Pregnancy Home > PreferaOB Dosage

Although PreferaOB should be taken every day, do not worry too much if you occasionally miss a dose. PreferaOB comes in three different products, and the dosage your healthcare provider prescribes will depend on the particular product you are using. Taking this vitamin with food may help minimize nausea and stomach upset.

An Introduction to Dosing With PreferaOB

Your dose of PreferaOB® vitamins may vary, depending on the particular product you are using. As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

What Is the Recommended PreferaOB Dosage?

The usual recommended dosage of PreferaOB is one vitamin/mineral tablet taken once a day. For PreferaOB+DHA™, the usual recommended dose is one vitamin/tablet (the same vitamin and mineral tablet found in PreferaOB) and one softgel, which contains docosahexaenoic acid, also known as DHA. PreferaOB ONE™ is taken once a day and comes as a single softgel, which contains the vitamins, minerals, and DHA all in one capsule.
You should try to remember to take these vitamins every day. However, do not worry too much if you occasionally miss a dose.
