Brain, focus and eye health in Singapore: a buyer's guide

The supplements people reach for to think clearly and protect their eyes are some of the most over-promised on the shelf. The honest versions are specific about form and dose, and measured about what the evidence supports. Here is how ginkgo, lion's mane, omega 3, and eye nutrients compare, and how to buy each one well.

How to choose a brain or eye supplement

For memory and circulation, ginkgo only works as a standardised extract, so the 24 percent flavone glycoside figure matters more than a big raw milligram number. For focus, lion's mane is the fruiting-body nootropic. For long-term brain and eye health, omega 3 matters for its real EPA and DHA content, and lutein with zeaxanthin matters for eyes that work hard at screens. In every case, read past the headline number to the form and the active amount.
