PROLINE Overview Information
Proline is an amino acid, or a building block for protein. The body can make proline on its own, but it is also consumed in the diet. A typical diet contains about 5 grams of proline daily. The primary sources are protein-rich foods including meat, fish, and dairy. Proline can also be taken as a supplement.
Proline is used for skin healing, especially in people who have problems keeping enough proline in the body. It is also used for other conditions, but there is no good scientific evidence to support any of these uses.
In medicine, proline is used as a stabilizer to help some prescription products last longer.
How does it work?
The body uses proline to make proteins, such as collagen. Collagen is found in the skin, bones, and joints. Proline is also involved in the general function of cells.
PROLINE Uses & Effectiveness 
Insufficient Evidence for:
- Athletic performance. Teens who eat more proline in the diet don't seem to be any more physically fit than teens who eat less proline.
- Low bone mass (osteopenia). Eating more proline in the diet doesn't seem to protect against osteopenia.
- Weak and brittle bones (osteoporosis). Eating more proline in the diet doesn't seem to protect against osteoporosis.
- Fractures.
- Fatigue.
- Insomnia.
- Infections.
- Wrinkles.
- Wound healing.
- Skin ulcers.
- Defects in proline metabolism.

PROLINE Dosing
The appropriate dose of proline depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for proline. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
