The details

How this stack works

About this stack

Staying mobile for the long run means supporting bones, cartilage and connective tissue together, not one at a time. The Bone & Joint Stack combines five formulas chosen to support bone density, joint comfort, healthy cartilage and a normal inflammatory response, so you can keep moving the way you want to.*

What's inside

  • Vitamin K2 + D3: Supports bone density & calcium utilisation*
  • Magnesium Glycinate: Supports the bone matrix & muscle function*
  • Ultra Joint Flex: Supports cartilage & joint mobility*
  • Omega-3 Fish Oil: Supports a healthy inflammatory response*
  • Collagen Complex Type I, II, III, V, X: Supports joints, cartilage & connective tissue*

How to take it

Each formula is taken as directed on its own label, most with a meal and a glass of water. Start with the two core products, add the rest once they feel routine, and give the stack a full 8 to 12 weeks. If you are pregnant, nursing, taking prescription medication or have a known medical condition, check with your healthcare provider before starting.

Rooted in nature. Proven by science. Every formula in this stack is manufactured in a US-based, FDA-registered, GMP-certified facility.

What the research says

Bone & Joint Stack

Evidence tier: Moderate to Moderate-to-Strong, by formula

What it is: Five formulas chosen to support bone density, joint mobility, and everyday comfort.

What the research shows: This stack has not been studied as a combination. Three of the five formulas have research that speaks directly to bones or joints:

  • Vitamin K2 + D3 (Moderate-to-Strong): a meta-analysis of 16 randomized trials found vitamin K2 was associated with improved bone mineral density. The trials were in postmenopausal women.
  • Ultra Joint Flex (Emerging to Moderate, by ingredient): supplies the 1,500 mg/day of glucosamine used in the main trials, where results were mixed, plus boswellia, which a meta-analysis of 7 trials found improved joint comfort, stiffness, and function. This research was in older adults with knee osteoarthritis, not healthy joints.
  • Collagen Complex (Moderate, at studied amounts): a 24-week trial in 147 athletes found better joint comfort during activity at 10 g/day. This formula supplies 1.8 g per serving, well below that.
  • Magnesium Glycinate (Moderate): the research we cite is for sleep, not bone.
  • Omega-3 Fish Oil (Moderate-to-Strong, at studied amounts): the research we cite is for blood pressure within the normal range, not joints.

Typical study dose: Study amounts for each formula are listed on its own page. These describe what the studies used, not a recommended amount.

Questions people ask
Can I take all 5 products together?
The stack is designed to be taken together, each product as directed on its own label. Most people split them between breakfast and dinner. If you take prescription medication or have a medical condition, review the stack with your healthcare provider first.
What if I already take one of these?
Keep the one you have and add the rest, or swap it for the Kikaboni version at your next reorder. Do not double up on the same ingredient. The product pages list the amount per serving so you can compare.
How is a stack priced?
A stack costs less than buying the same formulas one by one, and that saving is already in the stack price shown on this page. It goes in your cart as one item and arrives as its own bottles. Because the stack is already discounted, it does not also count toward the 3+ and 6+ formula savings, which apply to formulas bought individually.
Shipping & subscriptions

Each formula in the stack ships as its own bottle from a US-based facility within 1 to 2 business days. Free standard shipping on orders over $100. Subscribe & save is available on every formula and can be changed or cancelled from your account at any time.
