Subscriptions Options with Shopify for Supplement Company

We used Authorize.net with Shopify for our vitamin company but a lot of banks are declining our transactions. So we moved to Braintree but Shopify does not allow subscriptions with Braintree.

As a vitamin company (regular eye vitamins, nothing special), we are just facing one problem after another and no solutions.

So I am asking what Shopify thinks a vitamin company should do on their platform because you impose a lot of limitations but no solutions.

Thank you
