    <remarks>I along with the other officers and directors of INVO Bioscience (INVO) were unaware of the individual Form 3,4&amp;5 filing requirements. INVO ran out of funding and stopped reporting to the SEC from 2012 until 2016. During the process of catching up wit the Company's filings in 2017 we learned we needed to file our own individual forms. I am doing that with this Form 5 and the other associated filings all being done at this time. The corporate attorneys of INVO Bioscience's officers and directors. The officers and directors received guidance that it was permissible with the SEC for us to catch up by only filing a Form 5 in each of the years 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016.
On 12/31/2016 I owned 26,155,933 (2015) - 82,811 + 1,000,000 = 27,073,122 restricted shares.</remarks>
