        FAQs
        What is the difference between Essentia, Solo, and Companion?
        Theralogix offers three different multivitamins to meet your nutrient needs at different life stages.

        Essentia is a comprehensive multivitamin designed for women that provides methylated folate, vitamin C, B vitamins, 50 mg of choline, 50 mcg (2,000 IU) of vitamin D3, and 18 mg of iron, along with chelated minerals and other essential nutrients. Essentia is recommend for younger women or any adult who needs iron in their daily multivitamin.

        Solo is a well-balanced multivitamin that provides methylated folate, vitamin C, B vitamins, 50 mg of choline, and 50 mcg (2,000 IU) of vitamin D3, along with chelated minerals and other essential nutrients. Solo does not contain iron, so it’s recommended for men, women 51+, or any adult who does not need iron in their daily multivitamin.

        Companion does not contain iron, vitamin D, or vitamin K. It is recommended for adults already taking a supplement with adequate vitamin D, as well as those advised to limit vitamin K intake or who do not need supplemental iron.

As with any dietary supplement, discuss with your pharmacist and/or healthcare team to determine whether Companion can be taken with your medications.

        Antibiotics: Taking calcium, magnesium, and/or zinc (in Solo) along with antibiotics can decrease their absorption and effectiveness. Depending on which antibiotic is prescribed, you may need to separate Companion from the antibiotic, as indicated below.

        Thyroid hormone (levothyroxine, Synthroid): Minerals in Companion can reduce absorption of these medications. Separate Companion and thyroid hormone by at least 4 hours. 

        Medications for overactive thyroid (methimazole, propylthiouracil): Taking iodine (in Companion) along with these medications might change their effects. Consult with your healthcare provider if you’re taking medication for an overactive thyroid along with Companion.
