NOW Foods L-Tryptophan, 500mg

Tryptophan is an essential amino acid found naturally in foods like turkey and milk, and NOW Foods supplies it here in a clean 500mg vegetarian capsule.

As with the rest of the NOW amino range, the label is single-ingredient and fully stated. Bottles come in 60 and 120 vcap counts, a smaller spread than some products in the line, reflecting its more specialist audience.

• 500mg L-tryptophan per capsule
• Essential amino acid
• 60 or 120 vegetarian capsules
• Clean single-ingredient label

Like the rest of the amino line, both bottle sizes are listed together at NE Commerce.
