Bone & Mineral Support
SummitKai Bone Strength
A calcium complex built for absorption, not just concentration. Calcium Citrate and Calcium Glycinate Chelate work through different uptake pathways, so the formula performs independent of stomach acid and stays gentle on digestion. Vitamin D3 carries that calcium into the bloodstream; Vitamin K2 (MK-7) routes it into bone tissue rather than soft tissue and vessel walls.
Strong, healthy bones. Vitamin D3 helps your body absorb calcium, and vitamin K2 helps direct it to your bones, in a formula that's gentle on digestion.
Per 2 tablets: calcium 500 mg (as calcium citrate and calcium glycinate chelate), vitamin D3 1,000 IU and vitamin K2 (MK-7) 100 mcg.
Two tablets a day. Each bottle of 60 tablets lasts one month.
Adults wanting daily bone support - especially mums and grandparents, and anyone with limited dairy or sun.
Vitamin K2 can affect warfarin and similar blood thinners - talk to your doctor first if you take one. Calcium can reduce the absorption of some medicines (such as thyroid medication and some antibiotics), so take them at different times. Supplements should not replace a balanced diet.

Frequently asked questions
Start with the area you'd like to support. Each SummitKai formula has one focus: Omega 3 One-A-Day for heart and brain health, Omega Balance for all three omegas, Mind Calm for focus and calm sleep, Joint Comfort for joints and mobility, Liver Cleanse for daily liver care, and Bone Strength for bones. Each product page explains who it's for and exactly what's inside. If you take medication, are pregnant or have a health condition, talk to your healthcare professional first.
Many people combine them, because each formula covers a different area. Omega 3 One-A-Day and Omega Balance both contain omega-3, so most people choose one or the other. Bone Strength's calcium can reduce how well some medicines are absorbed, so take them at different times. If you take medication or plan to combine several supplements, check with your healthcare professional.
Every SummitKai product is made in New Zealand. Some ingredients come from wherever the best source is - the omega-3 oil in Omega 3 One-A-Day, for example, comes from Norway - and we tell you where they're from.
We choose forms your body can use and print every ingredient and amount clearly on the label. That means omega-3 in triglyceride form, magnesium as L-threonate and bisglycinate, active vitamin B6 (P5P), and calcium as citrate and glycinate, paired with vitamins D3 and K2. Each formula focuses on one area, so there's nothing in it that doesn't need to be.
Keep the bottle tightly closed in a cool, dry place, away from direct sunlight and heat - a cupboard works better than a steamy bathroom or a sunny windowsill. Keep it out of reach of children, and follow any storage directions printed on the label,
