    We recommend taking three capsules with a well-balanced meal and water before and after the party.

    No. So, please party responsibly and never get behind the wheel, if you've indulged!

    Yes. We use the most active and absorbable form of our ingredients, rather than opting for cheaper forms. All of our ingredients are tested at multiple stages in the manufacturing process, so what's on our label is exactly what's in our products and they meet rigorous health and safety standards. Regardless of that, we ask that our customers always pay attention to keep track of their dosages and never consume more than what is recommended.

  • Is Flyby Recovery manufactured in the USA?

    Yes! We manufacture Flyby Recovery in California.

  • Is Flyby Recovery FDA approved?

    Because Flyby is a nutritional supplement, it does not require FDA approval (and cannot be approved by the FDA). Despite this, we manufacture all of our products in facilities that are FDA approved and cGMP certified. What does that mean? Our facilities are held to strict protocols and standards to assure proper design, monitoring, and control of the manufacturing process. This assures that the identity, strength, quality and purity of our products are not compromised and are adequately controlled throughout the entire manufacturing process.

  • Can I take Flyby Recovery if I'm pregnant?

    We do not recommend drinking while you are pregnant. We recommend that you talk to your physician before adding any supplements or medications to your diet.

  • Can I take Flyby Recovery with other medications?

    Because every individual response is different, we recommend speaking with a physician before adding any supplements to your diet, if you're currently taking medications.

  • Does Flyby Recovery contain electrolytes?

    Yes! Flyby Recovery contains an optimized blend of magnesium, sodium and potassium to keep you hydrated in the morning. But while hydration is important, it’s only not the only reason why you wake up feeling crappy. There are other contributing factors such acetaldehyde buildup, GABA rebound which are reduced by our formula.

  • How much Dihydromyricetin (DHM) is in each serving of Flyby Recovery?

    That's top secret. Unfortunately, due to the proprietary nature of our formula, we cannot tell you an exact amount, but trust us when we say there is over 300mg of DHM per serving in Flyby Recovery.

  • Does Flyby Recovery contain caffeine in it?

    No, there is zero caffeine in Flyby Recovery so you don't have to worry about staying awake all night.

  • Can you remove the capsule contents and mix it with water?

    We would not recommend removing the contents from the capsule and taking it with water as the taste may not be the most pleasant and DHM will not dissolve properly in water. We'd suggest mixing the powder into a smoothie or juice in order to mask the taste.

Magnesium Product Info

  • Why is Flyby Magnesium a better sleep support option than melatonin?

    Magnesium will not cause drowsiness or make a person feel groggy which is an effect commonly attributed to melatonin. Magnesium can help muscles relax, which in turn can help calm and bring on a better state of mind for sounder sleep.

  • I’ve tried other types of magnesium, but they haven’t worked. How is this formula different?

    Flyby Magnesium is so much more than just magnesium! Magnesium in and of itself is not a sleep aid in the sense that it does not have any narcotic properties. Its purpose in our formula is to serve as a mild muscle relaxant to help ease into a more relaxed state in order to facilitate natural sleep and a clearer mind. We use forms magnesium citrate & oxide because they great choices for pre-bedtime supplementation to support restful sleep and are also neurotransmitters that promotes relaxation and stress reduction in the body.

  • How long does it take Flyby Magnesium to improve sleep? Do you recommend taking it every night?

    It will usually take 1-2 weeks for your body to adjust to our formula. That said, it is not uncommon for people to experience benefit on the first night they take it. We recommend taking Flyby Magnesium every night to reap the full benefits.

  • When should I take Flyby Magnesium?

    You can take Flyby Magnesium at any point in the day when you feel stressed or anxious, or when you would like to feel more relaxed or calm. For sleep, we strongly suggest taking Flyby Magnesium 1-2 hours before bed. While we recommend taking a standard dose of 1 capsules per night, you can take up to 4 capsules depending on your sleep needs.
