just found your site per a friend.. I'm looking for more reliable info on osteoporosis and treatments. how do I know how much of my calcium and vit D3 supplements are actually absorbed? Why am I losing bone? How do I determine then build bone strength/quality which is info not related addressed with a DEXA scan?

It appears that there are currently no specific clips from the Huberman Lab discussing osteoporosis and treatments in detail, particularly regarding the absorption of calcium and vitamin D3 supplements, or methods for determining and building bone strength and quality beyond what is covered in a DEXA scan.

For comprehensive information on these topics, I recommend consulting healthcare professionals who specialize in bone health and osteoporosis. They can provide personalized guidance based on your specific health needs and help you understand how to effectively manage and treat osteoporosis.

The absorption of calcium and vitamin D3 and the factors influencing it are not extensively covered in the available clips from the Huberman Lab. However, Andrew Huberman has mentioned the importance of vitamin D3 together with vitamin K2 for aspects of health such as cardiovascular function and regulation of calcium in the body. He noted that even with sufficient sunshine, many individuals may still be deficient in vitamin D3, highlighting the importance of supplementation [1].

For a comprehensive understanding, it's generally recognized that:

• Vitamin D3 enhances calcium absorption in the gut.
• Factors affecting absorption include age, dietary factors, and overall gut health.
• Vitamin K2 is important as it helps direct calcium to the proper areas in the body, preventing it from being deposited where it shouldn't be, such as in arteries and soft tissues.

For more personalized advice and detailed evaluations, regular consultations with healthcare providers and possibly getting blood tests, as suggested for assessing various health metrics, can be beneficial [2].

Bone density loss can be influenced by several non-dietary factors. Key reasons discussed in Huberman Lab include:

1. Hormonal Changes: Throughout one's life, hormonal changes can significantly impact bone density. For example, post-menopausal women face a higher risk of osteopenia and osteoporosis due to decreased levels of estrogen, which is crucial in regulating bone mineral density [1].

2. Medication Use: Certain medications, like inhaled steroids used for conditions such as asthma, can impair bone density during critical developmental windows, presenting significant challenges later in life [2].

3. Physical Activity: Specifically, the type of physical activity matters. Strength training, such as powerlifting, applies shear force from muscles to bones via tendons, which helps improve bone mineral density. This type of mechanical stress on bones is crucial for their health, particularly during the early and peak years of bone development [2].

Understanding these factors can guide interventions that might include hormonal treatments, adjusting medication, and choosing effective forms of exercise to maintain or improve bone health. Always consult with healthcare professionals to tailor approaches based on individual health conditions and needs.
