MyProtein Thermopure Review — Is It Worth It?

fat burner are the most overhyped category in sports nutrition, and MyProtein Thermopure is a more honest product than most. The effects are modest, the ingredients are transparent, and the price is low. It won't transform your body — nothing in a capsule will — but as a mild metabolic support tool during a calorie deficit, it's a reasonable addition.

What Is It?

Thermopure is MyProtein's caffeine and green tea-based thermogenic supplement in capsule form. It's positioned as a fat-loss support product to be used alongside a calorie-controlled diet and exercise programme — not as a standalone weight-loss solution. This honest positioning sets it apart from some competitors.

Ingredients & Nutrition

Per 2-capsule serving: 200mg caffeine, 200mg green tea extract (standardised to 45% EGCG), 100mg L-carnitine, and a B vitamin complex including B6 and B12. No calories.

The formula is straightforward and the key compounds are at reasonable doses. Green tea extract at 200mg with EGCG standardisation has reasonable evidence for modest thermogenic effect. L-carnitine at 100mg is below the doses used in most research (typically 500mg–2g), though it provides some support for fat oxidation. The B vitamins are standard inclusions for energy metabolism support.

Taste & Mixability

Capsule form — no taste or mixing required. Take 2 capsules before training or in the morning with breakfast. The caffeine content means it's best avoided within 6 hours of bedtime.

Effectiveness

Be realistic: thermogenic supplements provide modest assistance to a well-structured diet and training programme — they do not cause fat loss in the absence of a caloric deficit. Thermopure's caffeine content provides a genuine, modest metabolic boost (approximately 3–4% increase in resting metabolic rate for several hours after consumption). The green tea EGCG compounds add a small additional thermogenic effect.

Studies suggest caffeine and green tea together may increase fat oxidation by around 10–16% over control in calorie-restricted subjects. That is meaningful — but it's a percentage of a small number, and the effect diminishes with habitual caffeine use.

Value for Money

At £14.99 for 90 capsules (45 servings), the cost is approximately £0.33 per serving. That's the most affordable option in this comparison. Given the modest effects of any fat burner, keeping costs low makes sense — there's no premium formula that meaningfully outperforms this.

Verdict

Thermopure is what a responsible fat burner looks like — modest claims, honest ingredients, low price. The effect is real but small, and the product is best viewed as a minor tool in a broader fat-loss strategy rather than a solution. If you want caffeine and green tea in a capsule at the cheapest possible price, this delivers. Manage expectations and keep your diet in order.
