Magnesium is involved in over 300 enzymatic reactions in the body. It is needed for blood pressure regulation, bone strength, energy production, muscle and nerve function and much more.

Our modern day diets tend to be magnesium-poor, due to lower mineral content in the soil and food processing and storing methods. A good quality supplemental source of magnesium can help support the many processes this essential mineral is involved in.

A superior source of magnesium

Cabot Health Ultra Potent Magnesium Powder combines 4 different forms of magnesium, to optimise the body's absorption and utilisation. It also does not contain magnesium oxide, which is poorly absorbed and can have laxative properties.

Only one teaspoon delivers the daily therapeutic dose: 400mg of elemental magnesium.


  • In powder form, to help further with optimal absorption.
  • Formulated by medical doctors and naturopaths.
  • Free from artificial colours or sweeteners, dairy, gluten, sugar and yeast.
  • Free from calcium, a mineral that has the opposite effect of magnesium.
  • Contains added taurine which helps calm the nervous system.
  • Contains zinc, which helps for the production of mood-stabilising neurotransmitters.

What you can expect from taking Ultra Potent Magnesium Powder

  • Reduced anxiety and stress: magnesium has a calming and relaxing effect on the nervous system. Stress depletes the body’s magnesium reserves, which makes us more prone to stress, creating a vicious cycle.
  • Headache and/or migraine management: studies have shown that headaches or migraines can be helped by magnesium supplementation, as it reduces blood vessel constriction and spasms. Magnesium could be used to try and reduce the severity and frequency of headaches and migraines (in conjunction with selenium, which may help decrease inflammation present with headaches).
  • Fewer muscle cramps: muscle spasms and cramps are often linked to an electrolyte imbalance. Magnesium most commonly deficient out of all of these, and associated with muscular tightness, cramps and spasms. A magnesium supplement usually helps relieve cramps.
  • Improved sleep: magnesium is a great supplement to take in the evenings, as it helps to calm the nervous system, promotes relaxation and helps reduce stress.
  • Stabilised blood sugar: magnesium assists with glucose transport and insulin release, important roles in glucose metabolism. A magnesium supplement could be beneficial for those with type 2 diabetes or insulin resistance.
  • Improved mood: insufficient levels of magnesium can impact levels of serotonin. A magnesium supplement could help to improve mood.
  • Healthier bowel motions: magnesium has smooth muscle-relaxant properties and can be beneficial for those suffering from constipation. Magnesium could help to relax bowels and enable easier passing.
  • Normalising blood pressure: magnesium can have a relaxing effect on the walls of the arteries, which allows a freer blood flow. Because magnesium can also help to reduce stress, this can have a beneficial effect in lowering the risk for high blood pressure.
  • Improved energy levels: magnesium plays a very important role in energy production. Depleted levels of magnesium could be related to low energy.
  • Bone strength: magnesium deficiency has been linked with decreased bone density, and as a result an increased risk of fracture. A large amount of magnesium is stored in the bones, and could help with their health.
