The Editorial Staff would like to discuss a resin that has been chewed on the Greek island of Chios since approximately 500 BC, which is roughly 2,470 years before anyone thought to put collagen in a gummy bear. Mastic gum is the crystallized sap of Pistacia lentiscus var. Chia, a tree that grows exclusively in southern Chios and has, to date, resisted every attempt at cultivation elsewhere. The tree simply refuses to produce resin outside its preferred terroir, a fact the Editorial Staff finds admirable. The clinical literature is not thin. Dabos et al. (2010, PMID 19961914) enrolled 148 patients with functional dyspepsia and administered 350mg of mastic three times daily for three weeks. The improvement was statistically significant. Kaliora et al. (2007, PMID 17278198) gave 2.2g daily to Crohn’s disease patients for four weeks and observed decreased disease activity indices, reduced IL-6, and lowered C-reactive protein. A subsequent study from the same group confirmed TNF-α reduction (PMID 18023095). Papada et al. (2019, PMID 30450689) expanded the scope: 60 IBD patients received 2.8g daily for three months and showed improved quality-of-life scores and decreased fecal lysozyme. On the cardiovascular front, Triantafyllou et al. (2007, PMID 17150319) administered 5g daily to 133 patients for 18 months — total cholesterol, LDL, and apolipoprotein levels all decreased. Kartalis et al. (2016, PMID 26311707) confirmed the finding in 156 subjects at a lower dose of 1g daily. Then there is Helicobacter pylori. Kottakis et al. (2009, PMID 19212203) demonstrated that mastic’s arabinogalactan proteins inhibit neutrophil activation in H. pylori-infected patients. Dabos et al. (2010, PMID 19879118) achieved eradication in 5 of 13 subjects at 1.05g daily — modest, but notable given that the comparator was nothing. For the jaw enthusiasts: mastic in its raw tear form provides sustained resistance that silicone jaw exercisers cannot replicate, because it is, in point of fact, actual tree resin and not a novelty product purchased at 3 a.m. The Editorial Staff has been chewing a piece while writing this article. It tasted of pine and vindication.

The Editorial Staff must begin with a description. Shilajit is a dark, viscous, tar-like substance that seeps from rock formations in the Himalayas, Altai, Caucasus, and Andes at altitudes above 3,000 meters. It is formed over centuries from the slow decomposition of plant matter compressed between layers of rock. It smells approximately how you would expect a substance formed over centuries from decomposing plant matter compressed between layers of rock to smell. You will put it in your mouth on purpose. The reason is fulvic acid. Shilajit is 60–80% humic substances by weight, with fulvic acid as the dominant bioactive compound (Carrasco-Gallardo et al., Journal of Alzheimer’s Disease, 2012, PMC 3296184). Fulvic acid has a molecular weight of approximately 2 kDa, which allows it to cross intestinal membranes with an efficiency that most supplement manufacturers would describe as ‘enviable.’ Cornejo et al. (2011, PMID 21785188) demonstrated that fulvic acid blocks tau protein self-aggregation — the pathological process underlying Alzheimer’s disease — and promotes disassembly of existing tau fibers. The antioxidant capacity is not trivial: Andean shilajit registers ORAC values of 50–500 Trolox units per gram, substantially exceeding noni and blueberries. The documented pharmacological profile includes antiulcerogenic properties (Ghosal et al., 1988), cognitive enhancement (Jaiswal & Bhattacharya, 1992), antidiabetic effects (Bhattacharya, 1995), anti-inflammatory activity (Acharya et al., 1988), and immunomodulatory function (Ghosal, 1990). The Editorial Staff must now address the single most important issue in the shilajit market: purity. Unpurified shilajit from internet vendors has tested positive for lead, mercury, and arsenic (Saper et al., 2008, PMID 18728265). The distinction between purified and unpurified shilajit is the distinction between an ancient Ayurvedic remedy and heavy metal poisoning. To acquit yourself of the real stuff, demand a Certificate of Analysis (COA) from an independent third-party lab — not an in-house test. Look for three things: heavy metals (lead, mercury, cadmium, arsenic should read ‘ND’ or near-zero), microbial safety (cleared for E. coli, Salmonella, and mold), and the testing lab’s name (Eurofins, NSF, or equivalent). Lotus Blooming Herbs publishes their COA directly on the product page — their lead levels test at 0.020 micrograms per serving, far below California Prop 65 standards. They notably do not claim a specific fulvic acid percentage, arguing that natural resin varies and ‘standardized’ percentages often indicate synthetic fulvic acid was added. Nootropics Depot uses PrimaVie, a patented purified extract standardized to 60–75% fulvic acid with batch-specific reports available on request. MitoLife sources from the Altai Mountains and tests specifically for ozokerite, a common fake shilajit filler. Brands that claim 90%+ fulvic acid without a visible COA deserve your skepticism, not your money.

