🔬 How to Choose the Right Ashwagandha Supplement
Selecting the right product depends on your goals, tolerance, and lifestyle.
Here’s what to consider before buying:
1. Look for Standardized Extracts
Choose KSM-66 or Sensoril — both clinically validated forms with consistent withanolide concentration.
2. Check Dosage
An effective daily dose is 300–600 mg of root extract (not leaf). Split doses can enhance absorption and reduce mild digestive discomfort.
3. Prioritize Clean Ingredients
Avoid fillers, synthetic binders, or “proprietary blends” with undisclosed ratios. The best products list exact extract percentages.
4. Know Your Goal
- For sleep & stress: Go for KSM-66 or Sensoril.
- For energy & vitality: Try blends with Black Pepper or Panax Ginseng.
- For purity & daily balance: Choose organic, root-only options.

🩵 PrimeAura Insight: Adaptogens like Ashwagandha work best when taken consistently for 4–8 weeks. Pair with a balanced diet and regular sleep schedule for maximum results.

Brands like Himalaya, NOW Foods, Organic India, and Goli meet most of these criteria globally.
