The Science Behind Natural Supplements
What Makes a Supplement “Natural”?
Natural supplements are derived from whole food sources, plants, minerals, or other naturally occurring substances, rather than being synthetically manufactured. However, “natural” doesn’t automatically mean “safe” or “effective.” Although it’s a slow process, careful, objective medical studies provide the guidance that counts. In most cases, scientific investigations of supplements start with simple observational studies, in which researchers compare the health status of folks who take a particular supplement with the health of people who don’t take the supplement.
The Evidence Standard
Most supplements haven’t been proven to be effective, and some may not benefit you at all. Still, there are exceptions. In fact, some supplements are comparable to pharmaceutical drugs. This guide focuses exclusively on natural supplements with robust scientific backing.
Top 12 Best Natural Supplements
1. Omega-3 Fatty Acids ⭐⭐⭐⭐⭐
Primary Benefits: Heart health, brain function, inflammation reduction
Omega-3 fatty acids, particularly EPA and DHA found in fish oil, rank among the most researched natural supplements. For years, doctors have known that people who eat fish regularly enjoy some protection against heart disease and stroke. For people with cardiovascular disease who don’t eat fish regularly, taking a fish oil supplement is reasonable.
Dosage: 1,000-2,000mg combined EPA/DHA daily Best Form: Molecularly distilled fish oil or algae-based for vegans Quality Tip: Look for third-party testing for purity and freshness
2. Vitamin D3 ⭐⭐⭐⭐⭐
Primary Benefits: Bone health, immune function, mood support
Vitamin D is fat-soluble, so you may require a higher dosage, says Michael F. Holick, MD, a vitamin D researcher and professor of endocrinology, diabetes, nutrition, and weight management at Boston University School of Medicine.
Dosage: 1,000-4,000 IU daily (based on blood levels) Best Form of Vitamin D3: Vitamin D3 (cholecalciferol) over D2 Quality Tip: Consider pairing with Vitamin K2 for optimal absorption
3. Magnesium ⭐⭐⭐⭐⭐
Primary Benefits: Sleep quality, muscle function, stress reduction
Badgett most often suggests magnesium supplements for people who have constipation, insomnia, or chronic migraines. But others might benefit because nearly half of Americans don’t get enough from food.
Dosage: 200-400mg daily Best Forms: Magnesium glycinate, citrate, or threonate Quality Tip: Avoid magnesium oxide due to poor absorption
4. Turmeric/Curcumin ⭐⭐⭐⭐
Primary Benefits: Anti-inflammatory, antioxidant properties, joint health
Nevertheless, curcumin is poorly absorbed, so it’s best to get a supplement that also contains piperine/bioperine, which has been shown to enhance its absorption by 2,000%.
Dosage: 500-1,000mg curcumin daily Best Form: Curcumin with piperine/bioperine for enhanced absorption Quality Tip: Look for standardized curcumin extracts (95% curcuminoids)
5. Probiotics ⭐⭐⭐⭐
Primary Benefits: Digestive health, immune support, mental well-being
Gut health has solidified its position as a cornerstone for multifunctional products, with a growing body of research linking digestive wellness to overall health.
Dosage: 10-50 billion CFUs daily Best Strains: Lactobacillus and Bifidobacterium varieties Quality Tip: Choose refrigerated or shelf-stable with proven viability
6. Ashwagandha ⭐⭐⭐⭐
Primary Benefits: Stress reduction, cortisol balance, energy support
Emerging ingredients that support high-performance needs include creatine, while ashwagandha is showing up in supplements positioned for gentle, plant-based energy.
Dosage: 300-600mg daily Best Form: Standardized root extract (withanolides 1.5-12%) Quality Tip: Take consistently for 2-8 weeks for optimal benefits
7. Berberine ⭐⭐⭐⭐⭐
Primary Benefits: Blood sugar control, cholesterol management, weight support
Berberine is a bioactive substance extracted from certain plants. It isn’t well known but may be one of the most powerful supplements on Earth. Studies show that taking berberine can lower blood sugar levels to a similar extent as the popular diabetes drug metformin.
Dosage: 500mg, 2-3 times daily before meals Best Berberine Form: Berberine HCl Quality Tip: Take with meals to improve absorption and reduce GI upset
8. Collagen Peptides ⭐⭐⭐⭐
Primary Benefits: Skin health, joint support, hair and nail strength
In a 2020 randomized double-blind pilot clinical trial comparing the effects of 36 g hydrolyzed bovine collagen to 35 g soy protein on wound healing in male burn patients, wound healing rates were significantly higher following supplementation with hydrolyzed collagen.
Dosage: 10-20g daily Best Collagen Form: Hydrolyzed collagen peptides (Types I & III) Quality Tip: Grass-fed, pasture-raised sources preferred
9. Coenzyme Q10 (CoQ10) ⭐⭐⭐
Primary Benefits: Heart health, cellular energy production, antioxidant support
This is an antioxidant your body makes, and you can get more of it in pill form. People try to use CoQ10 to fight migraines, protect the heart, and improve symptoms of Parkinson’s disease.
Dosage: 100-200mg daily Best Form: Ubiquinol (active form) over ubiquinone Quality Tip: Take with fats for better absorption
10. Melatonin ⭐⭐⭐⭐
Primary Benefits: Sleep quality, circadian rhythm regulation, antioxidant properties
Taking melatonin can help people fall asleep about 7 minutes faster, on average, and studies show that it’s useful for people with jet lag or a sleep disorder called delayed sleep phase syndrome.
Dosage: 0.5-3mg, 1-2 hours before bedtime Best Form: Immediate-release for sleep onset Quality Tip: Start with the lowest effective dose
11. Creatine Monohydrate ⭐⭐⭐⭐⭐
Primary Benefits: Muscle performance, cognitive function, recovery
Creatine can also be used to increase high-intensity exercise capacity and lean body mass (rather than fat mass) during training. Initial safety concerns regarding creatine have been disproven.
Dosage: 3-5g daily Best Form: Creatine monohydrate (most researched) Quality Tip: No loading phase necessary; consistent daily use is key
12. Zinc ⭐⭐⭐⭐
Primary Benefits: Immune function, wound healing, hormone support
Zinc is essential for immune function and cellular metabolism. Research shows it may help reduce the duration of common cold symptoms and support healthy testosterone levels.
Dosage: 8-15mg daily Best Form: Zinc picolinate or bisglycinate Quality Tip: Take on empty stomach or with minimal food for best absorption
