Are you overwhelmed by the supplement aisle? You’re not alone. With so much conflicting advice out there, it can be overwhelming to know which supplements truly help — and which are just hype. The truth is — you don’t need dozens of bottles to build a strong health foundation. In my practice, I consistently recommend a simple set of six supplements that support immunity, energy, brain health, and longevity — all based on solid clinical research.
To help you find Better Health Through Smarter Supplements, I have compiled information on supplements that I feel are helpful and what supplement benefits each system, including supporting research for each.
Why Daily Supplements?
Even with the best intentions, most modern diets fall short in delivering all the nutrients our bodies need for optimal function. Add in stress, busy lifestyles, and environmental factors — and gaps in nutrition are almost inevitable. To help you find your own Better Health Through Better Supplements, I will discuss:
- Benefits for each supplement
- How to take for maximum effectiveness
- What the research says
- Conditions that each supplement benefit

For your Foundation Health, I recommend a simple core set of supplements to support general health, energy, immunity, and longevity. Here’s a look at the six I take myself and suggest to many of my patients:
Vitamin D3: The Sunshine Vitamin
Why: Vital for strong bones, a resilient immune system, and even mood balance.
Dosage: 1,000–2,000 IU daily with a meal that includes fat.
Key research: Vitamin D deficiency is widespread and linked to osteoporosis, infections, and chronic diseases (PMID: 17634462).
Vitamin K2: Calcium’s Guide
Why: Helps Vitamin D3 direct calcium to your bones — not your arteries. Essential for cardiovascular health.
Dosage: 90–120 mcg daily with a fat-containing meal.
Key research: Vitamin K2 supports both heart and skeletal health (PMID: 22875275).
NAC (N-Acetyl Cysteine): Master Antioxidant Support
Why: Boosts glutathione, the body’s main antioxidant, and supports liver detox. Also helpful for respiratory health.
Dosage: 600–1,200 mg daily on an empty stomach or light snack.
Key research: NAC helps reduce oxidative stress and supports detoxification pathways (PMID: 11470772).
Zinc: Immunity and Repair
Why: Critical for immune function, wound healing, and skin health. Many are deficient due to stress, aging, or poor absorption.
Dosage: 15–30 mg daily with food.
Key research: Zinc plays a key role in immune resilience and cellular repair (PMID: 18385818).
Creatine Monohydrate: More Than Muscle
Why: Creatine isn’t just for athletes — it supports muscle strength, brain function, and healthy aging. Emerging research suggests benefits for cognitive performance and energy metabolism.
Dosage: 3–5 grams daily, mixed in water or a smoothie.
Key research: Proven safety and efficacy for muscle, brain, and overall health (PMID: 28615996).
AG1 (Athletic Greens or Similar Whole Food Multinutrient Blend
Why: A simple way to cover common gaps in vitamins, minerals, adaptogens, and probiotics — especially helpful for busy days or frequent travelers.
Dosage: 1 scoop daily, mixed in water.
Key research: Comprehensive multinutrient blends can help fill dietary gaps and support overall wellness (Review: J Orthomol Med. 2014). Click here to order AG1
Deep Dive into Vitamin D3
Vitamin D deficiency is a public health problem affecting nearly 50% of the global population. As one of the most studied nutrients in recent decades, data shows the many chronic diseases associated with Vitamin D deficiency.
Vitamin D contributes to overall well-being, promoting a strong skeletal system, facilitating muscle movement, supporting the immune system, and optimizing cellular functions. This fat-soluble vitamin is found naturally in a small selection of foods and is often added artificially to foods. Vitamin D is widely taken as a supplement. Our bodies also produce vitamin D through skin exposure to sunlight, the main source of vitamin D for humans.
It is well-established that as an essential nutrient, vitamin D plays an integral role in promoting overall health and well-being; however, individual variations in vitamin D metabolism and requirements is more complex. Mainly synthesized in the skin when stimulated by ultraviolet-B (UV-B) exposure, understanding this unique metabolism is crucial to addressing the widespread deficiency of this vitamin.
How the Body Converts Vitamin D
When derived from a food source, Vitamins D enters the bloodstream through the small intestines by passive diffusion. Because D is a fat-soluble vitamin, absorption is enhanced by a small amount of fat in the intestines.
7-dehydrocholesterol, however, plays an even larger role in the production of D3 in our body. 7-dehydrocholesterol is a type of lipid that acts as a precursor to cholesterol. It is also a direct precursor to Vitamin D3 when exposed to ultraviolet radiation from the sun. This process is called photolysis. When the UVB radiation from the sun enters the skin, 7-dehydrocholesterol is transformed to pre-vitamin D3. From here, it must be converted to vitamin D3.
Both vitamin D3 derived from food and that produced through skin synthesizes are actually inactive forms of the vitamin. Vitamin D must be converted to its active form to have its many effects in the human body. The process of activation includes two reactions of hydroxylation.
Vitamin D3 is transported to the liver. Here it is converted to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. Calcidiol is the main form of vitamin D circulating in the bloodstream and is used to evaluate the body’s vitamin D status. The half-life in the blood is approximately two to three weeks.
