NOW Foods L-Tyrosine 500mg 120 Capsules

What it is

NOW Foods L-Tyrosine 500 mg is a single-ingredient amino acid supplement sold in a bottle of 120 capsules. Each capsule supplies 500 mg of free-form L-tyrosine, and the Supplement Facts panel declares one active row and nothing beside it. The bottle is white with a purple cap and an orange wrap label, and the shelf banner printed across the top of the panel reads "Amino Acids", which is NOW's own wording for the range this bottle belongs to.

On this site the item is listed under Amino Acids and Supplements.

What's in the capsule

The Supplement Facts panel declares exactly one active row: L-Tyrosine (Free-Form) 500 mg, carrying a double asterisk against the footnote "Daily Value not established." That footnote is the panel's own explanation for the empty percentage column — a Daily Value is a regulatory reference figure, and the label states that none has been set for this ingredient.

Tyrosine is one of the amino acids that make up dietary protein, and it occurs in ordinary protein-containing foods as well as in supplement form. "Free-form" is the part of the name worth unpacking: it means the amino acid is supplied on its own rather than bound into a protein chain. It describes the physical state of the raw material in the capsule, not anything about what a capsule will do for any individual.

The label also prints, in its own words, that "The L-Tyrosine used in this product is pharmaceutical grade", and carries "Pharmaceutical Grade" as a bullet on the front of the bottle. That is the manufacturer's own description of the grade of raw material used, quoted here as printed.

Three other ingredients are declared on the panel:

• Hypromellose (cellulose capsule) — the capsule shell. Hypromellose is derived from plant cellulose; the panel's bracketed note names it as the capsule material.
• Stearic Acid (vegetable source) — a fatty acid common in supplement manufacturing. The label specifies the vegetable source in brackets rather than leaving the origin open.
• Silicon Dioxide — a fine mineral powder, one of the most common excipients in dry-filled capsules and tablets.

That three-item line is the whole of what the panel declares alongside the tyrosine, and it is worth reading in full rather than skimming. The NIH Office of Dietary Supplements fact sheet index and the NIH Dietary Supplement Label Database are general references for reading supplement panels; neither refers to this product.

How to use it

The label's Suggested Usage reads: "Take 1 capsule 1 to 3 times daily, preferably between meals." That is the whole of the printed instruction — the bottle gives a range rather than one fixed daily serving, and "between meals" is the only timing guidance printed anywhere on the pack.

Because a serving is a single capsule, the arithmetic on a 120-capsule bottle is easy to do in advance: at one capsule a day the bottle covers 120 days, and at the label's upper rate of three a day it covers 40. Storage is printed too: "Store in a cool, dry place after opening."

One more line sits on the panel in bold, and it is there to set expectations about appearance rather than about use: "Natural color variation may occur in this product."

Who it's for

This is a product for adults who want a single amino acid at a measured 500 mg per capsule rather than a multi-ingredient formula. The label restricts it to adults. A one-row panel is straightforward to account for alongside anything else already in a routine, because there is only one declared active amount to track, and the 120-count bottle is a stocking size rather than a sample.

The capsule shell is hypromellose rather than gelatin, which the panel states plainly. More of the range is listed under Health & Wellness.

Good to know

The bottle prints a caution paragraph, and it is specific rather than generic. In full: "For adults only. Consult physician if pregnant/nursing, taking medication, or have a medical condition. Persons with thyroid disease (hyperthyroidism), melanoma, or those taking MAO inhibitors or other mood altering medications should seek the advice of a physician before consuming this product. Keep out of reach of children."

That named list is printed by the manufacturer on this label, and anyone it covers should take the instruction to speak to a physician at face value rather than reading around it. General background on supplement safety, and on what supplement labels are and are not required to tell you, is published by NCCIH and the NIH Office of Dietary Supplements; neither source refers to this product.

Three further things are printed on the pack and worth recording accurately. The bottle carries a "GMP Quality Assured" roundel and the line "Family owned since 1968." The front carries a Non-GMO mark. The bottle is described as "made from 100% PCR (post-consumer recycled) resin." No California Prop 65 warning is printed on this label.

Frequently Asked Questions

How much L-tyrosine is in one capsule, and how many capsules come in the bottle?

Each capsule contains 500 mg of free-form L-tyrosine, and the bottle holds 120 capsules. The Supplement Facts panel sets the serving at one capsule, so one capsule is one full serving at the stated 500 mg.

What does "free-form" mean on this label?

Free-form means the amino acid is supplied on its own rather than bound into a protein chain. It is a description of the raw material's physical state, and it is why the panel can state one clean milligram figure in a single row.

Is the capsule shell gelatin?

No — the panel declares the shell as "Hypromellose (cellulose capsule)", which is derived from plant cellulose rather than from animal gelatin. The only other declared ingredients are stearic acid from a vegetable source and silicon dioxide.

Does the label say anything about allergens?

Yes, and it says two things that belong together. The panel states the product is "Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients", and then adds that it is "Produced in a GMP facility that processes other ingredients containing these allergens."

How is the order packaged for delivery?

Orders ship in plain outer packaging. It will not show the Gear Isle name.
