Ashwagandha KSM-66 test results

Batch results are being updated.

A supplement is easy to claim and hard to check. So we publish the figures rather than describing them: the result for the batch in your hand, the limit it was measured against, and the name of whoever set that limit.

Every batch is tested before it is released. Nothing ships on the strength of a previous result.

Directions

How much: 2 capsules a day, which is 600 mg of KSM-66, with a glass of water. One pack holds 60 capsules and lasts 30 days.

When: preferably with a meal, at about the same time each day, as part of your daily routine.

How long: take it every day for a full pack before you judge it. That is what the 30-day money-back guarantee is for: if it is not for you, you get your money back.

Storage: keep the pack closed in a cool, dry and dark place at room temperature (15 to 25 °C).

Good to know: do not take more than 2 capsules a day. If you are pregnant, breastfeeding or take medication (including thyroid, blood sugar, blood pressure or sedative medication), check with a healthcare professional first. Stop and seek advice if you experience any adverse reaction. Keep out of reach of young children.

Can I still drink coffee?

Yes. Ashwagandha KSM-66 has no caffeine. You can take it with breakfast, next to your first coffee of the day.

The figure is on the certificate, not just in the copy

Publishing a result you have not read is the same as not testing at all. Every number above comes off the laboratory's own report, and the report is on the page beside it.
