Thank you, Vanessa. Total revenue for the fourth quarter of 2016 was $6.3 million compared to $4.3 million for the corresponding period in 2015. The 47% increase was driven by a 46% increase in international revenues as a result of our Swedish distribution partner People's Choice moving towards a more normalized ordering pattern and shipments as well as the shipment of our initial launch order to Yeo's located in Singapore.
Domestic revenue, which also grew, was up 46% for the fourth quarter of 2016. This continued double-digit domestic growth rate was derived from blended growth rates on a 53% growth from retail accounts, a 47% growth from health and fitness accounts, and a 12% growth from internet retailers.
Gross profit for the quarter was a $2.6 million or 41% of revenues, compared to $1.7 million or 39.1% of revenues for the corresponding period last year. This 190 basis point improvement in margin was driven by our continued focus on improving promotional allowances and our continued focus on implementing cost of good reductions.
Operating expenses in the fourth quarter of 2016 increased $306,000 to roughly $3 million, up from $2.7 million on the prior year. This increase was associated with an increase of a roughly about $350,000 in general and administrative expenses, driven by higher option expense, increased administrative fees, primarily from legal, which was partially offset by lower marketing expenses, driven by our shift of focus toward increased use of social media outlets and lower utilization of digital and print media during the quarter.
Total other expense was $51,000 for the fourth quarter of 2016 compared to $58,000 for the fourth quarter in 2015. Net loss to common shareholders for the fourth quarter of 2016 was $510,000 or a loss of $0.01 per share compared to a net loss of $1.3 million or $0.03 per share basic and diluted for the corresponding period last year.
Operating expenses for the quarter including noncash expense, including depreciation, amortization and stock-based compensation, which totaled approximately $370,000 compared to $405,000 the prior year.
Adjusted EBITDA for the quarter was a negative $140,000 compared to a negative adjusted EBITDA of $890,000 the corresponding period in 2015. We believe, this information concerning adjusted EBITDA, a non-GAAP financial measure, enhances our overall understanding of our financial performance. A reconciliation of our GAAP results to this non-GAAP measure was included in our earnings press release.
Now moving to our 2016 annual results. Total revenue for 2016 was a record $22.8 million compared with $17.2 million in 2015. This 32% increase was primarily driven by a 59% increase in domestic revenues and a 4% increase in international revenues. Domestic revenue growth for the full year was driven by double-digit revenue growth across each of our distribution channels. This continued double-digit domestic revenue growth was derived from blended growth rates of a 70% growth from retail accounts, where we're experiencing double-digit growth rates in existing accounts as well as our continued expansion into the convenience store channel with our initial emplacement which took place in 7-Eleven in early 2016.
Our health and fitness accounts continue to perform well, growing 51% versus the prior year, led by strong growth from existing accounts and expansion regional and national chains as well as a recent expansion into the Army and Air Force bases globally.
In addition, our Internet retailer accounts, mainly derived from Amazon, continue to perform well and grew 26% versus the prior year. International revenue growth was primarily result of our Swedish distribution partner returning to more normalized ordering patterns in the second half of 2016. Gross profit for the full year of 2016 was a record $9.7 million or 42.7% of revenues, compared with $7 million or 40.9% of revenues for the corresponding period last year. A 180 basis point improvement in gross profit margin was the result of continued focus on improving promotional allowances and implementing our -- and reducing our cost of goods.
Operating expenses for the full year 2016 was $12.6 million, up from $8.9 million from the prior year. The increase was due primarily to increases in investments in marketing programs, which increased $1.2 million as well as investments in sales employee cost, roughly around $1.5 million and other related sales expense of $360,000. In addition to -- administrative expenses increase, $730,000, was mainly the result of increases in professional fees, investor relations, increases in human resources and travel-related expenses. Total other expense for the full year 2016 decreased to $223,000 from $322,000 in the prior year as a result of lower interest expense.
Net loss to common shareholders for the full year 2016 was $3.4 million or $0.09 per share basic and diluted, compared to a net loss of $2.6 million or $0.08 per share basic and diluted for the full year of 2015.
Net losses or the losses attributed to common shareholders are inclusive of preferred dividends. For the full year of -- full year ending December 31, 2016, and 2015. The net losses included preferred dividends of $366,000 and $421,000, (sic) [ $420,000 ] respectively.
Operating expenses for the full year 2016 included noncash expense, including depreciation, amortization and stock-based compensation, which totaled approximately $2.2 million compared to $2 million in the prior year. Adjusted EBITDA for the full year of 2016 was a negative $1.2 million compared to a negative adjusted EBITDA of $524,000 for the full year in 2015.
Turning to the balance sheet. As of December 31, 2016, the company had cash and cash equivalents of $11.7 million and working capital of $15.4 million. At this time, we believe, our current cash balance with the inclusion of our recent strategic investment will sufficiently meet our needs as -- cash needs as anticipated over the next 12 months. Cash used in operations for the full year 2016 totaled $2.4 million compared to cash used in operations of $755,000 in 2015.
That concludes our prepared remarks. Operator, you may now open the call for questions, thank you.
