spermidineLIFE is a food supplement that is meant to be taken in conjuction with a balanced diet, meaning it's not meant to replace anything.You can definitely get comparable amounts of spermidine from food sources such as wheat germ, they just aren't as consistent or reliable as a regulated product. If you follow a spermidine-rich diet then you might not need to supplement at all. Many people just choose to supplement naturally via pill form, rather than having to find ways to calculate out how much they need to eat of which foods.
SpermidineLIFE is an extract, meaning that it's not ground-up wheat germ. The extraction process isolates the spermidine to make the concentration much greater (per gram) than any non-extract product. When comparing our product to wheat germ, we generally see between 5-100x the amount of spermidine in the same sample size. But again, wheat germ can vary greatly from sourcing and crop cycles.
We can’t speak to a competitor product, but if you were to take 100g of our product, it would contain 125mg of spermidine.
