Ashwagandha (Withania somnifera) is one of the best-studied adaptogens — herbs that help the body adapt to stress. With piperine for absorption, it is most often chosen for:

  • Stress & cortisol — helps maintain normal cortisol levels and supports resilience under stress.
  • Sleep quality — supports falling asleep faster and improving restorative sleep.
  • Energy & vitality — contributes to physical and mental stamina throughout the day.
  • Mood & cognition — supports normal psychological balance, memory, and focus.

Take 1 capsule once daily, providing 1,000 mg Ashwagandha extract (50 mg withanolides) plus piperine for enhanced absorption. Swallow with water, ideally in the evening to support relaxation and sleep, though it can also be taken in the morning for daytime stress resilience.

Consistent daily use for at least 6–8 weeks is recommended in clinical studies for stress, sleep, and vitality benefits.

Ingredients: Ashwagandha root extract (Withania somnifera, standardised to 5% withanolides, providing 50 mg withanolides per capsule), black pepper extract (Piper nigrum, providing piperine), vegetarian capsule (HPMC).

Free from: fillers, binders, stabilisers, GMOs, and common allergens.

Clinical research has explored Ashwagandha’s adaptogenic and restorative effects:

  • Stress & cortisol: 300–600 mg/day of standardised root extract reduced perceived stress and lowered cortisol by up to 27% in RCTs (Chandrasekhar et al., 2012, Indian J Psychol Med).
  • Sleep: 600 mg/day improved sleep quality and reduced sleep latency (Langade et al., 2019, Cureus).
  • Strength & recovery: 600 mg/day increased muscle strength, recovery, and testosterone in young men (Wankhede et al., 2015, J Int Soc Sports Nutr).
  • Cognition & mood: 500–1,000 mg/day has shown improvements in memory, attention, and anxiety scores (Choudhary et al., 2017, J Diet Suppl).

Our formula delivers 1,000 mg extract daily, providing 50 mg withanolides, plus piperine to optimise absorption — placing it firmly within and above the doses used in successful clinical studies.

Safety: Ashwagandha is well tolerated in human trials up to 1,250 mg/day extract for several months. Mild digestive upset or drowsiness may occur in sensitive individuals.

Frequently Asked Questions

Most high-street brands underdose their products, the active ingredients are far below the levels used in real studies. Online it’s even riskier: many cheap supplements are shipped directly from overseas suppliers (often China), with little transparency or quality control, so you can’t be sure what’s actually inside.

SuperDosed™ takes the opposite approach. Every formula is made in the UK, fully tested, and built at the same strength shown effective in human studies. Our products are vegan-friendly, free from unnecessary additives, and designed by Oxford-educated doctors with deep expertise in nutrition and clinical research.

We use clinical-dose formulas — each product matches the levels shown effective in human studies, not watered-down amounts.
