrients needed for healthy living. Each Soylent drink can, therefore, be broken down to have:

  • 400 calories
  • 36 g of carbohydrate
  • 21 g of fat
  • 3 g of fiber
  • 20 g of protein
  • 200 mg of calcium
  • 700 mg of potassium
  • 4 mg of iron
  • 20% of the recommended daily value of all major vitamins and minerals

The flavors are produced by adding things such as cocoa powder, strawberry extract or vanilla extract to make the drinks more palatable for mainstream consumption.

There are also Soylent Café drinks that combine caffeine and L-carnitine, both of which are energy-boosting compounds to give you an awakening effect, similar to that granted by a cup of coffee.

What Does Soylent Do?

Essentially, Soylent replaces one full meal for each drink that you consume. It requires fewer raw materials and less time for preparation than any other traditional, solid-food meal available. When consumed enough, it can even replace all of the meals in a day without requiring additional supplements.

How Can This Benefit You?

Drinking Soylent can provide anyone with a number of great advantages.

  • Save time
  • Save money
  • Ensure that you get the needed amount of micronutrients and vitamins
  • Help with dieting

For many people, Soylent can help them to eat more healthily and achieve a more balanced diet.

Because you won’t be tempted by the taste of food during a meal to eat more, drinking a single bottle of Soylent can help you maintain proper caloric intake without going overboard.

At the same time, Soylent is thick enough to give your stomach a relatively “full” feeling so you aren’t hungry all the time.

Soylent can save money and time for many people. Drinking only Soylent can result in spending less money on food and less time on food preparation depending on your current eating habits. A twelve-pack of Soylent meal replacers costs about the same as a day’s worth of food for many healthy adults.

Side Effects of Soylent

Of course, Soylent contains soy protein isolate as its primary source of protein. This makes Soylent dangerous if you have a soy allergy.

In addition, Soylent is a liquid first and foremost and is thicker than many other drinks typically consumed throughout the day. Some people have reported side effects including bloating, excessive gas, or a reduction in bowel movements. While there is no significant evidence that these side effects are guaranteed, it’s still worth noting that Soylent may affect your digestive system differently than it does others’.

The presence of phytate content may also result in a subpar iron absorption rate. Iron is critical for human survival and some is normally included in the Soylent formula. For a few people, phytate in the drink may result in this iron not being absorbed and may require the consumption of a supplement or an additional food to make up for this fact.

Finally, Soylent has not been tested in the long term by anyone as it has only been on the market for a few years. Thus, any long-term side effects have not yet had a chance to emerge.

Is Soylent Worthwhile?

Soylent can be extremely worthwhile if you live a busy life and don’t like spending a lot of time or money on normal meal preparation. Cooking is not fun for everyone and there are plenty of people that would prefer to get their dietary needs out of the way so that they can focus on other aspects of their day.

If you struggle with bad eating habits, replacing meals with Soylent may prove to be a viable solution. However, Soylent does not automatically get rid of bad eating habits and good discipline and exercise will also be required to achieve significant weight loss.

Overall, Soylent can be a huge benefit if its advantages suit the lifestyle you wish to achieve.

How is it Different from Other Meal Replacements?

Compared to other meal replacements like Ensure and Light Fuel, Soylent as the better balance of major macromolecules. For instance, Ensure has more sugar than Soylent, which can cause trouble for some people who already struggle with sugar intake. Light Fuel has fewer carbohydrates than Soylent and can leave many with the feeling that their stomach is empty.

Soylent is different since it strives to be the perfect replacement for all types of people. It balances health with satisfaction.
