Longevity Botanicals

Free delivery applies on orders over $50. Costs for smaller orders are not published, and the page quotes two slightly different delivery windows, 2 to 5 days generally and 2 to 6 business days for the US and Canada. The company is based in Canada and ships to both countries, so check the rate at checkout if your order falls below the threshold.

A 30-day guarantee applies, with customers asked to contact the company within 30 days of delivery to arrange a return or refund. The full refund policy sits on a separate linked page. Contact is via customerservice@longevitybotanicals.com; no telephone number or trading address is published, so keep a record of any correspondence.

Fruiting body only, with no mycelium and no grain, which the page states plainly. This is the most important quality question for any mushroom supplement, because mycelium grown on a grain substrate carries over large amounts of starch and contains far less beta-glucan. The extract is 10:1 and produced by hot water extraction, which is the correct method since beta-glucans sit inside chitin cell walls and need hot water to be released. Beta-D glucan content is stated at 30% or more and is printed on the pouch itself.

The company describes it as lab-verified and prints the figure on the packaging, which is more than most brands do, but no certificate of analysis is published on the site. That is the main documentation gap for an otherwise very transparent product. If you want the underlying data, email customerservice@longevitybotanicals.com and request the certificate for your batch before ordering.

The page cites two real 2026 studies by author and journal, and then does something unusual by telling you their limitations. One, by Jogi and colleagues, gave 47 adults aged 60 and over bread containing 50 g of whole maitake daily for 18 weeks, finding that one strain improved cognitive scores while the other did not. The second, by Masuda and colleagues, examined immune response and found increased dendritic cell activation in older participants. Crucially, the brand states that both used whole mushroom in food rather than a 10:1 extract powder, so the findings do not transfer directly to this product. Both studies are also small and come from the same research group. Treat maitake as a promising but not established ingredient.

One level 1.66 g scoop daily, giving 60 servings from the 100 g pouch, which works out at roughly $0.58 a serving at the sale price. Having both the serving size and the serving count stated means you can verify the cost per day yourself, which is unusual in this market. The powder can be stirred into coffee, tea or a smoothie, and beta-glucans may cause mild digestive adjustment in the first few days.

The brand advises consulting a healthcare professional if you are pregnant or breastfeeding, take prescription medication or have a health condition, which is the right guidance. One specific point is worth naming: maitake has documented blood-glucose-lowering activity, so if you take insulin, metformin or a sulfonylurea, monitor your readings carefully when starting and discuss it with your doctor, as the combination could cause hypoglycaemia. Maitake may also have mild antiplatelet effects, which matters alongside warfarin or similar medication. Anyone taking immunosuppressants should discuss immune-modulating supplements with their clinician, and mushroom allergies, while uncommon, do exist.

Every Longevity Botanicals code listed on smartstorereview is tested against the live checkout before publication and rechecked regularly, with expired codes removed and the last verified date shown beside each offer. This listing already shows a reduction from $39.99 to $34.99 and codes may not stack with sale pricing, so confirm the saving has applied. A 1 kg bulk option and several bundles are also sold, which may work out cheaper per serving if you use the powder daily.
