Ingredients and Nutritional Information
As a testament to the purity of the product, there is only one active ingredient in capsule: theacrine. According to the supplement facts sheet, the listed ingredient is simply Theacrine Powder. Each serving amounts to 75 of Theacrine (as TeaCrine.) According to the sheet, there is no recommended daily value for Theacrine intake.
Double Wood Supplements – Theacrine Benefits
According to the ingredients list of the product, there is only one ingredient present in the capsules: Theacrine. Below are the supposed benefits of Theacrine.
Theacrine is listed as a nootropic, that is, a substance that can improve mental prowess and functions. Like caffeine, it is a very natural chemical that is present in tea, coffee, exotic fruits, and very specific natural sources like Camellia assamica var.kucha tealeaf. (1, 2)
Theacrine is traditionally consumed orally for many reasons, from curing the simple cold to actually allegedly extending one’s lifespan. But these days, modern science has studies that shows theacrine as a substance that can improve energy levels, increase fatigue resistance, and augment the physical and mental performance of people engaged in physical and athletic abilities. This is why pre-workout drinks, tablets, capsules, and gels have included theacrine over the years.
How does theacrine work?
A number of different research studies yielded results showing that theacrine stimulates the central nervous system similarly to how caffeine does it. When theacrine doses are high the activity of the central nervous system spikes up, and when the theacrine doses are low the central nervous system activity lowers as well. (3, 4)
There is however a difference between caffeine and theacrine. That is, at least one study has shown that a person’s blood pressure is not affected by theacrine, unlike how caffeine can increase one’s heart rate and blood pressure. This makes theacrine suited for people with heart-related issues who still want the benefits that caffeine gives. (5)
Despite the numerous scientific studies showing the possible effects of theacrine, there is however not enough evidence to fully support all the claims made by the makers of theacrine supplements, for now at least. This could be from not having sufficient research done yet at this point, for example. But most primary studies done have yielded the following results.
- Theacrine increases mental capacity and thinking speed – a study has yielded evidence that taking one dose of products like Theacrine (Teacrine) – Energy and Stamina Boosting Supplement can benefit a regular person by improving their mental capacity, focus, and clarity of thought. It does however take more than a few days of taking doses to fully experience the effect. (8)
- Theacrine improves physical capability – some studies have yielded results showing that at least one dose of products like Theacrine (Teacrine) – Energy and Stamina Boosting Supplement improves the energy levels of most average people. It also has the added benefit of improving one’s resistance to fatigue and tiredness. But the results are varied at best, and it is generally recommended to take the product constantly for at least seven days to fully feel the effects. (9, 10)
- Theacrine fights aging and other ailments like colds – this is a traditional belief of the benefits of theacrine as found in teas and fruits. However, as of the writing of this review, no studies have shown the efficacy of theacrine in slowing down the aging process or fighting the cold virus.
Not enough studies have been done to show the possible side-effects of Theacrine consumption. However, there have been reports of users experiencing various side-effects, ranging from Theacrine not being an effective stimulant, to having a reverse effect and making one sleepy, to causing various mood swings from irritability to anxiety and everything in between.
These can all be attributed to wrong dosing, as studies have already shown that theacrine in low doses can cause the central nervous system activity to be lowered. But regardless, even if those are the only possible side-effects, people with prior medical conditions, as well as pregnant and breast-feeding women, should play it safe and not consume any Theacrine products.
How Much Should I Take?
When taking a new supplement or natural product it is always best to start at the lowest recommended dose by the product maker. This will allow you some buffer time to see if you will experience any negative side-effects from this product. According to the manufacturer, Double Wood Supplements, the lowest dose is 1 capsule in the morning. And they do recommend going beyond 400mg per day.
Once seven days have passed with no negative effects you can push to two capsules in the morning as per the maker’s recommendation. Just keep in mind that supplements like these that are made 100% natural may need time to be effective.
And also, just because there’s no immediate side-effects doesn’t mean you might not feel them as you’re using the product down the line. Pay attention to your body’s reactions because even plant-based, natural supplements can still cause some negative results. (11, 12)
Best Time To Take Double Wood Supplements – Theacrine
According to the manufacturer, the best time to take a capsule is in the morning. However, some users have reported feeling benefits when taking one capsule in the morning, and one later on in the day. Especially for those who work late shifts or have other activities planned after.
Why Double Wood Supplements – Theacrine?
In addition to being made of 100% Theacrine with no other product fillers, it is also made in the USA which means it has passed very strict quality and safety standards.
The disadvantage of just having 100% Theacrine is if it doesn’t work for you, no other ingredients in the capsule can pick up the slack. But in general, users can attest to the product’s effectiveness. The only way to see if the product works for you is to try it yourself.
How Much Does It Cost?
One bottle costs $19.95 for 60 capsules.
One can either take 1 capsule or 2 capsules per serving, usually mornings.
One capsule per day dosing will last 60 days. Two capsules will last 30. It amounts to $0.33 or $0.66 per day respectively. The price is quite reasonable, especially since it is claimed to be 100% Theacrine.
