Cracked heels, also known as heel fissures, are a common skin condition caused by dryness, pressure, and insufficient hydration. These cracks can become painful and prone to infection if left untreated, significantly affecting mobility and quality of life. While topical treatments such as moisturizers and balms are widely used, addressing the root causes of cracked heels often requires a more holistic approach.
Magnesium glycinate, a highly bioavailable form of magnesium, has emerged as a promising aid in healing cracked heels by restoring hydration, boosting skin repair, and addressing underlying deficiencies. This article explores the science behind magnesium glycinate’s role in managing cracked heels and provides practical guidance for incorporating it into a care regimen.

Understanding Cracked Heels
Cracked heels develop when the skin around the heel becomes excessively dry and loses its elasticity. Over time, the skin thickens and forms calluses, which can split under pressure. Common symptoms include visible cracks, redness, peeling, and discomfort when walking or standing. In severe cases, bleeding and infection may occur, necessitating medical attention.
Prevalence and Risk Factors
- According to a 2019 report published in the Journal of Clinical Dermatology, approximately 20% of adults experience cracked heels, with higher prevalence among older individuals, people with diabetes, and those who frequently walk barefoot.
- Environmental factors such as low humidity, cold weather, and prolonged exposure to water can exacerbate the condition, as can underlying health issues like hypothyroidism or eczema.
Effective management of cracked heels requires not only symptomatic relief but also addressing the root causes, including poor skin hydration and compromised skin repair mechanisms.
The Role of Magnesium in Skin Health
Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body, including processes critical to skin repair and hydration. Its role in promoting cellular regeneration, reducing inflammation, and improving moisture retention makes it particularly relevant for individuals with cracked heels.
Key Mechanisms of Action
- Hydration and Moisture Retention: Magnesium helps maintain the skin’s water balance by supporting the synthesis of natural moisturizing factors (NMFs) such as hyaluronic acid. NMFs attract and retain water, preventing the skin from becoming excessively dry.
- Collagen Production: Collagen is a structural protein that provides strength and elasticity to the skin. Magnesium is a cofactor for enzymes involved in collagen synthesis, promoting the repair of damaged skin.
- Anti-Inflammatory Effects: Cracked heels often involve localized inflammation, particularly when the fissures deepen. Magnesium modulates inflammatory pathways, reducing redness and irritation.
- Cellular Regeneration: Magnesium facilitates the replication and differentiation of keratinocytes, the primary cells in the epidermis. This supports the healing of cracks and prevents further damage.
- Barrier Function Support: Magnesium strengthens the skin’s lipid barrier, reducing trans-epidermal water loss (TEWL) and enhancing the skin’s ability to protect against external irritants.
Why Magnesium Glycinate?
Magnesium glycinate is a chelated form of magnesium in which the mineral is bound to glycine, an amino acid. This unique structure enhances magnesium’s absorption and bioavailability, making it one of the most effective forms of magnesium supplementation.
Benefits of Magnesium Glycinate for Cracked Heels
- Enhanced Absorption: Magnesium glycinate is better absorbed compared to other forms such as magnesium oxide, ensuring that therapeutic levels of magnesium reach the skin and other tissues (Schuette et al., 1994).
- Skin-Calming Effects: Glycine, a component of magnesium glycinate, has additional soothing and anti-inflammatory properties that complement magnesium’s role in healing cracked heels.
- Reduced Gastrointestinal Side Effects: Unlike magnesium citrate or sulfate, glycinate is less likely to cause diarrhea, allowing for consistent supplementation.
- Support for Sleep and Stress Management: Stress and poor sleep can impair skin healing. Magnesium glycinate promotes relaxation and improves sleep quality, indirectly supporting skin repair processes.
Clinical Evidence: Magnesium and Skin Repair
While specific studies on magnesium glycinate and cracked heels are limited, broader research on magnesium’s role in skin health provides compelling evidence.
- Magnesium Deficiency and Skin Conditions: A review in Nutrients highlighted the link between magnesium deficiency and various skin disorders, including dryness, inflammation, and delayed wound healing. The authors emphasized that magnesium supplementation could enhance skin hydration and repair (Zhang et al., 2018).
- Topical Magnesium for Hydration: A study published in International Journal of Dermatology found that magnesium-rich Dead Sea salt baths improved skin hydration and reduced roughness in individuals with dry skin conditions (Proksch et al., 2005).
