Abstract:
Background: Bone tissue undergoes continuous remodeling, and imbalances in this process can lead to osteometabolic disorders, such as osteoporosis. Thus, bioactive compounds, like lycopene (LYC), have been investigated for their potential protective effects in bone health. This systematic review (SR) aimed to evaluate the effects of LYC supplementation on bone tissue. Methods: The SR was registered in PROSPERO (CRD42023417346) and followed the PRISMA guidelines. A comprehensive search was conducted in electronic databases up to May 2025. Two independent reviewers selected clinical trials and animal studies evaluating the effects of LYC supplementation in bone tissue. Methodological quality and risk of bias were assessed using the Cochrane Risk of Bias tool for randomized controlled trials, the Newcastle-Ottawa Scale for non-randomized clinical studies, and the SYRCLE tool for animal studies. Results: A total of 21 studies met the eligibility criteria, consisting of 6 clinical trials and 15 studies in animal models. LYC supplementation promotes an increase in bone mineral density, preserves trabecular microarchitecture, stimulates osteoblastic activity, and inhibits osteoblast apoptosis. Conclusions: LYC supplementation promotes beneficial effects on both the formation and preservation of bone tissue, suggesting that this carotenoid may represent a potential adjuvant strategy in the management of osteometabolic disorders.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
