Below is general information about the safety of the known ingredients contained in the product Dr. Hulda Clark's L-A Formula. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts found in foods (94500).
POSSIBLY SAFE ...when aspartic acid is used orally and appropriately, short-term. D-aspartic acid 3-6 grams daily has been used with apparent safety in clinical trials for up to 3 months (94497,97576). L-aspartic acid has been used in doses up to 8 grams daily, short-term, without reports of adverse effects (94500).
CHILDREN: POSSIBLY UNSAFE
when aspartic acid is used orally in infants.
In rodents, aspartic acid given orally within a few days of birth caused neuronal necrosis in the hypothalamus. This adverse effect was not seen in nonhuman newborn primates and has not been assessed in humans. Until more data is available, the Institute of Medicine (IOM) and the Food and Nutrition Board advise that aspartic acid be avoided in infants (94500).
There is insufficient reliable information available about the use of aspartic acid supplements in children and adolescents; avoid using in amounts exceeding those found in food.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts found in foods (94500).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when aspartic acid is used orally.
In rodents, aspartic acid given orally within a few days of birth caused neuronal necrosis in the hypothalamus. This adverse effect was not seen in nonhuman newborn primates and has not been assessed in humans. Until more data is available, the Institute of Medicine (IOM) and the Food and Nutrition Board advise that pregnant or breast-feeding women avoid the use of aspartic acid (94500).
POSSIBLY SAFE ...when used orally in doses up to 3000 mg daily for up to one year (1114,1119,1120,90642,104104), or up to 6000 mg daily for up to 8 weeks (90644,90645). ...when used topically and appropriately, short-term (11051).

Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Details
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane (19400).
