Frequently Asked Questions
What is SF Zero?
SF Zero is a nightly cacao drink designed to help your body sleep better, without using melatonin. You stir one scoop into warm milk or water about twenty minutes before bed. Inside the bag are ten ingredients chosen for what actually helps the body wind down: four active ones at clinical doses: magnesium glycinate, L-theanine, apigenin, and ashwagandha KSM-66 and six supporting ones, including real cacao, that turn the formula into something you'd actually want to drink. Every milligram is printed on the bag and every batch is third-party tested.
What makes SF Zero different from other sleep products?
Most sleep supplements lean on melatonin, the hormone your body already produces in tiny amounts. The doses on the shelf are often ten to thirty times what your brain actually makes, and the research on long-term use is increasingly concerning. SF Zero is built on the opposite idea: your body already knows how to sleep, it just needs the right building blocks. We chose four active ingredients backed by replicated human studies, dosed them at the levels real research uses, and put every milligram on the label. No melatonin, no proprietary blends, no fillers we couldn't justify.
Is it safe to drink every night?
Yes. All ten ingredients are at doses supported by peer-reviewed research for nightly use, and none of them are habit-forming. SF Zero contains no hormones, no sedatives, and nothing your body builds tolerance to. Every batch is third-party tested for purity and dose accuracy. If you're pregnant, nursing, or taking medication, we'd recommend checking with your doctor first, the same advice that applies to any supplement.
How long until I notice a difference?
Most people feel something the first night, falling asleep faster, a calmer mind, less of the racing-thought loop. The deeper effects tend to land in the second week as the magnesium and ashwagandha build up in your system. Sleep is a longer-term habit, not a single dose, so we recommend giving it the full thirty nights before deciding whether it works for you. If by then you don't notice a meaningful difference, the bag is on us.
What if it doesn't work for me?
Then it's free. Every order comes with a 30-night sleep guarantee. Full refund, and you keep the bag. If you're on a subscription, you can cancel it in one click from your account dashboard. No phone calls, no retention emails, no friction. Sleep is personal, and we'd rather you find what works for you than feel locked into something that doesn't.
