Whether you’re looking to boost your immune system, improve energy levels, or support your mental health, the following supplements are among the most popular and highly recommended in 2025.
Here’s a roundup of the top supplements to take in the UK right now based on their proven health benefits and consumer demand.
1. Vitamin D3: The Sunshine Vitamin
Why it’s popular:
In the UK, where sunlight can be scarce during the colder months, many people suffer from Vitamin D deficiency. Vitamin D plays a vital role in supporting immune function, mood regulation, bone health, and muscle function. It’s especially important for those living in northern latitudes where sunlight exposure is limited.
Key Benefits:
- Supports immune health and reduces the risk of infections
- Promotes healthy bones by aiding calcium absorption
- May reduce symptoms of depression, especially during the winter months
- Supports healthy muscle function and strength
Recommended Dosage: 1000–4000 IU daily (depending on age, diet, and health status).
2. Omega-3 Fish Oil: Heart and Brain Health
Why it’s popular:
Omega-3 fatty acids, especially EPA and DHA, are essential for maintaining heart, brain, and eye health. The typical Western diet is often lacking in omega-3s, leading many people to supplement with fish oil or algae-based omega-3 supplements.
Key Benefits:
- Supports cardiovascular health by lowering triglycerides and blood pressure
- Improves brain function, memory, and mood regulation
- Promotes healthy skin and reduces inflammation
- Enhances joint health and may help reduce symptoms of arthritis
Recommended Dosage: 1000–2000 mg of EPA and DHA combined daily.
3. Probiotics: Gut Health and Immunity
Why it’s popular:
Probiotics have become a staple in many households, thanks to their ability to support gut health and the immune system. A healthy gut microbiome is crucial for digestion, immune function, and even mental well-being. As interest in gut health grows, probiotics have emerged as a go-to supplement for maintaining a balanced microbiome.
Key Benefits:
- Supports digestive health and may reduce bloating, gas, and constipation
- Enhances the immune system by promoting healthy gut flora
- May improve mood and reduce symptoms of anxiety and depression
- Improves skin health by balancing the gut-skin connection
Recommended Dosage: 10–20 billion CFU (colony-forming units) per day, depending on the strain and health goals.
4. Magnesium: Relaxation and Recovery
Why it’s popular:
Magnesium is a vital mineral that plays a role in over 300 biochemical reactions in the body, from muscle function to nerve transmission. Given the fast-paced, stressful lifestyles many people lead, magnesium supplementation is becoming increasingly popular, especially for promoting relaxation and better sleep.
Key Benefits:
- Reduces stress and anxiety by regulating the nervous system
- Supports better sleep quality and combats insomnia
- Aids muscle relaxation and recovery after exercise
- Promotes bone health by working with calcium and vitamin D
Recommended Dosage: 200–400 mg daily, preferably in the evening to aid relaxation.
5. Turmeric (Curcumin): Anti-Inflammatory Powerhouse
Why it’s popular:
Turmeric, particularly its active compound curcumin, is gaining popularity in the UK due to its powerful anti-inflammatory and antioxidant properties. It’s widely used to alleviate joint pain, reduce inflammation, and promote overall health.
Key Benefits:
- Reduces inflammation and alleviates joint pain (ideal for those with arthritis)

- Acts as a natural antioxidant, protecting cells from oxidative stress

6. Ashwagandha: Stress Relief and Adaptogen
Why it’s popular:
Ashwagandha, an adaptogenic herb, has risen in popularity in the UK for its ability to help the body adapt to stress and promote overall vitality. Known for its calming effects, it’s commonly used to support mental well-being and physical recovery.

7. Collagen: Skin, Hair, and Joint Support
Why it’s popular:
Collagen supplements have become a must-have for those looking to improve skin elasticity, promote hair growth, and support joint health. Collagen production naturally decreases with age, which is why many people are turning to collagen peptides to replenish this important protein.
Key Benefits:
- Improves skin elasticity and reduces the appearance of wrinkles
- Strengthens hair and nails, promoting growth and preventing breakage
- Supports joint health by improving cartilage and reducing pain
- Promotes bone health by maintaining bone density
Recommended Dosage: 2.5–15 grams of collagen peptides daily.
8. Vitamin B12: Energy and Nerve Health
Why it’s popular:
Vitamin B12 is crucial for energy production, brain function, and nerve health. Vegans, vegetarians, and older adults are particularly prone to vitamin B12 deficiency, making supplementation essential for many.
Key Benefits:
- Boosts energy levels and combats fatigue
- Supports cognitive function and mental clarity
- Helps maintain healthy nerve cells and prevents nerve damage
- Improves mood and may help alleviate symptoms of depression
Recommended Dosage: 1000 mcg (for those with a deficiency) or 250–500 mcg daily for maintenance.
9. Vitamin C: Immune Support and Antioxidant Protection
Why it’s popular:
Vitamin C is an essential nutrient known for its immune-boosting properties and its ability to protect cells from oxidative damage. It’s commonly used during cold and flu season, but it offers year-round benefits for skin, heart health, and more.

Key Benefits:
- Enhances immune function and shortens the duration of colds
- Supports wound healing and skin health (helps with acne and eczema)
