Daily Core Supplements: Her Foundation

These are the supplements Rhonda Patrick takes every day to maintain her health, focus, and energy. Each one supports a specific system in the body, and together they form the foundation of her routine.

1. Multivitamin

Rhonda calls her daily multivitamin her “nutritional insurance.” She takes Pure Encapsulations ONE because it includes active forms of B vitamins, methylated folate, and chelated minerals that are easier for the body to use.

Research shows that taking a high-quality multivitamin can help improve nutrient levels and reduce deficiencies (1). It’s a simple way to fill the small nutritional gaps that most adults have.

Still, Rhonda emphasizes that supplements should support a healthy diet, not replace it. Her advice is to eat real food first and use a multivitamin as a safety net when life gets hectic.

2. Omega-3 (EPA/DHA)

Omega-3s are at the heart of Rhonda’s supplement routine. She takes around 2,000 to 2,400 mg of EPA and DHA daily from a high-quality fish oil, often Metagenics EPA DHA 2400.

Her goal is to keep her omega-3 index above 8 percent, a level linked with stronger heart and brain health.

People with higher omega-3 levels tend to have lower inflammation, better cognitive function, and a reduced risk of cardiovascular disease (2). Regular omega-3 use is also associated with longer life expectancy compared to low intake.

Rhonda often calls this one of the best evidence-backed supplements for longevity and cellular support.

3. Vitamin D3 + K2

Rhonda takes about 4,000 to 6,000 IU of vitamin D3 each day, along with 100 mcg of vitamin K2 in the MK-7 form. She aims to keep her vitamin D levels between 40 and 60 ng/ml, which is considered ideal for most adults.

Vitamin D3 supports strong bones, a healthy immune system, and a balanced mood (3). Vitamin K2 works alongside D3, directing calcium to the bones instead of the arteries.

4. Magnesium

Magnesium is one supplement Rhonda rarely skips. She takes around 120 to 130 mg of magnesium glycinate during the day and adds a magnesium and L-theanine blend at night to help her unwind.

Magnesium supports muscle and nerve function, steady energy levels, and deeper sleep (4). Many people don’t get enough of it, which can lead to fatigue or poor sleep.

5. Creatine

Creatine isn’t just for athletes, in Rhonda’s view. She takes 5 grams of creatine monohydrate daily for both physical strength and mental clarity.

It helps the body produce more ATP, the main source of energy for muscles and the brain. Research shows that creatine can improve memory and support recovery after workouts (5).

Performance and Longevity Support

6. Alpha Lipoic Acid (ALA)

Some research suggests that ALA may improve insulin sensitivity and reduce nerve-related discomfort (6). It also supports mitochondrial function.

7. PQQ (Pyrroloquinoline Quinone)

Rhonda takes around 20 mg daily to support mitochondrial energy and cognitive function. Evidence so far comes largely from animal research (7).

8. CoQ10 (Coenzyme Q10)

CoQ10 helps cells produce ATP. Research shows it can improve exercise performance and reduce fatigue (8).

9. Benfotiamine

Benfotiamine helps protect the body from excess oxidative stress and blood sugar fluctuations (9).

Detox and Antioxidant Stack

10. Sulforaphane (Avmacol)

Some studies suggest that sulforaphane boosts cellular resilience and supports brain health by reducing inflammation (10).

11. Cocoa Extract

Cocoa flavanols may enhance cognitive performance by increasing oxygen delivery to the brain (11).

Evening Stack: Relaxation and Sleep

12. Magnesium Blend with L-theanine

L-theanine is an amino acid known to reduce stress and quiet mental chatter (12).

13. Melatonin (10 mg)

Studies suggest it acts as an antioxidant, supporting brain and cellular health (13).

Situational or Occasional Supplements

14. Glutamine

Research suggests that glutamine may help reduce muscle soreness and support immune function (14).

16. Collagen

Studies suggest that hydrolyzed collagen can help improve skin hydration and reduce joint pain (16).

Should You Follow Rhonda Patrick’s Supplement Routine?
