It seems more of us are turning to supplements for a range of issues—from sleep to cognitive functions and skin health. Recent research by Mintel indicates that around 70% of adults in the UK have taken vitamins, minerals, or other supplements, contributing to a market that exceeds £600 million per year. It’s primarily middle-aged and older individuals, who are concerned about aging, that are driving this trend of daily supplementation.
Yet, the question remains: do we actually need these supplements to maintain good health? Recently, Dr. Xand van Tulleken, a public health expert, shared his worries regarding the overwhelming and often misleading variety of health supplements being marketed as daily necessities by social media influencers. He pointed out their potential for high profits, easy distribution, and lax regulations. While some may indeed benefit from specific supplements temporarily, they are not universally effective for everyone. He urged people to seek advice from trusted sources, like the NHS, instead of relying on social media.
So, what should we consider taking? If you’re unsure, it’s wise to consult a GP or pharmacist before trying any new supplement, especially if you’re already on medication or have health concerns. Here’s a rundown of some common supplements and what adults should know before diving in:
Vitamin D
Crucial for bones, teeth, muscles, and immune health, vitamin D also aids in the absorption of calcium and phosphorus. According to Dr. Linia Patel, a researcher from Milan and a representative of the British Dietetic Association, it serves an important role in countering systemic inflammation linked to various chronic diseases. Unfortunately, not many foods are good sources of vitamin D; mainly, it comes from sun exposure. A deficiency can significantly impact bone and muscle health, and estimates suggest that around one in six adults in the UK may have low levels of this vitamin. Some studies have indicated a correlation between supplement intake and decreased risk of deficiency.
Should I be taking it?
Yes, it’s advisable for everyone to take a supplement of 10mcg daily from the end of September through April. Certain groups—like children aged 1 to 4, infants not consuming fortified formula, and those at risk due to age or lifestyle—should consider year-round supplementation.
Creatine
Often used by gym enthusiasts seeking better muscle definition and recovery, creatine naturally occurs in the body and is found in red meat and seafood. It’s known for its role in cellular energy production. Numerous studies confirm its effectiveness in enhancing exercise performance and aiding in recovery, while others suggest it might have cognitive benefits, though some claims were dismissed by the European Food Safety Authority last year. Still, recent findings hint there might be more to uncover on this front.
Should I be taking it?
Individuals who exercise regularly and those over 65 may find it beneficial.
Lion’s Mane
This mushroom, known for growing on old trees, contains compounds believed to support brain health. Some initial studies suggest it might help with brain cell growth, but much of the research is limited and based on animal subjects. The Advertising Standards Agency has questioned any overreaching claims regarding its cognitive benefits.
Should I be taking it?
It appears safe to consume, though more thorough studies are necessary.
Magnesium
This mineral is vital for muscle and nerve function and is sometimes marketed as a sleep aid. Research indicates that low magnesium levels could disrupt nerve signaling and sleep-regulating hormones. Most people can get sufficient magnesium from dietary sources like nuts, leafy greens, and fish.
Should I be taking it?
It’s rare to find someone overdosing on magnesium due to its natural laxative effects, but trying a dosage of around 300mg for a few weeks could be helpful.
Probiotics
These beneficial bacteria are essential for maintaining a balanced gut microbiome, potentially boosting health and immunity. There’s evidence that some probiotics work well, but it’s crucial to select the right strains based on your specific health needs.
Should I be taking them?
It might be worth consulting a healthcare provider for advice on effective probiotics tailored to your requirements.
Vitamin C
This vitamin plays a key role in supporting the immune system and aids in collagen production for skin health. Being water-soluble, our bodies require a consistent supply. Current NHS guidelines recommend a daily intake of 40mg for those 15 and older.
Should I be taking it?
If you don’t consume much fruit and vegetables or if you’re a smoker, supplementation could be beneficial.
Ashwagandha
This herb, used in traditional Indian medicine, is promoted for relieving stress by lowering cortisol levels. While some studies have shown it might reduce anxiety significantly, many claims about its other benefits are anecdotal or based on small trials.
Should I be taking it?
It’s not recommended, as there could be health risks involved, especially for children, pregnant women, and those with liver conditions.
Collagen
Often touted for its skin, hair, and joint benefits, collagen is a key structural protein in the body. While some studies show that it might help with tendon and muscle health, a recent review indicated no solid evidence supporting collagen for skin aging.
Should I be taking it?
Unless you’re an athlete or frequently injured, it’s probably unnecessary.
Turmeric
The active ingredient, curcumin, is noted for its anti-inflammatory properties and is often taken for various ailments, though evidence is mixed. Some research suggests turmeric could effectively reduce stomach acid, while others question its benefits for joint health.
Should I be taking it?
Consider it if you exercise regularly or have issues with stomach acid—just ensure it includes black pepper for better absorption.
Zinc
This mineral is crucial for immune function and is often recommended during cold season. However, recent findings suggest it might not prevent colds but may shorten their duration.
Should I be taking it?
Possibly, especially for those over 60 or experiencing cold symptoms.
Glucosamine
This compound is frequently taken to alleviate joint pain, but studies show little effect on knee pain relief.
Should I be taking it?
It would be best to skip it as it doesn’t seem to offer benefits.
Vitamin B12
Essential for blood and nerve function, B12 is mainly found in animal products. Low levels can lead to fatigue and cognitive issues, particularly in older adults.
Should I be taking it?
Yes, especially for vegans or vegetarians and could be useful for seniors exhibiting low levels.
Iron
Necessary for energy levels, iron supports various bodily functions and is generally obtainable through a balanced diet. However, deficiency can manifest, particularly in women.
Should I be taking it?
Possibly, especially if you’re pregnant or have been diagnosed with low levels. Be cautious, though, as excess iron can be toxic.
Psyllium
This soluble fiber derived from Plantago ovata is often used for weight management and digestive health. Studies suggest it helps lower cholesterol and improve gut health.
Should I be taking it?
Only if you’re experiencing constipation; some specific brands are available for short-term use.
Omega-3
A well-known supplement for heart health, omega-3 fatty acids are primarily sourced from fish and nuts. Findings suggest high-dose fish oil may offer more benefits compared to fish alone, but ongoing research shows mixed results regarding its effect on heart conditions.
Should I be taking it?
Consideration of a capsule might be worthwhile if you’re not eating fish, yet it’s best to consult a doctor first.
Multivitamins
These can be beneficial for those struggling to meet their nutritional needs through diet alone. While some studies have found little health benefit, they may provide cognitive enhancements for older adults.
Should I be taking it?
It could be worth a try, especially for those with poor diets or individuals over 60, as absorption of vitamins tends to decline with age.
