SAC can serve as a stable standardization anchor within a broader aged-garlic organosulfur matrix, matching the material context used in most human trials.
Evidence: Human evidence is for standardized aged-garlic extracts, not purified SAC; equivalence requires compositional and exposure bridging.Source
The pairing can support a complementary cardiovascular and oxidative-stress formulation concept using water-soluble SAC and lipophilic CoQ10 in a multi-unit capsule or tablet system.
Evidence: Formulation rationale only; no direct human trial proving purified SAC–CoQ10 synergy was identified.
Literature-Supported Research Directions
After consumption of a garlic supplement containing SAC, human pharmacokinetic work found rapid gastrointestinal absorption with a half-life above 10 hours and excretion extending beyond 30 hours. The study used a garlic supplement matrix rather than isolated SAC alone.

A 12-week randomized placebo-controlled trial in 50 patients tested aged-garlic extract capsules providing 2.4 mg/day SAC and reported lower systolic blood pressure in the subgroup with uncontrolled hypertension. The result belongs to the complete extract, not isolated SAC.

A randomized crossover trial in 67 adults with moderate hypercholesterolemia used one tablet daily of black-garlic extract standardized to 1.25 mg SAC and reported a decrease in diastolic blood pressure, especially in a male subgroup. The intervention contained a complete extract and subgroup interpretation requires caution.

S-Allyl-L-cysteine is a water-soluble organosulfur compound used as a characteristic constituent and standardization marker of aged-garlic supplements sold in capsules and tablets. Pure-SAC formulations must not inherit clinical claims from whole aged-garlic extract without bridging evidence.
This page is for S-Allyl-L-Cysteine (SAC), CAS 21593-77-1. It is not the same product page as S1PC, which is listed separately under CAS 52438-09-2. Buyers should use the CAS number and structural identity when qualifying the material.
Batch PGSAC-260520 reports 99.4% purity by HPLC against a specification of ≥98%.
The COA includes ethanol residue, heavy metals, lead, mercury, cadmium, arsenic, sulfate, iron, chloride and total plate count. The referenced batch reports ethanol residue of 0.08% and loss on drying of 0.09%.
SAC is supplied as S-Allyl-L-Cysteine, CAS 21593-77-1, formula C6H11NO3S, molecular weight 177.22 g/mol. The lot-specific COA should be used for final identity and purity qualification.
SAC can be evaluated as a sulfur-containing amino-acid derivative for nutrition ingredient development, botanical active research and biochemical research. The page does not make therapeutic claims.
The referenced COA lists 1 kg/bag packaging. Store sealed, cool, dry and away from light; confirm current shipping conditions for each order.
