Twinings Metabolism, in summary: a peppermint and green tea blend with nettle, ginger and cinnamon, plus added zinc. The name rests on the added zinc, which contributes to the normal processing of carbohydrates, and on a tiny, short lived caffeine effect that does not shift body weight. Drink it as a minty, gently spiced green tea.

Twinings Metabolism is the peppermint and green tea member of the Twinings Superblends range: green tea (36%) and peppermint (36%) with nettle (8%), ginger root (5%), cinnamon bark (3%) and added zinc. It is a pleasant, cooling mint and green tea cup. The product name does some marketing work the cup itself does not, so this page sets the cup and the claim out separately.

What is in the bag

  • Green tea base. Soft vegetal backbone; the source of the caffeine and the catechins (EGCG).
  • Peppermint (36%) and peppermint flavouring. The cooling lead.
  • Nettle (8%). A light, grassy herbal note.
  • Ginger root (5%) and cinnamon bark (3%). A gentle warmth on the finish.
  • Added zinc. 1.5mg per 200ml cup (15% of the reference intake), which is where the name comes from.

The "metabolism" claim, plainly

This is the most oversold claim in functional tea, and a Twinings tea is no exception. Two real but tiny things are happening, and one bigger thing is not.

  • Caffeine and green-tea catechins. A mug of green tea raises energy expenditure by a small, short-lived amount, on the order of tens of kilocalories. Tolerance to caffeine develops quickly, and any rise is dwarfed by what you eat and drink in the same day. Reviews of green tea supplements taken to lose weight conclude the effects are small and not clinically important.
  • Added zinc. Zinc does contribute to the normal processing of carbohydrates, which is what lets the blend carry its name. The contribution is from the added zinc, not the herbs, and a normal diet already supplies it.
  • What it does not do. It does not "burn fat", noticeably speed up the body, or make a difference to body weight. Weight management is set by what you eat, how active you are, and how you sleep; no tea changes that.

What it tastes like

Cool peppermint up front, soft green tea and a light nettle note through the middle, and a gentle ginger and cinnamon warmth on the finish. Pale gold in the cup, clean, drinkable as a daily morning cup. The brewing window is forgiving for green tea standards.

How to brew

  1. 1 bag per 200ml mug.
  2. Freshly boiled water, as the pack directs; if you find green tea bitter, let the kettle stand a minute first (about 80°C).
  3. Steep 3 minutes, then remove the bag; longer turns it grassy.
  4. Drink as is, hot or iced. Honey optional.

Caffeine

Some, from the green tea (36% of the blend), so less than a black tea or coffee. The pack gives no milligram figure, so none is claimed here. Suits morning and early afternoon; skip in the evening if sleep is sensitive.

Cautions

  • Do not treat it as a supplement. If you take a multivitamin or a zinc supplement, account for the added zinc.
  • Pregnancy or medication. Check herbal infusions with a pharmacist, GP or midwife if relevant; keep total caffeine within usual pregnancy limits.
  • Do not use as a weight-loss tool. Real weight management is diet, activity and sleep; no tea changes that.

FAQ

Does this Superblend speed up the body? Only in the trivial sense that any caffeinated drink does for an hour or two; the effect is small, short lived and does not change body weight.

Does it have caffeine? Yes, some, from the green tea base; the pack gives no milligram figure.

Will the added zinc make a difference? Zinc helps the body process carbohydrates normally, which a balanced diet already covers; the tea is a token top up, not a supplement.

Is it a weight-loss tea? No. Twinings does not market it as one in the UK and the evidence does not support it. Treat it as a green tea you like the flavour of.

Curator's note: this Superblend is a nice peppermint and green tea blend wearing a label that promises more than the cup delivers. Drink it for the cool mint and gentle spice, not for any change to your body. Lee, teas.co.uk, Tunbridge Wells.

From the curatorteas · Judge this Superblend on cost per cup, not on its name. Loose peppermint and green usually win, though the Superblend bags sometimes match them.
