Total retail sales of herbal dietary supplements in the United States increased by an estimated 6.8% in 2014 marking the 11th consecutive year of growth. This increase is slightly less than 2013s 7.9% increase, which was the greatest percentage sales jump since the late 1990s.1 Sales of herbal supplements have been increasing steadily since 2002-2003 when the market experienced a brief, two-year dip in total sales (Figure 1 and Table 1). Last year, American consumers spent roughly $6.4 billion on herbal supplements over $1 billion more than was spent in 2011 and $400 million more than 2013 according to aggregated market statistics provided by the Nutrition Business Journal (NBJ).

The data in this report correspond to retail sales of herbal supplements in three distinct market channels mainstream, natural, and direct sales (Table 2) as defined by NBJ and the Chicago area-based market research firms SPINS LLC and IRI (Information Resources, Inc.). Herbal supplement sales estimates do not include herbal teas, plant-based natural cosmetic products (cosmeceuticals), or over-the-counter (OTC) medications with US Food and Drug Administration (FDA)-approved botanical ingredients such as psyllium (Plantago ovata, Plantaginaceae) or slippery elm bark (Ulmus rubra, Ulmaceae).

In 2014, for the sixth year in a row, sales increased in each of these three channels (Table 3). Herbal supplement sales from natural and health food stores experienced the strongest estimated growth of 7.7%, while mainstream and direct sales increased by 5.0% and 6.7%, respectively, from the previous year.

Mainstream Retail Channel

Sales of herbal dietary supplements in the mainstream channel alone totaled $815,970,645 in 2014, as determined by SPINS and IRI. This figure represents a 2.1% increase over 2013 sales in this channel, which totaled just under $800 million (Table 4). NBJ which includes convenience store data in its mass-market channel estimated slightly higher sales of $1.12 billion.

Since 2013, SPINS and IRI have collaborated to produce a combined data set for mainstream retail sales; previously, HerbalGram included separate tables that reflected the firms different methods for coding herbal products. (The SPINS-IRI collaboration resulted in a restatement of previously published 2013 and 2014 sales. Though the data are identical in most cases, small discrepancies remain, as some of the sales figures are sometimes modified subsequent to their initial publication. Year-over-year trends should be referenced within the same published report.)

Horehound was the top-selling herbal dietary supplement in mainstream outlets for the second year in a row with sales of $105,880,497 almost twice that of the second top-selling herb, cranberry. Traditionally, horehound has been used as an expectorant and to treat respiratory symptoms, often in the form of a bitter tea2; today, the herb is commonly found in multi-herbal combination lozenges (e.g., Ricola® Natural Herb Cough Drops).

Many popular and well-known botanicals kept their place on 2014s list of top-selling herbal supplements in mainstream retail outlets. Ginkgo, garlic, valerian, and milk thistle ranked among the 20 top-selling herbs; total sales for these supplements were also some of the least changed from 2013 suggesting their continued mainstream acceptance.

Several herbs experienced significant sales increases in 2014. For the first time, ivy leaf made HerbalGrams top-40 list in the mainstream market channel with estimated total sales of $8,086,029 a whopping 379% increase from 2013. The German Commission E approved ivy leaf for the treatment of respiratory inflammation, and the herb has been a popular component of cough-relieving formulas in Europe for years.3 (According to Pizzorno and Murrays Textbook of Natural Medicine,4more than 80% of herbal expectorants prescribed in Germany [in 2007] comprised ivy extract.) Although the authors of a 2010 systematic review5 concluded that there was no convincing evidence that ivy leaf is effective for treating upper respiratory tract infections, at least two recent studies6,7 have suggested that the herb may be beneficial for respiratory conditions in children under the age of 12. According to SPINS, the ivy leaf product with the highest mainstream sales in 2014 was, in fact, a pediatric formulation.

In addition to ivy leaf, three other botanicals were new to 2014s list of 40 top-selling herbal supplements in the mainstream channel. Sales of rhodiola, guarana, and grass (wheat or barley) supplements earned these herbs rankings of 15th, 21st, and 40th, respectively. These products replaced bromelain, artichoke, slippery elm, and acai, each of which was on 2013s list of 40 top-selling herbs in this channel. 

