Hard Capsules

Rachel, 37, struggled with 3 AM wake‑ups and racing thoughts. Her yoga teacher recommended ashwagandha—an Ayurvedic adaptogen used for thousands of years.

Active compounds: withanolides, which modulate the HPA axis, influence cortisol, and support GABAergic relaxation.

Clinical evidence: A 2021 review of 7 studies (491 adults) showed ashwagandha significantly reduced stress, anxiety, insomnia, fatigue, and serum cortisol versus placebo. A 2025 trial found 125mg daily improved perceived stress, anxiety, and sleep quality. In 150 adults with sleep issues, sleep quality improved by 72% vs. 29% for placebo.

DUOZI Ashwagandha Capsules: 300mg root powder + 5mg BioPerine® for absorption, 60 capsules/bottle, 1 daily. Rachel noticed fewer racing thoughts after six weeks.

Sophia, 32, felt insecure about her curves and discovered maca—a Peruvian adaptogenic herb rich in amino acids, minerals, and macamides. Maca supports energy, stamina, mood, and overall balance, indirectly aiding body shaping through improved training performance.

DUOZI Ultimate Maca Plus delivers 7,500mg proprietary complex per serving (Maca Root, Black Maca, Fenugreek, Tribulus, Aguaje, Tongkat Ali), 15:1 high‑concentration extract, 120 vegetable capsules (40‑day supply). Best results after 2–3 months with regular exercise and balanced diet.

Mike, 47, felt constantly "out of battery." His doctor mentioned CoQ10—a fat‑soluble substance that acts as a key cofactor in mitochondrial ATP production and a powerful antioxidant.

CoQ10 peaks at age 20 and declines steadily—by 80, heart levels are half. Statins, antidepressants, and oral contraceptives may also deplete CoQ10.

Clinical evidence: Q‑SYMBIO trial (420 heart failure patients) showed 100mg CoQ10 three times daily reduced major cardiovascular events. Cochrane review confirmed reduced mortality and hospitalization rates.

DUOZI CoQ10 100mg capsules (1 daily with fat‑containing meals, 60/bottle, GMP‑certified). After 6 weeks, Mike noticed less afternoon fatigue and better weekend endurance.
