Supplements for Weight Loss: What Works, What Doesn’t
The weight loss supplement market is buzzing with options—stimulants, appetite suppressants, fat blockers, and metabolism boosters. But do they deliver? Here’s a breakdown of the big players.
Green Tea Extract
- Claim: Boosts metabolism and torches fat.
- Science Says: Modest weight loss is possible, thanks to catechins and caffeine, per a meta-analysis in the International Journal of Obesity.
- Risks: Nausea, constipation, and even liver injury in rare cases—especially with concentrated extracts. It can also mess with meds like nadolol.
- Verdict: A small win, but watch the dose and your liver.
Garcinia Cambogia
- Claim: Blocks fat production and curbs hunger with hydroxycitric acid (HCA).
- Science Says: Evidence is shaky—some studies show slight weight loss, others nada.
- Risks: Digestive woes, headaches, and rare liver damage reports have the FDA on alert.
- Verdict: Risky and unreliable—proceed with caution.
Conjugated Linoleic Acid (CLA)
- Claim: Trims fat and keeps you full.
- Science Says: Might reduce fat mass a bit, but don’t expect miracles on the scale.
- Risks: Upset stomach, insulin resistance, and potential liver issues.
- Verdict: More hype than help—not a game-changer.
Glucomannan
- Claim: Fills your stomach to cut cravings and blocks some fat.
- Science Says: Decent evidence for modest weight loss.
- Risks: Bloating, gas, and a choking hazard if not taken with enough water.
- Verdict: Promising, but use it wisely.
Chromium
- Claim: Tames appetite and burns fat by boosting insulin.
- Science Says: Weak proof—barely moves the needle on weight.
- Risks: Stomach pain, kidney damage at high doses, and drug interactions.
- Verdict: Skip it—benefits don’t outweigh the risks.
Other Contenders
- Chitosan: Fat-blocking claims fall flat with minimal results.
- Caffeine: A slight metabolism kick, but overdo it and feel the jitters.
- Bitter Orange: Might spike your metabolism, but heart risks loom.
- Apple Cider Vinegar: Tiny weight loss perk, at the cost of enamel erosion.
- Alli (Orlistat): A med, not a supplement—works but needs a doctor’s eye.

Supplements for Muscle Gain: Building Strength the Smart Way
Muscle-building supplements promise gains in size, strength, and recovery. Let’s see what holds up.
Whey Protein
- Claim: Fuels muscle growth with a full amino acid profile.
- Science Says: Strong evidence—20-40g daily boosts lean mass and strength with resistance training.
- Risks: Bloating or nausea at high doses; long-term liver/kidney concerns linger.
- Verdict: A solid pick—calculate your needs with our Protein Calculator.
Creatine
- Claim: Pumps up muscle mass and power.
- Science Says: Top-tier evidence—load with 20g/day for a week, then maintain at 3-5g.
- Risks: Water weight and cramps; kidney caution advised.
- Verdict: A proven winner for gains.
Branched-Chain Amino Acids (BCAAs)
- Claim: Boosts muscle size and recovery.
- Science Says: Moderate support—10-14g daily helps, but protein might do the trick alone.
- Risks: Nausea and metabolic quirks at high doses.
- Verdict: Useful, but not essential.
Others to Watch
- Beta-Alanine: Enhances high-intensity performance.
- HMB: Cuts muscle damage, boosts strength in newbies.

India’s Supplement Rules: What You Need to Know
In India, supplements fall under the 2016 FSSAI regulations, requiring licenses and adherence to GMP or ISO 22000 standards. E-commerce sales demand transparency with FSSAI numbers on packaging. Yet, the ICMR warns against overusing protein powders—think kidney strain and sneaky additives. With rising demand, smart choices matter.
