Acer saccharum (Sugar Maple Sap)
Preliminary EvidenceCompound
Hermetica Superfood Encyclopedia
Sugar maple sap is a clear liquid extracted from Acer saccharum trees, primarily composed of sucrose (>98% of carbohydrate content) along with trace minerals. The sap provides simple carbohydrates for immediate energy and delivers bioavailable minerals including potassium (26-75 ppm) and calcium (8-56 ppm).
Acer saccharum, or Sugar Maple Sap, is the raw, dilute liquid tapped from sugar maple trees native to northeastern North America. Harvested in late winter and early spring, this sap contains approximately 2-3% sucrose and is the precursor to maple syrup, which is produced by boiling and concentrating the raw sap [1, 2].
No human clinical trials, randomized controlled trials (RCTs), or meta-analyses for sugar maple sap were identified in the research. The existing scientific literature is preclinical, focusing on compositional analysis, such as metabolomics studies of sap (e.g., PMID 32817615), and in vitro experiments on processed syrup extracts [1, 4].
No clinically studied dosage ranges exist for sugar maple sap or its derivatives in any form, as human trials are absent. Consult a healthcare provider before starting any new supplement.
Sugar maple sap is a dilute aqueous solution (~96-98% water) with 2-4°Brix (2-4% dissolved solids). **Carbohydrates:** Predominantly sucrose at ~20-40 g/L (>98% of total sugars), with trace amounts of glucose and fructose (<1 g/L each); invert sugars increase with season progression. **Minerals (per liter of raw sap):** Potassium 26-75 mg, Calcium 8-56 mg, Magnesium 1.5-10 mg, Manganese 0.2-6.8 mg, Zinc 0.3-2.0 mg, Sodium 0.5-3.0 mg, Iron 0.1-0.8 mg, Phosphorus 0.5-3.0 mg. Mineral content varies significantly with tree health, soil composition, and seasonal timing. **Organic Acids:** Malic acid (predominant, ~2-6 mg/L), citric acid, succinic acid, and fumaric acid in trace amounts; these contribute to a mildly acidic pH of ~5.2-7.3. **Amino Acids:** Total free amino acids ~1-10 mg/L, including arginine, glutamic acid, alanine, and proline in small quantities. **Phenolic Compounds:** Total phenolics approximately 1-5 mg GAE/L in fresh sap (substantially lower than in concentrated syrup); includes lignans (e.g., syringaresinol, lirioresinol), flavonoids (trace catechin, epicatechin), and phenolic acids (gallic acid, vanillic acid, syringic acid) at sub-mg/L levels. Quebecol is formed during thermal processing and is not present in raw sap. **Abscisic Acid (ABA):** Detected at trace phytohormone levels (~nanogram range); bioavailability and physiological relevance at these concentrations in humans is undetermined. **Vitamins:** Negligible; trace amounts of B-vitamins (riboflavin, niacin) have been reported but are not nutritionally significant per serving. **Protein/Fat/Fiber:** Essentially zero protein (<0.01%), zero fat, and zero dietary fiber. **Caloric Value:** Approximately 8-16 kcal per 250 mL serving (from sucrose content). **Bioavailability Notes:** Minerals are present in ionic/soluble form, suggesting reasonable bioavailability, though absolute quantities per serving are nutritionally minor (e.g., potassium provides <2% of daily adequate intake per 250 mL). Phenolic compounds are present at concentrations far below those used in in vitro bioactivity studies; their bioavailability and health relevance at sap-level concentrations have not been established in human trials. The concentration factor from sap to syrup (~40:1) means that syrup is a far more concentrated source of all non-water constituents.
Sugar maple sap delivers rapid glucose availability through sucrose hydrolysis by intestinal sucrase enzymes, providing immediate cellular energy via glycolysis. The naturally occurring minerals, particularly potassium, support electrolyte balance and cellular membrane potential maintenance. The bioactive compounds facilitate mineral absorption through natural chelation processes inherent in the plant matrix.
Current evidence for sugar maple sap is limited to compositional analysis rather than controlled human trials. Studies have characterized the mineral content, showing consistent levels of potassium (26-75 ppm) and calcium (8-56 ppm), but no clinical trials have evaluated health outcomes. The sucrose content (>98% of carbohydrates) is well-documented through analytical studies. Evidence strength remains preliminary due to lack of interventional research on health benefits.
Sugar maple sap is generally recognized as safe when consumed as a food product with no documented serious adverse effects. Individuals with diabetes should monitor blood glucose levels due to the high sucrose content. No significant drug interactions have been reported, though the simple sugar content may affect blood sugar medications. Pregnant and breastfeeding women can safely consume sugar maple sap as part of a normal diet.
