How to Choose
Aged Garlic Extract vs Standard Garlic vs Black Garlic
Aged garlic extract (Kyolic-type) undergoes a 20-month cold aging process that produces high SAC levels with no odor. Fermented black garlic undergoes a heat-accelerated Maillard reaction (2-6 weeks) producing SAC plus melanoidins. Standard garlic extracts contain allicin-derived compounds but less SAC. For cardiovascular benefits, aged or fermented garlic is strongly preferred over standard garlic extracts.
Look for SAC Standardization
S-allyl cysteine (SAC) is the primary bioactive compound and has 98% oral bioavailability — far superior to allicin from raw garlic. The best products standardize their SAC content per serving. If a product does not mention SAC on the label, it may not have undergone sufficient aging to produce therapeutic levels.
Clinical Dosing for Cardiovascular Benefits
Blood pressure reduction trials typically use 600-1200mg/day of aged garlic extract. Cholesterol trials have used up to 2400mg/day. The immune function trial by Nantz et al. used 2560mg/day. For general cardiovascular support, 600-1200mg daily is a good starting range. Higher doses show greater effects but also increase cost.
