Official product information
MemoFlow contains one 195 mg proprietary blend per 2 ml: grape seed (>95% proanthocyanidins), horse chestnut (>20% aescin), motherwort, hawthorn berry, gotu kola and butcher’s broom extracts. Amounts of each are not listed. The base is water, glycerin and stevia.
The Supplement Facts panel lists one of 195 mg per 2 ml serving. Six herbal extracts are inside, listed in this order. By label rules, ingredients in a blend are listed from most to least by weight, so grape seed is the largest share and butcher’s broom the smallest.
The label does not say how much of each herb is inside.

Two things stand out. First, the amounts. 195 mg shared by six herbs averages about 33 mg each if split evenly, and the real split is not published. Second, the fit. Horse chestnut and butcher’s broom are leg-vein herbs. Hawthorn and motherwort are heart herbs. Grape seed is studied for blood pressure. Only gotu kola is sold for the mind, and the evidence for that is weak.
The idea behind the formula seems to be that better circulation supports the brain. That is a reasonable theory. It is not the same as evidence that these herbs improve memory or focus.
