Started using mine this week, I noticed a difference in my sleep by the second night! Restless legs settled down and slept more sound! Love your products!


I've used it for three nights now, and absolutely love it!! Prior to this I religiously took magnesium every night for years - but this has been an obvious game changer! Thanks withinus.


In love with this!!! I have been struggling for so long and nothing seemed to help me with sleep. I am so happy I tried this. Just ordered my second one because I’m afraid to run out.

What is withinUs TruMarine™ Collagen + Magnesium?

withinUs TruMarine™ Collagen + Magnesium will complete your night-time routine. The unique combination of the amino acids L-theanine and Glycine work together to promote relaxation, helping you get a more restful sleep while stimulating collagen production within the body. The subtle hint of organic lemon makes it enjoyable on its own in warm water or in non-caffeinated tea. Sweet dreams.


Magnesium is required to regulate and stimulate over 300 biochemical reaction systems within the body including: nerve impulses and muscle contractions. This includes simple functions such as blinking, or more complicated such as your heart beating. These nerve impulses and muscle contractions are essential for our survival.

It is difficult to get enough magnesium (in today’s world) from food alone making supplementation an ideal solution. Symptoms of magnesium deficiency include:

  • Fatigue
  • Depleted energy
  • Lack of motivation and difficulty sleeping
  • Painful muscle cramps, spasms or eye twitches
  • Stress or suffering from anxiety, hyperactivity or irritability

We have chosen to include a combination of magnesium citrate and magnesium bisglycinate in order to offer a product with maximum absorption that is easy on the digestive system

Magnesium Bisglycinate

In this form, magnesium is bonded to the amino acid glycine. Glycine itself is a soothing neurotransmitter that enhances magnesium’s natural relaxation properties. This form is best/ideal for mental calm and relaxation.

Magnesium Citrate

This form of magnesium is bonded to citric acid, which increases the rate of absorption. It is more bioavailable, meaning your body will absorb and utilize it most efficiently.


L-theanine, is a calm-enhancing amino acid. It promotes relaxation and reduces nervous tension by stimulating alpha wave activity in the brain.

withinUs TruMarine™ Collagen:

withinUs TruMarine™ Collagen is 100% Ultra-Pure, exclusively and sustainably sourced from the deep clean waters of the South Pacific Ocean. Our Premium-Select grade collagen is clinically proven to have superior bioavailability when compared to other collagen sources, including fish skin collagen. Collagen is the most abundant structural protein in the body. As we age, our body slows the production of collagen, causing us to lose approximately 1% of our collagen per year. Collagen plays an extremely important role in the cohesion, elasticity and regeneration of skin, bones, tendons, ligaments and skeletal muscles.

withinUs TruMarine™ Collagen + Magnesium is an optimal supplement to take before bed. The body uses magnesium efficiently at night as it is involved in many of the repair processes conducted during sleep. Magnesium also offers a calming effect on your muscles and nervous system which can help relax the body, assisting in a good night’s sleep.
