NOW Foods Inositol Powder Vegetarian 4 oz

What it is

NOW Foods Inositol Powder is a single-ingredient dietary supplement containing 4 oz. (113 g) of pure myo-inositol powder. The Supplement Facts panel lists exactly one entry — inositol powder, 730 mg per 1/4 level teaspoon — followed by the line "Other ingredients: None." There is no filler, no flavoring, no anticaking agent and no capsule shell. The front of the bottle marks the contents Vegetarian/Vegan and Non-GMO and carries a plain K symbol, and the shoulder band files it under the brand's Vitamins range.

The packaging is a white plastic bottle with a purple screw cap and an orange front panel. NOW Foods lists itself on the label as family owned since 1968, with an address at 395 S. Glen Ellyn Rd., Bloomingdale, Illinois, and states that the product is packaged and quality tested in the USA.

What's inside

Inositol is a carbohydrate-like compound that the label describes as a non-essential member of the B-complex family. "Non-essential" is a nutritional classification, not a judgment of value: it means the human body makes the compound itself, so no dietary requirement has been set for it. That is also why the Supplement Facts panel prints "Daily Value not established" rather than a percentage — there is no reference intake to measure a serving against. The FDA's page on structure/function claims explains why asterisked statements appear on supplement labels at all, and what the asterisk is required to point to.

The label notes that inositol occurs naturally in both animal and plant foods, so it is a compound most diets already supply in some amount. The form in this bottle is myo-inositol, which the label identifies as the most abundant of the several forms the nutrient takes. Because the panel lists a single ingredient and no blend, there is nothing here to break down further — the 730 mg in a serving is 730 mg of inositol powder and nothing else. For background on how single-nutrient supplements are labeled and compared, the NIH's Dietary Supplement Label Database holds the filed label records for products in this category, and the NIH Office of Dietary Supplements offers a general primer in Dietary Supplements: What You Need To Know.

Supplement Facts

The panel is internally consistent, which is worth noting on a powder: 730 mg multiplied by about 155 servings comes to roughly 113 g, matching the printed net weight. That arithmetic only works because there is genuinely nothing else in the bottle.

How to use it

The label's Suggested Usage reads: take 1/4 level teaspoon daily, dissolved in water or other suitable beverage. That is the whole instruction — one quarter-teaspoon, once a day, mixed rather than swallowed dry. The powder is unflavored, so water, juice or a smoothie all work as carriers.

Measure with a proper measuring spoon rather than a cutlery teaspoon, since the 730 mg figure assumes a level quarter-teaspoon. Store the bottle in a cool, dry place after opening. A freshness packet is enclosed in the bottle; the label warns plainly not to eat it. The label also notes that natural color variation may occur in the product, so a slight difference in shade between bottles is expected rather than a fault.

Why the 4 oz size

At one 1/4-teaspoon serving a day, this bottle is roughly a five-month supply — about 155 servings from 113 g. That suits someone who has already settled on a daily routine and would rather reorder a couple of times a year than every month.

One thing the label flags is worth repeating, because it surprises people who buy powders by size: this product is sold by weight, not volume. Inositol powder is light and settles in transit, so a 4 oz. bottle will not arrive filled to the shoulder. The 113 g on the label is what is weighed in; the space above it is normal. Browse the rest of the Supplements range if a different format suits your routine better.

Who it's for

This is a product for adults 18 and over who specifically want myo-inositol in loose powder form. The powder format is the point of difference: it mixes into a drink, it avoids capsule shells entirely, which matters to buyers avoiding gelatin, and it lets you measure the label's serving with a spoon instead of counting capsules. The Vegetarian/Vegan marking on the front panel makes it usable in plant-based diets, and it sits alongside the rest of our Health & Wellness selection.

It is not a good fit if you want a pre-measured dose you can carry, or a flavored drink mix — this is plain powder in a bottle, measured at home. The label restricts use to adults only.

Good to know

• Allergen statement (as printed): not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients. The same statement adds that the product is produced in a GMP facility that processes other ingredients containing these allergens — a shared-facility note that matters if your sensitivity is severe.
• Caution (as printed): 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.
• Certification: the brand's materials show the Intertek GMP certification mark, an audit of the manufacturing process and laboratory methods. The bottle itself also carries a plain K symbol and a Non-GMO mark.
• Storage: a cool, dry place after opening. Do not eat the enclosed freshness packet.

The NIH National Center for Complementary and Integrative Health keeps a general guide on dietary and herbal supplement safety, which is a reasonable starting point before adding anything new alongside prescription medication.

Frequently Asked Questions

How many servings are in the 4 oz bottle?

About 155 servings, according to the Supplement Facts panel. Each serving is a 1/4 level teaspoon weighing 730 mg, drawn from a net weight of 4 oz. (113 g). Taken once daily as the label directs, that works out to roughly a five-month supply.

Why does the bottle look only part full?

Because the product is sold by weight, not volume — a line printed on the label itself. Inositol powder is light and compacts during shipping, so 113 g of it does not fill a 4 oz. bottle to the top. What the label commits to is the 113 g net weight, not how high the powder sits in the bottle.

Does this powder contain anything besides inositol?

No. The Supplement Facts panel lists inositol powder as the only entry and prints "Other ingredients: None" beneath it. There is no filler, binder, flavoring, sweetener or coloring, and no capsule shell, which is why the serving weight and the ingredient weight are both 730 mg.

Is it suitable for vegans and people avoiding gluten?

Yes on both counts, per the label: the front panel is marked Vegetarian/Vegan, and the allergen statement says the product is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients. Note the same statement's caveat that it is produced in a GMP facility that also processes ingredients containing those allergens.
