Smooth Mag Complex Powder
Magnesium is probably the most popular of all of the minerals at the present time, especially as consumers are becoming increasingly aware of its research-proven benefits in preventing or treating stress symptoms, tension, insomnia, muscle spasms, fatigue, premenstrual syndrome and high blood pressure and other cardiovascular disorders. Magnesium is also increasingly popular with athletes as it may assist in muscle recovery and even energy during training. Smooth Mag is an innovative and highly bioavailable blend of high-absorption magnesium which is synergistically enhanced with pyridoxal 5-phosphate (which facilitates magnesium function), inositol, FOS, soluble stabilized rice bran, green oat seed (Avena sativa) and Montmorency cherry. This unique formulation is in an easy-to-mix, unflavoured (but mild tasting) powder form, which can be stirred into water, juice, plant-based milk alternative or milk.

Fettle is a health store, reimagined.
Built in Holmfirth. Inspired by the wild.
We stock a wide range of curated products - carefully chosen foods, proven supplements, and low-impact home goods—with one aim: to help people feel well, live fully, and tread lightly.
We're guided by four principles:
Roam – move with purpose
Replenish – eat well, choose consciously
Rest – take space to recover
Renew – build resilience, inside and out
We favour quality over quantity, makers over mass production, and brands that back their ethics with action. You’ll find organic staples, therapeutic herbs, and sustainable tools for daily living—all under one roof.
Upstairs, our practitioner room offers tailored support, from nutrition to movement and mental clarity. Downstairs, you’ll find the starting point for your next chapter—whether that’s a new habit, a better meal, or a slower way of being.
Fettle is a basecamp for the everyday explorer.
Come as you are. Leave with what you need.
