Many users report improved energy levels, better overall health, and specific benefits such as enhanced cardiovascular health, muscle tone, and nervous system support. The product is praised for its easy-to-swallow capsule size and convenient packaging. However, some customers noted an unpleasant smell and a side effect of bright yellow urine.

all types of vitamin B in just one capsule
Verified purchase
I'm glad to have all types of vitamin B in one capsule. The pills are yellow in color, with a slight smell specific to this type of vitamin, they are easy to swallow and bring a lot of benefits. The most important thing is that it is administered only 1 per day.

Clean quality Vit B
Verified purchase
I like that Natural Factor generally offers cleaner ingredients. It is good in size n potent for the nervous system. The size of the pill is ok as well. Most importantly as most Vit B supplements come in unbearable taste, this brand is easier to handle than those I have tried so far.
