BONE HEALTH //
So it’s not as “trendy” as gut health, mental health, or menstrual health but boyyyyyy is it important.
If most of us need >1000mg/day of calcium and a cup of full-fat cow’s milk contains around 275 mg of calcium, with an absorption rate of ~30%… where are we to get our calcium, especially if we don’t drink cows milk?
For those who don’t drink cow’s milk (🙋🏼♀️), the highest sources of calcium are: yoghurt, cheese, firm organic tofu, sesame seeds, tahini (sesame paste), almonds, sardines with bones.
Leafy greens like kale and spinach also contain calcium but the absorption is lower due to oxalates.
BUT! Just because we consume calcium, doesn’t mean we absorb it.
Things that can BLOCK calcium absorption:
〰️ Low stomach acid (common, and often due to stress)
〰️ PPIs (e.g omeprazole, Nexium)
〰️ Steroids (e.g prednisone)
〰️ Alcohol, coffee, or tea consumed within 2 hours of calcium
〰️ Clexane (enoxaparin) — increases calcium excretion from bones. I put all my clients taking Clexane on a good quality calcium supplement.
Vitamin D is also crucial for calcium absorption, and most people don’t have enough EVEN if your GP has told you your blood levels are fine. If they aren’t 100-150nmol/L, they are too low. Vitamin D deficiency is extremely common, even in sunnier countries like Australia.
Vitamin K2 also helps with bone health, ensuring calcium is stored in the bones, and not soft tissues like arteries.
And the biggest lifestyle hack of all is weight bearing exercise which improves bone density on a huge scale. Get weight training! Now! Don’t wait until you’re peri-menopausal to start thinking about bone density.