- Magnesium and Collagen Synthesis: Research in Biochemistry Research International demonstrated that magnesium enhances the activity of enzymes critical for collagen production, supporting the repair of damaged skin (Rosanoff et al., 2012).
- Magnesium’s Anti-Inflammatory Effects: A study in Inflammation Research found that magnesium supplementation reduced markers of inflammation such as C-reactive protein (CRP), potentially alleviating irritation in cracked heels (Zheltova et al., 2016).
These findings underscore magnesium’s potential to address the key factors contributing to cracked heels, including dryness, inflammation, and impaired repair mechanisms.
Practical Applications for Healing Cracked Heels
Integrating magnesium glycinate into a comprehensive skincare routine can accelerate the healing of cracked heels and prevent recurrence. Below are practical strategies for incorporating this supplement:
1. Daily Magnesium Glycinate Supplementation
- Adults typically require 310–420 mg of magnesium daily, depending on age and sex (National Institutes of Health, 2021). Supplementation with magnesium glycinate can help meet these needs while targeting skin repair and hydration.
- Consistency is key, as magnesium levels take time to stabilize in the body.
2. Topical Magnesium Applications
- While oral magnesium glycinate provides systemic benefits, topical magnesium formulations (e.g., creams or oils) can deliver localized hydration and anti-inflammatory effects to the heel area.
3. Pairing with Nutritional Co-Factors
- Combining magnesium glycinate with other skin-supporting nutrients, such as vitamin C (for collagen synthesis) and omega-3 fatty acids (for inflammation reduction), can enhance results.
4. Hydration and Moisturizing
- Use thick emollients or balms containing urea or shea butter to lock in moisture. Magnesium glycinate’s systemic benefits complement these topical treatments by improving overall skin hydration.
5. Exfoliation and Skin Barrier Repair
- Gentle exfoliation removes dead skin cells and enhances the penetration of moisturizers. Avoid harsh scrubbing, which can worsen fissures.
- Look for products containing ceramides to strengthen the skin barrier.
Addressing Underlying Causes
Cracked heels are often a symptom of broader health issues. Magnesium glycinate can help address several underlying factors:
- Diabetes and Peripheral Neuropathy: Magnesium supports nerve health and glycemic control, making it particularly beneficial for individuals with diabetes who are prone to foot complications.
- Hypothyroidism: Hypothyroidism reduces skin turnover and hydration. Magnesium glycinate aids thyroid function and may indirectly improve skin health.
- Stress and Poor Circulation: Chronic stress and impaired blood flow to the feet can delay healing. Magnesium glycinate’s calming and vasodilatory effects help counteract these factors.
Safety and Considerations
Magnesium glycinate is generally safe and well-tolerated. However, excessive intake can cause mild side effects such as nausea or abdominal cramping. Individuals with kidney disease or those taking medications that affect magnesium levels (e.g., diuretics) should consult a healthcare provider before supplementation.
Drug Interactions
- Magnesium can interfere with the absorption of certain medications, including antibiotics and bisphosphonates. It is best to take magnesium glycinate at least two hours apart from these drugs.
Future Research Directions
While existing studies highlight magnesium’s role in skin health, further research is needed to explore:
- The specific effects of magnesium glycinate on cracked heels and other dry skin conditions.
- Optimal dosing strategies for skin repair.
- Synergistic effects of magnesium with other skin nutrients.
- Long-term benefits of combining systemic and topical magnesium therapies.
These investigations could solidify magnesium glycinate’s role as a cornerstone therapy for cracked heels.
Conclusion: Magnesium Glycinate for Healing Cracked Heels
Magnesium glycinate offers a multifaceted approach to healing cracked heels by restoring hydration, boosting collagen production, and reducing inflammation. Its systemic benefits complement topical treatments, addressing both the symptoms and underlying causes of heel fissures. With its superior bioavailability and minimal side effects, magnesium glycinate provides a safe and effective solution for individuals struggling with dry, damaged feet.
By integrating magnesium glycinate into a holistic skincare routine, individuals can accelerate healing, prevent recurrence, and enjoy healthier, more resilient skin. For best results, consult a healthcare provider to tailor supplementation to individual needs and ensure long-term success.
