NOW Glucomannan 575 mg: konjac root fibre in veg capsules
NOW Glucomannan gives 575 mg of glucomannan per vegetarian capsule, a soluble fibre from konjac root (Amorphophallus konjac). A serving of 3 capsules provides 1,725 mg of glucomannan and 2 g of dietary fibre for about 5 calories, and the bottle holds 180 capsules, 60 servings. Glucomannan absorbs water and forms a thick gel, so it is taken 30 to 45 minutes before a meal with a large glass of water. It suits adults on a calorie-controlled meal plan who want to add soluble fibre before meals, as a capsule rather than konjac noodles or jelly. It does not replace a balanced diet and regular activity.

How to use
Adults: take 3 capsules with at least 240 ml of water 30 to 45 minutes before a meal, once or twice a day. Swallow each serving with at least a full glass (240 ml) of water: without enough liquid the capsules can swell in the throat and cause choking.

Store in a cool, dry place after opening and don’t eat the freshness packet.

NOW Glucomannan questions
What is glucomannan?
Glucomannan is a soluble fibre from the root of the konjac plant (Amorphophallus konjac). It absorbs a lot of water and forms a thick gel, which is why it is taken before meals with a large glass of water.
How much glucomannan is in a serving?
3 capsules give 1,725 mg of glucomannan and 2 g of dietary fibre for about 5 calories. The bottle of 180 capsules holds 60 servings, 30 to 60 days depending on whether you take one or two servings a day.
How do I take NOW Glucomannan?
Take 3 capsules with at least 240 ml of water 30 to 45 minutes before a meal, once or twice a day. Swallow each serving with at least a full glass (240 ml) of water: without enough liquid the capsules can swell in the throat and cause choking. Don’t use it if you have ever had a narrowed oesophagus or trouble swallowing, and don’t take it just before bed.
Can I take it with my medication?
Fibre can slow how some medication is absorbed, so take medication at least an hour before or a few hours after glucomannan, and check with your doctor or pharmacist first, especially if you take medication for blood glucose.
Is it vegetarian?
Yes, the label says vegetarian/vegan and the capsules are plant cellulose. It is for adults only and does not replace a balanced diet and regular activity. Food supplements don’t replace a varied diet. If you’re pregnant, breastfeeding, under 18, taking medication or have a medical condition, ask your doctor first.
