NOW Foods Magnesium Glycinate with BioPerine 60 Veg Capsules

What it is

NOW Foods Magnesium Glycinate with BioPerine is a dietary supplement sold as a bottle of 60 vegetarian capsules. Each serving is 2 capsules, and the bottle holds 30 servings. Every serving supplies 200 mg of elemental magnesium from Albion magnesium bisglycinate, together with 2.5 mg of black pepper fruit extract standardized as BioPerine. The front of the bottle carries Non-GMO and Vegetarian/Vegan marks and the words "A Dietary Supplement"; the back names NOW Foods of Bloomingdale, Illinois as the manufacturer, a family-owned company since 1968. You can browse the wider Supplements range for other formats and mineral forms.

What's in the capsules

The panel lists just two active entries, so it is worth walking through both plus the capsule's supporting ingredients.

• Magnesium (elemental), 200 mg — 48% Daily Value. The word "elemental" is doing real work here. The panel figure is the weight of the magnesium itself, not the weight of the compound carrying it, so 200 mg of elemental magnesium comes from a noticeably larger quantity of raw material. The label names that material as magnesium bisglycinate from Albion, a trademark of Balchem Corporation.
• What "bisglycinate" means. Glycine is the smallest of the amino acids. In a bisglycinate, two glycine molecules are bonded to one magnesium atom — "bis" is simply Latin for twice — producing what chemists call a chelate, a mineral held inside an organic carrier rather than paired with a simple inorganic salt. The NIH Office of Dietary Supplements fact sheet on magnesium gives general background on the mineral and the forms it is sold in.
• Black Pepper Fruit Extract (BioPerine), 2.5 mg. BioPerine is a registered trademark of Sabinsa Corporation for an extract of black pepper fruit — Piper nigrum, the same vine that produces the peppercorns in a kitchen grinder. The panel specifies a minimum of 96% piperine, the compound responsible for black pepper's pungency. This entry carries a dagger on the panel, which the label explains as "Daily Value not established" — no reference intake has been set for it. General background on plant-derived ingredients is available from the NIH ODS overview of botanical dietary supplements.
• Other ingredients. Five, printed in this order: hypromellose (the cellulose capsule shell), citric acid, ascorbyl palmitate, microcrystalline cellulose and silicon dioxide. Hypromellose is derived from plant cellulose, which is why the bottle can print Vegetarian/Vegan — there is no gelatin here. Ascorbyl palmitate is a fat-soluble ester of ascorbic acid used as an antioxidant, microcrystalline cellulose is a purified plant fiber used to bulk a capsule fill to a consistent volume, and silicon dioxide is a flow agent that stops fine powder clumping in the filling machine.

Supplement Facts

How to use it

The label's suggested usage is to take 2 capsules 1 to 2 times daily with food. That is the whole of the printed direction — the bottle sets no particular time of day and gives no separate instruction for first-time users. Taken as one serving a day, a bottle is a 30-day supply; at two servings a day it is 15 days. Storage guidance on the bottle is to store in a cool, dry place after opening.

Who it's for

This is a straightforward single-mineral supplement for adults 18 and over who already know they want magnesium in a glycinate form rather than a general multivitamin. The two-capsule serving splits the amount across two smaller vegetarian capsules instead of one large tablet, and the flexible 1-to-2-times-daily direction means the same bottle covers either a lighter or a fuller routine without a second product. Because the capsule shell is plant-derived and the formula is made without the major allergens listed below, it also suits shoppers working around vegetarian, vegan or gelatin-free requirements. If you are comparing mineral forms before deciding, the Vitamins category lists the neighboring options.

Good to know

• Allergens, as printed: not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients. The label adds that it is produced in a GMP facility that processes other ingredients containing these allergens.
• The caution on the bottle, in full: for adults only; consult a physician if pregnant or nursing, taking medication, or if you have a medical condition; keep out of reach of children.
• Appearance: the label notes that natural color variation may occur in this product.
• Manufacturing: the back panel reads "Made and quality tested in the USA with globally sourced ingredients" and the bottle carries a GMP Quality Assured seal.
• Packaging: the bottle is made from 100% PCR — post-consumer recycled — resin, a detail printed alongside the storage line.

Frequently Asked Questions

How many capsules are in the bottle, and how many servings is that?

There are 60 vegetarian capsules in the bottle, which the panel divides into 30 servings of 2 capsules each. At one serving a day that works out as a 30-day supply, and at the upper end of the label's direction — two servings daily — as 15 days.

Is this suitable for vegetarians and vegans?

Yes. The front of the bottle prints both "Vegetarian/Vegan" and a Non-GMO mark, and the capsule shell is named on the panel as hypromellose, a cellulose material derived from plants rather than gelatin.

What is BioPerine, and how much is in a serving?

BioPerine is Sabinsa Corporation's registered trademark for a black pepper fruit extract, and each 2-capsule serving contains 2.5 mg of it. The panel specifies a minimum of 96% piperine and marks the entry with a dagger, meaning no Daily Value has been established for this ingredient.

Does the formula contain common allergens?

The label states it is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients. It also states that production takes place in a GMP facility that processes other ingredients containing those allergens, so anyone with a severe allergy should weigh that shared-facility note.

How is the order packaged for delivery?

Orders ship in plain, unbranded outer packaging with no description of the contents on the outside. It will not show the Gear Isle name.
