Study, Trial or Testing Result Summary
Members Only1 human studies · 0 improved
Only one small human study bears on chlorophyll for aging and DNA repair, and it does not show that chlorophyll reverses aging. In a crossover trial, 12 healthy women took chlorella tablets supplying about 100 milligrams of chlorophyll a day, or a placebo, for 2 weeks each. Overall DNA methylation, a chemical tagging pattern on DNA, was lower with the chlorella tablets than with placebo. Methylation at two specific genes did not change, and no biological aging clock was measured, so the study cannot say whether biological age changed [1]. The study used a whole algae product rather than chlorophyll alone, so it is unclear how much of the effect came from chlorophyll itself [1]. This product gives 70 milligrams of chlorophyll a day, which is below the roughly 100 milligrams in that study [1]. Because the only study was very small, short, used a different source of chlorophyll and had mixed results, the evidence that this product reverses aging or repairs DNA is too thin to draw conclusions. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
Six of the ten panelists spoke about chlorophyll, and they are split: two currently recommend it, one uses it, three are neutral, and one now warns. Those in favor take it for gut soothing and ulcer relief, mold toxin support, antioxidant and energy claims, and as a way to get magnesium from leafy greens. Forms mentioned include liquid chlorophyll on an empty stomach, chlorophyllin, water soluble chlorophyll between meals, algae, and chlorophyll water at about 20 ounces a day. One panelist said there is no solid evidence it is as amazing as claimed, and another warned that injecting it into the eyes for night vision has scant human research and cannot be reversed. One panelist does not take it as a supplement and eats chlorophyll-rich greens instead, and no one gave a pairing beyond taking it between meals or on an empty stomach.

Dave Asprey · Chlorophyll · neutral
- Mentions that longer shading before harvest builds more chlorophyll into the matcha leaf.
- States that chlorophyll is an antioxidant that can get into the mitochondria.
- Dave Asprey recommends chlorophyll because it is an antioxidant that can get into the inner membrane of the mitochondria, which is crucial for mitochondrial health.
- References research suggesting that if one eats enough chlorophyll from green vegetables, up to 5% of energy requirements can be met by mitochondria using sunshine instead of food.
- Drinks about 20 oz of chlorophyll water every day, which they believe contributes to keeping stench at bay.
- Mentions chlorophyll detox water as an elixir that people are currently sipping.
Ben Greenfield · Chlorophyll · warns
- Gives injecting chlorophyll into the eyeballs for night vision as an example of a medical protocol with scant human research that is not reversible.
- May start to consume more chlorophyll from algae to elevate his iron and ferritin levels.
- Introduces chlorophyll and discusses how its intake can manage excess acidity, inflammation, and accelerated aging.
- Recommends chlorophyll-rich compounds, stating that a lack of chlorophyll in one's diet tends to be a leading cause of various diseases and accelerated aging, and that it can produce ATP when combined with sunlight, contributing to cleaner energy and longevity.
- Ben recommends taking water soluble chlorophyll between meals.
- States that chlorophyll, especially from eating wild plants, is one of the best ways to keep one young based on scientific research.
- States that chlorophyll is an amazing blood builder, having the exact same molecular structure as hemoglobin, with the only difference being a magnesium core instead of an iron core.
- Ben discusses research suggesting that chlorophyll content in the bloodstream, combined with sunlight, can assist with ATP production in the absence of calories, similar to how plants produce energy.
- Mentions that supplementing with copper chlorophyllin could help with the odor associated with trimethylaminuria.
- Ben discusses a new study on chlorophyll, noting that consuming chlorophyll-rich foods like dark leafy greens and then being exposed to infrared radiation, particularly from sunlight, can lead to ATP production similar to consuming calories.
Dr. Eric Berg · Chlorophyll · recommends
- Suggests trying chlorophyllin as a remedy if one suspects fungus or mold toxicity.
- Recommends chlorophyllin, a liquid version of chlorophyll, to help neutralize the effect of mold toxins.
- Recommends natural remedies such as liquid chlorophyll to help soothe stomach irritation and find relief from stomach pain.
- Recommends liquid chlorophyll on an empty stomach as a great healer for ulcers and irritation in the esophagus, helping to heal any lesions.
- Recommends using chlorophyll to help heal ulcers or gastritis.
- Suggests chlorophyll as a natural solution for silent reflux.
- Notes that 70% of wheatgrass is chlorophyll and that chlorophyll has beneficial properties.
- Notes that chlorophyll, found in products like wheatgrass juice powder or leafy greens, can react with iodine and turn the substance brown, not purple.
- Recommends chlorophyll as a phytonutrient that is really good to protect the kidney.
- Recommends chlorophyll, specifically a high-quality raw wheatgrass juice powder, to heal stomach inflammation or ulcers before resuming apple cider vinegar.
Thomas DeLauer · Chlorophyll · neutral
- States that while chlorophyll isn't bad, there isn't solid evidence that it's as amazing as everyone claims, and being green doesn't mean we get the same benefits as plants.
- Recommends chlorophyll, found in spinach, for benefits in red blood cell health, cellular healing, and chelating heavy metals like excess iron and mercury.
- Notes that matcha green tea has a huge boost in chlorophyll, which is very powerful at detoxing within the body, chelating heavy metals and toxins stuck to colon walls.
Dr. Mark Hyman · Chlorophyll · neutral
- Mentions that upon ingestion of chlorophyll rich compounds combined with sunlight, a similar effect of producing energy was observed.
Dr. Rhonda Patrick · Chlorophyll · uses
- Eats a ton of chlorophyll-containing leafy greens because magnesium is at the center of the chlorophyll molecule.
- Dr. Patrick recommends increasing the consumption of green chlorophyll-containing vegetables to combat magnesium deficiency.
- States that magnesium is found at the center of a chlorophyll molecule, which means it's found in green plants like spinach and kale, but does not personally take chlorophyll and cannot recommend a form.
RAL Summary
Members OnlyTier 4 for Healthy Aging
Tier 4 because the only human study is one tiny two week trial of chlorella tablets with mixed results on DNA methylation and no aging clock measured [1], and there are no reviews.
- Emerging: not enough evidence to rank higher yet.
