NOW Foods Calcium D-Glucarate 500mg 90 Veg Capsules

What it is

NOW Foods Calcium D-Glucarate is a dietary supplement supplying 500 mg of calcium D-glucarate per capsule, packed in a bottle of 90 vegetarian capsules. The bottle front carries the NOW logo, the strength, a Non-GMO mark and the words "A Dietary Supplement" and "Vegetarian/Vegan"; the shoulder band on the back of the bottle files it under NOW's Minerals range. Each capsule is a plain, uncoated veg capsule — the label notes that natural color variation may occur from batch to batch.

Calcium D-glucarate is the calcium salt of D-glucaric acid. The bottle describes D-glucaric acid as a substance the body produces naturally in small amounts, and one that is also found in many fruits and vegetables. On this product the panel lists it in its tetrahydrate form, which is the hydrated crystalline form the raw material is supplied in.

What's inside

The panel declares one active compound alongside the capsule shell and two processing ingredients.

• Calcium D-Glucarate (Tetrahydrate Form) — 500 mg. The active compound in the capsule. The panel marks it with a dagger and footnotes "Daily Value not established", which is the standard notation for a substance that has no official reference intake set for it.
• Calcium — 60 mg (5% Daily Value). This is not a separate added ingredient. The panel prints it as "(from Calcium D-Glucarate)" — it is the mineral content carried by the 500 mg above, declared separately because calcium has an established Daily Value. If you are tracking calcium intake generally, the NIH Office of Dietary Supplements publishes a plain-language consumer fact sheet on calcium covering reference intakes and food sources.
• Other ingredients: cellulose (capsule), cellulose powder and stearic acid (vegetable source). The cellulose capsule shell is what makes the product suitable for vegetarian and vegan diets rather than a gelatin shell. The panel assigns no role to these, so neither do we — they are listed exactly as printed.

Supplement Facts

† Daily Value not established. Other ingredients: cellulose (capsule), cellulose powder and stearic acid (vegetable source). Transcribed from the Supplement Facts panel printed on the bottle.

How to use it

The label's Suggested Usage is to take 1 capsule 3 times daily. That works out to three capsules across a day, so a 90-capsule bottle covers 30 days at the suggested usage. The bottle gives no instruction to take it with food or at a particular time of day, so none is implied here.

Storage is simple: store in a cool, dry place after opening. Two further handling notes are printed on the side panel — "Do Not Eat Freshness Packet" and "Keep in Bottle", which asks you to leave the capsules in their original bottle alongside the freshness packet rather than decanting them elsewhere.

Who it's for

This is a single-compound mineral supplement for adults who already know what calcium D-glucarate is and want it on its own rather than blended into a multi-ingredient formula. The 500 mg per-capsule strength and the three-times-daily usage make it a product for someone following a specific regimen, not a general daily multivitamin — if that is what you are after, the broader supplements range is a better starting point.

The capsule shell is cellulose rather than gelatin, so it suits vegetarian and vegan diets. The label states "For adults only" and explicitly says not to take it if you are pregnant or nursing. Anyone taking prescription medication or managing a medical condition is directed by the label to consult a physician first — and that is worth doing before adding any new supplement, as the NIH explains in its overview of what you need to know about dietary supplements.

Good to know

The printed caution reads: for adults only; do not take if you are pregnant or nursing; consult a physician if taking medication or if you have a medical condition; keep out of reach of children.

Allergen statement, as printed: not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens. That second sentence matters if you are highly sensitive — shared-facility processing is disclosed rather than ruled out.

The bottle carries a GMP Quality Assured seal and the line "Family owned since 1968." The manufacturer is given on the back of the bottle as NOW Foods, 395 S. Glen Ellyn Rd., Bloomingdale, IL 60108, USA.

Orders from Health & Wellness ship in plain outer packaging. It will not show the Gear Isle name.

Frequently Asked Questions

How many capsules are in the bottle, and how many days does that cover?

There are 90 vegetarian capsules in the bottle. At the label's Suggested Usage of one capsule three times daily, that is a 30-day supply. Each capsule supplies 500 mg of calcium D-glucarate.

Is this suitable for vegetarians and vegans?

Yes — the capsule shell is cellulose, not gelatin, and the front of the bottle is marked "Vegetarian/Vegan". The only other ingredients are cellulose powder and stearic acid from a vegetable source, both named on the panel.

How much actual calcium does a capsule provide?

Each capsule provides 60 mg of calcium, which the panel lists as 5% of the Daily Value. That calcium is not added separately — the panel prints it as "(from Calcium D-Glucarate)", meaning it is the mineral content of the 500 mg of calcium D-glucarate itself.

Does it contain common allergens?

The label states it is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. It also states that it is produced in a GMP facility that processes other ingredients containing these allergens, so cross-contact is disclosed rather than excluded.

Who should not take it?

The label states it is for adults only and says not to take it if you are pregnant or nursing. It also directs anyone taking medication or managing a medical condition to consult a physician before use, and to keep the product out of reach of children.
