Hard Capsules

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.

Claire, 33, struggled with irregular cycles and PCOS. Her doctor recommended inositol—a sugar alcohol that acts as a second messenger in insulin signaling. About 70‑80% of obese PCOS patients have insulin resistance, affecting ovarian function.

The 40:1 golden ratio: Healthy ovaries maintain a Myo‑inositol to D‑chiro‑inositol ratio of 40:1. MI supports follicle development; DCI regulates testosterone metabolism.

Clinical data: 2024 study showed inositol improved PCOS metabolic and reproductive outcomes (live birth RR 2.29, ovulation RR 2.75).

DUOZI Inositol Complex Capsules deliver 2000mg inositol (40:1 ratio) plus active folate and vitamin D3. Claire saw her cycle shorten from 60+ days to ~40 days after 2 months.
