Arganine + Citrulline + Vitamin C
Arganine should be used in the proper ratio with Citrulline for best results, and always with vitamin C to enhance effectiveness. The combination can be taken 3 times a day, not just once per day (which we only discovered on 10-09-2022!). We also just discovered that if needed, the dose can be higher than what was previously being taken. The formula originally was 1/2 tsp arganine and not sure what it was for citrulline, but CP said he made a mistake and was using 1/2 Tbsp arganine, and that’s when the real results were seen. So I researched this tonight, to find that for ED doses up to 15,000 mg per day can be used divided over 3 doses of 5000mg each (body builders use up to 18,000 per day but we’re not going to do that), with the last right before bed time. Of course, each dose with the corresponding citrulline and Vit C. We tried this tonight and woo-hooo! The results were nearly instant, and mighty powerful! And that was without the 2nd dose during the day!

So this is the updated formula:

Dr’s Best Citrulline is cheaper, but its manufactured in China (by Dr’s Best not by a Chinese company), so I prefer Now Brand, even though its a bit more money. Apparently Dr Best owns the manufacturering facitlities, they are inspected and meet the highest standards, yadda, yadda, but I’m weary of anything from China, so we’ll play it safe and opt for Now Brand Citrulline instead.


Overall, L-arginine is believed to be a relatively safe supplement with few risk factors. Past research has found that doses as high as 15 g per day (15,000 mg) are well-tolerated. Although 15 g of L-arginine a day appears safe, it’s best to start slowly to see how you react to the supplement.

Side effects from arganine could include nausea, abdominal cramps, and diarrhea but are generally tied to higher doses of between 15 – 30 g per day when and if they occur. If you experience side effects, lower the dose.

Understanding What the Components of the Dink Drink Do:

L-arginine is an amino acid that has been shown to lower blood pressure by boosting levels of nitric oxide, a substance that relaxes blood vessels (a process called vasodilation). L-arginine has been found to be just as effective at treating high blood pressure (hypertension) as lifestyle changes like diet and exercise. 

Citrulline is an amino acid with several health benefits. It also appears to be safe and there are currently no known side effects. This supplement may promote healthier blood vessels, better blood flow throughout the body and to tissues, and lower blood pressure, especially in people with heart conditions or high blood pressure. L-arginine has been shown to help people with heart disease or clogged arteries because of its vessel-widening abilities.

Because of nitric oxide’s impact on blood flow, it plays a critical role in achieving and maintaining an erection. So anything that increases nitric oxide production—like L-arginine—can .improve erections. Nitric Oxide increases blood flow to a man’s genitals. In one study, this increase in blood flow appeared to decrease symptoms of mild ED and improve the ability to maintain an erection. There haven’t been any studies on the use of L-citrulline in moderate to severe cases of ED.|

The British Journal of Nutrition found that doses between 2 and 15 grams (g) were safe and well-tolerated by men.

L-citrulline is an amino acid that your body converts into L-arginine. You might think that supplementing with L-arginine would be more effective since it saves your body the time and effort of converting it from L-citrulline. However, our bodies deal with each of these supplements quite differently.

Both citrulline and arganine increase vasodilation – the widening of arteries or veins. It’s associated with lower blood pressure and increased blood flow.

After citrulline is consumed, some is converted to arginine. Arginine is converted into nitric oxide, which causes vasodilation of blood vessels by relaxing the smooth muscle cells that constrict them.

Consuming citrulline may increase arginine in the body more than consuming arginine itself due to differences in how the body processes and absorbs arginine and citrulline

.L-arginine supplements go through a process called first-pass metabolism (FPM), meaning your gastrointestinal tract and liver need to break them down before your body can use them. Its not an effective process: only 38% of L-arginine we get from our diets is absorbed. L-citrulline, on the other hand, doesn’t go through this process, potentially allowing it to be more available for the body to use .In one study, participants with mild ED were given 1,500 mg of L-citrulline per day. Men reported harder erections, and researchers found it to be safe and well-tolerated by study participants.

Arganine and Citrulline and commonly used in conjunction, even sold as a blend. There seems to be some variation in the ratios, from equal parts of each (1:1) to…..

There are two major forms of citrulline in dietary supplements:

  1. L-citrulline: This simply refers to citrulline by itself, with nothing else attached.
  2. Citrulline malate: This refers to the combination of citrulline and another compound called malate, which is important for energy production (9Trusted Source).

While the two forms of may produce some similar effects, citrulline malate is more common in sports supplements.

Based on current research, a recommended dose is 3–6 grams per day of L-citrulline or approximately 8 grams per day of citrulline malate.

The dose varies depending on form because 1.75 grams of citrulline malate provides 1 gram of L-citrulline. The remaining 0.75 grams are malate.

  • For improving blood pressure, the daily dose of L-citrulline used in research is typically 3–6 grams per day.

Furthermore, doses of 10 or more grams do not typically cause an upset stomach, unlike other amino acids.

Even with the highest doses (10 or 15 grams of citrulline), the participants reported no side effects .

However, the highest doses did not appear to increase arginine in the blood as much as expected, meaning there is a limit to how much of this supplement your body can use. Overall, the study indicated that doses greater than 10 grams are unnecessary.

Blood analysis performed in participants after they took citrulline supplements did not show any negative changes to normal body functions or blood pressure.

If you’re taking any other medications, it’s important you talk with your doctor about possible interactions. This is especially important in the context of other medications that also work to dilate your blood vessels. L-citrulline supplements may have additional synthetic ingredients similar to traditional ED medications. Simultaneous use of L-citrulline supplements with other vasodilatory drugs or ED drugs can cause dangerous drops in blood pressure. There is also concern that people who are taking nitrates for heart conditions may experience dangerous drops in their blood pressure when taking these supplements. So, it’s very important to always speak with your doctor before starting to take a supplement.


Here’s a new contribution to the formula as of 10-09-2022 which I did not know before: Pycnogenol (Pine Bark – much cheaper but the same thing, just not patented).


Many things have to work together in the body for an erection to happen. Important is the proper relaxation of smooth muscle in the spongy tubes of tissue in the penis that fill with blood. This process can’t happen without enough nitric oxide, which L-arginine/ Citrulline can help with. 

Pycnogenol, the patented version of an extract made from the bark of the French maritime pine tree, may also increase nitric oxide levels in the body (buy pine bark extract instead – same thing, much cheaper because not patented). One small study reported that after one month of treatment with a combination of L-arginine and pycnogenol, only 5% of study participants experienced better erections. But after three months of treatment, nearly 93% of men could experience a normal erection (Stanislavov, 2003). 

While these may be promising results, the study was a small one, and the National Institutes of Health (NIH) states that there isn’t yet enough evidence to say whether pycnogenol is truly effective for ED treatment or not (NIH, 2020).
