The brand
A small brand with a tight range built entirely around evenings and winding down. Strong on taste and texture, narrower on range.
Sustainability
Refillable ceramic caddy with paper refills.What is in it
Every active ingredient amount is printed on the label.
Magnesium bound to the amino acid glycine. Generally better tolerated by the digestive system than magnesium oxide, and usually more expensive. Typical serving across the market: 100mg – 375mg elemental. Published human research: moderate.
An amino acid found in tea leaves. Frequently combined with caffeine in focus formulas because the pairing is better studied than either alone for attention tasks. Typical serving across the market: 100mg – 200mg. Published human research: moderate.
Other ingredients
Glycine 3,000mg, Tart cherry powder, Natural vanilla, Steviol glycosides.

How the cost works out
Cost per serving is the fairest way to compare, because pack sizes vary enormously within the same category. It still does not account for how much active ingredient is in each serving — check that too.
