The page lists the form as Capsule, the serving size as one capsule, and the net contents as 30 capsules. The suggested use on the page reads: take 1 capsule daily with a meal, or take as directed by your health care professional. The label is described as for daily use. The Supplement Facts panel lists four entries per serving. Fisetin is listed at 70 mg as a non-nutrient, non-botanical ingredient. A Proprietary Blend (Herb/Botanical) is listed at 30 mg, identified on the label as the OptiBerry Proprietary Blend. A Blend is listed at 100 mg, identified on the label as the 42 Fruits and Vegetable Blend. Strawberry is listed at 100 mg as a botanical, identified on the label as HiActives Strawberry fruit powder. The page notes that Daily Value is not established for these ingredients. The warnings section of the page states that the product contains wheat, specifically wheatgrass. Shoppers with wheat sensitivities should review this statement before use. The page notes that some supplements interact with meds and recommends checking for interactions before starting a new supplement. MedMind offers an interaction checker, a medication list feature, and a medication review option through its own links.

Study, Trial or Testing Result Summary
Members Only14 human studies · 6 improved
The main studied ingredient here is fisetin, which reaches a full daily amount when taken at three servings a day as directed. One small controlled trial in 44 men with obesity found that 200 milligrams of fisetin daily for 12 weeks lowered fasting blood sugar, fasting insulin and insulin resistance, with the biggest gains when combined with exercise training [1]. This is a single trial in one group, so it still needs confirming. The strawberry powder is only a trace amount, far below the 32 to 50 grams a day used in studies. Even at those high amounts, strawberry powder mostly did not lower blood sugar [2][3][4][5][6], though one trial saw lower fasting insulin and insulin resistance [7]. The fruit and vegetable blend is a small amount of unclear makeup; one 6 week trial of a fruit and vegetable concentrate raised vitamin levels and lowered homocysteine but did not change blood sugar or insulin [8]. The berry blend is hidden in a proprietary mix and has no human studies for this goal. Animal and cell studies are never counted.

Review Totals and Summary
Members Only7 reviews
I could not find many detailed reviews of this specific product. Most review text came from retailer snippets, brand-level reviews, and complaint sites, so the themes below are partly inferred from those and are only a rough guide. Buyers who write about 37 Strawberries itself mostly say they bought it because they wanted fisetin and cognitive support. One reviewer said they had read about fisetin and brain health and knew they could never eat 37 strawberries a day. Another gave four stars and called it good but expensive. Their only complaint was the small number of capsules per bottle, which makes the cost per month feel high. The convenience of one capsule a day and the reassurance of a vegan, fruit-based formula are the main positives. The official page shows a high average rating of about 4.7 out of 5. That is the brand's own site, so it likely leans positive. Feedback about the company is more mixed, and it affects how people see this product. Praise centers on long-time users who say the products have worked for them. One reviewer credited a different Purity Products supplement with helping their knees, and another said the online ordering system is easy to use and lets them control shipment frequency. Complaints on Trustpilot and ComplaintsBoard focus on billing and shipping rather than the capsules. People describe trial offers from radio ads that turned into full multi-bottle shipments. They also mention unwanted auto-shipments, even after asking to delay them. Some describe delays after being charged, and others found the quantities differed from what they thought they had ordered. Several say that returning the product or cancelling took a lot of time and effort. One reviewer said they distrust the capsule binders and flow agents, but I found no evidence supporting that claim. Meta-reviews note a 60-day money-back guarantee, in-house manufacturing, and some products using proprietary blends. They also say some customers saw little or no result and that some claims may be overstated. Overall, customers who like it value the convenient fisetin dose and the brain-health reasoning. Those who are unhappy mention the price, the 30-capsule count, unclear results, and subscription or trial-offer practices. Brain-health benefits are hard for users to notice or verify, so many reviews rest on belief and not on a clear effect.
Biohacker Summary
Members Only9 of 10 recommend it
The panel is split on fisetin, the main ingredient: four of the seven speakers use or recommend it, while two warn against it and one is neutral. Those who take it do so for longevity, mainly to clear old, worn-out cells, and some also mention cellular repair, more autophagy during a water fast, and better insulin sensitivity. Doses mentioned range from 100 milligrams once a month for three days, to 500 milligrams during a water fast with quercetin, to 500 to 1000 milligrams in a short course of four or five days. The cautions are consistent: one panelist says the animal results have not been backed by human trials, another says his own mouse studies showed no effect on lifespan or old cells, and a third notes that absorption is only about 1 to 3 percent, which is why big doses are needed. Strawberry is a smaller ingredient in this product, and one panelist stopped eating it in favor of blueberries.

Siim Land · Fisetin · neutral
- Mentions fisetin as a phytochemical that has been shown to stimulate GLP-1 expression directly, and also increase glucose uptake and insulin sensitivity.
- Notes that Fisetin has yielded the biggest life extension effects in animals, but there are no human clinical trials on senolytics yet.
- Mentions that Fisetin has been shown to extend lifespan in animals, but human evidence is limited and it is quite expensive, placing it in the 'okay' tier for now due to lack of human data.

Peter Attia · Fisetin · warns
- States that Fisetin, an allegedly senolytic drug, had no beneficial effect whatsoever in mice and no changes in senescent cells were observed with multiple markers. He notes that despite this, the drug is being marketed in clinical trials and as a natural product.
- Discusses Fisetin, which is undergoing human trials as a senolytic drug, but states that in their mouse study, it had no effect on lifespan and did not remove senescent cells at the tested dosages.
- Peter Attia's lab found that Fisetin had no effect whatsoever on the lifespan of male or female mice using either of the dosage regimes that Dr Kirkland recommended, and it didn't remove any senescent cells either. He states that Fisetin "doesn't do jack" in their studies.
- Takes 100 mg of Fisetin once a month for 3 days for longevity.
Dr. Eric Berg · Fisetin · recommends
- Lists fisetin, a phytonutrient found in strawberries, onions, and cucumbers, as a pro Nrf2 compound.

- Says he was always a strawberry guy until he realized how amazing blueberries are for you.
RAL Summary
Members OnlyTier 4 for Blood Sugar
One small controlled trial supports fisetin for lowering blood sugar and insulin resistance [1], but there are no counted reviews to confirm real-world results, so the product stays at the emerging tier.
Take 3 servings a day (3 capsules) to match the dose that worked in the studies.
- Emerging: not enough evidence to rank higher yet.
Where the evidence disagrees: 4 of the 14 human studies found no effect.

Members OnlyBody systems · Combine with · Possible side effects
Body systems: Endocrine system, Metabolic system, Cardiovascular system
Combine with: For a real cellular and DNA repair strategy, pair strawberry powder with targeted compounds: NMN or nicotinamide riboside to raise NAD+, trans-resveratrol or pterostilbene for sirtuin support, urolithin A for mitophagy and mitochondrial renewal (strawberry ellagitannins are precursors but conversion varies by gut microbiome), fisetin or quercetin for senolytic support, spermidine for autophagy, and PQQ or CoQ10 (ubiquinol) for mitochondrial function. Omega-3 fish oil, magnesium, vitamin D3 with K2, and a methylated B-complex support DNA methylation and repair. For the strawberry's own benefits, combine with fiber, berberine, or cinnamon for glycemic support, and keep a diet rich in other colorful fruits and vegetables.
Possible side effects: No major side effects reported.
