FortiBone — Prime Series for Men 40+

FortiBone — Prime Series for Men 40+

Strong Bones Are Built on Purpose, Not by Chance*

A science backed bone support formula combining Vitamins D3 and K2 to help men after 40 maintain the structural foundation that keeps them active and capable.

Strength is not just muscle. The framework underneath it matters just as much. After 40, your body's ability to absorb and direct calcium where it is needed most can change. Most men do not think about bone health until something forces them to.

FortiBone delivers Vitamins D3 and K2 in a targeted combination.* D3 supports calcium absorption. K2 helps direct that calcium toward your bones and teeth rather than your arteries.* Together, they support the structural wellness that keeps you moving, lifting, and living without limitation.

Think of it as part of a more intentional approach to understanding and supporting your health after 40.

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.
