Guarana

别名: Paullinia cupana, guarana powder

Guarana is a South American vine whose seeds contain more caffeine than coffee beans, along with theobromine and tannins. Its effect on alertness and performance mainly reflects its caffeine content.

用途

剂型及区别

何时服用

In the morning or before training; not later than 6–8 hours before bed.

适合搭配

L-theanine for a 'smoother' energy, plenty of water.

不宜同服 / 需错开

Do not combine with coffee, energy drinks or other caffeine sources without adding up the total dose; keep a gap from iron and thyroid medicines.

注意事项

During pregnancy and breastfeeding, limit total caffeine. With high blood pressure, heart rhythm disorders, anxiety, insomnia, kidney or liver disease, or if you take medicines (especially stimulants, some antidepressants, asthma medicines), consult your doctor.

安全性

EFSA considers up to 400 mg caffeine per day and up to 200 mg at once safe for healthy adults; up to 200 mg per day during pregnancy. Add up all caffeine sources and do not exceed the label dose.

实用建议

Look for products that state caffeine in mg per dose – otherwise you cannot tell how much you are really taking.
