Dentin is mineralized tissue with a collagen-containing matrix
Dentin forms much of the tooth beneath enamel. Its mineral and organic components make it different from both the outer enamel and the soft inner pulp.
DHEA: a hormone precursor, not a routine anti-aging supplement
Changes in hormone levels do not establish better strength, memory or long-term health.
What supplements block DHT for hair loss?
A product advertised as a natural DHT blocker is not necessarily an effective hair-loss treatment. Saw-palmetto research for male-pattern hair loss is too limited for a firm conclusion. A dermatologist can identify the type of hair loss and discuss treatments with clearer clinical evidence.
DoNotAge collagen peptides: what the evidence supports
DoNotAge’s inspected powder contains hydrolysed bovine collagen types I and III, with 10 g collagen per stated scoop. It is a defined protein product, but the brand name and collagen content do not prove anti-aging effects or superiority over other powders.
Do elastin supplements work for skin?
A small randomized trial of one fish-derived elastin peptide reported improved skin measurements after 12 weeks. That is preliminary, product-specific evidence, not proof that all elastin supplements reverse skin aging or rebuild elastic fibers.
Ergothioneine: what the longevity-vitamin label does and does not mean
Ergothioneine is a histidine-derived compound found in foods such as mushrooms. Antioxidant chemistry and ingredient safety assessments do not establish longer human lifespan.
Eriomin and prediabetes: what a twelve-week trial measured
Short-term metabolic changes do not establish durable diabetes prevention.
What is ESS60? C60 supplement science and limitations
ESS60 is a commercial designation for a processed form of C60, a carbon fullerene, sold in oil-based products. Manufacturer descriptions and animal longevity claims do not establish that it extends human life or is safe for indefinite use.
What ethyl ascorbic acid is, and why formulation matters
This vitamin C derivative is used in topical products. Laboratory evidence shows that the surrounding formulation affects its delivery, without establishing a universal clinical advantage.
What fascia is made of: cells within an organized connective matrix
Fascia is connective tissue, not a sheet of pure collagen. Its fibers, hydrated matrix and cells vary with the anatomical layer and function.
Ferulic acid is not vitamin C, even when they share a serum
They are different compounds. Ferulic acid can be part of an antioxidant formulation containing vitamin C, but its presence does not make the ingredients interchangeable.
Fish oil for heart health: food, supplements and prescriptions differ
Fish can fit a heart-healthy dietary pattern, while prescription omega-3 medicines have specific clinical uses. That does not mean cardiologists recommend an ordinary fish-oil capsule to every person. The expected benefit depends on cardiovascular risk, the preparation and the outcome being treated.
Fish oil for high cholesterol: LDL and triglycerides can move differently
Fish oil should not be treated as a general LDL-cholesterol treatment. Its clearer lipid effect is triglyceride lowering, particularly with prescription preparations. Some products can increase LDL, so the full lipid panel and treatment goal matter.
Which foods contain the most glutathione?
Asparagus, avocado and spinach are among the richer plant foods in published analyses. Some mushrooms, meats and seafood also contain substantial amounts. There is no dependable universal ranking: variety, preparation, analytical method and whether a value refers to fresh or dried food change the comparison.
Foods for hair health: meet nutritional needs without promising prevention
Enough food, protein, iron and zinc can matter when inadequate nutrition contributes to hair loss. No food list can prevent every cause of shedding or replace assessment of a changing scalp or hair pattern.
Gelatin before exercise: a collagen-synthesis marker is not injury prevention
A short experiment found biochemical and engineered-tissue changes after vitamin C-enriched gelatin and exercise. It did not count prevented injuries.
Ginkgo for memory: prevention and symptom treatment are different questions
Ginkgo has not been shown to prevent dementia. Evidence about symptoms in established dementia is inconsistent, and that question should not be substituted for prevention or cognitive enhancement in healthy people.
GLA supplements: oil sources, evidence and label amounts
Gamma-linolenic acid, or GLA, is an omega-6 fatty acid found in oils such as evening primrose, borage and black currant oil. The total oil amount is not the same as its GLA content, and evidence about one preparation does not establish every claimed use.
Glucosamine: keep the salt, combination and joint outcome distinct
Compare preparation-specific evidence without turning a cartilage-related ingredient into a promise of joint repair.
GAIT: glucosamine and chondroitin did not meet the overall pain endpoint
The overall trial was negative for the supplements. A favorable exploratory subgroup should retain that label.
Glucosamine for chronic low-back pain: disability did not improve more than placebo
A six-month treatment trial found no significant advantage in pain-related disability, pain or quality of life.
RE-ENERGIZE: glutamine did not speed recovery from severe burns
A large trial did not confirm a faster discharge alive from hospital.
Oral glutathione and body stores: a biomarker trial
A six-month trial reported increased glutathione in measured compartments. It did not establish prevention of illness.
Does glutathione lower cholesterol?
The reviewed evidence does not establish glutathione as a reliable cholesterol-lowering treatment. Its antioxidant role and research in metabolic liver disease do not show that a supplement produces a clinically meaningful LDL reduction or prevents cardiovascular events.
