Pros & Cons
Pros
- Lab result matches label perfectly (385mg vs 385mg claimed)
- At least acknowledges 'buffered' on the packaging — more honest than some
- Added turmeric with BioPerine for anti-inflammatory support
- Stylish blue pouch with strong wellness community following
- Multi-form approach covers different magnesium benefits
Cons
- Most expensive product in our test at 86p per gram of elemental magnesium
- Uses oxide buffering — 'buffered' is printed on the bottle
- Despite the premium price, contains the cheapest form of magnesium
- Turmeric dose is likely sub-therapeutic compared to dedicated products
- Only 30 servings per pouch (90 tablets, 3 per day)
- Loaded with inactive ingredients: silicon dioxide, magnesium stearate, dicalcium phosphate, microcrystalline cellulose, and a clear coating

Ingredient Quality
The Free Soul nutritional label reveals something most consumers would miss. The ingredient list explicitly states each magnesium form is '30% Buffered' — meaning 30% of each compound is magnesium oxide. Let's break down what's actually in the 3-tablet serving:
The total magnesium compounds are 1,283mg (not the 1,983mg on the front of the pouch — that appears to include turmeric and fillers in the total). The breakdown: 600mg bisglycinate (30% buffered), 483mg citrate (30% buffered DC), and 200mg malate (30% buffered). With 30% of each form being oxide, roughly 385mg of the 1,283mg blend is actually oxide — and that oxide is responsible for an estimated 60% of the 385mg elemental magnesium figure.
On top of the magnesium, there's 40mg of turmeric extract (50:1 concentration) and 10mg of black pepper extract. The formula also includes silicon dioxide, magnesium stearate, dicalcium phosphate, and microcrystalline cellulose as fillers.
Value Analysis
At £9.99 for 30 servings, Free Soul is reasonably priced. But when you consider that roughly 60% of the elemental magnesium comes from the cheapest, least absorbable form (oxide at 4% absorption), the actual usable magnesium per serving drops considerably. The turmeric dose is 40mg of 50:1 extract — small but concentrated. However, dedicated turmeric supplements typically provide 500–1,500mg of curcumin per serving.
Effectiveness
The unbuffered portions of the glycinate, citrate, and malate will provide some benefit. But an estimated 231mg of the 385mg elemental comes from oxide, which at 4% absorption delivers only about 9mg of absorbed magnesium. The remaining 154mg from the genuine forms at 30-45% absorption delivers roughly 50-70mg. Total absorbed: approximately 60-80mg from a label claiming 385mg.
Who Is This Best For?
Free Soul appeals to wellness-focused consumers drawn to the brand's lifestyle positioning. The Instagram-friendly blue pouch and turmeric addition are clear marketing plays. At least they disclose the buffering in the ingredient list — but it takes label literacy to spot '30% Buffered' and understand what it means. Most consumers won't.

Free Soul 4-in-1 Magnesium Glycinate + Turmeric FAQ
What does 'buffered' mean on the Free Soul label?
In supplement terms, 'buffered' typically means magnesium oxide has been added to the formula. Oxide is cheap to produce and is 60% elemental magnesium by weight, which inflates the headline number on the label. However, oxide has one of the lowest absorption rates of any magnesium form — roughly 4% compared to glycinate's 40–50%.
Is the turmeric in Free Soul effective?
The inclusion of turmeric with BioPerine (black pepper extract for absorption) is a smart concept, but the dose is likely sub-therapeutic compared to a dedicated turmeric supplement, which typically provides 500–1,500mg of curcumin per serving. It's a marketing addition rather than a clinically meaningful dose.
