Osteoguard Advance is a bone health mix that supports healthy bones by delivering calcium, magnesium and vitamins K2 and D3 in a balanced blend.

Lamberts, a UK based specialist in targeted health nutrients, brings decades of experience and strict quality standards to Osteoguard Advance.

Benefits & Features:
- Osteoguard Advance supports bone health with a balanced blend.
- Calcium to magnesium balance promotes steady bone metabolism and helps the body place calcium where it belongs.
- Vitamin K2 MK-7 directs calcium to bone tissue rather than soft tissues.
- Vitamin D3 supports calcium absorption, helping create stronger bones and a healthier skeleton.
- High potency formulation with a thoughtful 2:1 calcium to magnesium ratio maximises absorption and supports long term bone health, while staying gentle on digestion every day.
From its UK roots, Osteoguard Advance benefits from Lamberts' long standing commitment to quality and targeted nutrition. The brand is known for vegetarian friendly formulations and transparent sourcing, including MK-7 vitamin K2 derived from chickpea fermentation, which is a no brainer. Lamberts has earned trust across Europe through rigorous manufacturing standards and specialist lines in bone health and cardiovascular support. For shoppers comparing options, some blends use magnesium glycinate; ours relies on a robust magnesium mix to support absorption. Lamberts also offer liver supplements as part of their health portfolio, which is really quite good for those building a wider wellness routine.

The Active Ingredient Is: Calcium (Carbonate and Citrate Blend)
Calcium is a mineral essential for the maintenance of normal bone structure and bone metabolism. In this product, calcium is supplied as a blend of carbonate and citrate forms to support its functional role in skeletal health.
This formula also includes other nutrients, notably magnesium, vitamin K2 as MK-7 and vitamin D3, which help support calcium utilisation and bone health processes.
What Does Calcium Do?
Calcium plays a role in maintaining normal bones and teeth and supports skeletal function as part of a balanced diet and healthy lifestyle. It works alongside magnesium, vitamin D3 and vitamin K2 to support calcium deposition and bone metabolism in line with EFSA guidance.
