Someone told me to try it when it was back on the pills, they said it was better somehow. But I never did and just went for intramuscular injections instead.
I believe the benefit is that it's less stressful on your liver as opposed to providing better effects.

It should be more effective than simply swallowing, yes.
I too have found that injections are most effective.
Sublingual vs oral, got the same results in terms of feminization and how I felt although the fluctuations with sublingual bothered me a little.
Do NOT take oral pills sublingually. It can lead to an overdose or at the very least trash your liver and give you undesired results.
Pills are designed to be absorbed thru the digestive tract, and contain a larger quantity of the drug with the expectation that most of the drug will not be absorbed.

This is a decision left to the doctor. As far as I know, there are many doctors today who prescribe estradiol sublingually to their patients. Some institutions even list sublingual estradiol as being part of their protocol for feminization. http://transhealth.ucsf.edu/
Also, as mentioned before, in another post but I believe it's important to reiterate,
at most, sublingually, levels will go up to 2,000-3,000 pg/ml. Compare this to levels achieved during intramuscular injections of estradiol in transsexual women (mine are 1,000-4,000 pg/ml, clotting times remain normal, health remains good) or levels in women during pregnancy (up to 75,000 pg/ml) when risk of DVT is 0.1% and PE (pulmonary embolism) is 0.01% or consider these studies where very high levels were attained with minimal side-effects.

Estrogen acutely increases peripheral blood flow in postmenopausal women."Eleven normotensive, post-menopausal female volunteers (mean age 53 +/- 6 years) were studied.

"Subjects were given, in double-blind, randomized fashion, a sublingual placebo tablet (Mead Johnson Laboratories, Evansville, Indiana) on 1 day and sublingual estradiol-17B (Estrace (...), Mead Johnson Laboratories) on the other."

Estrogen deficiency in severe postpartum depression: successful treatment with sublingual physiologic 17beta-estradiol: a preliminary study.1) Estrofem sublingually 3 to 8 times daily for several weeks.

Fourteen (88%) were given sublingual micronized 17-beta estradiol (...) twice daily."
"one subject received estradiol valerate (...) intramuscular every 2 weeks"
"All transgender women had estradiol levels at least in the physiologic female – range at 6 months,
with 3/16 (19%) having supraphysiologic levels > 1000pg/dl (including the one transgender woman using intramuscular estradiol valerate). At 6 months, free testosterone was in the female physiologic range in 14/15 (93%), however only 10/15 (66%) had total testosterone levels in the female physiologic range (Table 4)."
Typo. It should read 1,000 pg/ML.
"Transgender women (persons assigned male at birth, but who identify as females and who use estrogens with or without an anti-androgen to develop female secondary sex characteristics) had normal median baseline and 6 month body mass index (24.8 kg/m2 (IQR=4.3) and 23 kg/m2 (IQR=4.5) respectively). Both systolic and diastolic median blood pressures in this group dropped significantly from baseline to 6 months (130.5 mmHg (IQR 11.5) to 120.5 mmHg (IQR 15.5) p=.006; 78 mmHg (IQR 21) to 67 mmHg (IQR 12), p=.001 respectively)."

There is some anxiety about the possible harmful sequelae of supraphysiological estradiol levels but no data are currently available to show any deleterious effects of these levels on coagulation factors, blood pressure, glucose tolerance or the occurrences of endometrial or breast cancer (Hammond et al. 1974; Thom et id. 1978; Studd B Thom 1981; Armstrong 1988)."
"Increased levels of oestradiol may be beneficial, not only for their anti-depressant effect, but also in their effect upon bone density. The latter is greater after implant therapy than after oral therapy and is related to the greater plasma oestradiol levels achieved in women with implants. None of the 38 patients complained of alleged symptoms 01 oestrogen excess, such as breast tenderness, fluid retention or nausea."
"Supraphysiological oestradiol levels are an uncommon consequence of oestradiol implants occurring most frequently in women with a history of depression or surgical castration.
These high serum oestradiol levels were not associated with any deleterious effects and may be necessary for the control of symptoms in specific women"

Beneficial effect of oestrogen on exercise-induced myocardial ischaemia in women with coronary artery disease."
We have studied the acute effect of sublingual oestradiol-17 beta on exercise-induced myocardial ischaemia in eleven women (mean age 58 [SD 8] years) with coronary artery disease."
"Plasma oestradiol-17 beta concentrations were confirmed to be higher after sublingual oestradiol-17 beta than after placebo (2531 [1192] vs 155 [168] pmol/L, p < 0.001). Oestradiol-17 beta increased both time to 1 mm ST depression (456 [214] vs 579 [191] s, p < 0.004; difference of medians 92 [95% CI 46-254]) and total exercise time (569 [249] vs 658 [193] s, p < 0.01; difference 54 [10-212]). Acute administration of oestradiol-17 beta therefore has a beneficial effect on myocardial ischaemia in women with coronary artery disease. This effect may be due to a direct coronary-relaxing effect, to peripheral vasodilation, or to a combination of these mechanisms.
Oestradiol-17 beta may prove to be a useful adjunct to the treatment of angina in postmenopausal women with coronary heart disease."

"The mean serum levels of oestradiol increased from a control level of 72 +/- 28 pmol.l-1 to 3557 +/- 1731 pmol.l-1 after 30 min and to 5028 +/- 3971 pmol.l-1 after 60 min with a gradual decline thereafter. Sublingual 17 beta-oestradiol did not induce any improvement in exercise duration when compared with nitroglycerin and placebo (500 +/- 112 s, 505 +/- 107 s, 498 +/- 157 s), and did not influence time to onset of ST-segment depression (358 +/- 89 s, 436 +/- 93 s, 384 +/- 116 s). The plasma levels of endothelin-1 did not change after administration of 17 beta-oestradiol, nitroglycerin or placebo."
No improvement but no adverse effects either.

At rest a slight drop in systolic and diastolic blood pressure was measured after estrogen ingestion: 132 +/- 24 mm Hg versus 127 +/- 21 mm Hg, p < 0.05; 83 +/- 11 mm Hg versus 78 +/- 10 mm Hg, p < 0.02. There were no changes in resting heart rate, double product, or vascular resistance. The left heart cavities became smaller: the left atrium diameter decreased from 33.7 +/- 4 mm to 32.3 +/- 4 mm, p < 0.01; the end-systolic diameter decreased from 24.9 +/- 3 mm to 23.6 +/- 4 mm, p < 0.01; the end-diastolic diameter decreased from 44.5 +/- 4 mm to 42.7 +/- 4 mm, p < 0.01. The peak aortic blood flow velocity fell from 120 +/- 19 cm/s to 116 +/- 22 cm/s (p < 0.05), and the flow velocity integral fell from 26.3 +/- 4 cm to 24.9 +/- 5 cm (p < 0.01); the cardiac output underwent a small change, with borderline significance: 7 +/- 2 L/min versus 6.7 +/- 2 L/min, p = 0.06. Only minor changes in the hemodynamic and echocardiographic parameters were recorded after estrogen for both isometric and dynamic exercises. Analyses were also made for two subgroups: 13 normotensive women were compared with 11 hypertensive women. The post-estrogen decreases in resting blood pressure and in peak blood velocity were observed only in the hypertensive subjects, whereas the changes in heart dimensions and in flow velocity integral were the same in both subgroups."
