Josie Porter, a clinical dietitian, notes that the supplement industry has evolved from treatments for deficiencies to popular wellness products. While supplement advertisements can be persuasive, evidence supporting their health claims is often limited. The industry lacks FDA regulation, making it unclear whether products contain what they claim.
Porter emphasizes the importance of scientific backing in supplement usage and mentions three specific supplements she takes:
### Vitamin D
– Recommended in the UK during the fall and winter for limited sunlight exposure.
– Supports the immune system and calcium absorption, vital for bone health.
### Omega-3
– Taken when oily fish isn’t consumed for a time.
– Linked to better heart health, joint health, lower inflammation, and reduced blood pressure.
– Whole food sources like fish are preferred over supplements.
### Collagen
– Used to aid tendon recovery and improve skin hydration and elasticity.
– Available in various forms, with marine or bovine sources being more effective than vegan alternatives, which may contain ingredients that promote collagen production instead.
Porter’s approach highlights the importance of sensible supplement choices grounded in research.
