L-Proline: Our Picks
Guide: Questions you should ask yourself before buying L-Proline
What is L-proline and what effects does it have?
The human body makes the amino acid L-proline from glutamic acid. L-proline is an important collagen building block and is found in the proteins of your connective tissue, as well as in bones and cartilage, where it has regenerative effects. (1)
Furthermore, L-proline protects against collagen degradation by blocking digestive enzymes called collagenases. If there is a lack of L-proline, the enzymes mentioned work more intensively and connective tissue is broken down. (2)
Therefore, a sufficient supply of the amino acid is important. This is especially true in old age or in the case of chronic and protracted illnesses. Here, the risk of a deficiency condition increases, as the body's own production of L-proline is often no longer sufficient.
A deficiency can also lead to joint problems, a general drop in performance or instability of the arterial walls. (2)
Where is L-proline found?
The following table gives you an overview of foods containing proline. The information corresponds to the amount of L-proline per 100g of the food:
| Food | L-proline per 100g |
|---|---|
| Cheese (Emmental, Edam, Tilsiter, Appenzeller, Camembert, Brie) | 2,160 - 3,500mg |
| Soybeans | 2,820mg |
| Beef | 950 - 1,780mg |
| Peanuts | 1,450mg |
| Rusk | 1,290mg |
| Lentils | 1.040 - 1,220mg |
| millet | 1,090mg |
| tuna, sole | 890mg |
| fish (salmon, redfish, plaice, mackerel, trout, sardine, lobster) | 710 - 850mg |
| oatmeal | 840mg |
| pork | 755mg |
| walnuts | 600mg |
How much does L-proline cost?
| Online | Price per 100g |
|---|---|
| Powder | 6€ to 12€ |
| Capsules | 12€ to 20€ |
| Tablets | 10€ to 18€ |
You usually have to pay more in the pharmacy or health food store than online.
However, here you have the advantage of being advised and getting helpful tips if necessary. Capsules cost around 70€ on average.
In what dosage is L-proline available?
Decision: What types of L-proline are there and which is right for you?
L-proline is usually offered in its pure form. You have the choice between the following types:
- Capsules
- Tablets
- Powder
However, there are also useful combinations that can be helpful, especially in the case of illness. The most popular combination is L-proline together with vitamin C.
The different types each have advantages and disadvantages. Depending on what you prefer, a different type is suitable for you. The following section is designed to help you decide.
What are the advantages and disadvantages of L-proline capsules?
Capsules are usually made of animal gelatine and are therefore often unsuitable for vegetarians. However, there are also vegetable alternatives for the capsule shell.
If this is a decisive criterion for you, it is best to find out about the ingredients directly from the manufacturer.
Moisture or air can make them brittle and sticky, so they should be stored in a dry place.
What are the advantages and disadvantages of L-proline tablets?
Tablets are a classic form of administration and are absorbed by the body in the digestive tract.
They have a very long shelf life, which is why you can easily buy larger quantities and possibly benefit from a price advantage.
Tablets are taken with a glass of water.
What are the advantages and disadvantages of L-proline powder?
Powder is usually only available in very large quantities and is less suitable if you want to test the food supplement first.
In addition, it is not yet dosed in the usual 500mg and you would have to measure it yourself first.
Some suppliers include a measuring spoon with the delivery, which should make it easier for you to measure out.
Buying criteria: You can use these factors to compare and evaluate L-proline
In the following, we will show you which aspects you can use to decide between the many L-proline products.
The criteria you can use to compare L-Proline products include:
- Dosage
- Package size
- Suitability for lifestyle / diet
In the following paragraphs, we will explain to you what is important in the individual criteria in order to make your purchase decision easier.
Dosage
It is best to discuss the intake of L-Proline with your doctor. He or she can best decide on the dosage.
Manufacturers recommend taking one to two L-Proline capsules per day, each containing 500mg per capsule or tablet.
Package size
L-Proline is available in different quantities. Common sizes are:
- 60 capsules or tablets 500mg each
- 100 capsules or tablets 500mg each
- 120 capsules or tablets of 500mg
- 150 capsules or tablets per 500mg
- 500g powder, equivalent to 1,000 L-proline capsules/tablets each 500mg
When choosing a pack size, you should decide beforehand how long you want to take the food supplement or whether you want to test it first.
If you take 500 mg of L-proline twice a day, the smallest size (60 capsules) will last for about a month.
If you decide to take the powder, you should already have experience with L-proline and the dosage or be sure that you want to take it long-term.
Suitability for lifestyle / diet
As you may have already noticed, the manufacturers of the food supplement advertise heavily with the buzzwords vegan, gluten-free or GMO-free.
This is usually just a ploy to get lots of clicks. By and large, almost all pure L-proline products on the market are:
- Vegan
- Without artificial additives
- Without genetic engineering
- Gluten-free
- Lactose-free
Capsules are an exception here. The capsule shell is often made from gelatine, which is an animal product.
However, there are also plant-based alternatives that guarantee a vegan product.
You have to take a closer look at the ingredients of the products. If the manufacturer has not published them, you can contact them by email or phone.
Facts worth knowing about L-proline
Finally, we would like to answer a few important questions about L-proline and its intake.
You will learn what non-essential amino acids are and where L-proline can be classified, how it is taken and what side effects can occur when taking it.
What are non-essential amino acids and where can L-proline be classified?
Non-essential amino acids are the basic building blocks of proteins and can be produced by the body itself in sufficient quantities.
As a rule, they do not have to be supplied from outside. This is also the difference to essential amino acids.
They are not produced by the body and must be taken in externally through food or dietary supplements.
Strictly speaking, L-proline belongs to the semi-essential amino acids. These can also be produced by our body through synthesis.
The difference lies in the fact that L-proline is no longer sufficiently produced in certain circumstances, such as old age or certain illnesses, and must be taken in via

Dietary supplements. Besides L-proline, these also include:
- Arginine
- Asparagine
- Cysteine
- Glutamine
- Glycon
- Tyrosine
How is L-proline taken?
Classically, L-proline tablets and capsules are swallowed. If you have chosen one of the two forms of administration, you should make sure to take it with sufficient liquid.
If you take L-proline in a loose powder, dissolve it in water and drink it.
What side effects or interactions can occur when taking L-proline?
No side effects or interactions are known so far.
What happens if I take too much L-proline?
A negative effect of an overdose of L-proline has not been found so far. However, in this case you should consult your doctor.
What additives are available with L-proline and what effect do they have?
L-proline protects your cell walls from becoming brittle and unstable. The flexibility of the artery walls is particularly important because it prevents mutated cells from penetrating through the cell walls.
This is why L-proline is often used in cancer treatments in combination with high doses of vitamin C and L-lysine.
The combination of L-proline and vitamin C can also relieve pain in the knee, shoulder and neck areas in cases of osteoarthritis. (4)
By combining it with vitamin C, your body can produce hydroxyproline from L-proline. This is used to form structural proteins such as collagen and elastin and helps regenerate inflammation in bones and cartilage.
In addition, it supports joint reconstruction and tissue regeneration. (1)
There are also some products on the market that contain L-proline and L-lysine. Here, it is usually recommended to take additional vitamin C.
A combination of L-proline, vitamin C and collagen is also available. As already mentioned, L-proline promotes collagen formation.
Another option are amino acid complexes that contain several amino acids in addition to L-proline, such as leucine, methionine or tryptophan.
