Overview
Dynamic Calm pairs 600mg of KSM-66 ashwagandha with L-theanine, rhodiola rosea, holy basil and magnesium glycinate in a single vegetarian capsule. Stonehenge Health markets the 60-capsule bottle for daily stress and mood support.
KSM-66 is a specific standardized ashwagandha extract, so naming it on the label is a more concrete claim than a generic ashwagandha listing. Rounding out the formula with L-theanine and magnesium glycinate targets calm rather than the stimulant-style energy some stress supplements lean on.
- 600mg KSM-66 ashwagandha
- L-theanine, rhodiola rosea, holy basil added
- Magnesium glycinate included
- 60 non-GMO vegetarian capsules
Who it's for
Aimed at adults who want a named, standardized ashwagandha extract rather than an unspecified one, paired with a few complementary calming ingredients. Not built for anyone needing a vegan capsule, since this one is vegetarian.
Strengths and trade-offs
Drawn from this product's published specifications.
- Names a specific standardized extract, KSM-66
- Combines ashwagandha with L-theanine and magnesium glycinate
- Non-GMO, vegetarian capsules
- Does not break down individual ingredient amounts within the 600mg total
- Vegetarian capsule, not vegan
Performance notes
600mg of KSM-66 sits within the dose range commonly used in ashwagandha research, though the listing does not break out how much of the 600mg is the extract itself versus the added ingredients. Magnesium glycinate is generally chosen for gentler absorption than other magnesium forms.
