FortiBone — Prime Series for Women 40+
Your Body's Foundation Deserves Intentional Support*
After 40, your body begins to shift how it manages calcium. The process is natural, but the consequences matter. Bone health is one of those areas where intentional support today can make a meaningful difference in how you feel and move for years to come.
FortiBone delivers Vitamins D3 and K2 in a complementary formula.* D3 supports your body's ability to absorb calcium. K2 helps direct that calcium to your bones and teeth, supporting structural wellness from the inside.*
This is about taking an active role in your foundation, so your body can keep up with the life you are building.
No major allergens listed. Vegetable capsule. Free from soy, gluten, dairy, and lactose.

FAQ
How are LEAN formulas developed?
Our formulas use carefully selected ingredients at meaningful doses, manufactured in the USA in an FDA registered facility following cGMP standards. We do not claim our finished formulas have been through clinical trials, because they have not. We choose ingredients with published research behind them, at doses consistent with that research, and disclose exactly what is in every bottle.
How do I know which series is right for me?
Prime is formulated for the priorities of life after 40. Platinum is formulated for after 50. The formula is the same within a product; the series reflects the stage of life the guidance is written for. Choose the one that matches where you are.
How should I take this?
Directions are on the product label and in the How to Use section above, since they differ by product. Follow the label.
Is it safe to take with other supplements or medications?
Talk to your doctor or pharmacist before combining supplements, particularly if you take prescription medication. That is true of any supplement, including ours.
What is in it, exactly?
The full Supplement Facts panel and Other Ingredients list are shown on this page. Some formulas use a proprietary blend, where the total is disclosed but individual amounts are not. Where that applies, the panel says so.
Do you have allergens?
Allergen information is listed on every product page. OmegaPure contains fish. FocusFlex contains soy and fish. Some capsules are gelatin based and are not suitable for vegetarians. Check the product page before ordering.
Where do you ship and how long does it take?
We ship across the United States. Orders are fulfilled within one to two business days and typically arrive within three to seven days.
What if it is not right for me?
We offer a 30 day money back guarantee. If it does not suit you, contact Support@LeanNutraceuticals.com and we will make it right.
