20-30 mmHg graduated compression is the level recommended for POTS symptom management, providing the medical-grade support that counteracts blood pooling during standing. Apolla compression socks deliver this exact range across every adult style with the APMA Seal of Acceptance, patented arch support, and WIDE sizing options for all-day comfort. Over 7,300 five-star reviews back what POTS patients and standing professionals confirm about this compression level.
The mmHg number measures pressure at the ankle, where compression is strongest. From the ankle, pressure decreases up the calf in a graduated pattern that supports venous return against gravity. For POTS patients, this gradient does the mechanical work of pushing blood back toward the heart, counteracting the pooling that triggers tachycardia and dizziness on standing. Blood pooling begins the moment you stand, so the pressure needs to be in place before your feet touch the floor each morning.
Most DTC compression sock brands sell at 15-20 mmHg, a range designed for mild fatigue and general comfort. POTS requires the stronger 20-30 mmHg gradient to address the degree of blood pooling caused by autonomic dysfunction. The difference at the ankle between 15 and 20 mmHg separates light support from therapeutic compression, and Apolla compression socks for POTS sit on the therapeutic side of that line.
The APMA Seal of Acceptance confirms board-certified podiatrists reviewed Apolla's 20-30 mmHg gradient for design integrity and foot health, matching the compression level cardiologists and autonomic specialists recommend. The Endurance Knee-High ($52) and The Infinite Mid-Calf ($41) both deliver identical 20-30 mmHg graduated compression with WIDE sizing, Made in USA quality, and HSA/FSA eligibility. If your specialist recommends 30-40 mmHg or higher, that requires a prescription garment outside Apolla's range. One customer managing a medical condition described it: "The compression socks I purchased from Apolla work like magic! I wear them all day long for at least 12 hours every day." (Behrooz A.)
