DLPA

DL-Phenylalanine (DLPA) is a mixture of the essential amino acid, L-phenylalanine and its mirror image, D-phenylalanine. DLPA has some of the effects of both forms of phenylalanine, although most people take it for the Discomfort-relieving effects of D-phenylalanine. It is the only natural Discomfort reliever and antidepressant available.

• Despair.

• Alcohol abuse. 

• Discomfort of weight bearing Joints. 

• Rheumatoid arthritis.

• Vitiligo. 

• Dental Discomfort.

• Recurring headaches. 

• Parkinson’s problem.

• Discomfort in arthritis.

• Symptoms of premenstrual syndrome (PMS).

• Obesity.
  

DLPA has been used in amounts ranging from 75 to 1,500 mg per day. As this compound can have powerful effects on mood and on the nervous system, DLPA should be taken only under medical supervision.

DLPA does not occur naturally. It was first isolated from the lupine plant. Protein foods such as poultry, meats, soybeans, fish, dairy products, nuts, and seeds are rich in L-phenylalanine. D-phenylalanine is much less common in foods. However, when phenylalanine is synthesized in the laboratory, half appears in the L-form and the other half in the D- form. DLPA comes in capsules and tablets that range in potency from 375 to 750 mg. It is sometimes combined with vitamins B5 and B6.

Forms of phenylalanine can cause symptoms of over-stimulation in some people, such as Disturbance in sleep and nervousness, although DLPA is generally less stimulating than L-phenylalanine. On few occasions people have reported headaches or nausea from DLPA intake. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or which is especially bothersome.

Acute overdose: None
Chronic overdose: None

• Although there are no well-known drug interactions with either L-phenylalanine or D-phenylalanine, individuals taking prescription or over-the-counter medications should consult a nutritionally oriented physician before taking DLPA. 

• Anyone with high blood pressure and women who are pregnant or lactating should avoid all forms of phenylalanine supplements

• Phenylalanine should not be used with antidepressants drugs such as MAOI's or SSRI's.

• Children, people with psychosis, and those suffering from malignant melanoma or phenylketonuria, should also not take phenylalanine supplements. 

• L-phenylalanine competes with several other amino acids for attachment on a common amino acid carrier in the body. Therefore, it should not be taken with protein-containing foods.
