Calcium supplement with vitamin D3 and K2, built on hydroxyapatite

Jarrow Formulas Ultra BoneUp is a calcium supplement with vitamin D3 and K2 in tablet form, designed for people who want calcium from a natural source alongside selected micronutrients. The calcium comes from StimuCal, a microcrystalline hydroxyapatite (MCHA) obtained from free-range New Zealand calves. The formula adds vitamin D3, vitamin K2 as MK-7 from fermentation and JarroSil activated silicon. The 240-tablet pack also provides the natural bone proteins of the extract, type I collagen included.

With fast delivery, you receive the 240-tablet pack without long waits.

Follow the dose per serving and the number of tablets shown on the pack label. Do not exceed the recommended daily dose: food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle. It is aimed at active adults who train regularly and want to keep track of their calcium, vitamin D3, vitamin K2 and silicon intake. If you lift or play high-impact sports, check with your doctor or dietitian whether this micronutrient intake suits your diet. If you are pregnant, breastfeeding or on medication, ask your doctor before use. Keep out of the reach of children.

Is Ultra BoneUp suitable for vegetarians and vegans?

No. StimuCal calcium comes from calves, so the product contains animal-derived ingredients. If you follow a plant-based diet, choose a mineral or plant-based alternative.

What is the difference between hydroxyapatite and calcium carbonate?

Calcium carbonate is a simple mineral salt. StimuCal microcrystalline hydroxyapatite is a naturally sourced form of calcium that also brings bone proteins, such as type I collagen. Always compare the calcium amounts shown on the label.

Can I take it with other supplements?

Check the label for the calcium, vitamin D3 and vitamin K2 already in this product and in the others you use, so that you stay within the recommended daily dose. If you have doubts or are on medication, talk to your doctor.
