Before supplements: daily habits
- 01"De-bloating" products like potassium or bromelain only help for a while. They don't fix the root cause.
- 02If you swell because you eat poorly, you may be low on protein (albumin). Start with regular meals.
- 03When you stand or sit for a long time, move your ankles and calves now and then.
- 04If your hands and feet are cold and pale and you get dizzy, get tested for anemia first.
- 05With vein circulation ingredients, many people notice a difference in about a month. For blood vessel recovery, take them steadily for about 6 months.
