Why can individual Nattokinase + Vitamin D3 tablets crumble, and how should I use them then?

Our nattokinase tablets are 100% free from additives. Because we intentionally avoid binders, oils, and other stabilizers, the tablets are more brittle than conventional products.

The original soybeans from Japan are naturally low in moisture and do not contain a natural binding agent. Transport can also involve strong vibrations that we cannot control. As a result, some tablets in the bottle may break.

To keep the risk as low as possible, we continuously check tablet hardness and fill the product into sturdy plastic bottles with a special closure. Despite these measures, a small proportion of crumbly tablets cannot be completely avoided. Natural purity takes priority over absolute break resistance.

What matters is this: the efficacy remains unchanged. The enzyme nattokinase and accompanying compounds such as spermidine, vitamin B9, isoflavones, probiotic cultures, phosphorus, and iron are just as active in the powder as in an intact tablet.

If a tablet has broken, simply stir a level teaspoon of the powder — equivalent to one tablet — into a glass of water.
