🧪 Formulation Notes

Solgar's L-Tyrosine Vegetable Capsules are free of corn, yeast, wheat, soy, gluten and dairy products and are formulated without the use of artificial preservatives, flavors and colors.

Solgar's KOF-K certification #K-1250

(Free form)

Suitable for vegetarians

Sugar, salt and starch free

Long chains of molecularly bonded individual amino acids form protein. The body must first break these molecular (peptide) bonds for amino acid absorption to take place. Solgar's free form amino acids are already in their simplest form (no peptide bonds) and can be readily absorbed into the bloodstream.

Additional Information

To assure freshness and potency, store at room temperature 59 degrees-86 degrees F (15 degrees-30 degrees C). Store away from heat, light and moisture.

Solgar since 1947
