🟥 ⚠️ Supplements to Skip (Mostly)

❌ Fat Burners

  • Often contain unregulated stimulants.

  • No scientific backing for "melting fat."

Risks:

  • Increased heart rate 💓

  • Anxiety and sleep disruption

  • FDA has banned several ingredients over time

❌ Detox Teas & Cleanses

  • Kidneys and liver already detox the body.

  • No medical necessity unless under supervision.

Third-party view:

❌ BCAAs (Branched-Chain Amino Acids)

  • Popular in gyms, but most diets already provide enough.

  • Whole protein sources are more effective and cheaper.

Better option: A balanced meal with protein-rich food 🥚
