Healthy Bones & Joints

Bone and joint supplements with vitamin D3, K2 MK-7 and magnesium, plus our turmeric, ginger and black pepper tablets.

About our bone and joint supplements

Vitamin D and vitamin K contribute to the maintenance of normal bones, which is why our two D3 and K2 formulas pair them. Choose the Vitamin D3 & K2 tablets (4,000IU D3 with 100µg K2 MK-7) or the vegan D3 & K2 Gummies (4,000IU D3 with 125µg K2 MK-7).

Magnesium also contributes to the maintenance of normal bones and to normal muscle function. Our Magnesium 6-in-1 Advanced Complex provides 485mg elemental magnesium from six forms. You'll also find our Turmeric, Curcumin, Ginger & Black Pepper tablets, a classic Ayurvedic trio in a 90-day supply.

Frequently asked questions

Why take vitamin D3 with K2?

Onyx Nutra Sleep Night Time Gummies jar with valerian root and magnesium

These are non-addictive, tasty and they 120% work. I can sleep without them if I want, and I have noticed they even help straighten out my overall sleep schedule. But when I take 2 before bed… 30 minutes later I can’t keep my eyes open. Guaranteed deep sleep every time 😴🌙✨

Best marine collagen I've used. Mixes well in coffee with a quick stir. Unflavoured really means unflavoured, no fishy aftertaste at all. 9.2g protein per scoop is the macro detail I needed.

85.6% fulvic acid is the strongest I've seen verified. Manuka honey makes the taste manageable, otherwise pure resin can be intense. Sublingual under the tongue is the way. Energy throughout the day is steadier.

Best liquid collagen on the market. The HA, biotin and vitamin C doses are the highest I've come across. Two friends now take this on my recommendation. That's how confident I am in it.
