Known Nutrition Ashwagandha vs Life Extension Ashwagandha: What Does the Data Say?
The most striking difference isn't the price gap — it's what you're actually swallowing. Known Nutrition's gummies list glucose syrup and sucrose ahead of the ashwagandha itself, which matters if you're taking them every day. Life Extension's capsules use a standardised extract, delivering consistent withanolide content per dose — the active compounds behind ashwagandha's stress and cortisol effects. That's why Life Extension scores higher on ingredient quality (81 vs 63), even though Known Nutrition edges ahead on effectiveness (80 vs 74).
At £9.74, the Known Nutrition gummies suit anyone who struggles with capsules, or parents looking for something a teenager will actually take. The apple flavour genuinely helps with daily consistency, and the value score (76 vs 62) reflects that gap clearly. At £24.00, Life Extension is better suited to adults who want a precisely specified extract — particularly if you're monitoring sleep quality or stress response over time. One point in the gummies' favour: they're third-party tested and hold ISO, GMP, and BRC certification. Life Extension has decades of GMP manufacturing behind it but no independent third-party testing listed here. If you ever need to open a Life Extension capsule, the contents are reportedly quite bitter.
