Weight and metabolism: comparing food supplements
Looking for information on weight management, metabolism or chromium? Compare ingredients, daily servings and warnings. This guide explains what authorised claims about metabolism and normal blood glucose levels mean.
Start with everyday habits
A food supplement does not replace dietary changes, physical activity or an individual assessment of your health. Compare the complete formula alongside any medicines and other supplements you take. A higher dose or a product name alone does not determine the most suitable choice.
Compare the two formulas below as alternatives. This overview is not a recommendation to take both together.
What does a metabolism claim mean?
Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. These claims do not mean lowering elevated blood glucose, treating diabetes or reducing sugar cravings.
Zinc and biotin also contribute to normal macronutrient metabolism. Claims apply to the specified nutrients when their conditions of use are met; they do not automatically apply to the entire blend or establish a weight-loss effect.
Ingredients and daily servings

2 capsules daily · 120 capsules · 60-day supply (approximately 2 months)

Nutrient claims: Chromium, zinc and biotin contribute to normal macronutrient metabolism. Chromium contributes to the maintenance of normal blood glucose levels.

KingSlimming
2 capsules daily · 120 capsules · 60-day supply (approximately 2 months)
A combination of green tea, garcinia, gymnema and black pepper extracts with L-carnitine L-tartrate and chromium. Compare the chromium content, EGCG content and green tea warnings.
Nutrient claims: Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels.
Please note: For adults. Take with food and plenty of water, never on an empty stomach. Do not consume other products containing green tea on the same day. Daily EGCG intake must remain below 800 mg; this is not permission to increase the recommended serving. Not suitable for people under 18 or pregnant or breastfeeding women. Consult your doctor before use if taking medicines or if you have a health condition.
View full ingredients and warnings →What should you check before choosing?
Medicines and overlapping ingredients. Both products contain chromium and gymnema. When combining supplements, add up your total daily intake of vitamins, minerals and other ingredients. More products do not automatically make a better choice.
Ingredient forms matter. The 200 mg of L-carnitine L-tartrate stated for KingSlimming refers to the compound, not the same amount of pure L-carnitine.
Follow the current label. Observe the recommended serving, storage instructions and all restrictions, including those for green tea and EGCG. Ask your doctor or pharmacist about suitability if you have diabetes, take medicines or have another health condition. Do not change prescribed treatment based on this guide.
Frequently asked questions
Do these supplements guarantee weight loss?
No such effect is promised here. The authorised claims for chromium, zinc and biotin concern normal functions, not guaranteed weight loss or fat burning.
Does more chromium mean a better result?
No. A higher dose alone does not establish a better effect or a more suitable choice. Consider total intake and your health.
Does chromium reduce sugar cravings?
That claim is not made here. The authorised claims concern normal macronutrient metabolism and the maintenance of normal blood glucose levels.
How long does one pack last?
Each product contains 120 capsules. At the recommended intake of 2 capsules daily, one pack lasts 60 days, approximately two months.
Can I take them with diabetes medicines?
Consult your doctor first. KINGmetaFIT contains berberine, and both products contain chromium and plant extracts. Supplements do not replace treatment or changes to medicine doses.
Do you use fat-burning claims for plant extracts?
No. Berberine, green tea, garcinia, gymnema and other plant ingredients are described as ingredients. This guide does not use on-hold botanical claims.
Sources and health claims
Composition information is based on KINGmetaFIT product information and the corrected KingSlimming description prepared on 24 October 2026. Always follow the current label and documentation for your pack. Nutrient claims apply only when the relevant conditions of use are met.
No weight-loss, fat-burning, appetite or sugar-craving effects are attributed here to berberine, plant extracts, myo-inositol, L-carnitine L-tartrate or Q10. An on-hold status does not automatically permit use of a claim.
