What Is Gelatin?

Gelatin is a protein-based product that is commonly used in baking and confectionery as a stabilizing agent. It is derived from collagen that is obtained from boiling the bones, joints, and connective tissues of animals (pigs and cows mostly). Apart from being used in food as a stabilizing ingredient, gelatin is also used in some skincare and hair care products.

Since gelatin is generally derived from animals, it is not vegan. However, there are a few alternatives to gelatin that are not made from animal tissue. Find out what they are in the next section.

Alternatives To Gelatin

Since gelatin generally is made from pig and cow bones, it is not considered to be kosher or halal. Fortunately, there are plant and fruit-based alternatives that are vegan and can be used as a substitute to their meat-based counterpart.

  •  Agar-agar

This variety of gelatin is derived from cooked and pressed seaweed. Seaweed is boiled until it becomes a gel-like consistency, which is later pressed and dried. Once it dries, it is crushed into a fine or flaky powder. You can use agar-agar as a direct substitute for regular gelatin in most of your recipes. However, if your recipe requires citrus fruits like lemons and oranges, you will need to use double the amount required.

  •  Carrageen

This is another variety of vegetarian gelatin that is also made from seaweed (Irish moss).

  •  Pectin

Pectin is fruit-based gelatin that is commonly found in citrus fruits. It is a commonly found ingredient in fruit-based yogurt, that helps enhance the flavor and mouthfeel. It is also used in homemade jams and jellies.

You can choose any one of these three varieties of gelatin and add them to your recipe. Now let us see how nutritious gelatin is, in the next section.

From the above table, it is quite evident that gelatin is rich in protein and has zero sugar, fat, salt, and carbs. How exactly does this benefit your health? Find out in the next section.

Health Benefits Of Gelatin

Gelatin is rich in proteins, especially collagen and amino acids that benefit your health in numerous ways (2). Let’s find out what some of these potential health benefits are:

  •  Good For Your Bones And Joints

Gelatin contains amino acids like glutamic acid that are known to improve bone health (3). Research on rats suggests that gelatin might be helpful in improving the bone mineral content, thereby strengthening the bones (4). However further studies are required to determine its effectiveness on human bones.

The word “gelatin,” comes from the Latin word “gelatus,” meaning frozen or stiff.
  •  Good For Your Skin And Hair

Gelatin is also a rich source of collagen that is beneficial for your skin health and hair. Studies suggest that collagen may help keep your skin hydrated and moisturized (5). Gelatin might also help increase hair mass and volume. A study on volunteers in the age group of 21-28 years revealed that those who received gelatin supplements saw a 30% increase in hair mass and volume (6).

Jacqueline, a blogger, shared how her skin and hair improved once she began consuming gelatin. She gushes, “My hair has gotten crazy thick. Crazy, I tell you. My hair was always fairly thin. Lately, though, it takes me twice as long to dry and style my hair. Maybe it’s just my imagination, but I’m thinking my hair is thicker since consuming gelatin. My nail strength and growth have also improved. My nails broke easily and now I couldn’t bite them off if I tried (i).”

  •  Might Benefit Brain And Memory Functions

Gelatin also contains an amino acid called glycine that is known to improve memory function. According to a study, consuming glycine significantly improves the memory of young and middle-aged people (7). The study also suggests that it may help benefit those who are diagnosed with schizophreniai  A mental disorder that makes a person interpret reality abnormally and impairs their capacity to think, feel and behave appropriately. and Parkinson’s diseasei  A chronic disorder in which parts of the brain are damaged, affecting the nervous system and the body parts controlled by the nerves. .

There is a small amount of research to suggest that glycine present in gelatin might also be useful in relieving the symptoms of OCD and body dysmorphic disorderi  A mental health disorder where an individual spends a lot of time worrying over flaws in their appearance. (BDD) (8).

  •  May Assist In Weight Loss

Gelatin might be helpful in losing weight as it is rich in protein and contains no carbs or fat. Studies suggest that consuming gelatin releases a hormone called ghrelin that makes you feel full and thereby makes you want to eat less (9). Studies have also shown that a high protein diet helps lower fat levels that might lead to weight loss (10).

  •  Might Help You Sleep Better

Glycine present in gelatin may have therapeutic effects that may help improve your sleep. Research suggests that oral administration of 3 grams of glycine before bedtime may help improve sleep and reduce sleepiness and fatigue during the daytime. Glycine might also help reduce your core temperature and increase the duration of REM sleep (rapid eye movement) (11).

  •  Might Improve Your Digestive Health

Gelatin contains glutamic acid that gets converted to glutamine when absorbed by your body. Glutamine is known to strengthen the lining of your gut wall by reducing its permeability and protecting it from bacterial infection. It may also help reduce inflammation in your gut (12).

  •  Might Slow Down The Growth Of Cancer

Studies on mice have shown that gelatin obtained from pigskin might reduce the size of cancerous tumors and increase life span (13). Further research is required to prove its effectiveness on humans.

These potential health benefits of gelatin make it a good addition to your diet. Let us see if there are any side effects to eating gelatin.

Allergies And Adverse Effects

When it comes to allergies, studies suggest gelatin may cause allergic reactions to certain vaccinations that contain gelatin as a stabilizing agent (14). A report by the CDC suggests measles vaccinations that used gelatin as a stabilizing agent may have allergic reactions such as anaphylactic shocki  It is the outcome of a strong allergic reaction that lowers blood pressure, narrows the airway, and makes breathing difficult. (15). In the same report, the CDC also states that only a single case of such a reaction has been reported in the USA to date. Further research is required to establish a link between gelatin and its side effects on certain vaccinations. The USFDA has regarded gelatin to be generally safe for consumption (16).

In 2020, Brazil was the world’s largest gelatin exporter ($338M) while the US was the biggest importer ($318M).

Having understood the benefits and side effects of gelatin, let us learn how to prepare gelatin at home in the next section.

How To Prepare Gelatin At Home

Gelatin can be prepared using the bones and ligaments of various animals. However, pork, beef, and chicken bones are the most commonly used.

Here is how you can prepare gelatin at home.

Ingredients Required

  •  4-5 pounds of beef, pork, or chicken bones and connective tissue.
  •  1 tablespoon of salt
  •  2-3 liters of water


  1.  Transfer all the bones and connective tissue to a large pot or slow cooker and add salt.
  2.  Pour enough water so that the bones are completely covered.
  3.  Bring the contents to a boil and let it cook for 5-7 minutes.
  4.  Reduce the heat and let it simmer for a minimum of 48 hours.
  5.  Strain the liquid with a sieve and allow it to cool.
  6.  Once the liquid cools, it will begin to solidify into gelatin.

Making gelatin at home is fairly simple, but it can be a time-consuming process. If you don’t have the time to make gelatin from scratch, you can buy it from a grocery store. However, if you have made gelatin from scratch, you need to know how to store and preserve it. Learn more about this in the next section.

Tips For Storing Gelatin

Freshly prepared gelatin can be stored for up to a week in the fridge, and up to a year when frozen. You can also add fruit flavoring agents to freshly prepared gelatin and make ice cubes for later use.

Let’s put that gelatin to good use with some easy recipes.

Gelatin Recipes
