Remedy's Nutrition



Many have heard of Lysine as a treatment for herpes cold sores.  Lysine (L-Lysine) is a 'proteinogenic' amino acid.  This means that it is a building block of protein. It is one of the nine essential amino acids.  WebMd states: 'Research suggests that lysine seems to reduce cold sores when taken by mouth and also when applied as a cream to the skin'.

Mechanism of Action (How Lysine Works)

Research seems to support that lysne reduces cold sores when it is ingested by mouth or applied to affected areas of the skin in a cream formulation.  However, the research does not seem to support a reduction in recurrence or severity.

Nutrional Sources

The term 'essential' refers to the fact that the body cannot manufacture lysine, but must take it in from food or supplements.   Foods like meats, pork, chicken, fish (especially sardines and cod), eggs, dairy (especially Parmesan cheese), nuts and beans (especially soybeans and tofu), Brewer's yeast and other protein-rich foods are good sources of lysine. Nuts are a particularly good source of lysine for herpes sufferers because lysine balances the effect of arginine. Lysine can be taken in supplement form.  Remedy's Lysine features the more desirable L- form, as L-form aminos are natural to the body, unlike the D- or DL-forms.  

Nutritional Need for Lysine

Lysine is also needed by the body to make carnitine. Carnitine in turn helps convert fatty acids into energy,  improves absorption of calcium, and supports production of collagen, which improves bone building and building of connective tissue like tendons and skin. Vegetarians can obtain sufficient lysine by consuming cereal grains and legumes. In the body, lysine plays a major role in calcium absorption and building muscle.  Lysine is helpful when recovering from injuries or surgery.  The body also uses lysne to produce hormones, antibodies and enzymes. 


Diabetes: In early studies, taking lysine twice a day for two months decreased blood sugar levels in diabetic patients pre-medical treatment.

Pregnancy & breastfeeding:  Safety of this supplement has not been established in these conditions.  Best to follow best practice and avoid.

Bone Disorders:  When taken with calcium supplements, lysine might increase calcium absorption.  Conslt your physician for benefits of supplementation in cases of ostopenia and osteoporosis.

Lysinuric protein intolerance: In children intolerant to lysinuric protein, ingestion may cause diarrhea and stomach cramps.
