#### Supplement dated February 16, 2023

#### to the Statement of Additional Information ("SAI") dated May 2, 2022

*Capitalized terms and certain other terms used in this supplement, unless otherwise defined in this supplement, have the meanings assigned to them in the SAI.*

Effective February 21, 2023, the SAI is amended as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The fourth paragraph on page 58 of the SAI, under the heading "Disclosure of Portfolio Holdings," is deleted in its entirety and replaced with the following:

Except for the NVIT Jacobs Levy Large Cap Growth Fund and NVIT Jacobs Levy Large Cap Core Fund, each Fund posts onto the Trust's internet site (nationwide.com/mutualfundsnvit) substantially all of its securities holdings as of the end of each month. Such portfolio holdings are available no earlier than 15 calendar days after the end of the previous month, and generally remain available on the internet site until the Fund files its next portfolio holdings report on Form N-CSR or Form N-PORT with the SEC. The NVIT Government Money Market Fund posts onto the Trust's internet site, no later than the fifth business day of each month, a schedule of its investments as of the last business day or subsequent calendar day of the prior month and maintains such portfolio holdings information for no less than six months after posting. All Funds (including the NVIT Jacobs Levy Large Cap Growth Fund and NVIT Jacobs Levy Large Cap Core Fund), disclose their complete portfolio holdings information to the SEC using Form N-PORT within 60 days of the end of the third month of the first and third quarters of the Funds' fiscal year and on Form N-CSR on the second and fourth quarters of the Funds' fiscal year. The NVIT Government Money Market Fund discloses its complete portfolio holdings information to the SEC on Form N-CSR and files monthly reports using Form N-MFP. Shareholders receive either complete portfolio holdings information or summaries of Fund portfolio holdings with their annual and semiannual reports.
