Protocol, KSM-66 Ashwagandha®, Stress and Sleep Support 600 mg by Protocol for Life Balance

KSM-66 ashwagandha fits adults under sustained daily strain who want to feel less wound up and sleep more soundly, and who prefer a root-only extract in a one-capsule serving. If you track labs, morning Cortisol is the marker most often followed. Talk to your clinician first if your TSH, Free T4 or Free T3 is out of range or you take thyroid medicine, because ashwagandha can push thyroid hormone upward. The label states that it is for adults only.

Each capsule contains 600 mg of organic KSM-66, a branded extract of the root of Withania somnifera. Ashwagandha is classed as an adaptogen. Its withanolides appear to temper the HPA axis, the stress loop that links the brain to the adrenal glands, and to act on GABA signaling, the brain's main calming system. Trials of root extracts report lower perceived stress, modestly lower cortisol and somewhat better sleep, though most are small and run only 8–12 weeks.

The label directs 1 capsule daily, or as directed by your healthcare practitioner. One capsule provides 600 mg of the extract. Taking it with food may limit stomach upset. Evening suits people whose aim is sleep or who feel drowsy after a dose; morning suits those who find it mildly energizing. It works through steady daily use, not as a take-as-needed calming aid.

The label says it is not recommended for pregnant or nursing women, and to consult a physician if you take medication, especially thyroid hormones, or have a medical condition, especially a thyroid, liver or gastrointestinal condition, including ulcers. Ashwagandha can also add to the effect of sedatives, sleep medicines and alcohol, and may stimulate immune activity, so ask your specialist if you have an autoimmune condition or take immunosuppressants. Rare liver injury has been reported: stop and have ALT and AST checked if you notice dark urine or yellowing eyes.

Some people notice calmer edges or easier sleep within 1–2 weeks; fuller changes in perceived stress and sleep quality take 4–8 weeks. The label warns of digestive upset in sensitive people and says to stop if you have any gastrointestinal discomfort or a rash or itching. Long-term safety data are limited, so reassess after about three months. Magnesium glycinate and L-theanine are gentler options if you want calm without an herb that acts on hormones.
