Matthew T. Farrell
President and Chief Executive Officer at Church & Dwight
Okay. Good morning everyone. Thanks for joining us today. I'll begin with a review of the Q1 results. And then I'll turn the call over to Rick Dierker our CFO. And when Rick is done, we'll open the call for questions. Q1 was a solid quarter for us. Reported revenue was up 4.7%, organic sales grew 2.7%, and we exceeded our 1% to 2% Q1 outlook for organic growth. The adjusted EPS was $0.83 and that's $0.08 better than our outlook. We grew consumption in 11 of the 17 categories in which we compete and in some cases on top of big consumption gains last year. This is remarkable as our low fill rates held back our consumption. The good news is April fill rates across many categories are now mid to high 80s and improving.
Regarding brand performance our brands saw a double-digit consumption growth in seven of those categories and I'll name them for you. ARM & HAMMER Scent Boosters, ARM & HAMMER Baking Soda, ARM & HAMMER Clumping Litter, BATISTE dry shampoo, WATERPIK, Water Flossers, ZICAM zinc supplements, and THERABREATH mouthwash. In Q1 online sales as a percentage of total sales was 16%. Our online sales increased 2.6% year-over-year. Now, keep in mind, this is on top of 53% growth in e-commerce that we experienced last year in Q1 versus 2020. We continue to expect online sales for the full year to be above 15% as a percentage of total sales.
Now, since early 2021 we have announced price increases to combat inflation. And through early 2022, we had already announced price increases covering 80% of our global portfolio. Since we spoke to you last in January, we are now expecting $85 million of new incremental cost inflation. And as a result we recently announced another round of price increases on our Fabric Care and Litter products which will be effective in July of this year. In addition to pricing we are pursuing additional measures to offset higher-than-expected costs such as productivity and pack size changes. Also in laundry you may know we have now concentrated our portfolio by approximately 10%. Now, I'm going to talk about each business and first up is the Consumer business in the US. Consumer Domestic business grew organic sales 2.7% and this is on top of 5.1% organic growth in Q1 of 2021. Looking at market shares in Q1, seven of our 14 power brands gained share.
Our most recent acquisitions are performing well. THERABREATH, which we acquired in December of 2021, had a great quarter with 37% consumption growth. THERABREATH grew share of 3.6 points to 15% of the alcohol-free mouthwash category and Q1 was the first full quarter in which THERABREATH surpassed ACT as the fourth largest mouthwash brand and THERABREATH remains the number two alcohol-free mouthwash brand. Total distribution points or TDPs as we call them for the THERABREATH brand are up 20% versus a year ago. ZICAM also delivered strong results this quarter. You may recall we acquired ZICAM at December of 2020. We were hurt in year one of our ownership due to masking and social distancing. ZICAM cold remedy consumption was up 56% in Q1 and we expanded our share of the cold shortening segment to a little over 75% share.
Turning to Gummy Vitamins. Total shipments of VITAFUSION and L'IL CRITTERS were relatively flat in the quarter. Demand for gummies remained high as the category consumption grew 11% but our case fill was low. So, we left money on the table in Q1. The good news is our fill rates also in vitamins are finally starting to improve. Next up is International. Despite significant disruptions, our International business did deliver some organic growth in Q1 0.3%, primarily driven by STERIMAR, BATISTE, OXICLEAN, and VMS in the Global Markets Group. Lockdowns and transportation issues hurt our results. We have the orders we're just struggling to fill them. We expect our difficulties to abate in the second half in International. Next up is Specialty Products. Our Specialty Products business delivered a strong quarter with 9.2% organic growth driven by both higher pricing and volume.
I want to spend a few minutes on the health of the consumer private label trends innovation and our ability to supply. Now, we all know that inflation is at a multi-decade high interest rates are rising to tamp down inflation. And while wages have risen households are getting squeezed and we expect consumers will start to make choices to make their dollars go further. We have seen Netflix lose subscribers, but here are a few indicators that we're seeing. First, consumption of value detergent was flat year-over-year in Q1 and this is after losing share to premium detergent for several quarters. Over in Cat Litter, our traditional ARM & HAMMER orange box Cat Litter which is a value product, grew faster than our premium ARM & HAMMER Cat Litter in Q1.
Over in Personal Care, WATERPIK is seeing faster growth of lower priced price point models in the flosser business. And then in showerhead, showerhead category consumption is slowing which may be an indicator that consumers may be spending less on home improvement. Now, we're keeping an eye on these trends and we are prepared if categories become more promotional in the second half. It's important to point out that 40% of our portfolio is valued and we expect to perform well in a difficult economic environment. And just to remind everyone, our largest businesses -- larger detergent and vitamins are value products. And in litter, our orange box is also valued. So we feel well positioned for what may be coming.
Now regarding private label. Private label shares are stable in the five categories, where we have meaningful exposure to store brands. As you saw in the release, we have a strong lineup of innovation across our personal care and household categories. Most of these new products are shipping in Q2 and we believe our consumer is always attracted to new and improved product offerings. Regarding our ability to supply, we hit bottom early in Q1 with the Omicron resurgence and we saw our fill rates dip below 80%. As I mentioned earlier, April fill rates are trending toward the mid-to-high 80s and we're on track to be at historical fill levels by the end of the year. So we have confidence in our full year outlook for several reasons. We have improving fill rates. We have new product innovation hitting the shelves by July 1. Two-thirds of our marketing spend is concentrated in the second half. We have the incremental impact of pricing and we have the positive effect of concentration consumption. So in closing, we expect our portfolio of brands to do well, both in good and bad times and we continue to hunt for new TSR-accretive businesses.
And next up, is Rick to give you more details on Q1.
