Customers say
Customers find this vitamin D supplement to be of good quality and appreciate that it’s easier to take than pills, noting it’s simple to add to food. The product effectively raises vitamin D levels and has powerful immune system effects, with one customer reporting perfect lab results after three months of use. The taste is negligible, and customers consider it a great value. The dispensing mechanism receives mixed feedback – while some prefer the dropper to metered drops, many find it very hard to dispense from.
