An oncologist notes that while most dietary supplements aren’t harmful, some—particularly antioxidants for immunocompromised patients—should be used with caution. There’s no clear evidence that supplements prevent cancer, and their use can raise safety and interaction concerns with cancer therapies; patients should discuss any supplement plan with their clinician and be mindful of regulatory and safety considerations.
Samantha Ruth Prabhu discussed perimenopause and brain fog with nutritionist Rashi Chowdhary, who suggested starting the day with healthy fats, adding lion's mane mushroom, and using smart supplements like creatine and CoQ10 to improve cognitive function. Expert fact-checking by Dr. Ravina Patel highlighted the importance of a balanced diet and clarified that some claims, like the efficacy of lion's mane mushroom, lack sufficient scientific evidence, emphasizing sustainable and affordable health practices.
The article discusses the rising popularity of protein powders driven by social media and consumer demand, highlighting that while protein is essential for health, most people can meet their needs through whole foods rather than supplements, which can sometimes contain unsafe levels of contaminants like lead. Experts recommend focusing on high-quality, whole food sources of protein and consuming adequate amounts at each meal, especially for children, older adults, and athletes, rather than relying heavily on protein powders.
Sea moss, a nutrient-rich seaweed popularized by social media influencers, is traditionally used for its potential health benefits, but scientific evidence supporting these claims is limited. While it contains beneficial nutrients like fiber, vitamins, and minerals, concerns about heavy metal contamination and excessive iodine intake suggest moderation and caution, especially for certain groups. Experts recommend incorporating sea moss as part of a balanced diet rather than relying on supplements or trendy products.
The article critiques Jessie Inchauspé, the 'Glucose Goddess,' for promoting questionable blood sugar management hacks, endorsing unnecessary continuous glucose monitoring for healthy individuals, and selling unproven supplements, all while lacking proper medical credentials and relying on weak scientific evidence.
A study suggests that omega fatty acids, found in fish or supplements, may help protect women from Alzheimer's disease by influencing lipid composition, though further research is needed to confirm this potential benefit.
Research indicates that omega-3 fatty acids, particularly EPA and DHA found in fish oil, can significantly improve depressive symptoms, though they may not prevent depression. Consuming 1-1.5 grams daily through high-quality supplements or fatty fish like salmon is recommended for mental health benefits.
A study suggests that combining omega-3 supplements with weightlifting can improve heart and brain health, as well as physical performance, in healthy young men, though further research is needed to confirm if these benefits extend to the general population.
The article debunks common vegan food myths, emphasizing that not all vegan foods are healthy, plant-based meat substitutes can be highly processed, almond milk isn't the best dairy alternative nutritionally, increasing fiber suddenly can cause digestive issues, plant proteins vary in quality, and vegans may need supplements for certain nutrients. It encourages curiosity and informed choices for a balanced vegan lifestyle.
A recent study published in JAMA Internal Medicine suggests that vitamin K2 may help reduce nocturnal leg cramps, which are common involuntary muscle contractions occurring during sleep. The study involved participants over 65 who experienced night cramps, with those receiving 180 micrograms of vitamin K2 showing a significant decrease in cramps compared to a placebo group. Vitamin K is essential for bone health and blood clotting, and is found in foods like dark leafy greens and fermented products. However, individuals on blood thinners should consult a physician before increasing vitamin K intake.
A study by the University of Georgia suggests that omega-3 and omega-6 fatty acids, found in fish oil and certain plant-based foods, may reduce the risk of several types of cancer, including colon, stomach, and lung cancers. The research, which analyzed data from over 250,000 participants in the UK Biobank, found that higher blood levels of these fatty acids were associated with a lower incidence of cancer. While the findings support increased intake of these unsaturated fats, further research is needed to understand their effects across different populations and cancer types.
Oatzempic, a viral TikTok trend, is being promoted as a natural alternative to the weight loss drug Ozempic. It involves consuming a blend of oats, water, and lime juice as a meal replacement, followed by intermittent fasting. While oats are nutritious and can aid in weight loss by reducing calorie intake, Oatzempic lacks the scientifically proven effects of semaglutide, which targets GLP-1 receptors to significantly reduce appetite and improve metabolic health. The trend may not support sustainable weight loss, unlike a balanced diet incorporating oats in a more traditional manner.
A new study published in BMJ Medicine links regular fish oil supplement use to a higher risk of first-time heart problems like atrial fibrillation and stroke in otherwise healthy individuals. However, for those with existing heart disease, fish oil may reduce the risk of progressing to more severe cardiovascular events. The study, based on data from the UK Biobank, highlights the need for further research to understand the specific impacts and mechanisms of fish oil supplements on heart health.
The Council for Responsible Nutrition has proposed new packaging guidelines for melatonin supplements, following a spike in emergency room visits among children who ingested the product unsupervised. The guidelines focus on formulation, labeling, and packaging, with specific measures for gummy supplements to protect children. The voluntary guidelines aim to address mislabeling and the potential dangers of melatonin consumption, particularly in gummy form, and urge manufacturers to adopt them within specified timeframes.
Dietary supplements, including popular ones like fish oil and vitamin D, can be harmful if taken in excessive amounts. Overdosing on magnesium can lead to symptoms like sleepiness, loss of reflexes, and even paralysis and death, while too much vitamin C can cause tiredness, kidney problems, and vitamin B12 deficiencies. Excessive vitamin D intake can increase blood calcium levels, leading to symptoms like conjunctivitis, pain, fever, and vomiting, especially for those with kidney disease. The main risk associated with fish oil supplements is the potential presence of pollutants like heavy metals, although processing and purification typically remove these toxins. It's important to be cautious and consult a healthcare professional before taking dietary supplements.
