So far as I know it hasn’t been determined what the one best way for long term reduced-cost use might be, and from individual variability there might well not be one best way.
In general, use absolutely can be only once per day. So there’s an immediate thing that can be done, for sure.
To reduce beyond this, my thoughts on it are that if being systematic there are about 3 ways to do it:
The simplest would be using daily but at substantially reduced dose, for example 2 capsules per day to cut cost in half from using label minimum of 4 capsules per day, or 1 capsule per day to cut cost by 1/4. As opinion, I don’t think this is the way to go. In researching dosage, we saw far superior results at label doses than lower doses, rather than merely proportionally better.
Another way would be to use 4 capsules per day at some number of days per week according to estimated need combined with budgetary constraint. For example, at 3 days per week, a bottle would last nearly 2 months. This method certainly works. How many days per week would have to be chosen individually. If Chris has a recommendation I would go with it rather than mine as he’ll be considering more cases, but my suggestion would be to try 3 days per week and with time see if in your opinion that’s doing what you need, or if it should be increased, or whether you’d like to try reducing further.
Lastly, cycling as needed according to individual judgment. In other words, go without for a while, and when/if finding a need to use again, use at a dosage you like such as 4-6 capsules once per day until feeling you’ve fully improved again.
Whether #2 or #3 is better may depend really on individual style on preference than on anything inherent to the body or the product.
For you, I’d suggest immediately cutting use to once per day, and upon reaching a point where you feel your body function has really improved greatly and there may be no further improvements coming at that dosage, try either of the second two methods to reduce further to save cost.
