Sage is an herb with a variety of uses. People use sage in tasty dishes, for cleaning, and as a ritual object in spiritual practices. It’s available in oil, fresh, or dried forms – and has fantastic benefits for your brain.
Also known as common sage, Salvia officinalis, and garden sage. It’s one of the staple herbs in cuisines around the world.
If you ever tasted sage before, you know it has a unique aroma and flavor. And even though it’s only used in small amounts, you’d be surprised at how healthy and nutritious sage is.
In this post, I’ll explain 5 proven sage brain benefits – drawing upon scientific studies to show you how this herb supports your cognitive health.
1. Protects Brain Cells
Antioxidants are compounds that help your body fight off disease, stress, and aging. They work by neutralizing harmful free radicals that wreak havoc on your cells, including those in the brain. (1)
Sage contains 160 unique antioxidants. These include chlorogenic acid, caffeic acid, ellagic acid, rutin, and rosmarinic acid. (2)
These plant polyphenols are shown to improve memory and brain function, along with protecting your neurons from the wear and tear of aging. (3, 4)
2. Improves Memory
As we saw, sage protects our brain cells with its antioxidants. This effect by itself is beneficial for our memory.
However, sage also halts the destruction of acetylcholine (ACH). This is your brain’s chemical messenger that regulates memory and cognition. People with Alzheimer’s are shown to have low ACH levels. (5, 6)
In the end, the results showed that those who took a sage extract saw improvements in their reasoning, memory, problem solving and general cognitive performance. Unlike the placebo group which saw no changes. (7)
3. Boosts Mood
Besides boosting up your memory function, sage is also shown to help with mood.
In one study, healthy adults who took low doses of sage quickly saw improvements in their memory. But then, once these people increased their doses, they also experienced a lift in their mood. Specifically, their alertness, happiness, and calmness all improved. (8)
Now, sage also positively affects blood sugar and insulin sensitivity. This is important because blood sugar spikes lead to mood swings and energy crashes. By keeping your blood sugar levels stable, sage effectively keeps your mood stable too. (9)
And as per anecdotal evidence, sage can help you fall asleep faster as well. Many people use it successfully for insomnia.
4. High in Brain-Feeding Nutrients
As we briefly talked above, sage packs quite a punch. Just one teaspoon of ground sage (around 0.7g) will provide you with these nutrients (10):
- Vitamin K: 10% of the RDI
- Vitamin B6: 1.1% of the RDI
- Manganese: 1% of the RDI
- Iron: 1.1% of the RDI
- Calcium: 1% of the RDI
This only comes with 2 calories, 0.4g being carbs, 0.1g protein, and 0.1 fat.
As you can see, there’s plenty of vitamin K in one teaspoon of sage. Which is fantastic, because “K” is important for brain health. Specifically, your brain needs it to make sphingolipids – fatty acids that cover your brain cell membranes.
5. Strengthens Focus
In most studies, sage consistently shows its ability to boost brain health and function. In both younger and older people.
Now, one study wanted to test the acute effects of a sage extract on mental performance. They took 20 people and split them into two groups. As usual, one group took a placebo, while the other group received four active sage extract doses: 166, 333, 666, and 1332 milligrams.
People who took sage were able to concentrate better and stay focused on tasks significantly longer than the placebo group. (11)
The follow-up in-vitro analysis showed that sage extract inhibited acetylcholine breakdown in the brain. In other words, sage helped to maintain high ACH levels, which in turn positively affected the participant’s focus and concentration.
Sage Side Effects
Sage is generally a safe herb. I didn’t come across any reports about side effects in humans. (1)
However, some people ask if thujone, a chemical found in common sage, is harmful. Some rat studies show that it can be neurotoxic in high doses.
But evidence doesn’t show any negative effects of thujone on humans.
What’s more, you’d need to consume near impossible amounts of sage to reach the toxic levels of thujone.
Still, ingesting sage essential oils or drinking too much sage tea – which you should avoid in any case – may be toxic. So if you want to be on the safe side, don’t drink more than 3-6 cups of sage tea per day.
If you want to avoid thujone altogether, then you can simply opt for Spanish sage instead. As it doesn’t have any thujone in it.
How Much Sage is too Much?
There’s no defined rule for how much sage is too much. It also depends on the type of sage you use. Avoid ingesting sage essential oils or drinking more than 6 cups of common sage tea per day. You can also opt for Spanish sage which is a variant that is known to be even safer than common sage.
Is Sage Good For Anxiety?
It is. Sage helps to calm nerves and improve mood. It achieves this by stabilizing your blood sugar levels, along with supporting healthy brain chemistry.
Are Sage Tablets Safe?
This depends on what kind of tablets you buy. Sage tablets that come from reputable and established supplement companies are generally considered safe. Despite this, you should do a proper research and consult with your doctor before adding any kind of supplement to your lifestyle. Especially if you have or suspect a medical condition!
Sage is an amazing herb with soothing and memory-boosting benefits for the brain. However, it’s worth noting that there’s no magical herb or pill that will solve everything for you.
You should always have your diet, sleep, and exercise on point before looking for other ways of ‘biohacking’. Along with consulting with your healthcare practitioner every once in a while if you have any questions.
