Best Calcium Supplement?

@daisy17 I also started the Seen chew, above the 500mg calcium I make sure I am getting calcium from my diet. I added more D3 and MK7. Not sure if MK 7 is as good as MK 4??. The chews are great, hoping they will work for my supplement. I like getting food based products. Also do weight training and protein.

@lizzie73 Maybe I am reading the Osteo K Minis bottle wrong, but a serving is 2 capsules, twice daily. Each 2 capsules is 22.5 MG so you are taking two doses of 22.5 mg to get 45 mg and not the three 15 mg doses that you reference above. I am surprised Osteo K does not have a dosing that would equal three 15mg doses for the day to match the Japanese study.

@clh222 You can take MK4 along with MK7, which is what I do. I take 180mcg Menaquinone-7 (MK7) - TrueVantage brand and 45,000 mcg (45 mg) of vitamin K2 (menaquinone-4) - Life Extension K2 High Potency brand.

This is what AI Assist says: “Taking vitamin K2 in both MK-4 and MK-7 forms together can be beneficial, as they have different properties and roles in the body. MK-4 has a shorter half-life and is quickly metabolized, while MK-7 has a longer half-life and remains active for a longer period, supporting continuous bone and cardiovascular health. Combining both forms may provide comprehensive support for bone health and calcium metabolism.”

I recently discovered Seen Calcium Chews, which are 100% food based. Each chew contains 500mg calcium, 400IU Vitamin D, plus small amounts of phosphorus and magnesium. The ingredients are organic dates, milk minerals, almonds, milk protein and organic Vitamin D2 mushroom powder. The recommended dose is 1 chew a day. I also take 1/2 dose of a pill form of calcium. I think they taste good.

They are available to purchase from their website: https://www.seennutrition.com/
They are kind of expensive. 30 chews cost $35.00 or $29.75 on auto delivery. 90 chews cost $105.00 or $89.25 on auto delivery.

Hi there,
I wonder if you can possibly share the info you were referring to.
Many thanks in advance

@daisy17 Hi Thank you. Sounds like a really good option particularly when traveling and less likely to take a pill until I get settled. But would need to take 2/day to get just 1000 mg, so yes very expensive.

@loplady You are correct. On Amazon, the label for Osteo-K does show two servings per day, each at 22,500 mcg for a total daily dose of 45,000mcg.

Price wise, the Osteo K supplements are very expensive. A months supply costs $65.95. By comparison, the brand Life Extension Mega Vitamin K has one capsule a day of 45,000 mcg Vitamin K MK-4 priced at $24.03. So buying a supplement with split dosing costs more than twice as much.

I read an article that says it's not necessary to split the dosing of MK-4: "MK4's serum half-life is roughly two hours — and that rapid disappearance from blood isn't a weakness. It's the opposite. Your body pulls MK4 straight into the brain, bone, kidney, pancreas, and reproductive organs. What leaves the bloodstream fastest may be doing the most work. If a nutrient's invisible in a blood draw, it's often because it already reached where it needs to be."

@daisy17 Thanks, I would not buy Osteo K because of the price but have found some other options online. I'm going to give this a try. I think I'll start at 30mg and move up to 45 once I see that I have no issues.
