Vitamin D Deficiency Persists in Summer: Surprising Barriers to Getting Enough

Vitamin D deficiency affects around 60% of people worldwide, even in summer, due to a mix of dietary gaps, limited UVB exposure, aging skin, darker skin tones, and certain medical conditions or medications; experts suggest considering vitamin D3 supplements (often 1,000–2,000 IU daily) under a doctor’s guidance, while being mindful that too much vitamin D can affect kidneys and calcium levels, and that sunscreen and pollution can reduce sun-driven production.

Sunny Season Falls Short: Vitamin D Deficiency Persists Even in Summer, Study Finds

Newcastle University researchers analyzed 299 people and found vitamin D insufficiency remains common even in summer, especially among adults 65+ and individuals with darker skin. Factors include older skin less able to produce vitamin D, higher melanin blocking UVB, and northern latitude limits on summer sun. The findings suggest sun exposure alone may not boost vitamin D for high-risk groups and year-round supplementation is important, though guidelines vary and the study has caveats (all participants started with low levels and supplement users were excluded; funded by BetterYou).

Tiny Molecule, Big Aging Impact: Vitamin B12 and Elder Health

Vitamin B12 is needed in trace amounts but deficiency is common, especially among older adults. Aging can reduce stomach acid and intrinsic factor, impairing B12 absorption from animal foods and causing fatigue, numbness, balance or memory problems. Testing and guidance are advised for those at risk; injections treat confirmed deficiency but don’t boost energy in people with normal B12. Recent research links B12 to mitochondrial energy in muscle and aging, but it does not reverse aging.

Fatigue Could Signal Vitamin D Deficiency, Doctors Say

Vitamin D deficiency is the most common micronutrient shortfall in the U.S., with about 94% not meeting daily needs. Fatigue is the top symptom (often persisting despite sleep), plus sweating, joint/muscle pain, and mood changes. Vitamin D supports bones, calcium absorption, immunity, and inflammation control. NIH recommends 600–800 IU daily, but experts often suggest 1,500–2,000 IU; taking more than 10,000 IU daily can be dangerous. Get your levels checked and follow a personalized plan from a doctor, and remember supplements are not medicines and should be used cautiously in pregnancy, nursing, or for children.

8 Subtle Signs You're Zinc-Deficient, and What They Mean

Zinc is essential for immune function, wound healing, and development; deficiency is uncommon in the U.S. but higher-risk groups include vegetarians/vegans and people with eating disorders, substance use, or GI conditions. The article lists eight signs: slow-healing wounds, hair loss, acne, higher risk of chronic disease, vision changes (age-related macular degeneration), loss of taste or smell, hearing issues, and stunted growth in children. If you notice several signs, consult a clinician, since zinc supplementation can help some symptoms but excessive zinc has downsides.

Vitamin D Deficiency Tied to More Severe Flu Infections

An observational study of 36,258 UK Biobank participants found severe vitamin D deficiency (<15 nmol/L) linked to a 33% higher hospitalization rate for respiratory infections, with each 10 nmol/L increase associated with a 4% drop in hospitalizations; about 18% of Americans have insufficient vitamin D. Experts warn this is not causation, advise testing and doctor guidance before supplementation, and emphasize vaccination and other preventative measures as primary flu defenses.

Unlocking Magnesium's Power for Better Sleep, Anxiety, and Recovery

Magnesium, a vital mineral involved in over 300 bodily functions, is often overlooked despite its importance in promoting relaxation, better sleep, and stress management. Modern lifestyles, poor diet, and stress deplete magnesium levels, leading to symptoms like fatigue, muscle cramps, anxiety, and sleep disturbances. Consuming magnesium-rich foods such as nuts, seeds, leafy greens, and dark chocolate can help, and supplements may be beneficial for some individuals. Simple dietary changes can support overall health and well-being by maintaining adequate magnesium levels.