Coconut oil continues to enjoy booming sales in the mainstream channel. Mass-market retailers sold an estimated $9,239,429 of the botanical product in 2014, a remarkable 210% jump from the previous year. The increased sales were enough to make coconut oil the 22nd top-selling herb in 2014 in the mainstream channel, up significantly from its ranking of 40th in 2013. Dr. Mehmet Oz, MD, first touted the health benefits of this miracle fat that fights fat in 2012 on his daytime television program,8 claiming that the product can help with weight loss, skin conditions, and ulcers. Rich in saturated fat and medium-chain triglycerides, coconut oil became even more popular in 2013 when adopters of the Paleo diet which encourages the consumption of so-called healthy fats embraced the product. In 2014, celebrity endorsements9 of coconut oil for oil pulling (an Ayurvedic folk tradition in which oil is swished around the mouth to improve oral and general health) helped increase its visibility once again. Despite popular claims that coconut oil has benefits ranging from teeth-whitening to heart disease risk reduction, there are few high-quality scientific studies that support such assertions.10-12

Compared to 2013 data, total mainstream channel sales increased significantly for a number of other herbs including fenugreek (+85%), echinacea (+79%), elderberry (+64%), and turmeric (+60%). Mainstream echinacea sales in 2014 resulted in the herb moving from the 8th top-selling herb in 2013 to the 3rd top-selling in 2014; increased sales of fenugreek bumped the supplements ranking from #36 to #28 in the same time period.

Two plant-derived compounds saw mainstream sales increases in 2014 as well. Sales of plant sterols in 2014 increased 33% from the previous year, and bioflavonoid supplement sales increased by 21%. However, sales of isoflavones the only other isolated plant compound-based supplement on the list resulted in the largest percentage decrease (-29%) of any of the 40 top-selling products in the mainstream channel.

Other notable sales declines in 2014 include kelp (-26%), rhodiola (-20%), horsetail (-20%), and tribulus (-20%).

Sales figures for the categories Chinese herbs and whole food concentrate were not included in HerbalGrams top-40 mainstream channel rankings due to their relative broadness. Had they remained on the list, Chinese herbs would have been the 2nd top-selling supplement and whole food concentrate would have ranked 39th in this channel. Individual formulations not primarily derived from botanicals such as biotin, a B vitamin found in some plants, and beta glucans, derived from yeast also were excluded. As the only branded supplement on the list, Relora ® (Next Pharmaceuticals, Salinas, California; purchased by InterHealth Nutraceuticals Inc., Benicia, CA), a proprietary blend of magnolia (Magnolia officinalis, Magnoliaceae) and phellodendron (Phellodendron amurense, Rutaceae) bark extracts, was removed as well.

Natural Channel

The natural channel saw a 5.2% increase to $330,088,019 in estimated total sales over 2013 (Table 5), a healthy yet significantly smaller gain compared to 2013s 9.9% increase1 and 2012s impressive 14.7% increase.13 (These data do not include sales from Whole Foods Market, which does not report its supplement sales to market tracking firms.) Sales in the natural channel tend to come from what marketers call core shoppers, who are committed to a more natural lifestyle, including natural-health modalities. So-called peripheral shoppers, who have less of a personal commitment to a natural-health philosophy, are more likely to purchase dietary supplements in the mainstream channel.

Consumers in the natural channel also are showing an increasing interest in issues of transparency, traceability, and sustainability, often choosing supplements that are ethically sourced, organically grown or wild-crafted, part of a fair trade initiative, etc.

After taking the first slot in the natural channel in 2013, turmeric sales remained strong with an almost 31% increase, totaling $26,288,705 in 2014. This is a continued increase from 2013, in which turmeric saw 26.2% growth in the natural channel. Recent research on turmeric and its primary active constituent curcumin garnered a great amount of attention, with a growing list of purported benefits. PubMed, the research database run by the National Center for Biotechnology Information (part of the National Institutes of Health), lists almost 8,000 studies on curcumin as of July 2015.14 Originally gaining interest for its anti-inflammatory effects as a natural COX-2 inhibitor, turmeric and curcumin currently are being investigated for their cancer-fighting properties,15 protection against heavy metal toxicity,16 and relief of symptoms of depression,17 among many other potential uses.

