Holland & Barrett have discontinued 30mg Ginkgo tablets, leaving 60mg and 120mg on the shelf. No more convenience for a 3 x 30mg dose. I tried a 120 but the increase in tinnitus which happens for me on dose day was uncomfortable so I won't be doing that again. It looks like more is not necessarily better with Ginkgo. And not in one go. Better to string it out over the day.
With a bottle of 120mg tablets to use up I invested in a mortar and pestle. And (through Amazon) a small precision electronic scales. Obtained one for around £30. They are cheaper but I wanted one that measures down to 1mg.
The tablets are tough to break up. So nut cracker used. Success from that. To measure out 30mg of Ginkgo you have to take into account the weight of the binding agent used. A 30mg tablet actually weighs 62mg, and it's 62mg of crushed tablet / powder taken, or thereabout.
