Everything you need to know about this product.
What is Skeletal Strength?
Skeletal Strength is a Nature's Sunshine formula designed to nourish the structural system with a blend of key minerals, vitamins, and botanicals. It supports the maintenance and repair of bones, muscles, ligaments, tendons, and skin, while also promoting healthy nervous system function.
What are the key ingredients in Skeletal Strength and what do they do?
The formula features calcium (255 mg) and magnesium (100 mg) to support bone density and muscle function, along with vitamin D3 (3 mcg) to promote calcium absorption and manganese (0.5 mg) to support connective tissue health. It also includes a botanical blend of horsetail, oat straw extract, alfalfa, nettle leaf, turmeric root extract, astragalus root, forskohlii root extract, and ginger rhizome, plus vitamin K2, zinc, copper, and boron — all working together to support structural strength and flexibility.
How do I take Skeletal Strength?
Take 2 tablets with a meal twice daily. At this serving, the 150-tablet bottle provides a 30-day supply. It's a vegetarian-friendly formula, making it a great fit for plant-conscious households.
Who is Skeletal Strength best suited for?
It's ideal for adults looking to support bone density, connective tissue health, flexibility and mobility, and nervous system function. It may also help those concerned about maintaining strong bones as they age. As always, anyone who is pregnant, nursing, or taking medication should consult their healthcare provider before use.
How does Skeletal Strength compare to similar products like Calcium-Magnesium SynerPro or Calcium Plus Vitamin D?
Skeletal Strength goes beyond basic mineral support by combining calcium, magnesium, vitamin D3, vitamin K2, and several other minerals with a diverse botanical blend — making it a more comprehensive structural system formula. If you're looking for straightforward calcium and magnesium support, Calcium-Magnesium SynerPro or Calcium Plus Vitamin D may suit you, while the Structural System 30 Day Program offers a broader packeted approach. Magnesium or Magnesium Complex could be a better fit if magnesium is your primary focus.
