TruMarine Collagen + MAGNESIUM

This product was a labour of love for our fonder, Tami, who had a large part in creating and developing this innovative product, which took several years before we launched it to the public. 

withinUs™ TruMarine® Collagen + Magnesium is a CLEAN, non-GMO, carefully-sourced, superior, premium-grade supplement with 2 sources of magnesium, L-theanine, and TruMarine® Collagen. It contains zero sugar and no preservatives. 

With a subtle flavour of organic lemon, it can be added into hot water or herbal tea.

Magnesium is a well-recognized product in the health and wellness industry. As with all products, there are varying qualities when it comes to magnesium which ultimately affects the benefits these products offer and the overall absorption rate.  

We have compiled some “need to know” facts about magnesium and information about why TruMarine® Collagen + Magnesium is a superior magnesium supplement and how you will benefit from adding it to your nightly routine.

Why do I need magnesium?

Magnesium is required to regulate and stimulate over 300 biochemical reaction systems within the body including nerve impulses and muscle contractions, this includes functions as simple as blinking, to as complicated as your heart beating to pump blood throughout your body. 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, muscle cramps, lack of motivation and difficulty sleeping.

When should I take magnesium?

    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. 

    How do I choose which form of magnesium is the best form to take?

      There are various forms of magnesium, which we’ve listed below from highest to lowest quality:

      HIGH (withinUs™ TruMarine® Collagen + Magnesium)

      Magnesium Citrate:

      This form of magnesium is bonded to citric acid, which increases the rate of absorption. It is more bioavailable (1), meaning your body will absorb and utilize it most efficiently. 

      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 Chloride/Magnesium Sulphate:

      More commonly found in Epsom salts, gels, oils, lotions, and sprays. When taken orally, these forms will have a very strong laxative effect. These are less expensive sources of magnesium.

      Magnesium Oxide:

      This is the most inexpensive source of magnesium, however, the absorption rate is only 4-10%. 

      withinUs™ has 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.  

      Note - Powder vs Pill:

      In order for supplements to be best utilized by the body, they should be in a form that it can actually use. Therefore, digestion, absorption and assimilation of a supplement are key to how well it works. Capsules, pills and tablets must dissolve before the active ingredients they contain become available to the body. For many reasons, including age, celiac disease, IBS, use of medication, pH, and functional changes (such as surgery), the digestive system might not be able to completely break down pills into a usable form. Conversely, powders don't require this step and therefore result in quicker assimilation into the body.

      What sets withinUs™ TruMarine® Collagen + Magnesium apart from the rest?

        • A unique combination of the two most superior forms of magnesium (citrate and bisglycinate) 
        • The addition of the restorative amino acid L-Theanine 
        • Sedative-free (we do NOT add melatonin to our product due to unwanted side-effects such as morning drowsiness, vivid dreams, small changes in blood pressure, nausea, headaches and dizziness)

        • Contains the highest grade of collagen peptides available as it is a premium select grade source (exclusively from scales of wild-caught, sustainable fish) withinUs™ TruMarine® Collagen

        How much magnesium do I need?

          The RDA (Recommended Dietary Allowance) for magnesium is 310–420mg for adults depending on age and gender. Our withinUs™ TruMarine® Collagen + Magnesium contains 250mg per serving to supplement the magnesium you consume through food. 

          Does magnesium have a laxative effect?

            When consumed in large quantities, magnesium can be used as a way to keep you regular. Our customers, however, should not experience this with our withinUs™ TruMarine® Collagen + Magnesium blend.


            TruFact: withinUs™ TruMarine® Collagen + Magnesium helps promote muscle relaxation, making night time an optimal time to take this supplement. Research also shows that using an oral magnesium supplement powder can improve the quality of sleep. With the addition of Lysine in TruMarine® Collagen, withinUs™ TruMarine® Collagen + Magnesium promotes deep, restorative sleep and relaxation, making it the perfect night-time concoction.
