"Resemblance to studied formulations" describes how closely this product's extract, form and dose match preparations used in published research - it is not a claim that the product itself has been clinically tested, and it does not mean the product "works" for any individual.

Ingredients & suitability

Manufacturer states 6000mg of dried ashwagandha (not stated as an extract ratio) per one-a-day capsule serving. 60 capsules. Manufacturer states identity testing via HPTLC to confirm the correct herb species and plant part, describing this as exceeding standard EFSA requirements; no specific report was linked on the listing. Note: this is labelled as dried ashwagandha (whole herb), not a concentrated extract – there is no extract ratio or raw-equivalent conversion involved, so the 6000mg figure is the actual material mass. Correction: the ingredients panel (not shown in the main marketing bullets) discloses this as a 10:1 root extract – 6000mg is a raw-herb equivalent, and 600mg is the actual extract mass (6000 ÷ 10). A single capsule could not physically contain 6000mg of material, which is what prompted this re-check.

Manufacturer statement
Batch-specific COA (batch 57080) from Together Health Ltd, signed by the manufacturer's own QA (Bob Clough), states "Analysis performed by a 3rd party lab, accredited by UKAS" but does not name the lab. Read directly: no identifiable independent lab, so recorded as manufacturer-provided COA rather than verified independent lab testing.