The Editorial Staff has reviewed a meta-analysis of 294 scientific articles on curcumin published between 2004 and 2023 (El-Saadony et al., Frontiers in Nutrition, 2023, PMC 9881416). The findings are unambiguous. Curcumin suppresses NF-κB signaling, blocking downstream inflammatory cascades including COX-2, lipoxygenase, and inducible nitric oxide synthase. It scavenges reactive oxygen species. It inhibits angiogenesis, induces apoptosis in cancer cells, and crosses the blood-brain barrier when properly formulated. Phase I trials established safety at doses up to 8,000mg per day for three months. Clinical outcomes include: reduced PSA levels in prostate cancer patients at 0.1g/day over six months; significant pain reduction in knee osteoarthritis with Theracurmin 180mg/day for eight weeks; reduced proteinuria and hematuria in lupus nephritis at 0.5g/day for three months; and a 29% increase in HDL cholesterol with 0.5g/day for seven days. Here is the problem. Free curcumin has, in the measured terminology of the pharmacological literature, ‘extremely poor bioavailability.’ A dose of 8g produces peak plasma concentrations of 1.77 ± 1.87 μM/ml. You are, statistically speaking, excreting most of what you paid for. The solution has existed for approximately 3,000 years in Indian cuisine: black pepper. Piperine, the active compound in black pepper, increases curcumin bioavailability by more than one thousandfold. This is not a marketing claim from a supplement company. This is peer-reviewed pharmacokinetics. Meriva, a curcumin-soy lecithin complex, achieves 29-fold better absorption than standard curcumin. Longvida, a solid lipid formulation, achieves four times the bioavailability and improved cognitive function at just 400mg daily over four weeks. The Editorial Staff’s position is straightforward: curcumin without piperine or an enhanced delivery system is a donation to your plumbing. Choose accordingly.

The Editorial Staff has been reading about water, which is not a sentence we anticipated writing for a deal intelligence website. But the data compelled us. Rondeau et al. (2009, PMC 2809081) followed 1,925 dementia-free elderly subjects across 91 drinking water districts in southwestern France for fifteen years. Every 10 mg/day increase in silica intake was associated with an 11% reduced risk of dementia (adjusted RR = 0.89, p = 0.036). Conversely, subjects consuming more than 0.1 mg/day of aluminum showed a 2.26-fold increased dementia risk. The mechanism is orthosilicic acid — dissolved silica in its bioavailable form. When consumed, it binds to aluminum in the gastrointestinal tract and bloodstream, forming hydroxyaluminosilicates that the body excretes through urine. It is, in effect, a chelation agent you drink with lunch. Davenward, Exley et al. (2013, PMID 22976072) tested this directly: 15 Alzheimer’s patients drank one liter per day of silicon-rich mineral water for twelve weeks. Body aluminum burden fell significantly. Three of fifteen showed clinically relevant cognitive improvement. The excretion of essential metals — iron and copper — was unaffected. The same group later studied 15 secondary progressive multiple sclerosis patients (2017, PMC 5832610): after twelve weeks of 1.5 liters daily, 14 of 15 excreted significantly more aluminum. A separate study confirmed the mechanism in honey bees (2023, PMC 9958646), suggesting prophylactic benefit when silica is consumed before aluminum exposure. Not all water is equal. Fiji Water contains approximately 93 mg/L of silica, sourced from a volcanic aquifer in the Yaqara Valley. Antipodes, from New Zealand’s Otakiri Aquifer on volcanic ignimbrite rock, contains 73–76 mg/L. Volvic contains 31.7 mg/L — better than tap, but the Editorial Staff notes this is less than half the concentration of Fiji. The research used Spritzer water (35 mg/L of silicon, roughly equivalent to 85 mg/L silica) and still achieved significant results. At 93 mg/L, Fiji is arguably overqualified. The Editorial Staff does not typically have opinions about water. We do now. If you are going to drink a liter of water today — which you should — you might as well drink one that has been clinically demonstrated to escort aluminum out of your body via your kidneys. The volcanic aquifer does not charge extra for the chelation.
