“As per nutrition information 5g of psyllium contains 4.1 grams of fibre but only 0.1g carb

Fiber supplements, such as those made from psyllium or bran, can help increase your fiber intake when you’re consuming a high-protein, low-carb diet. Some psyllium fiber supplements are carb-free, but contain up to 15 grams of fiber per tablespoon. Consult with your physician before taking any type of supplements, including fiber supplements.

IMPORTANT If you take too much, say two tablespoon in only one glass of water. And you do not drink enough water after that, you can become severely constipated, as the Psyllium bulk becomes hard due to a lack of water and blocks the colon.

The bulk fiber of Psyllium will move out whatever is in the intestines, including the good bacteria. If the healthy bacteria are not replaced with probiotics, you are going to have gas production and feel bloated. It is a good idea to take probiotics daily.” - https://www.fatsecret.com.au/calories-nutrition/macro/psyllium-husk/1-tbsp