The top 20 herbs in the natural channel remained the same from 2013, though some swapped rankings. Maca and oregano showed high growth at 15.2% and 12.4%, respectively; stevia, now a popular non-caloric sweetener, saw the largest drop of 12.3%. (Sales of stevia as a supplement do not reflect sales of stevia as a food product and use as a sugar alternative; previously, before the FDA approved stevia as a safe food ingredient, it was sold legally in the United States only as a dietary supplement.)

Macas popularity in 2014 surprised the Peruvian farmers that cultivate the crop, and increasing demand from both the United States and China caused the price for fresh and dried maca to skyrocket. The adaptogenic herb is prized for its use against aging, declining sexual health, and depression, and allegations of biopiracy and Chinese maca smuggling has been reported.18 Despite high prices and suspected adulteration, Peruvian-sourced maca continues to draw consumers.

Oregano supplements, which SPINS defines as oregano essential oil and supplements as well as oregano leaf tinctures, experienced double-digit growth in 2014. Marketers claim that oregano supports the immune system and has antifungal, antibacterial, and antiviral properties. In late September 2014, the FDA issued warning letters to several companies that made exaggerated and unsubstantiated claims regarding their oregano oils in regards to the Ebola virus epidemic.19

Direct Sales

In 2014, the direct sales channel saw a growth of 6.7%, or almost $200 million more than 2013. Direct channel sales of herbal dietary supplements include multi-level marketing companies (also known as network marketing companies) such as Advocare, Herbalife, Natures Sunshine, Nu Skin/Pharmanex, Nutrilite (Amway), Shaklee, USANA, and similar competitors. This channel also encompasses mail and Internet order sales companies, direct response TV and radio sales, and sales by health practitioners.

Single vs. Combination Supplements Sales

According to NBJ, sales of single-herb dietary supplements in all channels increased by 4.4%, and sales of combination formulas rose 10.7% (Table 6). Combination formulas generally use a blend of herbs that are marketed for a specific benefit, including maintaining healthy blood sugar and/or blood lipid levels, and easing the effects of menopause, among others. As shown in Table 6, herbal combination supplements have been growing in popularity for the past few years, consisting of 36.2% of total herb sales in 2012 and currently representing 39.2% of sales. Consumer knowledge of herbs and their benefits continues to become more sophisticated, and as sales of whole herb preparations maintain their growth, a more educated population emerges. Consumer awareness of the benefits of whole herbs versus their isolated constituents may also play a role in the increasing sales for combination supplements. Herbal blends, such as those used in traditional Chinese medicine, have a long history of traditional use and modern research continues to explore their efficacy.20,21


For the 11th consecutive year, American consumers spent more on herbal dietary supplements than they did in the previous year. Since 2011, estimated herbal supplement sales in all channels have increased by more than $1 billion; in 2014, US consumers spent roughly $400 million more on plant-based supplements than in 2013. These figures suggest a clear trend: Americans are continuing to rely on botanical products for various aspects of their wellbeing and other personal needs.

The sales data presented in this report reflect consumer preferences that are similar to those of previous years. In 2014, retail sales of combination herbal supplements and total supplement sales in natural and health food stores increased faster than other herbal supplement products and channels, respectively.

Despite more than a decade of increased total annual sales of herbal dietary supplements, some members of the natural products community have expressed concern that 2015 sales could be impacted by recent negative press surrounding herbal products namely, the New York Attorney Generals herbal supplement investigation that began in February 2015.22 However, as detailed in a recent NutraIngredients-USA article,23 SPINS data show that sales of herbal formula (combination) supplements for the 52 weeks ending in mid-July 2015 are up 12.6% from the same period a year earlier. Interestingly, single-herb supplements have not fared as well. Total sales, calculated by SPINS in four-week segments, increased for single-herb products until March 22, but since then, sales of these products have steadily declined. Still, overall sales of herbal monopreparations in the US remained fairly constant between mid-July 2014 and mid-July 2015, with a total increase of just 1.1%.
