What They Agree On
Both Simon Hill and Tim Spector include these 5 products in their protocols — a signal of strong evidence and broad expert consensus.
Omega-3 Fish Oil (High EPA)
High-potency omega-3 fish oil supplement with elevated EPA content. Supports cardiovascular health, reduces systemic inflammation, and promotes healthy brain function and mood regulation.
Omega-3 Fish Oil (High EPA)
supplements
Probiotics (Multi-Strain)
Multi-strain probiotic supplement containing diverse beneficial bacteria to support gut microbiome health. A balanced gut microbiome is linked to improved digestion, immune function, and mental well-being. Look for formulas with clinically studied strains and high CFU counts.
Probiotics (Multi-Strain)
supplements
Mixed Berries (Blueberries, Blackberries)
Nutrient-dense berries packed with anthocyanins and polyphenols that support brain health and reduce oxidative stress. Blueberries in particular have been linked to improved memory and cognitive function in clinical studies. A low-glycemic fruit option ideal for daily consumption in longevity-focused diets.
Mixed Berries (Blueberries, Blackberries)
foods
Broccoli
Broccoli is a nutrient-dense cruciferous vegetable rich in sulforaphane, a powerful compound that activates cellular detoxification pathways. Studies show broccoli consumption supports DNA repair mechanisms and may help reduce inflammation. Longevity researchers recommend broccoli for its ability to activate Nrf2 pathways that protect against oxidative stress and cellular damage.

foods
Fermented Foods (Kimchi, Sauerkraut, Kefir)
Naturally fermented foods rich in live beneficial bacteria to support gut microbiome diversity. Regular consumption of kimchi, sauerkraut, and kefir has been shown to reduce markers of systemic inflammation. A Stanford study found fermented foods increased microbial diversity more effectively than a high-fiber diet.

Where They Differ
These products are unique to one protocol — reflecting each expert's distinct philosophy, research focus, and priorities.
Only in Simon Hill's Protocol
Vitamin D3 (5000 IU)
High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.
Vitamin C
High-quality vitamin C supplement supporting immune function, collagen synthesis, and antioxidant defense. Essential for tissue repair and iron absorption. Liposomal forms offer enhanced bioavailability compared to standard ascorbic acid.
Only in Tim Spector's Protocol
Extra Virgin Olive Oil
Cold-pressed extra virgin olive oil, a cornerstone of Mediterranean and longevity diets. Rich in polyphenols and oleic acid.
Dark Chocolate (85%+ Cacao)
High-cacao dark chocolate rich in flavanols and antioxidants. Studies link regular consumption to improved cardiovascular health, lower blood pressure, and enhanced cognitive function.
