How much of each ingredient is in one capsule?
Only the two minerals have exact amounts. Blend figures are the most each could weigh by its place.
| Ingredient | Place | Per capsule | Research note |

| Chromium | Own line | 50 mcg | About 143% of today's DV (NIH ODS, Chromium) |
| Alpha-lipoic acid | 1 of 8 | Up to 276 mg | Studies used 600 to 1,800 mg a day (MSKCC, Alpha-lipoic acid) |
| Green tea extract | 2 of 8 | Up to 138 mg | About 1 kg beyond placebo (NIH ODS, Weight-loss supplements) |
| Milk thistle | 3 of 8 | Up to 92 mg | No weight data (NCCIH, Milk thistle) |
| Berberine HCl | 4 of 8 | Up to about 69 mg | Weight effects mainly above 1 g a day (NCCIH, Berberine and weight loss) |

Blend math
Why does the label hide the blend amounts?
Because the law allows it. A blend needs only its total weight and its ingredients listed heaviest first (FDA, Labeling guide ch. IV). That order still sets a ceiling: the ingredient in place 4 can weigh at most a quarter of 276 mg.
- 1Alpha-lipoic acid35 to 276 mgListed first: the largest share, at least about 35 mg
- 2Green tea leaf extract (80% catechins, 50% EGCG)0 to 138 mgAt most about 110 mg catechins and 69 mg EGCG
- 3Milk thistle seed extract (80% silymarin)0 to 92 mg
- 4Berberine HCl (97% berberine)0 to 69 mgStudies of weight used 300-1,500 mg a day
- 5Resveratrol (Polygonum cuspidatum root extract 200:1)0 to 55 mg
- 6Cayenne fruit (40,000 H.U.)0 to 46 mgH.U. is a heat rating, not a capsaicin amount
- 7Korean ginseng aerial extract (8% ginsenosides)0 to 39 mg
- 8Banaba leaf extract (2% corosolic acid)0 to 34 mgAt most about 0.69 mg corosolic acid
Blend ingredients are listed from heaviest to lightest (FDA, Labeling guide ch. IV), so the ingredient in place k can weigh at most 276 ÷ k mg. That is our math from the label, not a lab test; the real amounts are probably lower. Zinc (5.5 mg) and chromium (50 mcg) sit outside the blend with their own amounts.
True amounts are probably lower. The biggest gap is berberine; see the berberine profile.

FAQ
Slim Metrix ingredients: common questions
Which ten ingredients does Slim Metrix list?
Zinc 5.5 mg, chromium 50 mcg and a 276 mg blend led by alpha-lipoic acid and green tea extract. Milk thistle, berberine HCl, resveratrol, cayenne, Korean ginseng and banaba follow, in that order.
Why does the Slim Metrix graphic show only six ingredients?
The graphic is a summary. The label adds alpha-lipoic acid, listed first, plus cayenne, ginseng and banaba. Trust the label.
Is the Slim Metrix capsule shell plant-based?
The capsule shell is hypromellose, a plant-based material, and a brand badge says vegetarian. No certifier is named, so read the bottle you receive if this matters to you.
Does Slim Metrix contain stimulants?
No stimulant amount is listed. Green tea has some natural caffeine and cayenne is a hot pepper, but no figure is printed for either.
Are the Slim Metrix ingredients natural?
Mostly plant extracts plus two mineral salts. Natural does not always mean safe (NCCIH, Using supplements wisely).
Which Slim Metrix ingredient has the best evidence for weight?
None is strong. Chromium and green tea each show about 1 kg or less beyond placebo, and berberine's data come from doses far above what one capsule can hold.
