- SAW PALMETTO
Centuries of traditional use. More than a century of scientific research.
Saw palmetto’s use as a therapeutic botanical spans centuries of indigenous knowledge and more than 100 years of clinical investigation. Here is what the science — and our land — can tell you about this extraordinary plant.
Phytochemistry
What’s Inside the Berry
The berries of Sabal serrulata contain a complex mixture of naturally occurring lipophilic compounds, including free fatty acids, phytosterols, long-chain alcohols, and other unsaponifiable constituents. Commercial extracts preserve and concentrate this lipid fraction using solvent or supercritical extraction methods, making fatty acid composition one of the primary measures of extract quality and authenticity.
The following compounds represent the major naturally occurring constituents found in authentic saw palmetto berries and extracts:
Lauric Acid
C₁₂H₂₄O₂ | C12:0 Saturated Fatty Acid
One of the dominant fatty acids naturally present in saw palmetto berries. Lauric acid contributes significantly to the characteristic lipid profile used to identify authentic Sabal serrulata material.
Typically 24–29% of total fatty acid content
Oleic acid
C₁₈H₃₄O₂ | C18:1 Monounsaturated Fatty Acid (Omega-9)
The primary unsaturated fatty acid present in saw palmetto extract. Oleic acid is commonly measured as part of fatty acid profiling used to evaluate extract quality, consistency, and authenticity.
Typically 18–24% of total fatty acid content
Beta-Sitosterol
C₂₉H₅₀O | Phytosterol
The predominant phytosterol found in saw palmetto berries. Beta-sitosterol serves as an important marker compound referenced in quality standards and pharmacopoeial monographs for botanical extracts.
Principal sterol; quantified according to applicable quality standards
Caprylic & Capric Acids
C₈H₁₆O₂ and C₁₀H₂₀O₂ | Medium-Chain Saturated Fatty Acids
These medium-chain fatty acids contribute to the distinctive fatty acid fingerprint of saw palmetto berries and are routinely evaluated during compositional testing.
Combined typically 4–8% of total fatty acid content
Linoleic Acid
C₁₈H₃₂O₂ | C18:2 Polyunsaturated Fatty Acid (Omega-6)
An essential polyunsaturated fatty acid naturally present in saw palmetto berries. Linoleic acid contributes to the characteristic lipid composition used for quality evaluation and authentication.
Typically 18–24% of total fatty acid content
Myristic Acid
C₁₄H₂₈O₂ | C14:0 Saturated Fatty Acid
Present in significant concentrations, myristic acid forms part of the unique fatty acid profile characteristic of authentic saw palmetto berries.
Typically 10–14% of total fatty acid content
Botanical Profile
Sabal serrulata (Michx.) Schult. & Schult. f.
Unlike the tall palms commonly associated with Florida, saw palmetto grows from a branching, creeping stem that often remains partially or completely underground. Over decades, these stems can spread across large areas, producing dense colonies of fan-shaped fronds that have persisted for centuries. Individual stands are remarkably resilient, surviving fire, drought, hurricanes, and changing environmental conditions while continuing to produce fruit year after year.
Each summer, the palms develop clusters of berries that mature from green to yellow, orange, reddish-purple, and finally deep purple-black. These fruits, botanically classified as drupes, are the portion of the plant harvested for commercial use.
Saw palmetto berries are naturally rich in lipophilic compounds, including free fatty acids, phytosterols, and other unsaponifiable constituents. Lauric, oleic, myristic, caprylic, capric, and linoleic acids, along with beta-sitosterol and related sterols, create the characteristic chemical profile used to evaluate authentic saw palmetto material and its extracts.
Florida remains the world’s primary source of wild-harvested saw palmetto berries. The state’s unique combination of climate, sandy soils, and native habitat provides ideal growing conditions, making responsible stewardship of these natural populations essential to the long-term sustainability of the industry.
harvest science
Timing is everything
Saw palmetto berries undergo a gradual maturation process rather than a simple transition from unripe to ripe. As the fruit develops through the late-summer season, its chemical composition continues to evolve, making harvest timing an important factor in overall berry quality.
Our harvest windows are determined through field observation and maturity assessments rather than fixed calendar dates. Experienced crew leaders monitor berry color progression—from green to yellow-green, golden-yellow, and ultimately deep purple-black—along with fruit condition across multiple harvest areas. Individual stands are harvested when they reach their optimal stage of maturity.
Berries are harvested by hand to help minimize bruising and maintain fruit quality during collection and transport. Following harvest, berries are delivered to our sorting facility and transferred to temperature-controlled drying as quickly as possible to support product consistency and preserve naturally occurring compounds.
By combining careful harvest timing with prompt post-harvest handling, we are able to produce consistently high-quality material that meets the standards expected by manufacturers and ingredient buyers.
