Overview
NOW Foods' calcium citrate powder delivers a highly bioavailable form of calcium in an 8-ounce, unflavored, kosher and vegan powder meant to be mixed into food or drink for bone health support.
Calcium citrate is generally easier for the body to absorb than calcium carbonate, particularly when taken without food, which is why NOW frames this as a bioavailable option. Powder format lets buyers control dosage and mix it into smoothies or other drinks rather than swallowing tablets.
- 8 ounce powder container
- Calcium citrate for bioavailability
- Kosher and vegan formulation
- Supports bone health
Who it's for
Fits people who want a calcium supplement that mixes into food or beverages and prefer citrate over carbonate for absorption reasons. Less suited to anyone who wants a grab-and-go tablet or capsule format.
Strengths and trade-offs
Drawn from this product's published specifications.
- Highly bioavailable calcium citrate form
- Unflavored, mixes into food or drinks
- Kosher and vegan
- Requires measuring doses rather than pre-portioned pills
- No flavor to mask any aftertaste
Performance notes
Being unflavored, the powder blends into juice, water or food without altering taste much, though texture can be slightly gritty depending on dissolution. Calcium citrate's absorption advantage over other calcium forms is its main functional distinction here.
