The Only Three Supplements I Take

The speaker unpacks the heart-health data: the VITAL trial (25,000+ adults, 5 years) showed omega-3 lowered heart attack risk 28% vs placebo. A Mayo Clinic meta-analysis of 40 studies found a 13% reduction in heart attacks and a 35% reduction in fatal heart attacks. However, a 2024 cohort of 400,000 people found 31.4% took omega-3 and had a 13% higher risk of atrial fibrillation; the STRENGTH trial using 4 g/day showed a 69% increased risk. The sweet spot, he argues, is around 1 g/day — enough for cardiovascular benefit, below the AFib danger zone. For the brain, he explains that DHA is the structural building block for neuronal membranes, while EPA quenches neuroinflammation. Yet RCTs were inconsistent until researchers re-analyzed data through the lens of B vitamin status. In the VITACOG re-analysis, B vitamins reduced brain shrinkage by 40% in people with high omega-3, but gave zero benefit in those with low omega-3. Reciprocally, omega-3 improved cognition only in participants with low homocysteine (healthy B vitamin levels). The proposed mechanism is that B vitamins are needed to make phosphatidylcholine, which shuttles DHA/EPA into the brain. Therefore, he concludes that the full potential of omega-3 is unlocked only when B vitamin levels are adequate. He personally takes ~1 g omega-3 and ensures he meets his B vitamin needs through his custom multivitamin.

He cites a three-year Canadian trial that directly compared 400 IU, 4,000 IU, and 10,000 IU of vitamin D daily. The 400 IU group maintained bone density, whereas the 4,000 IU group lost 2.4% and the 10,000 IU group lost 3.5% in wrist bone mineral density. In a separate three-month study of vitamin-D-deficient women, 2,800 IU reduced hand grip strength by 9% and leg strength by 13%. Emerging evidence also signals increased falls in older adults on high doses. Thus, while vitamin D is essential, more is not better and can be harmful. The speaker settled on 1,000 IU as a moderate dose that likely meets needs without crossing into harm, and adds 90 mcg of vitamin K2 as MK-7 to support calcium deposition in bone and possibly reduce arterial calcification. He acknowledges the topic is nuanced and directs viewers to a separate detailed video.

The speaker explains that the pineal gland produces only 10-80 micrograms of melatonin each night. Because oral supplements have about 15% absorption, a 300 mcg dose delivers roughly 45 micrograms—matching the natural range. In contrast, 10 mg pills flood the system with many times that amount, and we have no long-term safety data. Meta-analyses of 14 studies show melatonin reduces sleep onset latency, and additional reviews indicate improved sleep quality. The timing is crucial: taking it 2 hours before bed helps shift the circadian rhythm earlier, not just act as a sedative. He formulated his sleep supplement around this 300 mcg dose to stay within physiological boundaries, viewing it as a conservative, evidence-based approach to sleep support.

The speaker differentiates between the forms of magnesium he uses: magnesium taurate in the morning (in Microvitamin) and magnesium glycinate at night. He cites a recent meta-analysis summarizing RCTs on magnesium for sleep; while results are not uniform, a majority of studies reported improvements. He selected glycinate specifically because glycine has its own sleep and cognition benefits. He combines magnesium glycinate with melatonin and extra glycine in his custom sleep supplement.

He recounts the 2006 study: participants with sleep complaints took glycine or placebo before bed and completed questionnaires the next morning. Glycine significantly improved subjective feelings of liveliness and clear-headedness and reduced fatigue. Two follow-up studies reinforced these findings. He included glycine in his sleep supplement to complement melatonin and magnesium, targeting both sleep onset and next-day cognitive recovery.

The speaker explains that collagen gives skin firmness and elasticity, and breaking it down into peptides enhances absorption. He includes collagen peptides in his Microvitamin Plus powder. He cites a 2023 meta-analysis confirming efficacy, noting the studies consistently show improvements in skin hydration and elasticity.

He states that creatine is one of the most well-studied supplements with a strong majority of RCTs showing significant improvements in muscle strength and recovery. He incorporated it into his Microvitamin Plus powder to consolidate his daily intake.

He summarizes a recent meta-analysis that pooled evidence on taurine’s metabolic effects, showing consistent improvements across multiple cardiometabolic parameters. Taurine was added to his Plus powder for these broad benefits.

He notes psyllium husk is a well-studied soluble fiber with benefits across constipation, cholesterol reduction, weight management, and inflammation. He included it in his Plus powder to cover fiber intake conveniently.

The speaker recounts the VITACOG trial, where B vitamins alone reduced brain shrinkage by 29.6% overall. The 2015 re-analysis found that this benefit was entirely driven by subjects with high baseline omega-3 levels: in that subgroup, brain shrinkage was slashed by 40%, while those with low omega-3 got zero benefit. Separately, a 2006 omega-3 trial had shown no cognitive improvement; but in 2019, researchers re-examined the data and discovered that among participants with low homocysteine (indicating healthy B vitamin levels), omega-3 did improve brain performance by 7.1% and cut dementia symptoms by 22.3%. For subjects with poor B vitamin status, omega-3 still did nothing. The speaker frames this as a 'puzzle solved' — B vitamins are critical for producing phosphatidylcholine, which carries omega-3 into the brain. He cautions that the mechanism needs more study and concedes that the effect size for healthy non-fish-eaters is small, but the evidence is strong enough that he now ensures he gets adequate B vitamins alongside his omega-3. This insight directly informs his personal supplement protocol and the design of his multivitamin.

The speaker highlights a three-year Canadian RCT: one group received 400 IU, another 4,000 IU, and a third 10,000 IU daily. The 4,000 IU group lost 2.4% wrist bone mineral density, the 10,000 IU group lost 3.5%, while the 400 IU group remained stable. In a separate intervention study, women with low vitamin D received 2,800 IU for three months; their hand grip strength fell by 9% and leg strength by 13%. He also mentions emerging evidence that high-dose vitamin D may increase fall risk in older adults. Contrasting these harms, he identifies 1,000 IU as a safe, effective dose that avoids the risks seen with higher intakes. This stance runs counter to the popular 'more is better' narrative and underpins his decision to include only 1,000 IU in his multivitamin along with 90 mcg of K2 MK-7 to potentially aid calcium distribution.

He cites the US Preventive Services Task Force (USPSTF) 2022 systematic review with moderate certainty that vitamin E supplementation provides no net benefit for preventing cardiovascular disease or cancer. He adds that the SELECT trial linked vitamin E to an increased risk of prostate cancer. Moreover, antioxidant supplements like vitamin E can interfere with the beneficial adaptations to exercise. Because vitamin E deficiency is extremely rare—the vitamin is abundant in a wide variety of foods—there is no need to supplement and doing so may cause harm. This conclusion is a major reason he excluded vitamin E from his own multivitamin, unlike many commercial formulas that often contain high doses.
