Two bottles: lowest current total spend
The current 2-bottle package is reported at $79 per bottle, or $158 total, with shipping added. At the label serving of two capsules per day, two 60-capsule bottles correspond to about 60 servings total.
This option requires less upfront spending than the larger packages, but its per-bottle price is currently the highest.
Three bottles: middle package
The current 3-bottle package is reported at $69 per bottle, or $207 total, with free U.S. shipping. Seller materials also advertise two digital bonus guides with qualifying packages.
For buyers comparing cash outlay with unit price, this option sits between the two- and six-bottle packages.
Six bottles: lowest unit price
The current 6-bottle package is reported at $49 per bottle, or $294 total, with free U.S. shipping and the same advertised bonus guides.
The unit price is lower, but the upfront commitment is $87 more than the three-bottle package and $136 more than the two-bottle package.
How to make the comparison
Calculate the total you are comfortable spending, confirm shipping, and remember that package quantity does not increase evidence for effectiveness. More bottles are simply more product.
If you are uncertain about ingredients or safety, solve that uncertainty before optimizing package price.
