Questions people ask before they try Biopeptide
What is Kincadence?
Kincadence is a US supplement brand from Longevity Hub LLC in Wilmington, Delaware. We build focused daily formulas around clinically studied, named ingredients at the doses used in the research, starting with Biopeptide, a melatonin-free capsule for sleep and everyday stress.
What is Biopeptide and how do I take it?
Biopeptide is a once-nightly vegetable capsule with 150 mg of α-casozepine, a bioactive peptide from milk protein. It is melatonin-free, non-hormonal and non-habit-forming. Take one capsule 30 to 60 minutes before bed.
What is α-casozepine?
α-casozepine is a peptide released from αs1-casein, a milk protein, by enzymatic hydrolysis. It has been studied in placebo-controlled human trials for everyday stress and sleep quality. It works with GABA, the brain's own calming signal, instead of adding a hormone or a sedative.
Why do I keep waking up at 3 AM?
A nervous system that stays switched on at night is one common reason people wake in the early hours and cannot drop back off. Biopeptide is built for that pattern: it supports your brain's calming signal so the stress response can settle, without sedating you.
How is Biopeptide different from melatonin?
Melatonin is a hormone that signals the time of day to your body clock. α-casozepine is not a hormone and does not act on your body clock; it works with your brain's own calming pathway. Biopeptide contains no melatonin, so there is no next-day fog.
How is it different from magnesium, ashwagandha or valerian?
Magnesium is a mineral your body uses for hundreds of processes, and ashwagandha and valerian are herbs with broad effects. α-casozepine is a single, specific milk peptide with its own human studies on stress and sleep, and it works with the GABA calming signal directly. Biopeptide contains only that one active, so you know exactly what you are taking and at what dose.
Will it make me groggy? Is it habit-forming?
No on both counts. α-casozepine is not a sedative and is non-habit-forming. The effect is calm rather than knocked out, and there is no morning grogginess.
How long until I notice a difference?
Calm support is often felt within the first week, while sleep quality tends to build over two to four weeks of nightly use. Individual experiences vary, so give it a full month for the best read. Every order is covered by a 90-day money-back guarantee.
Who is Biopeptide for?
Adults whose stress follows them to bed: the 3 AM waker, the tired-but-wired, people on shift or travel schedules, and anyone in midlife who wants to sleep and handle stress the way they used to. It is for men and women alike. It is not intended for children.
Does it contain dairy? Is it vegan or gluten-free?
Biopeptide contains milk. α-casozepine comes from milk protein, so it is not vegan and not suitable for anyone with a milk-protein allergy. It is gluten-free and contains no caffeine, artificial fillers or synthetic additives.
Can I take it with medication, or while pregnant or nursing?
α-casozepine is a food-derived milk peptide that has been well tolerated in clinical studies. Even so, if you are pregnant, nursing or taking medication, ask your doctor before use.
Where is it made and how is it tested?
Biopeptide is made in a cGMP facility and third-party lab tested. Every ingredient and its dose is printed on the label. There are no proprietary blends.
Where do you ship, and what is the guarantee?
We ship to the United States, Canada and Australia with tracking. Standard shipping is free on orders over $60. Every order comes with a 90-day money-back guarantee: if you do not feel the difference, we refund you.
