1 Source Supplements in the United Kingdom has comprehensive product solutions for a lot of situations, areas of health, and performance purposes, and it even digs into some of the rarely touched spaces. Included in the brand’s strong list of categories covered, it has the sleep aid Knockout1, which features a solid formula considering the rules and regulations on a lot of nighttime ingredients in the UK and Europe, with the likes of lemon balm, 5-HTP, theanine, and KSM-66 Ashwagandha.
Here in April, 1 Source Supplements has decided to revamp its nighttime solution, Knockout1, filling it with more ingredients for even greater relaxation, sleep, and rest support, as well as knockout ability. The sequel carries over all of the original components with some slight changes in dosages and forms. The brand has drastically dialed up the magnesium from 400mg to a gram, packed in 25% more lemon balm, increased theanine by 20%, moved to Shoden ashwagandha, and added apigenin.
Knockout1 still obviously remains a focused, deep sleep supplement, although for the 2026 edition, the brand has tried to take things up a notch and deliver even greater, deeper sleep to maximize recovery, growth, and performance. 1 Source Supplements has elevated things so much that the formula requires a bigger six-capsule serving, up from four, and fans can experience it for themselves by purchasing Knockout1 directly through the brand’s website at £35.99 (48.70 USD) for a 30-serving bottle.
