Comparisons / NOW Foods Ashwagandha 450mg vs Rasayanam Ashwagandha KSM-66 500mg
# Verdict: Rasayanam Edges Ahead with Premium Extract **Winner: Rasayanam Ashwagandha KSM-66** (7.3/10 vs 6.9/10) Rasayanam takes the lead primarily due to its **KSM-66 extract** — a clinically-studied, full-spectrum root extract that's considered the gold standard for ashwagandha. This explains its superior Formula score (7.5 vs 6.7) and Dosing score (7.2 vs 6.7). NOW Foods provides 450mg of ashwagandha with 11mg withanolides (2.4% concentration), while Rasayanam delivers 500mg of pure KSM-66 extract standardized to 5% withanolides (25mg) — **more than double the active compounds**. **Price difference is minimal**: Rasayanam costs ₹13.32 per serving versus NOW's ₹14.43, making it **₹1.11 cheaper daily** while offering superior quality. That's ₹33 monthly savings with a better product. Both brands score perfect 10.0 on transparency, but Rasayanam's Value score (4.6 vs 4.3) reflects better cost-effectiveness for the extract quality provided. **Recommendation**: Choose Rasayanam unless you specifically need a lower-potency option. The KSM-66 certification, higher withanolide content, and lower price make it the clear choice for most Indian consumers seeking stress relief and adaptogenic benefits.
